Summary
Doxylamine is used to relieve allergy symptoms like sneezing and runny nose, which are caused by the body's reaction to allergens. It is also used as a short-term sleep aid, which helps people fall asleep more easily due to its sedative effects.
Doxylamine works by blocking histamine, which is a chemical in the body that causes allergy symptoms. This action helps reduce symptoms like sneezing and itching. It also has sedative effects, which promote drowsiness and help with sleep.
The usual dose of Doxylamine for adults is 25 mg taken once daily at bedtime. It can be taken with or without food. For children or the elderly, the dose may be adjusted by a doctor. Always follow your doctor's specific dosing instructions.
Common side effects of Doxylamine include drowsiness, which is a feeling of being sleepy, dry mouth, which is a lack of saliva, and dizziness, which is a sensation of spinning or losing balance. These effects are usually mild and temporary.
Avoid alcohol while taking Doxylamine, as it can increase drowsiness. Do not use if you have severe breathing problems, glaucoma, which is increased pressure in the eye, or an enlarged prostate, which can cause urinary issues. Always consult your doctor before use.
