When to use Fosamax?

Fosamax alters the cycle of bone formation and breakdown in the body. As stated earlier, Fosamax slows bone loss while increasing bone mass, which may prevent bone fractures.

”Resorption” is the process of reducing bone degeneration. It is the effect of Fosamax which is again a bipshosphonate drug usually prescribed for men and women with osteoporosis. Fosamax is also used to cure Paget’s disease of bone in men and women.

To treat osteoporosis, Fosamax is used to increase bone mass and reduces the possibility of fractures including the hip’s and spine’s.

Furthermore, for the prevention of osteoporosis, Fosamax may be considered in postmenopausal women who are at risk of developing osteoporosis and for whom the desired clinical outcome is to maintain bone mass and to reduce the risk of future fracture. Bone loss is particularly rapid in postmenopausal women younger than age 60. Risk factors often associated with the development of postmenopausal osteoporosis include early menopause.

Paget’s disease is also treated by Fosamax. Bone having alkaline phosphatase at least two times the normal limit is what puts the person into the risk of getting this disease.
