Etidronate

et-ih-dron-ate

What does it do?

Etidronate 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.

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 etidronate as directed. You need to take it at least 2 hours before or after food or drink and other medicines. Etidronate 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.
Etidronate is usually taken for 2 weeks every 3 months.

What if you forget a dose?

Skip the missed dose and take the next day’s dose at the usual time.

Can you take other medicines?

Some medicines available without a prescription may react with etidronate 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.
