Consumer preferences for over-the-counter drug retailers in the reregulated Swedish pharmacy market

Characteristics of the drinking habits of people who overdose over-the-counter drugs: Insights from a nationwide Japanese survey

Aim

To analyze the drinking habits of individuals who overdosed on over-the-counter (OTC) drugs, such as cough suppressants, antitussives, antipyretic analgesics, and combination cold medications, in Japan.

Methods

This cross-sectional study analyzed data collected from 2881 participants through a national survey conducted in Japan in 2023. Through a self-administered questionnaire, the participants were categorized into OTC (overdosed OTC drugs in the past year) and control (did not overdose OTC drugs) groups. Variables related to drinking habits, social background, smoking habits, use of other medications, such as analgesics, tranquilizers, controlled drugs, and products containing high concentrations of caffeine, and perception of OTC drugs were compared between the two groups. Additionally, we matched the participants in the OTC (n = 25) and control (n = 100) groups by sex and age in a 1:4 ratio to assess these variables. Multivariate analyses were performed to examine how these factors are associated with drinking habits in individuals with OTC drug overdose.

Results

OTC drug overdose was prevalent among teenagers and those in their 50s, and was associated with habitual binge drinking and consumption of energy drinks. Those overdosing on OTC drugs obtained them mostly from drugstores and pharmacies.

Conclusion

This is the first study to show a relationship between drinking habits and OTC drug overdose. An understanding of the characteristics of drinking habits in those who overdose on OTC drugs can help reduce fatal health risks in this population.

Analysis of Japanese consumers' attitudes toward the digital transformation of OTC medicine purchase behavior and eHealth literacy: an online survey for digital experience design

Introduction

Since the enactment of the revised Pharmaceutical Affairs Act in Japan in 2009, self-medication practices have increased in the country. However, studies report that consumers pay little attention to the medication facts and risks indicated on the packages of over-the-counter (OTC) medicines, which could be a potential risk. Since the COVID-19 pandemic, the digital transformation of purchasing OTC medicines has progressed. As an appropriate design for the digital transformation is likely to improve consumers' literacy and them obtaining medical information, this study systematically examines Japanese consumers' attitudes toward the digital transformation of OTC medicine purchase behavior and its correlation to eHealth literacy, exploring an appropriate digital experience design in purchasing OTC medicine.

Methods

Participants from the Greater Tokyo Area of Japan participated in an online survey. Consumers' current behavior and preferences in accessing OTC medicine, receiving medication guidance, and obtaining medical information were examined. eHealth literacy was assessed using the J-eHEALS. Descriptive statistics, text mining, and thematic analysis were conducted to answer research questions.

Results

Over 89% of the respondents who had experience in purchasing OTC medicines preferred local pharmacies or stores rather than online purchasing, p < 0.001. Obtaining medicine guidance in pharmacies or stores was the main preference over other approaches, p < 0.001. Furthermore, most of the participants accepted selecting medicine on shelves and digital screens in-store. However, they were accustomed to using smartphones to obtain additional information at the pharmacy or drug store, p < 0.001; this behavior was positively correlated with eHealth literacy, p < 0.001.

Conclusions

Japanese consumers are seeking a combination of conventional and digital behaviors for purchasing OTC medicine rather than opting for a particular method. Most consumers prefer purchasing and receiving instructions in-store while searching for additional decision-making information online. eHealth literacy is positively associated with digital behaviors of OTC medicine information acquisition but less associated with medicine purchases and selections. The hybrid digital experience design may enhance the OTC medicine purchase experience and reduce potential risks by providing appropriate information.

Prevalence and influencing factors of self-medication during the COVID-19 pandemic in the Arab region: a multinational cross-sectional study

BACKGROUND

The novel coronavirus pandemic (COVID-19) has begun with a wave of misinformation and fear of infection. This may have led people to self-medicate inappropriately. The World Health Organization describes self-medication (SM) as utilizing medicines to relieve symptoms or health conditions without consulting a physician. Inappropriate drug use is a burden on both health resources and patient health in the Arab region. This study aimed to detect the prevalence and influencing factors of self-medication among the general Arab population during the COVID-19 pandemic.

