Corticosteroid injections

A corticosteroid or steroid injection is used to reduce inflammation. It is often used to treat conditions such as arthritis, tendinitis, bursitis, and more specific conditions such as de Quervain's tenosynovitis and carpal tunnel syndrome.

The procedure is done by injecting corticosteroid directly into the affected area. The area might be painful after the injection. But most people have improvement after a few days.

    Corticosteroid Medicines

    Corticosteroid medicines—also called steroid medicines—are similar to natural hormones produced in the body that help control many necessary functions, including blood sugar and salt (electrolyte) levels, the body's water balance, and immune system function. These medicines may help provide relief for diseases that cause inflammation, such as lupus and rheumatoid arthritis.

    Common prescription steroid medicines include dexamethasone, hydrocortisone, and prednisone.

    Steroid medicines have many side effects. The side effects a person has may depend on the steroid dose and how long the medicine is taken. Side effects like problems sleeping, mood changes, weight gain, and increases in blood sugar may occur shortly after starting a steroid medicine. Other side effects like changes in the color and thickness of skin, formation of cataracts, increases in blood pressure, and a reduced ability to fight infections may develop over time or at higher doses.

    What effect can steroids have on blood sugar?

    Steroid medicine has many benefits. But one side effect of steroids is that they can raise your blood sugar level while you take them. In most cases, this is temporary.

    If you already have diabetes, you may notice that your blood sugars jump higher after you take steroids.

    Very rarely, taking steroids may lead to a new diagnosis of diabetes.
