diphenhidramina

Diphenhydramine is an antihistamine that is commonly used to treat allergy symptoms such as sneezing, runny nose, itchy nose, itchy throat, and itchy or watery eyes. It is also used to relieve itching and redness caused by hives and other skin irritations. In addition, diphenhydramine can be used as a short-term sleep aid due to its sedative properties. It works by blocking the action of histamine, a substance in the body that causes allergy symptoms.

This medication is available over-the-counter in various forms, including tablets, capsules, liquids, and topical creams. It is important to follow the dosage instructions on the product label or as directed by a healthcare professional. Side effects can include drowsiness, dizziness, blurred vision, dry mouth, and constipation. Because of its sedative effects, it is not recommended to drive or operate heavy machinery after taking diphenhydramine. It may also interact with other medications, so consulting a doctor or pharmacist before use is advisable, especially for individuals with certain medical conditions such as glaucoma, an enlarged prostate, or breathing problems.
