Ranitidine Pregnancy Warnings
Use is recommended only if clearly needed and the benefit outweighs the risk. AU TGA pregnancy category: B1 US FDA pregnancy category: B
Animal models have failed to reveal evidence of impaired fertility or fetal harm. It is unknown whether use of gastric-suppressing drugs are associated with childhood allergy and asthma. There are no controlled data in human pregnancy. AU TGA pregnancy category B1: Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed. Studies in animals have not shown evidence of an increased occurrence of fetal damage. US FDA pregnancy category B: Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.
Ranitidine Breastfeeding Warnings
This drug is known to increase prolactin levels. There are no data on galactorrhea and/or adverse effects with breastfeeding.
Caution is recommended. Excreted into human milk: Yes
Ranitidine Levels and Effects while Breastfeeding
Summary of Use during Lactation
Although interpatient variability exists, the dose of ranitidine in breastmilk is less than the dose used in newborn infants. Maternal ranitidine would not be expected to cause any adverse effects in breastfed infants. No special precautions are required.
Maternal Levels. Six women with established lactation who were 6 to 10 days postpartum were given a single dose of 150 mg of ranitidine orally. Average milk levels were 1.28, 1.42 and 1.02 mg/L at 2, 4 and 8 hours, respectively, after the dose; however, there was great interpatient variability in both peak levels and the time of the peak.
After 5 oral doses of ranitidine 150 mg every 12 hours in a 54-day postpartum woman, the highest measured milk level occurred 5.5 hours after the 5th dose and was 2.6 mg/L. The estimated half-life in milk was 2.9 hours.
Using the average peak milk level data from these 2 papers, an exclusively breastfed infant would receive an estimated maximum of 300 mcg/kg daily with a maternal dosage of 150 mg daily. This dosage is 20% of the dosage used intravenously in newborn infants for stress ulcer prophylaxis.
Infant Levels. Relevant published information was not found as of the revision date.
Effects in Breastfed Infants
One 54-day-old breastfed infant had no observable adverse effects after maternal ingestion of ranitidine 150 mg every 12 hours for 2 days.
Effects on Lactation and Breastmilk
Histamine H2-receptor blockade is known to stimulate prolactin secretion. Ranitidine in intravenous doses over 100 mg or during long-term oral use have increased serum prolactin in some studies, but no reports of galactorrhea or effects on breastfeeding women were found as of the revision date. The prolactin level in a mother with established lactation may not affect her ability to breastfeed.
