Alendronic acid is used to treat osteoporosis (weak bones). It helps to make your bones stronger and less likely to break. It is also sometimes used for other conditions.
Take alendronic acid in the morning. You need to take it at least 30 minutes before food or drink and other medicines. Alendronic acid can damage your oesophagus (food pipe). To avoid this, take it with a large glass of water. Swallow the tablet whole, do not crush or chew it. Sit or stand upright for at least 30 minutes after taking a dose.
Weekly dose: Take the missed dose if you remember the next morning. If not, skip the dose and take the next week’s dose at the usual time.
Daily dose: Skip the missed dose and take the next day’s dose at the usual time.
Some medicines available without a prescription may react with alendronic acid including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
