Important Administration Instructions

Instruct patients to do the following:

  • Take FOSAMAX PLUS D at least one-half hour before the first food, beverage, or medication of the day with plain water only [see Patient Counseling Information (17.2)]. Other beverages (including mineral water), food, and some medications are likely to reduce the absorption of alendronate [see Drug Interactions (7.1)]. Waiting less than 30 minutes, or taking FOSAMAX PLUS D with food, beverages (other than plain water) or other medications will lessen the effect of alendronate by decreasing its absorption into the body.
  • Take FOSAMAX PLUS D upon arising for the day. To facilitate delivery to the stomach and thus reduce the potential for esophageal irritation, a FOSAMAX PLUS D tablet should be swallowed with a full glass of water (6-8 ounces). Patients should not lie down for at least 30 minutes and until after their first food of the day. FOSAMAX PLUS D 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 and Precautions (5.1) and Patient Counseling Information (17.2)].

Recommendations for Calcium and Vitamin D Supplementation

Instruct patients to take supplemental calcium if dietary intake is inadequate [see Warnings and Precautions (5.2)]. Patients at increased risk for vitamin D insufficiency (e.g., over the age of 70 years, nursing home bound, or chronically ill) may need additional vitamin D supplementation. Patients with gastrointestinal malabsorption syndromes may require higher doses of vitamin D supplementation and measurement of 25-hydroxyvitamin D should be considered.

The recommended intake of vitamin D is 400-800 international units daily. FOSAMAX PLUS D 70 mg/2800 international units and 70 mg/5600 international units are intended to provide seven days' worth of 400 and 800 international units daily vitamin D in a single, once-weekly dose, respectively.

Administration Instructions for Missed Doses

If a once-weekly dose of FOSAMAX PLUS D is missed, instruct patients to take one tablet on the morning after they remember. They should not take two tablets on the same day but should return to taking one tablet once a week, as originally scheduled on their chosen day.
