What is Alendronic Acid?
Alendronic Acid is a bisphosphonate, a type of medicine that binds to calcium in bones. Bisphosphonates prevent the breakdown of bone and make bone stronger. Alendronic Acid is a prescription-only medicine.
What is this medicine used for?
Alendronic Acid is used to treat osteoporosis, a condition in which there is more breakdown of bone than formation. Hence the bones become thinner and can break more easily. Osteoporosis can also cause the vertebra to collapse. Osteoporosis usually occurs in older women due to menopause, but younger women and men may also be affected. The female sex hormone oestrogen plays a role in, amongst other things, maintaining the balance between bone breakdown and renewal. When oestrogen levels drop during menopause this balance is disrupted which, in turn, can lead to osteoporosis.
How to use Alendronic Acid
Alendronic Acid is available in tablet form and comes in two strengths of 10 mg and 70 mg. The 10 mg tablet is for daily use and the 70-mg tablet is for weekly use. When Alendronic Acid is taken by mouth it can cause irritation and ulceration of the oesophagus. To minimise this risk, do not take the tablet while lying down. Swallow the tablet with a full glass of water in the morning after getting up, at least 30 minutes before the first food or drink of the day. You should not eat or drink anything or lie down for at least 30 minutes after taking the tablet. You can lie down after 30 minutes, but only if you have had something to eat.
Unless otherwise advised by a doctor, the usual dose in adults is:
- one 10-mg tablet once a day or one 70-mg once a week.
Alendronic Acid is not suitable for children under the age of 18. Always follow the prescription exactly - never use more or less than the doctor recommends. Read the package leaflet before use.
