Allergy Shots

Allergy Treatment Hospital in Varthur Road Bangalore

Allergy shots are repeated injections given over time, typically three to five years, to prevent or lessen allergic reactions. Immunotherapy, a method of medical care, includes allergy injections. The precise ingredient or compounds that set off your allergic reactions are present in minimal amounts in each allergy shot, and Allergens are what these are. The allergens in allergy shots are enough to boost your immune system but not enough to result in a full-blown allergic reaction.

Your doctor gradually increases the allergen dosage in each allergy shot, which aids in acclimating your body to the allergens (desensitisation). Over time, your immune system develops a tolerance to the allergens, which causes your allergy symptoms to lessen.

Why is it done?

You may benefit from allergy shots as a form of treatment if you:

  • Medications do not effectively control your symptoms, and you cannot altogether avoid the triggers of your allergic reactions.

  • The medications you must take for allergies can interfere with those medications or have severe side effects.

  • You want to stop taking allergy medications for a long time.

  • You have an allergy to bee stings.

Using allergy shots, you can manage symptoms brought on by:

  • Allergy season - You can be allergic to pollens from trees, grasses, or weeds if you experience seasonal asthma or hay fever symptoms.

  • Allergens within - If your symptoms persist throughout the year; you may be susceptible to indoor allergens such as dust mites, cockroaches, mildew, or dog or cat hair.

  • Stinging insects - Bees, wasps, hornets, and yellow jackets can all cause allergic reactions to bug stings.

Food allergies and persistent hives don't have allergy shots accessible (urticaria).


Typically, allergy injections are given into the upper arm.

Allergy shots must be administered on a schedule with two stages for them to be effective:

  • Typically, the buildup phase lasts three to six months. Shots generally are administered once to three times per week, and each shot given during the building phase steadily increases the allergen dose.

  • Typically, the maintenance phase lasts for three to five years or more. About once each month, you'll require maintenance shots.

The building phase can sometimes be completed more quickly (rush immunotherapy); however, this method calls for many injections at gradually higher doses during each doctor's appointment. This can shorten the time it takes to enter the maintenance phase and experience relief from allergy symptoms, but it also raises the likelihood that you'll experience a severe reaction.

After each shot, you must stay in the doctor's office for 30 minutes in case of an adverse reaction.
