Alternating ibuprofen and acetaminophen in the treatment of febrile children: a pilot study [ISRCTN30487061]

Female healthcare providers’ knowledge, attitude, and practice towards cervical cancer screening and associated factors in public hospitals of Northwest Ethiopia

Objective:

Cervical cancer is the fourth most common gynaecological cancer in the world. Its incidence and burden are high in developing regions, especially in sub-Saharan Africa. The World Health Organization plans to increase vaccination, screening, and treatment of cases to 90%, 70%, and 90%, respectively, in developing countries by 2030. Therefore, the aim of this study was to assess knowledge, attitudes, and practices of cervical cancer screening and predictors among female healthcare providers.

Methods:

Institution-based cross-sectional survey was done from 4 March to 20 April 2019. The data were collected using a structured questionnaire. The data were entered into EpiData version 3.1 and analysed with SPSS version 25. Logistic regression analysis was used to identify associations. After controlling for confounders, an independent association was declared at a p-value of 0.05 with a 95% confidence interval.

Results:

Of a total of 404 participants, half were nurses. One hundred seventy-seven (43.8%) had adequate knowledge, 124 (30.7%) had a favourable attitude, and 35 (8.7%) had regular screening practice. The availability of trained personnel in the health facility and regular screening were variables associated with knowledge. Participants’ attitude was shown association with profession, level of education, and knowledge. Moreover, knowledge of the causes of cervical cancer and knowledge of screening were variables significantly associated with screening practice.

Conclusion and recommendations:

Unfortunately, there is low adequate knowledge, low favourable attitude, and irregular screening practice of cervical cancer in the study area. Despite their own effects, their knowledge and attitude may affect the vast majority of their clients. Therefore, this finding calls for prompt action, such as training for participants to increase awareness, to shape their attitudes, and to increase the uptake of screening services.

Acetaminophen and ibuprofen in the treatment of pediatric fever: a narrative review

OBJECTIVE

A narrative review of randomized, blinded, controlled studies assessing the antipyretic effect of ibuprofen versus acetaminophen or combined or alternating treatment in children was conducted.

METHODS

Searches of the PubMed and Embase literature databases were conducted to identify relevant articles. Selected articles were limited to studies published in English that investigated OTC oral tablet and syrup formulations of acetaminophen and ibuprofen; there were no publication date limits. Open-label studies, nonrandomized studies, and those evaluating intravenous or suppository formulations of acetaminophen or ibuprofen were excluded. Variations in designs, endpoints, methods, and patient populations precluded our ability to conduct a formal systematic review.

RESULTS

At physician-directed dosing (acetaminophen 15 mg/kg vs ibuprofen 10 mg/kg), no significant differences in antipyretic effects from 0‒6 h and between 0‒6, ‒12, ‒24, or ‒48 h, with single or multiple-doses, respectively, were observed. Tolerability profiles at physician dosing were similar. In 14 over-the-counter dose comparisons (acetaminophen, 10-15 mg/kg; ibuprofen, 2.5-10 mg/kg), antipyresis favored ibuprofen in 6, was similar between groups in 7, and favored acetaminophen (15 mg/kg vs ibuprofen 5 mg/kg) in 1 comparison. Both medications were well tolerated. Efficacy favored combination over individual components in 3 of 4 studies; alternating use results were mixed. All combination or alternating treatments were well tolerated.

CONCLUSIONS

Antipyretic effects of ibuprofen and acetaminophen are similar at physician-directed doses; ibuprofen may be modestly superior at over-the-counter doses.

Comparative Analysis of Single and Combined Antipyretics Using Patient-Generated Health Data: Retrospective Observational Study

BACKGROUND

Fever is one of the most common symptoms in children and is the physiological response of the human immune system to external pathogens. However, effectiveness studies of single and combined antipyretic therapy are relatively few due to lack of data. In this study, we used large-scale patient-generated health data from mobile apps to compare antipyretic affects between single and combination antipyretics.

