What does it do?

Alendronic acid and colecalciferol is used to treat osteoporosis (weak bones). It helps to make your bones stronger and less likely to break.

Before you start

• Tell your doctor if you have kidney, parathyroid, dental or swallowing problems, or if you get heartburn or indigestion.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take the alendronic acid and colecalciferol tablet once a week, on the same day each week. Take it 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.

What if you forget a 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.

Can you take other medicines?

Some medicines available without a prescription may react with alendronic acid and colecalciferol including:

• calcium supplements (e.g. Calci-Tab®)
• iron supplements (e.g. Ferro-Tab®)
• antacids (e.g. Mylanta®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
