This combination medication (doxylamine with pyridoxine) is used to prevent or reduce nausea and vomiting caused by pregnancy. Decreasing nausea and vomiting may improve your health and nutrition during pregnancy. Doxylamine is an antihistamine that is thought to work by affecting certain natural substances (acetylcholine, serotonin) in your body or by acting directly on certain parts of the brain. Pyridoxine is a B vitamin that is important for good health. Most people get enough pyridoxine in their diet, but certain health conditions (e.g., pregnancy, poor diet, alcoholism) can result in a lack of this vitamin.
