Banadryl is a medication that is used to treat allergies and the inflammation associated with allergies.

It belongs to a group of medicines known as antihistamines, and it works by stopping the natural chemical histamine from being released in the body.

Histamine is released as part of an allergic response, and it causes symptoms such as sneezing, itching, watery eyes, and runny nose. Banadryl helps relieve these symptoms for up to 12 hours or longer if you need it for both morning and evening doses.

It can be taken at any time of day with or without food.
Side effects may include dry mouth, drowsiness or tiredness, dizziness, blurred vision. If you notice any unusual symptoms, stop taking Banadryl and talk to your doctor.

The active ingredient in Banadryl is chlorphenamine maleate.
It is available in capsule form, containing either 30 mg or 60 mg of the active ingredient per dose.

It was approved by the FDA on February 26, 1970.

You should take this medicine exactly as it was prescribed for you. Do not take more or less of it or take it more often than prescribed by your doctor (a common mistake is to take the morning dose while in bed). You should not change your dose unless instructed to do so by your doctor.
