Benadryl Uses

Benadryl is part of a class of drugs called antihistamines. Specifically, it is an H1 receptor antagonist. This means that it blocks a specific type of histamine receptor in the body (known as H1 receptors). Since allergic reactions are partly caused by the release of histamine from certain cells in the body, Benadryl can help relieve or prevent allergy symptoms.

 

Benadryl also blocks acetylcholine receptors, an action which produces some of the bothersome side effects of the medication (such as dry mouth or difficulty urinating) but also makes the drug useful for some uses of the medications (such as for Parkinson's disease or for relieving a runny nose due to the common cold).

 

Like many antihistamines, Benadryl also works as a sedative. This action has made the medication useful as a sleep aid but also limits the usefulness of the medication for other uses (since drowsiness can be a bothersome side effect).

 

Oral Children's Benadryl products are approved for treating allergies (such as hay fever) in children ages six years and older. Adult Benadryl oral products are approved for treating allergies or cold symptoms in children ages six years and older. Topical (skin) products are approved for use in children ages two years and older.

 

Benadryl is usually not recommended as a medication to make a child drowsy. Not only can this practice be dangerous, but it is often ineffective. In fact, Benadryl can have an opposite effect on children, sometimes making them hyperactive.
