Doxylamine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. This medication works by blocking certain natural substances (histamine, acetylcholine) that your body makes. This effect helps to relieve allergy/cold symptoms such as watery eyes, runny nose, and sneezing. It is also effective in treating insomnia.