OBJECTIVE

We aimed to establish combination patterns of antipyretics and compare antipyretic affects between single and combination antipyretics using large-scale patient-generated health data from mobile apps.

METHODS

This study was conducted using medical records of feverish children from July 2015 to June 2017 using the Fever Coach mobile app. In total, 3,584,748 temperature records and 1,076,002 antipyretic records of 104,337 children were analyzed. Antipyretic efficacy was measured by the mean difference in the area under the temperature change curve from baseline for 6 hours, 8 hours, 10 hours, and 12 hours after antipyretic administration in children with a body temperature of ≥38.0 ℃ between single and combination groups.

RESULTS

The single antipyretic and combination groups comprised 152,017 and 54,842 cases, respectively. Acetaminophen was the most commonly used single agent (60,929/152,017, 40.08%), and acetaminophen plus dexibuprofen was the most common combination (28,065/54,842, 51.17%). We observed inappropriate use, including triple combination (1205/206,859, 0.58%) and use under 38 ℃ (11,361/206,859, 5.50%). Combination antipyretic use increased with temperature; 23.82% (33,379/140,160) of cases were given a combination treatment when 38 ℃ ≤ temperature < 39 ℃, while 41.40% (1517/3664) were given a combination treatment when 40 ℃ ≤ temperature. The absolute value of the area under the curve at each hour was significantly higher in the single group than in the combination group; this trend was consistently observed, regardless of the type of antipyretics. In particular, the delta fever during the first 6 hours between the two groups showed the highest difference. The combination showed the lowest delta fever among all cases.

CONCLUSIONS

Antipyretics combination patterns were analyzed using large-scale data. Approximately 75% of febrile cases used single antipyretics, mostly acetaminophen, but combination usage became more frequent as temperature increased. However, combination antipyretics did not show definite advantages over single antipyretics in defervescence, regardless of the combination. Single antipyretics are effective in reducing fever and relieving discomfort in febrile children.

Comparison of Fever-reducing Effects in Self-reported Data from the Mobile App: Antipyretic Drugs in Pediatric Patients

We compared the fever-reducing efficacy of acetaminophen (AA), ibuprofen (IBU), and dexibuprofen (DEX) using data collected from the mobile healthcare application FeverCoach, which provides parents with guidelines for determining their child’s health condition, according to body temperature. Its dataset includes 4.4 million body temperature measurement records and 1.6 million antipyretics treatment records. Changes in body temperature over time were compared after taking one of three different antipyretics (AA, IBU, and DEX), using a one-way ANOVA followed by a post-hoc analysis. A multivariate linear model was used to further analyze the average body temperature differences, calibrating for the influences of age, weight, and sex. Children administered IBU had average body temperatures that were 0.18 °C (0.17–0.19 °C), 0.25 °C (0.24–0.26 °C), and 0.18 °C (0.17–0.20 °C) lower than those of children administered AA, at time intervals of 1–2 hours, 2–3 hours, and 3–4 hours, respectively. Similarly, children administered DEX had average body temperatures that were 0.24 °C (0.24–0.25 °C), 0.28 °C (0.27–0.29 °C), and 0.12 °C (0.10–0.13 °C) lower than those of children administered AA, at time intervals of 1–2, 2–3, and 3–4 hours, respectively. Although the data were collected from the application by non-professional parents, the analysis showed that IBU and DEX were more effective in reducing body temperature than AA was.

