What Risedronate Bluefish is and what it is used for

What Risedronate Bluefish is

Risedronate Bluefish belongs to a group of non-hormonal medicines called bisphosphonates which are used to treat skeletal diseases. The drug has a direct effect on the skeleton by making it stronger and thereby reducing the likelihood that you will suffer a bone fracture.

Bone is living tissue. Old bone disappears continuously from your skeleton and is replaced with new bone.

Postmenopausal osteoporosis (osteoporosis) is a condition that affects women after menopause (menopause) when the skeleton becomes weaker and more fragile and bone fractures are more likely in connection with falls or stress. Osteoporosis can also affect men for several reasons including aging and/or low levels of the male sex hormone testosterone.

The vertebrae, hips, and wrists are the bones that are usually broken, although it can happen to any bone in your body. Fractures due to osteoporosis can also cause back pain, shorten body length and give a curved back. Many patients with osteoporosis do not experience any symptoms and you may not even know you have the disease.

What Risedronate Bluefish is used for

Risedronate Bluefish is used to treat osteoporosis (osteoporosis) in postmenopausal women. It reduces the risk of bone fractures in the spine and hip.

Risedronate Bluefish is used to treat osteoporosis in men at high risk of bone fractures.