METHODS

A multinational cross-sectional study was conducted among the general population of ten Arab countries from early August to late October 2021. Participants aged 18 years or older could join the study via social media platforms. A convenience sampling technique was used. A developed and validated web-based questionnaire was used to collect data on self-medication practice, associated influencing factors, information sources, commonly used medications, and commonly treated conditions. Descriptive, univariate, and multivariate regression analyses were applied using IBM SPSS v 26 and R v 4.0.0 software.

RESULTS

A total of 8163 participants completed the questionnaire, and 518 participants were excluded from the analysis due to inconsistencies in their data. Almost two-thirds (62.7%) of participants reported practicing self-medication during the COVID-19 pandemic. At the country level, Egypt had the highest prevalence of self-medication practice (72.1%), while Palestine had the lowest prevalence (40.4%). The most commonly used drugs were analgesics, antipyretics, and vitamins (86, 65.1, and 57.1%, respectively), while antitussives and antibiotics scored 47.6 and 43.3%, respectively. Experience with similar health conditions (74.6%) and urgency of the problem (47.2%) were the most frequent factors that led to self-medication. Additionally, 38.2% of the self-medicated participants (SMPs) used drugs as prophylaxis against COVID-19. Pharmacist consultation was the most common source of information about self-medication (66.7%). Multivariate analysis showed that predictors of self-medication were older age (p = 0.008), presence of chronic illness (p = 0.015), and having monthly income or medical insurance that does not cover the treatment cost (p = 0.001, p < 0.001, respectively).

CONCLUSION

Self-medication is considered a common practice across the Arab population. It is necessary to regulate policies and raise awareness among the public about self-medication.

Use of Nonsteroidal Anti-Inflammatory Drugs and Risk of Breast Cancer: Evidence from a General Female Population and a Mammographic Screening Cohort in Sweden

A link has been proposed between the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and the risk of breast cancer. There is, however, insufficient data regarding the subtype and stage of breast cancer, and few studies have assessed the interaction between the use of NSAIDs and breast density or previous breast disorders. There is also a lack of data from population-based studies. We first conducted a nested case-control study within the general female population of Sweden, including 56,480 women with newly diagnosed breast cancer during 2006-2015 and five breast cancer-free women per case as controls, to assess the association of NSAID use with the risk of incident breast cancer, focusing on subtype and stage of breast cancer as well as the interaction between NSAID use and previous breast disorders. We then used the Karolinska Mammography Project for Risk Prediction of Breast Cancer (Karma) cohort to assess the interaction between NSAID use and breast density in relation to the risk of breast cancer. Conditional logistic regression was used to estimate the hazard ratio (HR) and a 95% confidence interval (CI) was used for breast cancer in relation to the use of aspirin and non-aspirin NSAIDs. In the nested case-control study of the general population, exclusive use of aspirin was not associated with the risk of breast cancer, whereas exclusive use of non-aspirin NSAIDs was associated with a modestly higher risk of stage 0-2 breast cancer (HR: 1.05; 95% CI: 1.02-1.08) but a lower risk of stage 3-4 breast cancer (HR 0.80; 95% CI: 0.73-0.88). There was also a statistically significant interaction between the exclusive use of NSAIDs and previous breast disorders (p for interaction: <0.001). In the analysis of Karma participants, the exclusive use of non-aspirin NSAIDs was associated with a lower risk of breast cancer among women with a breast dense area of >40 cm² (HR: 0.72; 95% CI: 0.59-0.89). However, the possibility of finding this by chance cannot be ruled out. Overall, we did not find strong evidence to support an association between the use of NSAIDs and the risk of breast cancer.

Prevalence and associated risk factors of self-medication with over-the-counter medicines among university students in the United Arab Emirates

Background

Proper self-medication with Over the Counter (OTC) medicines can benefit both the patient and the healthcare sector. Although OTC medications are considered relatively safe, their improper use can lead to serious health risks and implications. This study investigates the self-medication practices with OTC medicines among medical and non-medical students at different universities in the United Arab Emirates.

Methods

A cross-sectional study was carried out over six months (January-June 2021). The desired confidence level was set at 95%, and the precision level was 0.03. A three-step cluster sample method was employed. A self-administered questionnaire that assessed predisposing, enabling and need factors associated with the use of OTC medicines was developed based on Andersen's behavioural model.

