Common Brand Name(s): Fosavance

Important: How To Use This Information

This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

Uses

This medication is used to treat certain types of bone loss (osteoporosis) and to increase bone mass. 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 product is a combination of two medicines: alendronate and cholecalciferol (vitamin D3). Alendronate works by slowing bone loss to help maintain strong bones and reduce the risk of broken bones (fractures). It belongs to a class of medications called bisphosphonates. Vitamin D3 helps your body absorb calcium and is necessary for building healthy bones.

How To Use

Read the Medication Guide provided by your pharmacist before you start taking this medication 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.

This medication is usually taken once per week unless otherwise directed by your doctor. Choose the day of the week that best fits your schedule and take it on that day each week.
