Abstract
Background Breastfeeding is recognized as the optimal form of nutrition for the physical and neurological development of infants and is considered the most significant way to prevent child mortality. This study aimed to assess the effectiveness of metoclopramide for enhancing milk production in lactating women. Methods We searched the Cochrane Central Register of Controlled Trials and MEDLINE for randomized controlled trials comparing metoclopramide with a placebo, no treatment, or other galactagogue drugs. We included breastfeeding women with term or preterm infants. Results We retrieved 164 records from our search of the electronic databases and 20 records from other sources. Eight trials involving 342 lactating women that used metoclopramide were included in this review after assessing the eligibility criteria. The meta-analysis of these trials revealed that metoclopramide did not increase the milk volume of the intervention groups compared to that of the control groups. There was a significant increase in the serum concentrations of prolactin when the mothers were administered metoclopramide. No significant adverse events were reported. Conclusion Metoclopramide did not improve milk production in lactating women. Therefore, we do not recommend using metoclopramide to increase milk production in lactating women.

Abstract
BACKGROUND Many women express concern about their ability to produce enough milk, and insufficient milk is frequently cited as the reason for supplementation and early termination of breastfeeding. When addressing this concern, it is important first to consider the influence of maternal and neonatal health, infant suck, proper latch, and feeding frequency on milk production, and that steps be taken to correct or compensate for any contributing issues. Oral galactagogues are substances that stimulate milk production. They may be pharmacological or non-pharmacological (natural). Natural galactagogues are usually botanical or other food agents. The choice between pharmacological or natural galactagogues is often influenced by familiarity and local customs. Evidence for the possible benefits and harms of galactagogues is important for making an informed decision on their use. OBJECTIVES To assess the effect of oral galactagogues for increasing milk production in non-hospitalised breastfeeding mother-term infant pairs. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), Health Research and Development Network - Phillippines (HERDIN), Natural Products Alert (Napralert), the personal reference collection of author LM, and reference lists of retrieved studies (4 November 2019). SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs (including published abstracts) comparing oral galactagogues with placebo, no treatment, or another oral galactagogue in mothers breastfeeding healthy term infants. We also included cluster-randomised trials but excluded cross-over trials. DATA COLLECTION AND ANALYSIS We used standard Cochrane Pregnancy and Childbirth methods for data collection and analysis. Two to four review authors independently selected the studies, assessed the risk of bias, extracted data for analysis and checked accuracy. Where necessary, we contacted the study authors for clarification. MAIN RESULTS Forty-one RCTs involving 3005 mothers and 3006 infants from at least 17 countries met the inclusion criteria. Studies were conducted either in hospitals immediately postpartum or in the community. There was considerable variation in mothers, particularly in parity and whether or not they had lactation insufficiency. Infants' ages at commencement of the studies ranged from newborn to 6 months. The overall certainty of evidence was low to very low because of high risk of biases (mainly due to lack of blinding), substantial clinical and statistical heterogeneity, and imprecision of measurements. Pharmacological galactagogues Nine studies compared a pharmacological galactagogue (domperidone, metoclopramide, sulpiride, thyrotropin-releasing hormone) with placebo or no treatment. The primary outcome of proportion of mothers who continued breastfeeding at 3, 4 and 6 months was not reported. Only one study (metoclopramide) reported on the outcome of infant weight, finding little or no difference (mean difference (MD) 23.0 grams, 95% confidence interval (CI) -47.71 to 93.71; 1 study, 20 participants; low-certainty evidence). Three studies (metoclopramide, domperidone, sulpiride) reported on milk volume, finding pharmacological galactagogues may increase milk volume (MD 63.82 mL, 95% CI 25.91 to 101.72; I² = 34%; 3 studies, 151 participants; low-certainty evidence). Subgroup analysis indicates there may be increased milk volume with each drug, but with varying CIs. There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints, such as tiredness, nausea, headache and dry mouth (very low-certainty evidence). No adverse effects were reported for infants. Natural galactagogues Twenty-seven studies compared natural oral galactagogues (banana flower, fennel, fenugreek, ginger, ixbut, levant cotton, moringa, palm dates, pork knuckle, shatavari, silymarin, torbangun leaves or other natural mixtures) with placebo or no treatment. One study (Mother's Milk Tea) reported breastfeeding rates at six months with a concluding statement of "no significant difference" (no data and no measure of significance provided, 60 participants, very low-certainty evidence). Three studies (fennel, fenugreek, moringa, mixed botanical tea) reported infant weight but could not be meta-analysed due to substantial clinical and statistical heterogeneity (I2 = 60%, 275 participants, very low-certainty evidence). Subgroup analysis shows we are very uncertain whether fennel or fenugreek improves infant weight, whereas moringa and mixed botanical tea may increase infant weight compared to placebo. Thirteen studies (Bu Xue Sheng Ru, Chanbao, Cui Ru, banana flower, fenugreek, ginger, moringa, fenugreek, ginger and turmeric mix, ixbut, mixed botanical tea, Sheng Ru He Ji, silymarin, Xian Tong Ru, palm dates; 962 participants) reported on milk volume, but meta-analysis was not possible due to substantial heterogeneity (I2 = 99%). The subgroup analysis for each intervention suggested either benefit or little or no difference (very low-certainty evidence). There was limited reporting of adverse effects, none of which could be meta-analysed. Where reported, they were limited to minor complaints such as mothers with urine that smelled like maple syrup and urticaria in infants (very low-certainty evidence). Galactagogue versus galactagogue Eight studies (Chanbao; Bue Xue Sheng Ru, domperidone, moringa, fenugreek, palm dates, torbangun, moloco, Mu Er Wu You, Kun Yuan Tong Ru) compared one oral galactagogue with another. We were unable to perform meta-analysis because there was only one small study for each match-up, so we do not know if one galactagogue is better than another for any outcome. AUTHORS' CONCLUSIONS Due to extremely limited, very low certainty evidence, we do not know whether galactagogues have any effect on proportion of mothers who continued breastfeeding at 3, 4 and 6 months. There is low-certainty evidence that pharmacological galactagogues may increase milk volume. There is some evidence from subgroup analyses that natural galactagogues may benefit infant weight and milk volume in mothers with healthy, term infants, but due to substantial heterogeneity of the studies, imprecision of measurements and incomplete reporting, we are very uncertain about the magnitude of the effect. We are also uncertain if one galactagogue performs better than another. With limited data on adverse effects, we are uncertain if there are any concerning adverse effects with any particular galactagogue; those reported were minor complaints. High-quality RCTs on the efficacy and safety of galactagogues are urgently needed. A set of core outcomes to standardise infant weight and milk volume measurement is also needed, as well as a strong basis for the dose and dosage form used.

