During pregnancy, it is generally safe to take cough drops made with honey or mint. If you are not taking any other medications and do not have allergies, a cough syrup with dextromethorphan can also be used to relieve a mild cough. For a wet cough, you can try a product like Benylin Mucus Relief. For a dry cough, consider a product like Benylin Dry Cough. It is recommended to take 2 teaspoons (10 ml) every 6 to 8 hours as needed, up to a maximum of 8 teaspoons (40 ml) per day. Be cautious as dextromethorphan can cause drowsiness, especially if used during the day. It is also important to stay hydrated and you can continue to use a sinus rinse as well.
