Doxylamine and Pyridoxine
Doxylamine and pyridoxine is a drug used to help reduce the symptoms of "morning sickness" in pregnant women who are unable to control nausea and vomiting through diet changes or other nonmedicine methods. This combination medication contains an antihistamine and vitamin B6. It comes as a tablet that is taken one to four times daily, depending on how you respond to the drug.

Just like any medicine, doxylamine and pyridoxine can cause side effects. However, not everyone who uses the drug will experience problems. Most people tolerate it quite well.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious side effects are less common.
Drowsiness is the most common doxylamine and pyridoxine side effect.
