Clinical summary
Indications and usage 1 INDICATIONS AND USAGE FOSAMAX is a bisphosphonate indicated for: Treatment and prevention of osteoporosis in postmenopausal women ( 1.1 , 1.2 ) Treatment to increase bone mass in men with osteoporosis ( 1.3 ) Treatment of glucocorticoid-induced osteoporosis ( 1.4 ) Treatment of Paget's disease of bone ( 1.5 ) Limitations of use : Optimal duration of use has not been determined. For patients at low-risk for fracture, consider drug discontinuation after 3 to 5 years of use. ( 1.6 ) 1.1 Treatment of Osteoporosis in Postmenopausal Women FOSAMAX ® is indicated for the treatment of osteoporosis in postmenopausal women. In postmenopausal women, FOSAMAX increases bone mass and reduces the incidence of fractures, including those of the hip and spine (vertebral compression fractures). [See Clinical Studies (14.1) .] 1.2 Prevention of Osteoporosis in Postmenopausal Women FOSAMAX is indicated for the prevention of postmenopausal osteoporosis [see Clinical Studies (14.2) ] . 1.3 Treatment to Increase Bone Mass in Men with Osteoporosis FOSAMAX is indicated for treatment to increase bone mass in men with osteoporosis [see Clinical Studies (14.3) ] . 1.4 Treatment of Glucocorticoid-Induced Osteoporosis FOSAMAX is indicated for the treatment of glucocorticoid-induced osteoporosis in men and women receiving glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and who have low bone mineral density [see Clinical Studies (14.4) ] . 1.5 Treatment of Paget's Disease of Bone FOSAMAX is indicated for the treatment of Paget's disease of bone in men and women. Treatment is indicated in patients with Paget's disease of bone who have alkaline phosphatase at least two times the upper limit of normal, or those who are symptomatic, or those at risk for future complications from their disease. [See Clinical Studies (14.5) .] 1.6 Important Limitations of Use The optimal duration of use has not been determined. The safety and effectiveness of FOSAMAX for the treatment of osteoporosis are based on clinical data of four years duration. All patients on bisphosphonate therapy should have the need for continued therapy re-evaluated on a periodic basis. Patients at low-risk for fracture should be considered for drug discontinuation after 3 to 5 years of use. Patients who discontinue therapy should have their risk for fracture re-evaluated periodically. Dosage and administration 2 DOSAGE AND ADMINISTRATION Although alendronate tablets 5 mg, 10 mg, 35 mg, and 40 mg are available in the marketplace, FOSAMAX is no longer marketed in the 5 mg, 10 mg, 35 mg, and 40 mg strengths.

( 2.1 , 2.3 ) Prevention of osteoporosis in postmenopausal women: 5 mg daily or 35 mg once weekly. ( 2.2 ) Glucocorticoid-induced osteoporosis: 5 mg daily; or 10 mg daily in postmenopausal women not receiving estrogen. ( 2.4 ) Paget's disease: 40 mg daily for six months. ( 2.5 ) Instruct patients to: ( 2.6 ) Swallow tablets whole with 6-8 ounces plain water at least 30 minutes before the first food, drink, or medication of the day. Swallow oral solution followed by at least 2 ounces of water. Not lie down for at least 30 minutes after taking FOSAMAX and until after food. 2.1 Treatment of Osteoporosis in Postmenopausal Women The recommended dosage is: one 70 mg tablet once weekly or one bottle of 70 mg oral solution once weekly or one 10 mg tablet once daily 2.2 Prevention of Osteoporosis in Postmenopausal Women The recommended dosage is: one 35 mg tablet once weekly or one 5 mg tablet once daily 2.3 Treatment to Increase Bone Mass in Men with Osteoporosis The recommended dosage is: one 70 mg tablet once weekly or one bottle of 70 mg oral solution once weekly or one 10 mg tablet once daily 2.4 Treatment of Glucocorticoid-Induced Osteoporosis The recommended dosage is one 5 mg tablet once daily, except for postmenopausal women not receiving estrogen, for whom the recommended dosage is one 10 mg tablet once daily. 2.5 Treatment of Paget's Disease of Bone The recommended treatment regimen is 40 mg once a day for six months. Re-treatment of Paget's Disease Re-treatment with FOSAMAX may be considered, following a six-month post-treatment evaluation period in patients who have relapsed, based on increases in serum alkaline phosphatase, which should be measured periodically. Re-treatment may also be considered in those who failed to normalize their serum alkaline phosphatase. 2.6 Important Administration Instructions Instruct patients to do the following: Take FOSAMAX at least one-half hour before the first food, beverage, or medication of the day with plain water only [see Patient Counseling Information (17) ].
