1. Adults : Administer 35 mg of risedronate sodium orally once weekly. 2.

For adequate absorption, take it at least 30 minutes before breakfast, or at least 2 hours before or after food or beverages at any time of day. To facilitate passage of this drug into the stomach and reduce the possibility of esophageal irritation, take it while sitting or standing upright with a sufficient amount of plain water (170 ∼ 230 mL). Taking it with other beverages, including mineral water, may decrease absorption. Do not chew or suck this drug because of the possibility of oropharyngeal ulceration.

Resume the next dose on the originally scheduled day. Do not take 2 tablets on the same day.