Prescribing Controversies: An Updated Review and Meta-Analysis on Combined/Alternating Use of Ibuprofen and Paracetamol in Febrile Children

Background: Ibuprofen and paracetamol are the only antipyretics recommended in febrile children. According to international guidelines the choice of the drug should rely on the child's individual characteristics, while a controversial issue regards the combined or alternate use of the two drugs. Objective: To compare the efficacy and safety of combined or alternating use of ibuprofen and paracetamol in children. Methods: A systematic review of literature was performed on Medline and Embase databases. The included studies were randomized controlled trials analyzing the efficacy of combined or alternating therapy with antipyretics in febrile children vs. monotherapy. A meta-analysis was performed to measure the effect of treatment on child's temperature and discomfort. Adverse effects were analyzed as secondary outcome. Results: Nine studies were included, involving 2,026 children. Mean temperature was lower in the combined therapy group at 1 h (mean difference: -0.29°C; 95%CI: -0.45 to -0.13) after the initial administration of therapy. No statistical difference was found in mean temperature at 4 and 6 h from baseline. A significant difference was found in the proportion of children reaching apyrexia at 4 and 6 h with the combined treatment (RR: 0.18, 95%CI: 0.06 to 0.53, and 0.10, 95%CI: 0.01-0.71, respectively) and at 6 h with alternating treatment (RR: 0.30, 95% CI: 0.15-0.57), compared to children treated with monotherapy. The child's discomfort score was slightly lower with alternating therapy vs. monotherapy. The pooled mean difference in the number of medication doses per child used during the first 24 h was not significantly different among groups. Discussion: Combined or alternating therapy resulted more effective than monotherapy in reducing body temperature. However, the benefit appeared modest and probably not clinically relevant. The effect on child discomfort and number of doses of medication was modest as well. According to our findings, evidences are not robust enough to encourage combined or alternating paracetamol and ibuprofen instead of monotherapy to treat febrile children, reinforcing the current recommendation of most of the international guidelines.

Alternating Acetaminophen and Ibuprofen versus Monotherapies in Improvements of Distress and Reducing Refractory Fever in Febrile Children: A Randomized Controlled Trial

BACKGROUND

No evidence can be found in the medical literature about the efficacy of alternating acetaminophen and ibuprofen treatment in children with refractory fever.

OBJECTIVE

Our objective was to assess the effect of alternating acetaminophen and ibuprofen therapy on distress and refractory fever compared with acetaminophen or ibuprofen as monotherapy in febrile children.

METHODS

A total of 474 febrile children with axillary temperature ≥38.5 °C and fever history ≤3 days in a tertiary hospital were randomly assigned to receive either (1) alternating acetaminophen and ibuprofen (acetaminophen 10 mg/kg per dose with shortest interval of 4 h and ibuprofen 10 mg/kg per dose with shortest interval of 6 h and the shortest interval between acetaminophen and ibuprofen ≥2 h; n = 158), (2) acetaminophen monotherapy (10 mg/kg per dose with shortest interval of 4 h; n = 158), or (3) ibuprofen monotherapy (10 mg/kg per dose with shortest interval of 6 h; n = 158). The mean Non-Communicating Children's Pain Checklist (NCCPC) score was measured every 4 h, and axillary temperatures were measured every 2 h.

RESULTS

In total, 471 children were included in an intention-to-treat analysis. No significant clinical or statistical difference was found in mean NCCPC score or temperature during the 24-h treatment period in all febrile children across the three groups. Although the proportion of children with refractory fever for 4 h and 6 h was significantly lower in the alternating group than in the monotherapy groups (4 h: 11.54% vs. 26.58% vs. 21.66%, respectively [p = 0.003]; 6 h: 3.85% vs. 10.13% vs. 17.83%, respectively [p < 0.001]), the mean NCCPC score of children with refractory fever for 4 or 6 h was not lower than those in either of the monotherapy groups. The number of patients who developed persistent high body temperature was consistent across all study groups.

CONCLUSIONS

Alternating acetaminophen and ibuprofen can reduce the proportion of children with refractory fever, but if one cycle of alternating therapy cannot reduce febrile distress as defined by NCCPC score, two or more cycles of alternating therapy may have minimal to no clinical efficacy in some cases. The trial was registered with the Chinese Clinical Trial Registry as ChiCTR-TRC-13003440 and the WHO Registry Network as U1111-1146-6714.

