Allergy shots can be beneficial for those that have allergies and asthma, as allergies are typically a trigger for asthma. While allergy shots are not a cure for asthma, they are an aid to reduce symptoms. Since an allergy shot is injecting a tiny dose of allergen into your body, overtime you will build up immunity to the allergen. Then, your body will be less susceptible to an asthma attack that has been brought on by an allergen.
Immunotherapy begins when your physician has properly diagnosed your allergy. The first stage of immunotherapy is called the buildup phase. During this phase, you will be required to have injections twice per week. This stage may last up to six months. Once this phase is complete, then you will move into the maintenance phase. During the maintenance phase, you will receive injections once or twice per month for about five years. After injections, you will be asked to stay at the office for 30 minutes to watch for a reaction.
There are not many risks of immunotherapy. Common side effects are a bump on the injection site and that may turn red. Some patients also experience allergy symptoms after injections. It is best to take an antihistamine to help ease these symptoms. In very rare cases do severe allergic reactions occur, but this is why you will be asked to stay in the allergist's office for up to 30 minutes after the injection.