Abstract
BACKGROUND Jaundice is a common neonatal problem. This study was conducted to determine the effect of metoclopramide on neonatal bilirubin and maternal prolactin (primary outcomes) and milk volume (secondary outcome). METHODS This triple-blind, randomized, controlled, clinical trial was conducted on 112 mothers. The participants were assigned to the intervention (metoclopramide) and control groups (placebo) using block randomization. Ten-mg metoclopramide and placebo tablets were taken by the participants three times a day. The intervention began in the first 2-10 hours after childbirth and continued until the fifth day. The mothers' prolactin level was measured on the first morning after the intervention and on the sixth day (1 day after the intervention was over). Neonatal total bilirubin was also measured before the intervention and on the sixth day. RESULTS After the intervention, the two groups did not differ significantly in terms of the mean neonatal indirect bilirubin (P = 0.565) and milk volume (P = 0.261), but the mean serum prolactin was significantly higher in the metoclopramide group compared to the placebo group (adjusted mean difference 37; 95% confidence interval 58.1-16.5; P = 0.001). CONCLUSIONS Metoclopramide increased maternal serum prolactin but had no effects on neonatal jaundice. The insufficient numbers of studies on this subject mandate further research.

Abstract
Human milk, either mother’s own milk or donor human milk, is recommended as the primary source of nutrition for very preterm infants. Initiatives should be in place in neonatal units to provide support to the mother as she strives to initiate and maintain a supply of breast milk for her infant. The use of galactogogues are considered when these initiatives alone may not be successful in supporting mothers in this endeavor. Although there are non-pharmacologic compounds, this review will focus on the pharmacologic galactogogues currently available and the literature related to their use in mothers of very preterm infants.

Abstract
Galactogogues are substances used to induce, maintain, and increase milk production, both in human clinical conditions (like noninfectious agalactias and hypogalactias) and in massification of production in the animal dairy industry. This paper aims to report the state of the art on the possible mechanisms of action, effectiveness, and side effects of galactogogues, including potential uses in veterinary and human medicine. The knowledge gaps in veterinary clinical practice use of galactogogues, especially in the standardization of the lactogenic dose in some pure drugs and herbal preparations, are reviewed.

