Alendronate

This form:

Pronounced

"a-LEN-droe-nate"

Common brand names:

Fosamax

Uses

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 This Medication

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 as directed by your doctor, usually once a day. Take this medication after getting up for the day and before taking your first food, beverage, or other medication. Take it with a full glass (6-8 ounces or 180-240 milliliters) of plain water. Swallow the tablet whole. Do not chew or suck on it. 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.

Do not take this medication at bedtime or before rising for the day. It may not be absorbed and you may have side effects.

Calcium or iron supplements, vitamins, antacids, coffee, tea, soda, mineral water, calcium-enriched juices, and food can decrease the absorption of alendronate. Do not take these for at least 30 minutes (preferably 1 to 2 hours) after taking alendronate.

Take this medication regularly to get the most benefit from it. Remember to use it at the same time each morning. Talk to your doctor about the risks and benefits of long-term use of this medication.
