Doctors prescribe alendronate sodium tablets, marketed as Fosamax, to increase bone density and slow bone loss, states Drugs.com. The tablets prevent and treat osteoporosis in postmenopausal women and increase bone mass in men. They treat Paget's disease of bone and glucocorticoid-induced osteoporosis in men and women.
Common side effects of alendronate sodium tablets include diarrhea, constipation, dizziness and mild muscle or joint pain, notes Drugs.com. Glucocorticoid medicines, such as prednisone and cortisone, affect bone cells, interfere with calcium processing, and impact sex hormone levels, states the American College of Rheumatology. These problems slow the rate of new bone formation and lead to increased bone loss.
Paget’s disease is a chronic disorder that results in misshapen and enlarged bones due to weakened bone tissue. It affects just a few bones in the body, unlike osteoporosis, which affects all bones, according to the National Institutes of Health.
