Alendronate is used to prevent and treat certain types of bone loss (osteoporosis) in adults. Osteoporosis causes bones to become thinner and break more easily. Your chance of developing osteoporosis increases as you age, after menopause, or if you are taking corticosteroid medications (such as prednisone) for a long time.This medication works by slowing bone loss. This effect helps maintain strong bones and reduce the risk of broken bones (fractures). Alendronate belongs to a class of drugs called bisphosphonates.
How to use alendronate oral
Read the Medication Guide provided by your pharmacist before you start taking alendronate and each time you get a refill. Follow the instructions very closely to make sure your body absorbs as much drug as possible and to reduce the risk of injury to your esophagus. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth once a day, after getting up for the day and before taking your first food, beverage, or other medication.

Then stay fully upright (sitting, standing, or walking) for at least 30 minutes and do not lie down until after your first food of the day. Alendronate works only if taken on an empty stomach. Wait at least 30 minutes (preferably 1 to 2 hours) after taking the medication before you eat or drink anything other than plain water.
