What this medicine is used for
Risedronate is used to treat osteoporosis, including osteoporosis caused by taking
steroids. It is also used to preserve bone mineral density in patients on long term
Throughout life, old bone is broken down and replaced with new bone. After the age
of 35, bone loss may occur faster than your body can replace it. Excessive bone loss
causes bones to become thinner and weaker, and therefore more likely to break.
Osteoporosis is a disease that gradually weakens bones. Early osteoporosis may not
show symptoms. However, if left untreated, it can result in broken bones. Osteoporosis
can also cause back pain, height loss and a curved back.
How it works
Risedronate works by slowing down the process of old bone being removed, which allows
the bone-forming cells time to rebuild normal bone. This reverses the progression
of osteoporosis by creating stronger bone which is less likely to fracture.
