Contents of the pack
What is FOSAMAX Weekly?
FOSAMAX Weekly is a tablet that contains the active substance alendronic acid (commonly called alendronate) and belongs to a group of non-hormonal medicines called bisphosphonates. FOSAMAX Weekly prevents bone loss in women after menopause and helps to rebuild bone. FOSAMAX Weekly reduces the risk of spine and hip fractures.
What is FOSAMAX Weekly used for?
Your doctor has prescribed FOSAMAX Weekly to treat your osteoporosis. It reduces the risk of spine and hip fractures.
FOSAMAX Weekly is a weekly treatment.
What is osteoporosis?
Osteoporosis is a thinning and weakening of the bones. It is common in women after menopause. During menopause, the ovaries stop producing the female hormone, estrogen, which helps to keep a woman's skeleton healthy. As a result, bone loss occurs and the bones become weaker. The earlier a woman reaches menopause, the greater her risk of osteoporosis.
For a long time, osteoporosis usually has no symptoms. However, if left untreated, it can result in broken bones. Although these usually hurt, spine fractures can go unnoticed until they cause a loss of height. Bones can break during normal daily activity, such as when getting up or from minor injuries that would not normally break a bone. Fractures usually occur in the hip, spine, or wrist and can cause not only pain but also serious problems such as a stooped back (dowager's hump) and loss of mobility.
How can osteoporosis be treated?
As well as your treatment with FOSAMAX Weekly, your doctor may suggest that you make changes to your lifestyle to help your condition, such as:
Stopping smokingSmoking appears to increase the rate at which you lose bone and may therefore increase your risk of broken bones.
ExerciseLike muscles, bones need exercise to stay strong and healthy. Consult your doctor before starting any exercise program.
Eating a balanced dietYour doctor may advise you on your diet or whether you should take any food supplements (especially calcium and vitamin D).
Do not take FOSAMAX Weekly
If you think any of these apply to you, do not take the tablets. Talk to your doctor first and follow their advice.
