Antihistamines for Morning Sickness

Overview

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.

Do not confuse Unisom SleepTabs with Unisom SleepGels, which contain a different medicine.

If home treatment does not work for you, talk to your doctor about medicine that may help relieve your symptoms.

Common side effects of these medicines may include:

• Drowsiness.
• Dry mouth, nose, or throat.