Abstract
An increasing number of women are diagnosed with cancer during pregnancy and lactation. Women are usually advised to interrupt breastfeeding during systemic anticancer treatment for fear of serious adverse effects to the nursed infant. However, the issue is poorly addressed in the literature and very few studies have evaluated the safety of breastfeeding during or after cytotoxic drugs or target agents administration. In this review we will analyze the available evidence that addresses the issue of anticancer drugs, targeted agents, antiemetics and growth-factors excretion in human milk. This could serve as a unique resource that may aid physicians in the management of breastfeeding cancer patients interested in maintaining lactation during treatment.

Abstract
OBJECTIVE To review data regarding the efficacy of galactogogues available in the US to increase breast milk production in postpartum mothers. DATA SOURCES Literature was sought using PubMed (1966-June 2012) and EMBASE (1973-June 2012). Search terms included breastfeeding, breast milk, lactation, galactogogue, metoclopramide, oxytocin, fenugreek, milk thistle, silymarin, growth hormone, thyroid releasing hormone, medroxyprogesterone, domperidone, goat's rue, beer, Asparagus racemosus, shatavari, Medicago sativa, alfalfa, Onicus benedictus, blessed thistle, Galega officinalis, brewer's yeast, and herbals. STUDY SELECTION AND DATA EXTRACTION All studies including humans and published in English with data assessing the efficacy of galactogogues for increasing breast milk production were evaluated. DATA SYNTHESIS Breast milk is considered the optimal food source for newborns through 1 year of age. Many factors influence overall maternal production, including maternal pain, illness, balance of time when returning to work, anxiety, or emotional stress. Although a variety of herbal and pharmaceutical options have anecdotal evidence of their ability to improve breast milk production, peer-reviewed studies proving their efficacy are lacking. Metoclopramide, oxytocin, fenugreek, and milk thistle have shown mixed results in improving milk production; however, the trials were small and had a variety of limitations. CONCLUSIONS Nonpharmacologic recommendations should be exhausted before adding therapy. Although anecdotal evidence encourages the use of metoclopramide, fenugreek, asparagus, and milk thistle for their galactogogue properties, efficacy and safety data in the literature are lacking. Oxytocin and domperidone are potentially available for compounding purposes, but safety data are limited. More studies are needed to evaluate the effects of available galactogogues on breast milk production.

Abstract
Use of plant and drug products to enhance lactation is widespread, and numerous papers have been published in the medical literature claiming efficacy for various products. This paper will review and evaluate the published literature on the most widely used pharmaceuticals that are used as galactagogues. Breastfeeding physiology is reviewed with the aim of creating a framework for understanding galactagogue pharmacology. Published articles were selected and evaluated using the principles of evidence-based medicine, and were also evaluated using the principles of good lactation management. Only three studies on oxytocin and seven studies on dopamine antagonists were found to be useful. Oxytocin is probably not useful as a galactagogue, except possibly in rare circumstances of tetraplegic mothers. Dopamine antagonists appear not to enhance milk supply if mothers are given good lactation support and employ these practices. The safety of the dopamine antagonists has not been adequately evaluated, so their use should be avoided unless other measures have failed.

Abstract
OBJECTIVE To investigate the effect of metoclopramide on breast milk volume and duration of breastfeeding in women delivering preterm. METHODS Women who planned to breastfeed and delivered between 23 and 34 weeks of gestation were eligible to participate in this randomized, double-blind, placebo-controlled study. Women were randomized to receive 10 mg of metoclopramide or placebo 3 times a day for 10 days, starting within 96 hours of birth. Breastfeeding education was standardized for all women. Mothers recorded the volume of breast milk expressed at each pumping for 17 days. Duration of breastfeeding was measured by monthly follow-up phone calls to each subject. RESULTS Sixty-nine women were enrolled and 57 (82%) women completed the study: 28 in the metoclopramide group and 29 in the placebo group. The 2 groups were similar in age, education, ethnicity, gestational age, and marital status. There was no significant difference between breast milk volumes in the metoclopramide and placebo groups at each of the 17 days of the study (P = .26 to .98; test for mean metoclopramide effect P = .80). There was no significant difference between groups in duration of breastfeeding, with a median of 8.8 weeks, an interquartile range of 3.4 to 12.0 weeks for the metoclopramide group and a median of 8.6 weeks, and an interquartile range of 5.6 to 16.9 weeks for the placebo group (P = .09). CONCLUSION Metoclopramide did not improve breast milk volume or duration of breastfeeding in this population of women. Regardless of therapy received, breastfeeding duration in this study of preterm mothers was poor. LEVEL OF EVIDENCE I.

