Your medicine

Fosavance is used in post-menopausal women who have osteoporosis and are at risk of getting bone fractures.

In osteoporosis the strength of the bones is reduced and this can increase the chances of getting bone fractures. Fosavance can make bones stronger in people with osteoporosis which can reduce the chances of getting bone fractures.

It is very important that you take Fosavance correctly as it may lead to oesophageal problems if it is not taken in the right way. A member of your medical team will explain to you how to take Fosavance.