UV spectrophotometric simultaneous determination of paracetamol and ibuprofen in combined tablets by derivative and wavelet transforms

The application of first-order derivative and wavelet transforms to UV spectra and ratio spectra was proposed for the simultaneous determination of ibuprofen and paracetamol in their combined tablets. A new hybrid approach on the combined use of first-order derivative and wavelet transforms to spectra was also discussed. In this application, DWT (sym6 and haar), CWT (mexh), and FWT were optimized to give the highest spectral recoveries. Calibration graphs in the linear concentration ranges of ibuprofen (12–32 mg/L) and paracetamol (20–40 mg/L) were obtained by measuring the amplitudes of the transformed signals. Our proposed spectrophotometric methods were statistically compared to HPLC in terms of precision and accuracy.

Paracetamol: a focus for the general pediatrician

Paracetamol (acetaminophen) is one of the most popular and widely used drugs for the treatment of pain and fever in children. This drug has multiple mechanisms of action, but its pharmacodynamic is still not well known. The central nervous system is the main site of action and it mirrors the paracetamol effect compartment. The recommended dosages and routes of administration should be different whether paracetamol is used for the treatment of pain or fever. For example, the rectal route, while being efficacious for the treatment of fever, should be avoided in pain management. Paracetamol is a safe drug, but some clinical conditions and concomitant drugs, which are frequent in clinical practice, may increase the risk of paracetamol toxicity. Therefore, it is important to optimize its administration to avoid overdoses and maximize its effect. The principal mediator of the paracetamol toxicity is the N-acetyl-p-benzo-quinone imine (NAPQI), a toxic product of the paracetamol metabolism, which could bind cysteine groups on proteins forming paracetamol-protein adduct in the liver.

CONCLUSION

Although frequently prescribed, the concept of "effect compartment concentration" and the possible co-factors that could cause toxicity at recommended doses are not familiar to all pediatricians and general practitioners. We reviewed the literature concerning paracetamol mechanisms of action, we highlighted some relevant pharmacodynamic concepts for clinical practice, and we summarized the possible risk factors for toxicity at therapeutic dosages.

Combined and alternating paracetamol and ibuprofen therapy for febrile children

BACKGROUND

Health professionals frequently recommend fever treatment regimens for children that either combine paracetamol and ibuprofen or alternate them. However, there is uncertainty about whether these regimens are better than the use of single agents, and about the adverse effect profile of combination regimens.

OBJECTIVES

To assess the effects and side effects of combining paracetamol and ibuprofen, or alternating them on consecutive treatments, compared with monotherapy for treating fever in children.

SEARCH METHODS

In September 2013, we searched Cochrane Infectious Diseases Group Specialized Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; LILACS; and International Pharmaceutical Abstracts (2009-2011).

SELECTION CRITERIA

We included randomized controlled trials comparing alternating or combined paracetamol and ibuprofen regimens with monotherapy in children with fever.

DATA COLLECTION AND ANALYSIS

One review author and two assistants independently screened the searches and applied inclusion criteria. Two authors assessed risk of bias and graded the evidence independently. We conducted separate analyses for different comparison groups (combined therapy versus monotherapy, alternating therapy versus monotherapy, combined therapy versus alternating therapy).

