Doxylamine is a first-generation antihistamine used for trouble sleeping and allergies. Use for trouble sleeping should be short term. Onset of effects is about half an hour. It is also used in combination with vitamin B6 (pyridoxine) for nausea and vomiting of pregnancy. It is taken by mouth.

Common side effects include sleepiness. Other side effects include dry mouth, urinary retention, and glaucoma. Children may get restless. Use in pregnancy appears safe. It works by blocking H1 receptors and thus blocking the effects of histamine.

Doxylamine was first described in 1948. It is available as a generic medication. In the United States it costs less than 10 USD for 30 tablets of 25 mg as of 2020.