Results

A total of 2355 students completed the study questionnaire. The mean age was 20.94, and 76.3% were female. More than half of the participating students (57.5%) reported using OTC medicines during the past 90 days of conducting the study. A good proportion (67.8%) reported performing a high level of self-care. Student's perceived health (p<0.0001), educational background (p=0.003), use of left-over drugs (p=0.002), relies on informal sources for drug information (p=0.0001) and reading drugs information leaflets (p<0.0001) were all significantly associated with whether students sought medical advice or not.

Conclusion

Many university students were observed that they never sought pharmacist advice when taking OTC medications. The likelihood of consulting a pharmacist when using an OTC medication was lower among medical students than non-medical students and among those who do not read the drug information leaflets. The proactive role that a pharmacist can play can have paramount importance in promoting the proper and safe use of OTC drugs.

Increased use of analgesics in midlife women but no association with mental stress: observations from the Prospective Population Study of Women in Gothenburg

Background

The study is part of the ongoing Prospective Population Study of Women in Gothenburg, Sweden, initiated in 1968–1969 with the aim of characterising a total population of women who were representative of middle-aged females. The aim of the present study was to investigate the prevalence of actual analgesic use (prescribed and self-medication) and the possible association with perceived mental stress among women aged 38 and 50 years, respectively, in the Population Study of Women.

Methods

Two different cohorts of population-based samples of 38- and 50-year-old women examined in 2004–2005 and 2016–2017, respectively, were eligible participants. The women were representative for their age cohort at the time of the examinations. Use of medicines and especially analgesics, as well as perceived mental stress, was registered. Changes in medicine use among 38- and 50-year-old women between 2004 and 2005 and 38- and 50-year-old women in 2016–2017 were studied. Data were analysed using logistic regression. Use of analgesics and mental stress were analysed controlling for lifestyle factors, use of other medicines and pain.

Results

The overall sample size across the time periods was 1,073 individuals. The frequency of analgesic use in 38- and 50-year-old women was about 26% in 2004–2005 and 58% in 2016–2017. 28% of women who reported high mental stress in 2004–2005 used analgesics, compared to 60% in 2016–2017. There were no associations between self-perceived mental stress and the use of analgesics.

Conclusion

The higher use of analgesics among midlife women in 2016–2017 is in line with global findings and could be due to increased availability in Sweden of over the counter medicines. The impact of mental stress on analgesic use found previously by other researchers was not confirmed. However, medicine use as a potential coping strategy is an important public health issue that needs to be further explored.

Community Attitudes and Habits Toward Over-The-Counter Drugs: Results of a Study Conducted in Thessaloniki, Greece

OBJECTIVES

To determine the frequency of use, sources of information, and selection criteria of Greek residents regarding over-the-counter (OTC) drugs, as well as their opinion about their dispensing in nonpharmacy settings.

METHODS

This was a survey study in which an anonymous cross-sectional questionnaire was used to assess the knowledge, habits, and attitudes about OTC drugs. Data were collected from March 2017 to July 2017 in Thessaloniki, the second largest city in Greece. Logistic regression was used to investigate significant factors that affect the participants' behavior.

RESULTS

A total of 782 participants completed the questionnaire. The population had a mean (SD) age of 46 (17) years and 55.1% were females. About one-third (32.5%) of the participants used nonsteroidal anti-inflammatory drugs more than once per week. OTC drugs acting on the gastrointestinal tract were used to a lower extent (13.2%). The majority (84%) of the respondents consult a healthcare professional about the information on OTC drugs. Furthermore, when not sure about which OTC drug to use, 510 participants (65.6%) valued their physician's advice, whereas 480 participants (60.2%) valued their pharmacist's advice. Most participants (61.2%) were negatively inclined toward the purchase of OTC drugs in nonpharmacy settings, with younger participants being more receptive to out-of-pharmacy OTC drug purchase than older ones (odds ratio 2.20; 95% confidence interval 1.37-3.54).

CONCLUSIONS

Healthcare professionals play an important role in providing people information on their selection of OTC drugs. This could be the main reason why participants prefer to buy OTC drugs from community pharmacies rather than retail shops.