MAIN RESULTS

Six studies, enrolling 915 participants, are included.Compared to giving a single antipyretic alone, giving combined paracetamol and ibuprofen to febrile children can result in a lower mean temperature at one hour after treatment (MD -0.27 °Celsius, 95% CI -0.45 to -0.08, two trials, 163 participants, moderate quality evidence). If no further antipyretics are given, combined treatment probably also results in a lower mean temperature at four hours (MD -0.70 °Celsius, 95% CI -1.05 to -0.35, two trials, 196 participants, moderate quality evidence), and in fewer children remaining or becoming febrile for at least four hours after treatment (RR 0.08, 95% CI 0.02 to 0.42, two trials, 196 participants, moderate quality evidence). Only one trial assessed a measure of child discomfort (fever associated symptoms at 24 hours and 48 hours), but did not find a significant difference in this measure between the treatment regimens (one trial, 156 participants, evidence quality not graded).In practice, caregivers are often advised to initially give a single agent (paracetamol or ibuprofen), and then give a further dose of the alternative if the child's fever fails to resolve or recurs. Giving alternating treatment in this way may result in a lower mean temperature at one hour after the second dose (MD -0.60 °Celsius, 95% CI -0.94 to -0.26, two trials, 78 participants, low quality evidence), and may also result in fewer children remaining or becoming febrile for up to three hours after it is given (RR 0.25, 95% CI 0.11 to 0.55, two trials, 109 participants, low quality evidence). One trial assessed child discomfort (mean pain scores at 24, 48 and 72 hours), finding that these mean scores were lower, with alternating therapy, despite fewer doses of antipyretic being given overall (one trial, 480 participants, low quality evidence)Only one small trial compared alternating therapy with combined therapy. No statistically significant differences were seen in mean temperature, or the number of febrile children at one, four or six hours (one trial, 40 participants, very low quality evidence).There were no serious adverse events in the trials that were directly attributed to the medications used.

AUTHORS' CONCLUSIONS

There is some evidence that both alternating and combined antipyretic therapy may be more effective at reducing temperatures than monotherapy alone. However, the evidence for improvements in measures of child discomfort remains inconclusive. There is insufficient evidence to know which of combined or alternating therapy might be more beneficial.Future research needs to measure child discomfort using standardized tools, and assess the safety of combined and alternating antipyretic therapy.

Randomized controlled study of the antipyretic efficacy of oral paracetamol, intravenous paracetamol, and intramuscular diclofenac in patients presenting with fever to the emergency department

Background

Fever is a common problem in adults visiting the emergency department. Extensive studies have been done in children comparing the efficacy of various antipyretics. However, studies on the efficacy of antipyretic drugs in adults are very scarce. To the best of our knowledge, no controlled trial has been carried out comparing the antipyretic efficacy of paracetamol (oral and intravenous) and intramuscular diclofenac in adults.

Methods

In this parallel-group, open-label trial, participants aged 14–75 years presenting with fever who had a temperature of more than 38.5°C were enrolled and treated. Participants were randomly allocated to receive treatment with 1,000 mg oral paracetamol (n = 145), 1,000 mg intravenous paracetamol (n = 139), or 75 mg intramuscular diclofenac (n = 150). The primary outcome was degree of reduction in mean oral temperature at 90 minutes. The efficacy of diclofenac versus oral and intravenous paracetamol was assessed by superiority comparison. Analysis was done using intention to treat principles.

Results

After 90 minutes, all three groups showed a significant reduction in mean temperature, with intramuscular diclofenac showing the greatest reduction (−1.44 ± 0.43, 95% confidence interval [CI] −1.4 to −2.5) and oral paracetamol the least (−1.08 ± 0.51, 95% CI −0.99 to −2.2). After 120 minutes, there was a significant difference observed in the mean change from baseline temperature between the three treatment groups (P < 0.0001). Significant changes in temperature were observed in favor of intramuscular diclofenac over oral and intravenous paracetamol at each time point from 60 minutes through 120 minutes inclusive.

Conclusion

Both intramuscular diclofenac and intravenous paracetamol showed superior antipyretic activity than oral paracetamol. However, in view of its ease of administration, intramuscular diclofenac can be used as a first-choice antipyretic in febrile adults in the emergency department.

Comparison of acetaminophen and ketoprofen in febrile children: a single dose randomized clinical trial

OBJECTIVE

To compare ketoprofen with acetaminophen in febrile children in terms of proportion of achieved temperatures below 37.8°C and time of temperature reduction.

