What can be used for nausea/vomiting during pregnancy?

If diet and lifestyle changes don’t help, or if you have severe nausea and vomiting of pregnancy, you might need medical treatment. Your ob-gyn or other obstetric care provider will first want to know whether your symptoms are due to nausea and vomiting of pregnancy or another medical cause. If other causes are ruled out, you may be able to take certain medications:

• Vitamin B6 is a safe, over-the-counter treatment that may be tried first for nausea and vomiting of pregnancy.
• Doxylamine, a medication found in over-the-counter sleep aids, can be added if vitamin B6 alone does not relieve symptoms.
• A prescription drug that combines vitamin B6 and doxylamine is available. Both drugs, taken alone or together, have been found to be safe to take during pregnancy and have no harmful effects on the fetus.
