risedronate

By Warner Chilcott

What is this medication for?

Risedronate belongs to a family of medications known as bisphosphonates. It is used to treat and prevent osteoporosis for women who are past menopause. It is also used to treat osteoporosis in men, to prevent and treat osteoporosis in men and women taking high doses of corticosteroids, and to treat men and women with a condition called Paget's disease.

Risedronate increases the thickness of bone (bone mineral density) by slowing down the cells that usually break down bone (osteoclasts). This allows the cells that build bone (osteoblasts) to work more efficiently. By making bones stronger, risedronate can help to reduce the risk of broken bones.

To further help reduce the risk of broken bones, weight-bearing exercise should be considered along with stopping or decreasing cigarette smoking and/or drinking alcoholic beverages.

The optimal length of treatment using risedronate has not been determined, talk to your doctor about how long you should be taking risedronate.

Your doctor may have suggested this medication for conditions other than those listed here. As well, some forms of this medication may not be used for all of the conditions discussed here. If you are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
