What is Rebamipide and How Does It Work?
Rebamipide is a medication primarily prescribed to protect the gastric mucosa and promote the healing of stomach ulcers and lesions. It works as a cytoprotective agent by increasing prostaglandin synthesis, enhancing mucus secretion, promoting tissue repair, and scavenging free radicals.
The Critical Lack of Human Safety Data
Despite its benefits for gastric issues, the safety of rebamipide for pregnant women is largely unconfirmed due to a lack of controlled human studies. While it was previously classified under the FDA Pregnancy Category C, the current system emphasizes a detailed risk summary. The consensus is to use rebamipide during pregnancy only if the potential benefits clearly outweigh potential risks, under strict medical supervision.
Findings from Animal Studies
Animal studies, such as those in rats, have not shown toxic effects on reproductive outcomes or fetal development with rebamipide. However, these findings cannot be directly applied to humans, highlighting the need for human-specific safety data.
Safer Alternatives for Pregnant Women with Gastric Issues
For pregnant women experiencing gastrointestinal discomfort, a stepwise approach with established safe therapies is recommended. This includes lifestyle and dietary modifications, antacids (such as calcium-containing and magnesium-based options), sucralfate, and H2-receptor antagonists (like famotidine). Proton pump inhibitors (PPIs) are generally reserved for severe symptoms, with caution advised. A comparison of rebamipide and some of these alternatives regarding mechanism, safety in pregnancy, and clinical data shows that while rebamipide's safety in humans is not established and it is generally avoided, alternatives like antacids, sucralfate, and H2RAs are generally considered safe with extensive data.

Conclusion
The safety of rebamipide in human pregnancy is not established due to a lack of data, leading to a general recommendation against its use for expectant mothers. While animal studies didn't show risk, these aren't conclusive for humans. Safer alternatives with proven safety profiles, such as lifestyle changes, antacids, sucralfate, or H2RAs, are the preferred treatment for pregnant women with gastrointestinal issues. Any medication decisions during pregnancy must be made after consulting a healthcare provider to assess individual risks and benefits.
When to Consult Your Healthcare Provider
It is crucial to consult your healthcare provider before taking any medication while pregnant to ensure the safest treatment for you and your baby. Seek immediate medical attention for severe symptoms like persistent vomiting or unexplained abdominal pain.
