Drug Information
5 reviews for Alendronate (Fosamax)
Fosamax contains Alendronate.
Alendronate is a bisphosphonate medicine that strengthens bones. It is used to treat and prevent osteoporosis (thin, weak bones) and lower the risk of fractures.
What is it used for?
- Osteoporosis in women after menopause
- Osteoporosis in men
- Bone loss caused by steroid medicines
How does it work?
Alendronate slows down the cells that break down bone. This lets bone-building cells catch up, making bones stronger.

- Jaw pain, swelling or loose teeth
- New pain in the thigh, hip or groin

If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
