This medication contains two active ingredients: Doxylamine succinate and Pyridoxine hydrochloride.

• Doxylamine succinate is an antihistamine that works by blocking the action of histamine, a substance in the body that causes allergic reactions. It competes with histamine at the H1-receptor binding sites, affecting areas such as the uterus, gastrointestinal tract, large blood vessels, and bronchial muscles.
• Pyridoxine hydrochloride is another term for Vitamin B6, which plays a crucial role in various bodily functions.
