Colds are common during pregnancy. Since pregnancy affects your immune system, your symptoms might last longer than they would otherwise. If you need drugs to relieve the symptoms, take them only on a short-term basis and follow the recommendations of Pharmacist’s Letter/Prescriber’s Letter to select a drug that had been on the market long enough for the accumulation of data about its effects on the baby. Do not select a new drug. Testing for drug safety does not include pregnant women, since there might be risks to the baby. Before taking any medication, especially during the first trimester, discuss the risks and benefits with your doctor.

Alternatives to Drugs
The University of Michigan Health System recommends taking no medication during the first trimester or after 38 weeks unless your doctor recommends it. To relieve your symptoms, you can try resting more and drinking more fluids. If you are having problems eating, you can try eating six small meals instead of three larger ones. For sinus pain, you can apply warm compresses. To loosen congestion, you can use a vaporizer or humidifier. If you still have no relief, ask your doctor to recommend a safe medication.