METHODS

316 patients (6 months-12 years) with fever were randomly assigned to receive a single dose of acetaminophen or ketoprofen orally. Tympanic temperature was measured at the time of antipyretic administration and at 15, 30, 60, 120,180, 240 min thereafter.

RESULTS

A higher proportion of patients in the ketoprofen group achieved a temperature below 37.8°C during the 4 h follow up (95% CI, 3.03-12.99, p < 0.001). Treatment with ketoprofen was more likely to achieve temperature below 37.8°C compared to acetaminophen with odds ratio 6.25. (95% CI, 3.03-12.99, p < 0.001). Ketoprofen was superior at temperatures ≥39°C (p < 0.001). Ketoprofen group showed significantly lower mean temperatures at times 15 min (95% CI, 0.95-3.36; P < 0.001), 30 min (95% CI, 3.87-6.59; P < 0.001), 60 min (95% CI, 6.99-10.14; P < 0.001), 120 min (95% CI, 1.66-5.49; P < 0.001), 180 min (95% CI, 0.47-5.73; p < 0.05), and 240 min (95% CI, 3.87-6.59; p < 0.05). The mean temperature reductions at times 15, 30 and 60 min were larger in ketoprofen group (p < 0.001). Ketoprofen was superior to acetaminophen for less time with fever in the first 4 h (p < 0.001).

CONCLUSIONS

It seems reasonable to use ketoprofen first in need of rapid fever reduction.

Efficacy of standard doses of Ibuprofen alone, alternating, and combined with acetaminophen for the treatment of febrile children

BACKGROUND

Many pediatricians recommend, and many parents administer, alternating or combined doses of ibuprofen and acetaminophen for fever. Limited data support this practice with standard US doses.

OBJECTIVE

This study compared the antipyretic effect of 3 different treatment regimens in children, using either ibuprofen alone, ibuprofen combined with acetaminophen, or ibuprofen followed by acetaminophen over a single 6-hour observation period.

METHODS

Febrile episodes from children aged 6 to 84 months were randomized into the 3 treatment groups: a single dose of ibuprofen at the beginning of the observation period; a single dose of ibuprofen plus a single dose of acetaminophen at the beginning of the observation period; or ibuprofen followed by acetaminophen 3 hours later. Ibuprofen was administered at 10 mg/kg; acetaminophen at 15 mg/kg. Temperatures were measured hourly for 6 hours using a temporal artery thermometer. The primary outcome was temperature difference between treatment groups. Adverse-event data were not collected in this single treatment period study.

RESULTS

Sixty febrile episodes in 46 children were assessed. The mean (SD) age of the children was 3.4 (2.2) years, and 31 (51.7%) were girls. Differences among temperature curves were significant (P < 0.001; the combined and alternating arms had significantly better antipyresis compared with the ibuprofen-alone group at hours 4 to 6 (hour 4, P < 0.005; hours 5 and 6, P < 0.001). All but one of the children in the combined and alternating groups were afebrile at hours 4, 5, and 6. In contrast, for those receiving ibuprofen alone, 30%, 40%, and 50% had temperatures >38.0 °C at hours 4, 5, and 6, respectively (hour 4, P = 0.002; hours 5 and 6, P < 0.001).

CONCLUSION

During a single 6-hour observation period for these participating children, combined and alternating doses of ibuprofen and acetaminophen provided greater antipyresis than ibuprofen alone at 4 to 6 hours. ClinicalTrials.gov identifier: NCT00267293.

