Benadryl Information

Benadryl (diphenhydramine) is a common over-the-counter (OTC) medication used to treat a variety of conditions, primarily related to allergic reactions. As a first-generation antihistamine, its active ingredient, diphenhydramine hydrochloride, works by blocking the effects of histamine, a natural substance in the body that triggers allergic symptoms. Specifically, it acts as an inverse agonist at the H1 histamine receptor, reversing the effects of histamine on capillaries and smooth muscles, thereby reducing symptoms like sneezing, a runny nose, and itching.

Beyond its role as an antihistamine, Benadryl also has other pharmacological properties. It possesses strong anticholinergic (drying) effects, which can help to alleviate symptoms such as a runny nose and watery eyes. These anticholinergic properties are also responsible for some of its side effects, like dry mouth and blurred vision. Additionally, because diphenhydramine readily crosses the blood-brain barrier, it can cause central nervous system (CNS) depression, leading to drowsiness. This sedative effect is why Benadryl is also used as a short-term nighttime sleep aid.

Diphenhydramine is used to treat a range of conditions, including hay fever, other upper respiratory allergies, and the common cold. It is also effective in providing relief from itching and pain associated with insect bites and stings, hives, and other skin irritations. In some cases, injectable forms of diphenhydramine are used in clinical settings for more severe allergic reactions or to manage symptoms of motion sickness and certain movement disorders, such as drug-induced extrapyramidal symptoms or Parkinsonism.
