Benadryl

Benadryl is a brand of over-the-counter medication produced by Johnson & Johnson. It is commonly used to treat various types of allergies, including hay fever, hives, and allergic reactions to insect bites or stings. Benadryl's active ingredient is diphenhydramine, which is an antihistamine that helps to relieve symptoms such as itching, sneezing, and runny nose.

Benadryl is available in different forms, including tablets, capsules, liquid gels, and topical creams. It is typically taken orally, but can also be applied topically to the skin to relieve itching and redness. Benadryl is considered safe for most people when taken as directed, although it may cause drowsiness in some individuals.

In addition to treating allergies, Benadryl is sometimes used to help with sleep, as it can cause drowsiness. However, it is not recommended for long-term use as a sleep aid.
