Allergy Steroid Injection
Allergies occur when the immune system recognizes a foreign substance as a threat. These foreign substances are called allergens, and they don’t trigger a reaction in some other people.
Pollen from grass and other plants are allergens that are present during certain times of the year. When you come into contact with these allergens, your immune system goes on the defensive, causing symptoms such as sneezing, nasal congestion, and itchy or watery eyes.
Seasonal allergies, also known as hay fever or allergic rhinitis, have no cure. However, there are a number of effective medical treatments. Some of these include:
- Mast cell stabilizers
Corticosteroids, a type of steroid hormone, are available as nasal sprays, topical creams, pills, and long-lasting injections. They work by suppressing inflammation caused by an overly reactive immune system.
When it comes to treating seasonal allergies, corticosteroid injections are a last resort. They are prescribed when other treatments don’t work and symptoms interfere with everyday activities. They’re not the same as immunotherapy injections, which don’t include steroids.
Taking steroid shots for a prolonged period of time increases the risk of more serious side effects. Long-term side effects can include:
- Osteoporosis and fractures
- Cushing Syndrome
- Increased risk of heart disease
- Herpes Keratitis
- Hormonal Suppression
- Peptic Ulcers
- Psychological symptoms, such as depression or psychosis
- Severe Hypertension
- Tuberculosis and other chronic infections
- Venous Thromboembolism
Side Effects For People With Chronic Conditions
Since corticosteroids shots suppress inflammation and your immune response, they can hide common signs of illness and infection, putting you at risk.
People with certain chronic conditions may be at an increased risk for serious side effects as the result of a steroid shot for allergies. Be sure to let your doctor or allergist know if have or had any of the following conditions:
- Fungal Infections
- Heart Attack
- Mental Illness
- An untreated infection
How Long Does A Steroid Shot Allergies last?
Long-lasting steroid shots for allergies can last between three weeks and three months. During this time, the steroid is slowly released into your body.
A long-lasting shot may mean that you only require one shot per allergy season.
However, long-lasting shots come with risks. In particular, there's no way to remove the steroid from your body if you experience side effects.