Abstract
Breastfeeding provides ideal nutrition, growth hormones, and antibodies that change over time as growing infants' and children's needs change and provides these inexpensively, with no harm to the environment. Breastfed infants are healthier than other infants overall, and research indicates that the health benefits may continue on into adulthood. Increasingly, women are choosing to initiate breastfeeding in the hospital, but the attrition starts early and is dramatic. For women to meet their breastfeeding goals, physicians must not only give lip service to "breast is best" but also become knowledgeable in breastfeeding management and actively promote breastfeeding in their practices and in their communities.

Abstract
BACKGROUND AND OBJECTIVE Recent studies have shown that administration of the anterior pituitary hormone, prolactin, after hemorrhage restored the depressed immune responses that are observed under those conditions. Because metoclopramide (MCP) is known to increase prolactin secretion and ultimately plasma prolactin levels, we attempted to determine whether administration of metoclopramide after hemorrhage produces any beneficial effects on the depressed splenocyte and peritoneal macrophage immune function after severe hemorrhage. DESIGN, MATERIALS AND METHODS Mice were bled to and maintained at a mean arterial pressure of 35 mm Hg for 60 minutes, then adequately resuscitated and segregated into two groups. One group received saline vehicle; animals in the other group were treated with metoclopramide (100 microg/100 g body weight, subcutaneously) before resuscitation. Two hours after saline or MCP injection, the animals were killed and macrophage as well as splenocyte cultures established. Plasma corticosterone levels were also measured. RESULTS The proliferative capacity of the splenocytes as well as their ability to release interleukin (IL)-2 and IL-3 in response to mitogen was markedly improved in animals that had hemorrhaged and that were treated with MCP compared with saline-injected mice. Moreover, the depressed splenic and peritoneal macrophage IL-1 and IL-6 release after hemorrhage was restored with MCP treatment. Furthermore, treatment with MCP prevented the increase in blood corticosterone levels seen after severe hemorrhage. CONCLUSION These results support the concept that the immunosuppression after hemorrhage may be mediated by hormones from the hypothalamic-pituitary-adrenal axis. Furthermore, MCP may be a useful adjuvant in the treatment of the trauma-hemorrhagic shock-induced immunosuppression.

Abstract
Breastfeeding delays the resumption of normal ovarian cycles by disrupting the pattern of pulsatile release of GnRH from the hypothalamus and hence LH from the pituitary. The plasma concentrations of FSH during lactation are sufficient to induce follicle growth, but the inadequate pulsatile LH signal results in a reduced estradiol production by these follicles. When follicle growth and estradiol secretion does increase to normal, the suckling stimulus prevents the generation of a normal preovulatory LH surge and follicles either fail to rupture, or become atretic or cystic. Only when the suckling stimulus declines sufficiently to allow generation of a normal preovulatory LH surge to occur will ovulation take place with the formation of a corpus luteum of variable normality. Thus suckling delays the resumption of normal ovarian cyclicity by disrupting but not totally inhibiting, the normal pattern of release of GnRH by the hypothalamus. The mechanism of suckling-induced disruption of GnRH release remains unknown. It does not appear to involve prolactin, dopamine or opiates although a combination of these factors might be involved. Prolactin is the major hormone responsible for milk production and is present in sufficient quantities in almost all women to allow the establishment of normal lactation. Oxytocin is essential for milk let down and is susceptible to inhibition of release by stress. The successful initiation of lactation which would lead to the potential of utilizing breastfeeding as contraceptive may require more attention to be paid to the establishment of non-stress release of oxytocin.

