Over-the-Counter Medications in Pregnancy

Area of Science:

• Pharmacology
• Obstetrics
• Public Health

Background:

• Many pregnant women use over-the-counter (OTC) medications without robust evidence from randomized controlled trials.
• Existing data primarily derive from observational studies, necessitating a clearer understanding of medication safety during pregnancy.

Purpose of the Study:

• To review the safety profile of commonly used OTC medications during pregnancy.
• To identify medications with established safety data and those requiring further investigation.

Main Methods:

• Review of existing literature and data on OTC medication use in pregnancy.
• Analysis of safety information for various drug classes, including analgesics, cold, gastrointestinal, and herbal medications.

Main Results:

• Acetaminophen is widely used and generally considered safe across all trimespi. Cold medications are safe for short-term use after the first trimester. Gastrointestinal medications like H2 blockers and PPIs show no significant fetal effects.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) are not recommended, particularly during organogenesis and the third trimester. Ginger is safe for nausea, and topical creams are generally considered safe.
• Limited data exist for many herbal supplements, underscoring the need for caution.

Conclusions:

• OTC medication use during pregnancy requires careful consideration of risks and benefits for each medication and symptom.
• Formalized studies are crucial to support informed decision-making for pregnant individuals regarding OTC medication safety.
