Question

Accepted Answer

Pseudoephedrine (the active ingredient in regular Sudafed) is one of the few over-the-counter cold medicines with a specific pregnancy caution: ACOG does not recommend it in the first 3 months of pregnancy, per MotherToBaby's summary, because of a possible small increase in certain abdominal-wall birth defects with early use. After the first trimester, many OBs allow occasional short-term use, but that is a call your own provider should make, because pseudoephedrine also constricts blood vessels, raises blood pressure, and can reduce blood flow to the placenta, so anyone with high blood pressure, preeclampsia risk, or placental concerns gets a firmer no. Two practical traps: "Sudafed" on the shelf is often Sudafed PE, which is phenylephrine, a different decongestant with its own thin evidence base and the same first-trimester-caution logic; and combination cold products (Sudafed plus antihistamine, or multi-symptom formulas) bundle ingredients you may not want, so read the active-ingredient list, not the brand name. The safer congestion toolkit in pregnancy: saline nasal spray or rinse, a humidifier, honey and warm fluids (pasteurized), rest, and elevating your head at night; acetaminophen covers the headache or fever piece. If congestion is brutal and persistent, ask your OB directly; there are situations where they will green-light pseudoephedrine after week 12, and situations (rhinitis of pregnancy, allergies) where they would rather switch you to a pregnancy-compatible antihistamine or nasal steroid spray instead.
