1. WHAT ALENDRONIC ACID 70MG TABLETS ARE AND WHAT THEY ARE USED FOR
Alendronic acid belongs to a group of non-hormonal medicines known as bisphosphonates, which prevent bone loss from the body.
Alendronic acid is used to treat a condition called osteoporosis (brittle bones). This condition is common in women after the menopause. The earlier a woman reaches the menopause, the greater the risk of her developing osteoporosis.
Without treatment, osteoporosis can cause thinning and weakening of the bones in the skeleton which can then lead to fractures, usually of the hip, backbone and wrists. Fractures can occur easily in people suffering from osteoporosis including during normal everyday activities such as heavy lifting or from a minor injury or fall.
Alendronic acid helps to prevent bone loss and to build up bone which may have been lost due to osteoporosis. It can therefore reduce the risk of back and hip fractures.