Abstract
OBJECTIVE To study the lactational and hormonal responses to nasal administration of thyrotrophin-releasing hormone (TRH) in puerperal women with inadequate lactation. DESIGN Prospective randomized double-blind placebo-controlled study. SUBJECTS 19 puerperal women with inadequate lactation (less than 50% of normal milk yield) on the 5th day postpartum. INTERVENTIONS 10 women were allocated to receive TRH administered by a nasal spray of 1 mg, four times daily, between suckling episodes, for 10 consecutive days starting on day 6 postpartum. Nine women were allocated to receive placebo sprays. MAIN OUTCOME MEASURES Daily milk yield, serum levels of prolactin and thyroid hormones. RESULTS Before treatment all the women had significant prolactin responses to TRH and suckling stimuli. At the end of 10 days of treatment, milk yield increased significantly in the TRH group from a mean of 142.0 (SD 33.9) to 253.0 (SD 105.3) g/day (P = 0.014). There was no significant change in the placebo group. Basal prolactin levels increased from a mean of 117.4 micrograms/l (SD 45.2) to 173.3 micrograms/l (SD 55.5) (P less than 0.001) in the TRH group whereas in the placebo group prolactin levels decreased from 137.2 (SD 69.5) to 82.0 (SD 37.7) micrograms/l. A further rise in prolactin levels and milk yield was seen in seven women in the TRH group who received a second 10-day course of TRH treatment at their own request. There was no significant change in levels of thyroid stimulating hormone, thyroxine and triiodothyronine during treatment in either of the two treatment groups and no signs of hyperthyroidism. CONCLUSION Repeated nasal TRH administration between suckling episodes may improve defective lactation.

Abstract
1. The aim of this study is to review the mechanisms implicated in nausea and vomiting and the treatment of these symptoms. 2. Metoclopramide, a benzamide, is the drug most frequently used to alleviate or abolish the majority of nausea and vomiting of different origin. Domperidone, which scarcely penetrates the central nervous system (CNS), is less used. 3. The treatment of vomiting induced by cytotoxic drugs is necessary to use a combination (two or more) of antiemetic drugs (metoclopramide, glucocorticoids, antihistamines, butyrophenones, anticholinergics, cannabinoids). Recently, antagonists of serotonergic (5-HT) receptors of the subtype 5-HT3 appear to possess interesting antiemetic properties and they have a promising future in this field. 4. Antagonists of dopamine receptors (benzamides, phenotiazines, butyrophenones and domperidone) induce adverse reactions in CNS (mainly extrapyramidal disorders), which are scarce with metoclopramide and practically absent with domperidone. These disorders must not suppress antiemetic therapy when it is needed.

Abstract
The possible effect on the infant of dopamine antagonists used to promote lactation is cause for concern. Domperidone (Motilium) may be safer than other drugs in this group as it does not cross the blood-brain barrier. The mean serum level of prolactin 2 h after treatment with 20 mg of domperidone in the puerperium was 255 ng/ml compared with 150 ng/ml after a placebo. The mean domperidone level in all breast milk samples during treatment with 10 mg, three times daily, was 2.6 ng/ml. This was significantly more than levels after a single 20 mg dose sampled at 2 h (0.24 ng/ml) and at 4 h (1.1 ng/ml), and considerably less than values available for metoclopramide and sulpiride, relative to the therapeutic dosage. The effectiveness of domperidone to augment lactation requires further study.

Abstract
The purpose of this randomized, double-blind clinical study was to evaluate the efficacy of the antidopaminergic agent metoclopramide (MC) in the treatment of puerperal lactational insufficiency, and prolactin, TSH and free thyroxine responses of the mother and the child to this therapy. Therefore, 11 women received MC (10 mg 3 times daily orally) and 14 a placebo for 3 wk. MC increased the serum concentration of PRL from 57.5 + 45.5 U/l to 315.0 + 300.0 U/l (P less than 0.001), and the amount of daily milk yield in 8 women with established lactational deficiency rose from 285 + 75 ml to 530 + 162 ml (P less than 0.01) while the placebo was ineffective. Serum concentrations of TSH and free thyroxine did not change during either of the treatments. Serum concentrations of PRL, TSH and free thyroxine in the infants were similar in both groups and remained unchanged throughout the study. Our results suggest that MC is useful in the treatment of deficient puerperal lactation, and it does not stimulate the pituitary lactotropes or thyrotropes of the nursing infants.

