Alendronate sodium 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 Alendronate sodium tablets, USP are indicated for the treatment of osteoporosis in postmenopausal women.

[See Clinical Studies ( 14.1 ).] 1.2 Prevention of Osteoporosis in Postmenopausal Women Alendronate sodium tablets, USP are indicated for the prevention of postmenopausal osteoporosis [see Clinical Studies ( 14.2 )]. 1.3 Treatment to Increase Bone Mass in Men with Osteoporosis Alendronate sodium tablets, USP are indicated for treatment to increase bone mass in men with osteoporosis [see Clinical Studies ( 14.3 )]. 1.4 Treatment of Glucocorticoid-Induced Osteoporosis Alendronate sodium tablets, USP are 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 …

Alendronate sodium tablets are contraindicated in patients with the following conditions: Inability to stand or sit upright for at least 30 minutes [see Dosage and Administration ( 2.6 ); Warnings and Precautions ( 5.1 )] Hypocalcemia [see Warnings and Precautions ( 5.2 )] Hypersensitivity to any component of this product. Hypersensitivity reactions including urticaria and angioedema have been reported [see Adverse Reactions ( 6.2 )] . Abnormalities of the esophagus which delay esophageal emptying such as stricture or achalasia [see Warnings and Precautions ( 4 , 5.1 )] Inability to stand/sit upright for at least 30 minutes ( 2.6 , 4 , 5.1 ) Hypocalcemia ( 4 , 5.2 ) Hypersensitivity to any component of this product ( 4 , 6.2 )

Upper Gastrointestinal Adverse Reactions can occur. Instruct patients to follow dosing instructions. Discontinue if new or worsening symptoms occur. ( 5.1 ) Hypocalcemia can worsen and must be corrected prior to use. ( 5.2 ) Severe Bone, Joint, Muscle Pain may occur. Discontinue use if severe symptoms develop. ( 5.3 ) Osteonecrosis of the Jaw has been reported. ( 5.4 ) Atypical Fractures Including Femoral Fractures have been reported. Patients with new thigh or groin pain should be evaluated to rule out a femoral fracture. Risk/benefit of continuing bisphosphonate therapy should be re-evaluated in these patients and interruption of bisphosphonate therapy should be considered ( 5.5 ) 5.1 Upper Gastrointestinal Adverse Reactions Alendronate sodium, like other bisphosphonates administered orally, may cause local irritation of the upper gastrointestinal mucosa. Because of these possible irritant effects and a potential for worsening of the underlying disease, caution should be used when alendronate sodium is given to patients with active upper gastrointestinal problems (such as known Barrett's esophagus, dysphagia, other esophageal diseases, gastritis, duodenitis, or ulcers). Esophageal adverse experiences, such as esophagitis, esophageal ulcers and esophageal erosions, occasionally with bleeding and rarely followed by esophageal stricture or perforation, have been reported in patients receiving treatment with oral bisphosphonates including alendronate sodium. In some cases …

8.1 Pregnancy Risk Summary Available data on the use of alendronate sodium in pregnant women are insufficient to inform a drug-associated risk of adverse maternal or fetal outcomes. Discontinue alendronate sodium when pregnancy is recognized. In animal reproduction studies, daily oral administration of alendronate to rats from before mating through the end of gestation or lactation showed decreased postimplantation survival and decreased pup body weight gain starting at doses equivalent to less than half of the highest recommended 40 mg clinical daily dose (based on body surface area, mg/m 2 ). Oral administration of alendronate to rats during organogenesis resulted in reduced fetal …
