How often cortisone injections are given varies based on the reason for the injection. This is determined on a case-by-case basis by the health care practitioner. If a single cortisone injection is curative, then further injections are unnecessary. Sometimes, a series of injections might be necessary; for example, cortisone injections for a trigger finger may be given every three weeks, to a maximum of three times in one affected finger. In other instances, such as knee osteoarthritis, a second cortisone injection may be given approximately three months after the first injection, but the injections are not generally continued on a regular basis.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http:///c4Rm4p ) for more information if you do not have access to a take-back program.
Normally the adrenal glands release cortisol into the blood stream every morning. The brain monitors this amount and regulates the adrenal function. It cannot tell the difference between its own natural cortisone and that of steroid medicines. Therefore, when a person takes high doses of steroids over a long time, the brain may decrease or stop cortisol production. This is called adrenal suppression. Healthcare providers generally decrease a steroid dosage slowly to allow the adrenal gland to recover and produce cortisol at a normal level again. If you have been on steroids long-term do not stop taking them suddenly. Follow your doctor's prescription.
