Are allergy shots harmful?
Allergy shots are usually safe. But because allergy shots contain small amounts of an allergen you might have an allergic reaction to the shot itself. One common reaction to allergy shots is swelling at the place where the shot is given. Some people can also have severe, shock-like reactions to an allergy shot. This type of reaction is called anaphylaxis. Anaphylaxis is rare but very serious. If you get your shots on schedule (every week or every month), you’re less likely to have this kind of reaction. In case you have a bad reaction, your doctor will have you stay at the office for about 20 minutes every time you get your shot. That way, if you have a reaction to the shot, your doctor can give you something right away to stop it.
