DOXYLAMINE

Doxylamine is used in the short-term treatment of insomnia (difficulty falling asleep or staying asleep). Doxylamine is also used in combination with decongestants and other medications to relieve sneezing, runny nose, and nasal congestion caused by the common cold. Doxylamine should not be used to cause sleepiness in children. Doxylamine is in a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.
Doxylamine comes as a tablet to take by mouth for sleep, and in combination with other medications as a liquid and liquid-filled capsule to treat symptoms of the common cold. When doxylamine is used to reduce difficulty falling asleep, it usually is taken 30 minutes before bedtime. When doxylamine is used to treat cold symptoms, it is usually taken every 4 to 6 hours. Follow the directions on the package label or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take doxylamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor or directed on the package label.
