Certain antihistamines such as dimenhydrinate or doxylamine, taken as your doctor advises, may relieve morning sickness.footnote 1 Doxylamine (Unisom SleepTabs) is available over-the-counter. If one of these antihistamines alone does not relieve your morning sickness, you can try taking it with vitamin B6.footnote 1 Talk to your doctor about the right dose.
