How are food allergies and intolerances usually treated?

People with food allergies are usually told to avoid the problem food. The same is true for people with food intolerances.

Beyond that, treatment depends on how severe your problem is. You may need to see an allergist, a doctor who specializes in allergies.

Unfortunately, there's no medicine you can take to prevent an allergic reaction. But there is medicine to help you if you accidentally eat something you shouldn't.

For instance, antihistamines can help hives, sneezing, and runny nose. These are available over-the-counter and by prescription.

If you tend to develop anaphylaxis or have severe allergic reactions, your doctor may order a syringe or a pen-like device filled with epinephrine for you. You will need to inject yourself with this if you think you are getting a severe reaction. Even if you seem OK after taking epinephrine for a severe reaction, you need to go to the hospital right away because your symptoms might come back.

If you have severe reactions, you also should wear a medical alert bracelet or necklace that says you have a food allergy. And always carry your medicine with you.