Fever and antipyretic use in children

Fever in a child is one of the most common clinical symptoms managed by pediatricians and other health care providers and a frequent cause of parental concern. Many parents administer antipyretics even when there is minimal or no fever, because they are concerned that the child must maintain a "normal" temperature. Fever, however, is not the primary illness but is a physiologic mechanism that has beneficial effects in fighting infection. There is no evidence that fever itself worsens the course of an illness or that it causes long-term neurologic complications. Thus, the primary goal of treating the febrile child should be to improve the child's overall comfort rather than focus on the normalization of body temperature. When counseling the parents or caregivers of a febrile child, the general well-being of the child, the importance of monitoring activity, observing for signs of serious illness, encouraging appropriate fluid intake, and the safe storage of antipyretics should be emphasized. Current evidence suggests that there is no substantial difference in the safety and effectiveness of acetaminophen and ibuprofen in the care of a generally healthy child with fever. There is evidence that combining these 2 products is more effective than the use of a single agent alone; however, there are concerns that combined treatment may be more complicated and contribute to the unsafe use of these drugs. Pediatricians should also promote patient safety by advocating for simplified formulations, dosing instructions, and dosing devices.

Management of fever in children: summary of the Italian Pediatric Society guidelines

OBJECTIVE

This article summarizes the Italian Pediatric Society guideline on the management of the signs and symptoms of fever in children, prepared as part of the National Guideline Program (NGLP).

METHODS

Relevant publications in English and Italian were identified through searches of MEDLINE and the Cochrane Database of Systematic Reviews from their inception through December 31, 2007. Based on the consensus of a multidisciplinary expert panel, the strength of the recommendations was categorized into 5 grades (A-E) according to NGLP methodology.

SUMMARY

In the health care setting, axillary measurement of body temperature using a digital thermometer is recommended in children aged <4 weeks; for children aged > or =4 weeks, axillary measurement using a digital thermometer or tympanic measurement using an infrared thermometer is recommended. When body temperature is measured at home by parents or care-givers, axillary measurement using a digital thermometer is recommended for all children. Children who are afebrile when seen by the clinician but are reported to have had fever by their caregivers should be considered febrile. In special circumstances, high fever may be a predictive factor for severe bacterial infection. Use of physical methods of reducing fever is discouraged, except in the case of hyperthermia. Use of antipyretics-paracetamol (acetaminophen) or ibuprofen-is recommended only when fever is associated with discomfort. Combined or alternating use of antipyretics is discouraged. The dose of antipyretic should be based on the child's weight rather than age. Whenever possible, oral administration of paracetamol is preferable to rectal administration. Use of ibuprofen is not recommended in febrile children with chickenpox or dehydration. Use of ibuprofen or paracetamol is not contraindicated in febrile children with asthma. There is insufficient evidence to form any recommendations concerning fever in children with other chronic conditions, but caution is advised in cases of severe hepatic/renal failure or severe malnutrition. Newborns with fever should always be hospitalized because of the elevated risk of severe disease; paracetamol may be used, with the dose adjusted to gestational age. Use of paracetamol or ibuprofen is not effective in preventing febrile convulsion or the adverse effects of vaccines.

Alternating antipyretics: antipyretic efficacy of acetaminophen versus acetaminophen alternated with ibuprofen in children

Methods A prospective, randomized double-blind placebo control study comparing the efficacy of acetaminophen to acetaminophen alternated with ibuprofen in 38 healthy outpatient children 6 months to 6 years presenting to the outpatient clinic with fever >38 degrees C was conducted. Temperatures were recorded at 0, 3, 4, 5, and 6 hours. Side effect diaries and parental perception of efficacy were filled out hourly by parents.Results There were no significant differences in temperature between the 2 groups at times 0, 3, and 6 hours. The alternating group had significantly lower mean temperatures at both 4 hours (38.0 degrees C vs 37.4 degrees C; P = .05) and 5 hours (37.1 degrees C vs 37.9 degrees C; P = .0032). Parents did not perceive any difference in fever control between the groups.Conclusions An alternating regimen of acetaminophen with ibuprofen significantly decreased fever at 4 and 5 hours compared with acetaminophen alone. However, parents did not perceive a difference in efficacy.

