Who can take alendronic acid
Most adults can take alendronic acid. Children who have osteoporosis can sometimes take it if it's been prescribed for them by a specialist doctor.
Who may not be able to take alendronic acid
Alendronic acid is not suitable for some people. Check with your doctor or pharmacist before starting to take it if you:
- have ever had an allergic reaction to alendronic acid or any other medicine
- have problems digesting food, swallowing or other problems with your food pipe (oesophagus)
- have taken alendronic acid before but it made you feel dizzy
- are unable to stand or sit upright for at least 30 minutes after taking it
- have low calcium levels in your blood – alendronic acid sometimes causes low blood calcium, so your calcium levels could become even lower
- have kidney problems
- have cancer, or are having chemotherapy or radiotherapy
- have problems with your teeth, or are waiting for dental treatment such as having a tooth out
- smoke, or used to smoke – this may increase your risk of dental problems
