Why is this medication prescribed?
Etidronate is used to treat Paget’s disease of bone (a condition in which the bones are soft and weak and may be deformed, painful, or easily broken) and to prevent and treat heterotopic ossification (growth of bone tissue in an area of the body other than the skeleton) in people who have had total hip replacement surgery (surgery to replace the hip joint with an artificial joint) or in people who have had an injury to the spinal cord. Etidronate is in a class of medications called bisphosphonates. It works by slowing the breakdown of old bone and the formation of new bone.
How should this medicine be used?
Etidronate comes as a tablet to take by mouth. It is usually taken once or twice a day on an empty stomach. To help you remember to take etidronate, take it at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take etidronate exactly as directed. Do not take more or less of it or take it more often or for a longer period of time than prescribed by your doctor.
You may swallow etidronate tablets with water or plain fruit juice. Do not swallow the tablets with milk, calcium fortified juice, or other drinks that contain calcium.
Do not eat for 2 hours before and 2 hours after you take etidronate. It is especially important not to eat or drink foods or drinks that are high in calcium such as milk for 2 hours before and after you take etidronate.
If you are taking etidronate to treat Paget’s disease of bone, it may take some time for your condition to improve. You may experience new or worsening bone pain, especially at the beginning of your treatment. Tell your doctor about any new or worsening symptoms you experience, but do not stop taking etidronate without talking to your doctor.