Self-Medication With Over-the-counter Medicines Among the Working Age Population in Metropolitan Areas of Thailand

Background and Objectives: Self-medication with over-the-counter (OTC) medicines is becoming an increasingly popular practice around the world. The global prevalence rate of self-medication ranges from 11.2% to 93.7%, depending on the target population and country. However, there is a lack of data on the prevalence and practices of self-medication among the working-age population, particularly in Thailand metropolitan areas. The current study describes the prevalence of self-medication practices, adverse drug reactions and severity, reasons for self-medication, and basic medication knowledge among people of working age in metropolitan areas in Thailand.

Methods: We conducted an online cross-sectional study between December 2020 and January 2021. Descriptive statistics were used to analyze self-medication data. A chi-square test was used to assess the association between self-medication and sociodemographic characteristics.

Results: This study found high prevalence of self-medication among the working-age population in metropolitan areas of Thailand (88.2%). The most commonly used drug groups were NSAIDs (34.8%) and antibiotics (30.2%). Minor illness and easy access to pharmacies were the most common reasons for self-medication. Almost half of the participants&apos; illnesses (42.6%) for which they self-medicated were not always completely cured, necessitating treatment at a hospital or clinic. Although only a small number of participants (ranged from 0.6 to 6.6%) experienced adverse drug reactions as a result of self-medication, some had severe symptoms that disrupted their daily lives or required hospitalization. In terms of basic medication knowledge, we discovered that study participants misunderstood some antibiotic drug concepts.

Conclusions: According to the study findings, it is recommended that more information about the risks of self-medication, drug adverse reactions, antibiotic stewardship, more supervision of the prohibition of over-the-counter drugs and selling practices, and adequate facilities for peoples access to medical services be provided at the policy level.

Intra-Individual Variability in Self-Reported Use of Non-Steroidal Anti-Inflammatory and Analgesic Medicines Depending on Mode of Data Collection - Observations from the Population Study of Women in Gothenburg, Sweden

Background

Self-report by questionnaire is one of the main methods to collect data on drug utilization. There are several modes of data collection by questionnaire, differing in the way of delivering the questionnaire to respondents and in the administration of the questions, both influencing the recall and participation rates. The aim of this study was to compare different modes of data collection for self-reported use of non-steroidal anti-inflammatory (NSAIDs) and analgesic medicines.

Methods

Data on 573 women (38 or 50 years) were retrieved from the Population Study of Women in Gothenburg. Data on medicine use were collected using two different modes: (1) a self-administered questionnaire with closed-ended medicine-specific questions; and (2) an interviewer-administered questionnaire with open-ended questions. Cohen’s kappa statistics were applied to assess the agreement of the two modes.

Results

The proportion of participants that reported use of NSAIDs and analgesics was higher with the self-administered questionnaire compared with the interviewer-administered questionnaire (69.3% vs 58.5%, p <0.001). The overall agreement between the two modes of data collection was fair (Ⱪ=0.27), ranging from none for antimigraine preparations to fair (Ⱪ=0.36) for NSAIDs. A higher proportion of the participants aged 38 years reported use of NSAIDs and analgesics compared with the 50-year olds. In the regression model using data from the self-administered questionnaire, all four categories of bodily pain were significant predictors for use of NSAIDs and analgesics. The most severe reported bodily pain was the only significant predictor in the model using data from the interviewer-administered questionnaire.

Conclusion

This study showed that use of a self-administered questionnaire with closed-ended medicine-specific questions identified more users of NSAIDs and analgesic medicines compared with an interviewer-administered questionnaire with open-ended questions. Reported use according to the self-administered questionnaire was also more strongly associated with experienced pain.

