GUIDE
Some OTC medications are safe during pregnancy, others should be avoided. This guide is your quick-reference list — but always confirm with your provider.
Medication safety during pregnancy depends on the drug, the dose, the trimester, and your individual health. No guide replaces a conversation with your provider, but this reference will help you understand the general safety landscape and know what to ask about.
Be prepared from day one
This guide is a reference tool, not a substitute for medical advice. Medication safety during pregnancy is nuanced — it depends on the specific drug, the dose, the timing, your health conditions, and other medications you are taking. Always confirm with your provider before starting or stopping any medication.
The categories below are based on current ACOG, FDA, and CDC guidance. "Generally safe" means the medication has a long track record of use in pregnancy with no known increased risk. "Avoid" means there is evidence of potential harm. "Caution" means the safety data is limited or the medication may be acceptable in certain situations under provider guidance.

Many OTC products contain multiple active ingredients. A single NyQuil capsule contains acetaminophen, dextromethorphan, and doxylamine. An Excedrin tablet contains acetaminophen, aspirin, and caffeine. Always read the Drug Facts panel and check each ingredient individually against this guide.
Contact your provider before taking any medication if you are in the first trimester (when organ development is most sensitive), have a high-risk pregnancy, are taking prescription medications that could interact, have liver or kidney conditions, or are unsure about any ingredient.
