Allergy Relief With Corticosteroid Injection
Temporary treatment of severe nasal allergy symptoms can be accomplished with a corticosteroid injection. It can also be effective in the treatment of asthma exacerbations. This treatment is reserved for those patients who have failed conventional therapy or who are unable to follow conventional treatment. If successful, the injections typically relieve symptoms for two-to-four weeks. If a patient continues to be exposed to allergens after that time, symptoms may recur. Most clinics require patients interested in corticosteroid injections to be fully evaluated by one of our clinicians before treatment. Due to the potential for side effects, we limit this treatment to one or two injections each year.
Before you consider this corticosteroid injection, you should be aware of the following:
- A corticosteroid injection is NOT an allergy shot. It is the injection of medicine which will result in the temporary relief of allergy symptoms.
- You may NOT receive the shot if you are diabetic, hypertensive, have a history of peptic ulcers or have an active infection.
- Corticosteroid injections will not be given to children.
- The injection will be given in the muscle of your hip. An uncommon side effect is subcutaneous atrophy. This atrophy manifests as a breakdown of the skin and underlying tissues, which may result in a permanent dimple. In some cases there may be muscle atrophy, a breakdown of muscle, which may result in an even larger indentation at the site of injection. This adverse effect is not serious, but may be significant from a cosmetic standpoint.
- Corticosteroids have systemic effects, the most important of which is decreased bone density (osteoporosis). The injection may also decrease the body’s ability to fight infections. It is unlikely that just one corticosteroid injection per year will place a person at risk, but this is a possibility. For more information about adverse effects, please see the complete list below.
- A corticosteroid injection may temporarily block your body’s ability to produce its own corticosteroids in response to stress such as a serious illness, accident or surgery. Prior to the injection, please let us know if you have a serious illness, have had an accident or anticipate surgery within the next month after you receive your injection.
- You should inform any healthcare provider you see that you have received a corticosteroid injection.
