    Antihistamines for Morning Sickness

    Topic Overview

    Certain antihistamines such as dimenhydrinate or doxylamine, taken as your doctor advises, may relieve morning sickness. 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. 1 Talk to your doctor about the right dose.

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

    A prescription medicine that combines doxylamine and vitamin B6 in one medicine (called Diclegis) is also available to treat morning sickness.

    Common side effects of these medicines may include:

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