Do Allergy Shots Work for All Allergies?

A lot depends on how many things you are allergic to and how severe your symptoms are. Generally, allergy shots work for allergies to bee stings, pollen, dust mites, mold, and pet dander. There’s no proof that they work for food, drug, or latex allergies.

When Should I Call My Doctor?

Call your doctor and go to the nearest emergency room if you develop shortness of breath, tight throat, or any other symptoms that worry you after getting your shot.

Do I Have to Get a Shot?

The FDA has approved three under-the-tongue tablets that can be taken at home. The prescription tablets, called Grastek, Ragwitek, and Oralair, are used for treating hay fever and work the same way as shots and drops -- the goal is to boost a patient’s tolerance of allergy triggers.

What Is Rush Immunotherapy?

Rush immunotherapy is a faster way to get to a maintenance dose, but it is riskier. During the first part of the treatment, you get doses of the allergen every few hours instead of every few days. It’s usually done under very close monitoring so that doctors can keep an eye on you, because there’s a greater chance that you’ll have a body-wide reaction. That can be dangerous. In some cases, you may get medications before you get the dose of the allergen, to reduce the risk of a reaction.

Who Should Not Get Allergy Shots?

Allergy shots may be more risky for people with heart or lung disease, or who take certain medications. Be sure to tell your allergist about your health and any medicines you take, so you can decide if allergy shots are right for you.
