Health Tip: Using an Antihistamine

(HealthDay News) -- Antihistamines are medications used to prevent or treat allergy symptoms. Many of these medicines may be bought without a doctor's prescription.

The American Academy of Family Physicians has issued these guidelines for people who take an over-the-counter antihistamine:

Before you take an antihistamine, talk to your doctor if you have a chronic health condition, including heart disease, high blood pressure or thyroid disease.

Before you take an antihistamine, talk to your doctor if you also take a sleeping pill, sedative or muscle relaxant. These other medicines may interact with an antihistamine.

If you take an antihistamine that is combined with a decongestant or pain reliever, carefully check the label for potential interactions with your other medications.

Be careful that you aren't taking more than one medication that contains an antihistamine. This could cause you to take more than you need.
