Inflammation is the body's protective response to irritation or injury, and is characterized by redness, warmth, swelling and pain. They also may relieve pain that is not caused by inflammation, such pain resulting from bruises or headaches.
Steroids are synthetic drugs that closely resemble cortisone, a naturally occurring hormone.
Also, generic drugs are less expensive than brand-name drugs. Dosages may range from one to four times per day, depending on how long each drug remains active. Lower doses may be adequate for osteoarthritis and acute muscle injuries, since there is generally less swelling and often no warmth or redness to the joints. Some side effects are mild and go away on their own or after reducing the dose. Other side effects may be more serious and need medical attention.