Paracetamol plus ibuprofen for the treatment of fever in children (PITCH): randomised controlled trial

OBJECTIVE

To investigate whether paracetamol (acetaminophen) plus ibuprofen are superior to either drug alone for increasing time without fever and the relief of fever associated discomfort in febrile children managed at home.

DESIGN

Individually randomised, blinded, three arm trial.

SETTING

Primary care and households in England.

PARTICIPANTS

Children aged between 6 months and 6 years with axillary temperatures of at least 37.8 degrees C and up to 41.0 degrees C.

INTERVENTION

Advice on physical measures to reduce temperature and the provision of, and advice to give, paracetamol plus ibuprofen, paracetamol alone, or ibuprofen alone.

MAIN OUTCOME MEASURES

Primary outcomes were the time without fever (<37.2 degrees C) in the first four hours after the first dose was given and the proportion of children reported as being normal on the discomfort scale at 48 hours. Secondary outcomes were time to first occurrence of normal temperature (fever clearance), time without fever over 24 hours, fever associated symptoms, and adverse effects.

RESULTS

On an intention to treat basis, paracetamol plus ibuprofen were superior to paracetamol for less time with fever in the first four hours (adjusted difference 55 minutes, 95% confidence interval 33 to 77; P<0.001) and may have been as good as ibuprofen (16 minutes, -7 to 39; P=0.2). For less time with fever over 24 hours, paracetamol plus ibuprofen were superior to paracetamol (4.4 hours, 2.4 to 6.3; P<0.001) and to ibuprofen (2.5 hours, 0.6 to 4.4; P=0.008). Combined therapy cleared fever 23 minutes (2 to 45; P=0.025) faster than paracetamol alone but no faster than ibuprofen alone (-3 minutes, 18 to -24; P=0.8). No benefit was found for discomfort or other symptoms, although power was low for these outcomes. Adverse effects did not differ between groups.

CONCLUSION

Parents, nurses, pharmacists, and doctors wanting to use medicines to supplement physical measures to maximise the time that children spend without fever should use ibuprofen first and consider the relative benefits and risks of using paracetamol plus ibuprofen over 24 hours.

Over-the-counter medication use for childhood fever: a cross-sectional study of Australian parents

AIM

To report Australian parents' medication (paracetamol, ibuprofen and homeopathic) use in childhood fever management.

METHODS

A cross-sectional survey of 401 Queensland parents of children aged between 6 months and 5 years recruited through advertising (48.4%), face-to-face (26.4%) and snowball (24.4%) methods was conducted. A 17-item instrument was developed; construct and content validity were determined by an expert panel; and item reliability by test-retest with nine parents. Areas targeted were medication use and influences on and barriers to medication use.

RESULTS

Most participants were female, had tertiary education and lived in a major city (mean age 34.6 years). Reducing children's fever with over-the-counter medications was common (91%): 94% of parents reported using paracetamol and 77% reported using ibuprofen. A few (3.7%) used homeopathic remedies. Dosage was determined by weight (86.3%), age (84.3%), temperature (32.4%), illness severity (31.4%) and lethargy (20.9%). Frequency was determined by instructions on the medication label (55.3%), temperature (40.6%) and well-being (27.7%). Ibuprofen was administered too frequently by 31.5% (four hourly by 22.8%), and paracetamol by 3.8%. Fifty-two per cent had alternated medications, 65.8% of these for temperatures below 38.5 degrees C. Decisions to alternate were influenced by information from doctors/hospitals (49.5%) and children remaining febrile post-antipyretic (41.7%). Most parents reported over-the-counter medications as potentially harmful (73.2%), citing liver (38.2%), stomach (26.4%) and kidney (18.6%) damage and overdose (35.7%) as concerns. When medications were refused or spat out (44.0%), parents used force (62.4%), different methods (29.5%) or suppositories (20.8%).

CONCLUSIONS

Most parents used over-the-counter medications to reduce fever, often below 38.5 degrees C. The belief that these medications were harmful was overridden by fears of harmful outcomes from fever.
