Benadryl
DESCRIPTION

Benadryl is an allergy and itch relief medication prescribed for adults and children.

How It Works

The active ingredient in Benadryl is an antihistamine called diphenhydramine. Antihistamines block the immune system from producing a substance called histamines. Immune system uses histamines to fight off foreign bodies (allergens, viruses, pollen, etc) that enter the body, resulting in issues such as inflammation and hives. By blocking the production of histamines, Benadryl can relieve symptoms of common allergies.

Uses

Benadryl is used to treat allergic reactions, hay fever and symptoms of cold. It is also used to reduce the itchiness, swelling and inflammation caused by poison ivy, poison oak, insect bites, poison sumac, minor cuts or burns. Injections of Benadryl are also used to treat severe allergic reactions, motion sickness and occasionally symptoms of mild Parkinson’s disease.

Because Benadryl can reduce symptoms such as nasal congestions, it is also prescribed to treat insomnia. People who snore, which can be caused by nasal obstructions, may also be advised to use antihistamines like Benadryl to clear up the nasal passageways to relieve snoring.

Benadryl can be applied topically onto skin, taken orally or injected depending on the condition that requires treatment.

Dosage

Dosage of Benadryl varies depending on the form of the medication being used. A doctor may prescribe a set dosage of Benadryl when taken orally or injected.

Benadryl topical cream should be applied evenly onto the skin to treat skin inflammation, swelling or itching. Use a small amount and rub gently, or do as instructed by a physician.

Your doctor will prescribe a suitable dosage of Benadryl oral tablets depending on your condition, severity and response to treatment. Follow the doctor’s instructions exactly as prescribed when taking Benadryl orally.

If Benadryl is prescribed to be taken according to a dosage schedule, follow the schedule exactly as instructed. Do not miss doses or take more of the drug than advised. Taking higher doses of Benadryl in any form can result in unintended side effects.

Side Effects

Benadryl may cause one or more of the following side effects:

Sedation
Sleepiness
