What is alendronate used for?

What conditions is alendronate used to treat?

Alendronate is a bisphosphonate used to prevent and treat bone loss. It’s prescribed for people with osteoporosis, including cases where bones are weak because of age or menopause. It can also be used to treat osteoporosis in men.[1]

How is alendronate used for prevention vs. treatment?

Alendronate may be used either to reduce the risk of fractures in people with osteoporosis or to treat osteoporosis that has already caused significant bone density loss.[1]

Is alendronate used for anything besides osteoporosis?

Yes. It can also be used to treat Paget’s disease of bone (a disorder that causes abnormal and often enlarged bone). [1]

How does it work (and why that matters for its uses)?

Alendronate slows bone breakdown. By reducing bone resorption, it helps maintain or increase bone mineral density, which is why it’s used to lower fracture risk in osteoporosis and to manage abnormal bone turnover in Paget’s disease.[1]

Important patient-use note

Alendronate is commonly taken with specific instructions (such as remaining upright for a period after taking a dose) to help reduce the risk of irritation to the esophagus. People prescribed it should follow their clinician’s directions and the label instructions.[1]
