Alendronate sodium tablets, USP must be taken at least one-half hour before the first food, beverage, or medication of the day with plain water only (see PRECAUTIONS, Information for Patients). Other beverages (including mineral water), food, and some medications are likely to reduce the absorption of alendronate sodium tablets (see PRECAUTIONS, Drug Interactions). Waiting less than 30 minutes, or taking alendronate sodium tablets with food, beverages (other than plain water) or other medications will lessen the effect of alendronate sodium tablets by decreasing its absorption into the body.
Alendronate sodium tablets should only be taken upon arising for the day. To facilitate delivery to the stomach and thus reduce the potential for esophageal irritation, an alendronate sodium tablet should be swallowed with a full glass of water (6 - 8 oz). Patients should not lie down for at least 30 minutes and until after their first food of the day. Alendronate sodium tablets should not be taken at bedtime or before arising for the day. Failure to follow these instructions may increase the risk of esophageal adverse experiences (see WARNINGS, PRECAUTIONS, Information for Patients).
Patients should receive supplemental calcium and vitamin D, if dietary intake is inadequate (see PRECAUTIONS, General).
No dosage adjustment is necessary for the elderly or for patients with mild-to-moderate renal insufficiency (creatinine clearance 35 to 60 mL/min). Alendronate sodium tablets are not recommended for patients with more severe renal insufficiency (creatinine clearance <35 mL/min) due to lack of experience.

Paget's disease of bone in men and women
The recommended treatment regimen is 40 mg once a day for six months.
Retreatment of Paget's disease
In clinical studies in which patients were followed every six months, relapses during the 12 months following therapy occurred in 9% (3 out of 32) of patients who responded to treatment with alendronate sodium tablets. Specific retreatment data are not available, although responses to alendronate sodium tablets were similar in patients who had received prior bisphosphonate therapy and those who had not. Retreatment with alendronate sodium tablets 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. Retreatment may also be considered in those who failed to normalize their serum alkaline phosphatase.