Access to Medicines via Non-Pharmacy Outlets in European Countries-A Review of Regulations and the Influence on the Self-Medication Phenomenon

Non-pharmacy trade concerns the sale of medicinal products outside of pharmacies, such as limited-service pharmacies, supermarkets, petrol stations, shops open to the public, and kiosks. Access to medicinal products via non-pharmacy outlets varies across the European countries, with a general deregulation of this market area observable. Increasing the availability of medicines by allowing patients to obtain them outside of pharmacies contributes to the spread of self-medication. The aim of this article was to review the legal regulations enabling the non-pharmacy trade in OTC (over the counter) medicinal products in European countries, with particular emphasis on the analysis of active substances contained in medicines available in the non-pharmacy trade. This analysis has made it possible to distinguish three categories of countries: (1) where there is a non-pharmacy trade in OTC medicinal products, (2) where there is a limited non-pharmacy trade in OTC medicines, (3) where there is only a pharmacy trade in OTC medicinal products. In the context of these considerations, we highlight the impact of patient access to medicinal products via non-pharmacy sources on raising the prevalence of self-medication. This article identifies the advantages and risks of self-medication, emphasising the role of the pharmacist as an advisor to patients within the scope of the therapies used.

Generic versus brand-name over-the-counter analgesics: knowledge and attitudes among Swedish pharmacy customers

Background

Due to a liberalisation reform in 2009, the availability of over-the-counter (OTC) analgesics has increased significantly in the Swedish market over the past decade. With the increasing number of generic products available on the market and the possibility of buying OTC drugs from non-pharmacy outlets, a key to safe drug use is that consumers possess the necessary knowledge to differentiate between the different brands and choose the appropriate drug for their ailments. The aim of this study was to investigate Swedish consumers' knowledge of and attitudes towards generic OTC analgesics.

Methods

A sample of 209 Swedish adults (66% women; mean age 43.1 years) who bought OTC analgesics at a community pharmacy in one of the country's three largest cities responded to a structured questionnaire. The questions related to knowledge of active substances, the use and choice of OTC analgesics (generic or original brand), attitudes towards generic OTC analgesics, information received about OTC analgesics and experience with generic substitution of prescription drugs.

Results

Almost one in five reported weekly use of OTC analgesics, and 32% assigned minimum three out of four active substances to the correct brand(s) of OTC analgesics. Among the 50 participants (24%) who assigned all four active substances correctly, it was predominantly women and participants with higher education. Four out of five participants were positive towards the cheaper brands, and 69% reportedly chose cheaper generic brands over more expensive brands. Knowledge about the active substances of different brands was associated with positive attitudes towards generic products.

Conclusion

Swedish pharmacy customers have to a varying extent the knowledge to differentiate between different brands of commonly used OTC analgesics in terms of active substances. There is a predominantly positive attitude towards generic OTC analgesics, although some consider generic drugs to be inferior and stay loyal to the original brands.

Attitudes towards sales and use of over-the-counter drugs in Sweden in a reregulated pharmacy market: a population-based study

OBJECTIVES

To analyse attitudes towards sales and use of over-the-counter (OTC) drugs in the Swedish adult population.

METHODS

Data were collected through the web-based Citizen Panel comprising 21 000 Swedes. A stratified sample of 4058 participants was emailed a survey invitation. Questions concerned use of OTC drugs, and attitudes towards sales and use of OTC drugs. Correlations between the attitudinal statements were assessed using Spearman's rank correlation. Associations between attitudes and participant characteristics were analysed using multinomial logistic regression.

KEY FINDINGS

Participation rate was 64%. Altogether 87% reported use of OTC drugs in the last 6 months. Approximately 10% of participants stated that they used OTC drugs at the first sign of illness, and 9% stated that they used more OTC drugs compared with previously, due to increased availability. The statement on use of OTC drugs at first sign of illness correlated with the statement about using more OTC drugs with increased availability. Socio-demographic factors (age, sex and education) and frequent use of OTC drugs were associated with attitudes to sales and use of OTC drugs.

CONCLUSIONS

Increased use due to greater availability, in combination with OTC drug use at first sign of illness illustrates the need for continuous education of the population about self-care with OTC drugs. Increased awareness of the incautious views on OTC drugs in part of the population is important. Swedish policy-makers may use such knowledge in their continuous evaluation of the 2009 pharmacy reform to review the impact of sales of OTC drugs in retail outlets on patient safety and public health. Pharmacy and healthcare staff could be more proactive in asking customers and patients about their use of OTC drugs and offering them advice.

A population-based study of risk perceptions of paracetamol use among Swedes-with a special focus on young adults

PURPOSE

The purpose of this study was to investigate risk perceptions of paracetamol use, with a special focus on young adults.

