Doxylamine

Doxylamine is an antihistamine primarily used as a short-term sleep aid and to relieve allergic symptoms like sneezing and runny nose. It works by blocking certain brain chemicals involved in allergy responses and promoting drowsiness. Doxylamine can cause side effects such as dry mouth, dizziness, and blurred vision, and should be used cautiously, especially in older adults or alongside other medications. It’s available over-the-counter and generally intended for occasional use to help with sleep or allergy relief. Always follow dosing instructions and consult a healthcare professional if you have underlying conditions or are taking other drugs.
