Steroid shots can relieve symptoms triggered by inflammation, including inflammation triggered by allergies.
This reduces inflammation and sometimes eliminates allergy symptoms.
What Steroid Shots Do for Allergies
Steroid shots for allergies target both immediate and long-term allergy symptoms.

The steroid is slowly released into your body and usually continues working for a few weeks.
They treat allergy symptoms by decreasing inflammation throughout the body.
Diabetic medication dosages may need to be adjusted.
Salt restriction and potassium supplementation may be necessary.
Weakened Immune System
Corticosteroids reduce the activity of your immune system.
The rate of these complications increases with higher doses.
Chicken pox and measles can be more serious or even fatal in adults and children receiving steroid shots.
Speak with your healthcare provider before gettinganyvaccinationswhile being treated with steroid injections for allergies.
This can be triggered by prolonged use of corticosteroid drugs, including steroid shots for allergies.
Steroid therapies must be gradually tapered off to avoid adrenal suppression.
Long-term use of steroid shots for allergies may also lead to the suppression of bone growth in children.
Obesity
Prolonged use of corticosteroids affects metabolism and how fat deposits are distributed in your body.
Steroid use leads to increased appetite, subsequent weight gain, and added fat in your abdomen.
Immunotherapy is commonly administered as allergy shots (injection) orsublinguallywith allergy drops or tablets placed under the tongue.
Not all allergies can be treated with immunotherapy.
They relieve nasal congestion and inflammation but must be used daily for a few weeks to be most effective.
Mast Cell Stabilizers
Mast cell stabilizers keep mast cells from releasing histamine.
They are available for use in inhalers, nasal sprays, and eye drops.
These medications tend to work best for prevention.
Antihistamines
Histamine is released whenever an allergen triggers your body.
Long-acting corticosteroid injections prevent the immune system from overreacting to allergens.
Side effects include increased appetite, difficulty sleeping, and short or long-term weight gain.
Complications from long-term steroid use can include vision problems, adrenal disorders, and a weakened immune system.