METHODS

A web survey was sent to a representative sample (n = 5838) of the Swedish adult population. Altogether, 3120 persons answered the full questionnaire. Risk perceptions of paracetamol use in relation to sex, age, and education were determined using logistic regression.

RESULTS

Most respondents (70.5%) reported use of paracetamol in the 3 months prior to the study; the highest proportion was found among those aged 18 to 25 years (75.8%). Nine in 10 were over-the-counter (OTC) paracetamol users. A total of 14.2% thought paracetamol is completely harmless to use while 54.3% indicated risks associated with use even when following the dosing instructions. One third disagreed that it is less risky to use paracetamol compared with nonsteroidal antiinflammatory drugs. Three-quarters identified liver damage as a potential consequence of exceeding the recommended maximum daily dose. The likelihood of a high-risk perception was higher in women compared with men, and increased with age. No association was found between risk perception and educational status. Participants aged 18 to 25 years had the same ability to identify risks of overdose as did those aged 26 to 65, but expressed more careless attitudes towards use.

CONCLUSIONS

Although the study population purchased paracetamol primarily OTC, they demonstrated basic awareness of paracetamol use including the potential consequences of overdosing. Young adults (18-25 y), who were the most frequent users of OTC paracetamol, perceived less risk associated with use compared with older participants.

Consumer views on safety of over-the-counter drugs, preferred retailers and information sources in Sweden: after re-regulation of the pharmacy market

BACKGROUND

The availability of over-the-counter drugs (OTCs) has increased in Sweden since a re-regulation of the pharmacy market in 2009, through which non-pharmacy retailers became permitted to provide certain OTCs.

OBJECTIVE

To examine the adult general public's views on safety, purchasing and information channels, storage and disposal of OTCs in Sweden, three years after the re-regulation of the pharmacy market.

METHODS

A questionnaire study in 2012-13 in a stratified, random sample of all inhabitants in Sweden ≥ 18 years old.

RESULTS

Totally 8,302 people (42%) answered the questionnaire. Seven percent found OTCs completely harmless regardless of how they are being used, 18% felt they should be used only on health professionals' recommendation. Differences in how OTCs are perceived were however found with regards to respondents' country of birth, family type, educational level and income. The pharmacy was still the preferred OTC drug retailer by 83% of the respondents and preferred information source by 80% Reasons for preferred retailers were primarily due to out of habit (45%), counseling provided (35%), the product range (34%) and the confidence in staff (27%). Analgesics are the most common OTCs to have at home (90%). The bathroom cabinet is the primary site for storage (42%) and 16% throw their OTC leftovers in the trash.

CONCLUSIONS

The study population does not consider OTCs as harmless regardless of how they are used, but on the other hand feels they should not be taken on health professionals' recommendation only. The pharmacy is still the preferred retailer and information source, and there is room for further improvement in the storage and disposal of OTCs. A return of OTC drug leftovers to the pharmacy should be further encouraged. Due to several limitations, great caution should however be observed when generalizing the results to the adult population of Sweden.

Purchase habits, use of paracetamol, and information sources on a reregulated Swedish pharmacy market: A population-based study

Considering the general lack of knowledge on how over-the-counter paracetamol is used combined with the reported increase in paracetamol poisonings after the reregulation of the Swedish pharmacy market in 2009, we aimed to analyze purchase habits and use of paracetamol in Sweden. A further aim was to investigate sources of information about paracetamol. Data were collected in October 2015 through the Citizen Panel, a Web-based panel encompassing over 50,000 Swedes. A stratified sample of 6000 (aged 18 years and older) was emailed a survey invitation. Questions concerned paracetamol use, purchase habits and information sources. The participation rate was 58%. A majority (70.5%) reported use of paracetamol during the last three months. Purchasing paracetamol solely over-the-counter was most common (81.1%). Close to two-thirds usually purchased paracetamol at a pharmacy. However, it was more common to purchase OTC paracetamol at non-pharmacy outlets among younger compared to older respondents. The results of this study did not reveal any harmful paracetamol use. The most common information source overall was patient information leaflets, and it was significantly more common among the youngest compared to older subjects. Based on our results combined with previous research, we suggest more studies, both qualitative and quantitative, among young adults, both on the use of paracetamol and on the understanding of information in patient information leaflets and on the Internet.