Abstract
Since previously reviewed in the Journal (Vol. 12, No. 2), metoclopramide has been confirmed as an effective drug in treating and preventing various types of vomiting and as a useful agent in oesophageal reflux disease, gastroparesis, dyspepsia, and in a variety of functional gastrointestinal disorders. Of considerable importance is the recent evidence of its efficacy when administered intravenously in high dosages in preventing severe vomiting associated with cisplatin. Good results have been achieved in patients not previously treated with cisplatin, but further studies are needed to determine its level of efficacy in patients who have experienced severe vomiting during earlier courses of cytotoxic therapy. Side effects consisting of mild sedation, diarrhoea and reversible extrapyramidal reactions have occurred, but are tolerated by many patients.

Abstract
Thirteen primiparous nursing mothers participated in this placebo-controlled double blind trial of metoclopramide. Therapy was started on the first postpartum day and continued for 8 days. Seven women received metoclopramide (10 mg, 3 X dd). Serum prolactin and milk yield were measured during the trial. The breast milk composition was analysed during the trial and weekly for 3 wk after the trial. A detailed analysis of the amino acid content was performed on the 6th and 21st postpartum days. During the early puerperium the total milk yield was ca. 50% greater in the metoclopramide-treated group compared to the control group. The evolution of the breast milk composition was similar for both groups, except for the amino acid content. The shift in amino acid composition occurred earlier in the treatment group indicating that metoclopramide enhances the rate of transition from colostrum to mature milk.

Abstract
Domperidone is a dopamine antagonist that does not readily enter the central nervous system. Given parenterally or orally it increases gastric emptying of liquids and increases lower oesophageal sphincter pressure in healthy subjects. The antiemetic and pharmacodynamic profile of domperidone is similar to that of metoclopramide, although domperidone has a lower propensity to cause extrapyramidal side effects. Domperidone effectively alleviates symptoms of chronic postprandial dyspepsia and nausea and vomiting due to a wide variety of underlying causes and in some studies has been superior to metoclopramide. Vomiting associated with the administration of moderately emetic cytotoxic drugs is controlled in the majority of patients. Alleviation of the dose-limiting peripheral side effects (nausea and vomiting) of the anti-Parkinsonian drugs bromocriptine and levodopa, enables a higher optimum dose, with consequent improvement in Parkinsonian symptoms. Domperidone does not aggravate the extrapyramidal side effects of neuroleptic drugs. Control of cytotoxic-induced, and postprandial nausea and vomiting in children has been achieved with domperidone without evidence of extrapyramidal side effects. Indeed, side effects have seldom occurred with therapeutic doses of domperidone.

Abstract
The pharmacokinetics and endocrinological effects of metoclopramide were investigated in 5 mothers with deficient lactation and in their children soon after delivery. In addition, the transfer of metoclopramide into breast milk was evaluated in 18 mothers during the 8th to 12th puerperal weeks. Metoclopramide was detected in all the milk samples studied, generally at a higher concentration than in maternal plasma. Metoclopramide was found in plasma from only 1 of the 5 neonates studied. Exposure of the child to metoclopramide, estimated by multiplying the daily breast milk volume by the concentration of metoclopramide in the milk, ranged from 6 to 24 micrograms/kg/day for the 5 children in the early puerperium to 1 to 13 micrograms/kg/day for the 18 children during the late puerperium. These quantities are considerably less than the therapeutic dose of 500 micrograms/kg/day recommended for children. However, the plasma concentration of prolactin in 4 out of 7 neonates sampled taken during administration of metoclopramide to the mother were higher than the highest plasma prolactin level in children of same age of untreated mothers. The plasma concentration of thyrotrophin in the newborns remained within the normal range.

Abstract
In a placebo-controlled, cross-over study, thirty-seven puerperal women with inadequate production of breast-milk were treated with 5, 10, or 15 mg of metoclopramide three times a day for 2 weeks. Doses of 10 or 15 mg significantly raised maternal serum prolactin; they also increased breast-milk secretion by 42.5 +/- 34.7 (SD) ml and 50.0 + 35.9 ml per feed, respectively. This effect was unrelated to the phase of the puerperium during which treatment was started. The increase in milk secretion was associated with a decreased need for supplementary feeds, and 33% of the infants of these mothers needed no supplementary feeds during treatment. 5 mg doses did not stimulate prolactin milk secretion. Although placebo had no objective effect on the milk yield, 24% of the women judged its effect to be good, and 89% of women on metoclopramide reported a good effect. Seven women on metoclopramide and three women on the placebo complained of slight side-effects. No adverse effects upon the infants were observed. Metoclopramide therapy may be useful for improving poor lactation.
