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.
Etidronate comes as a tablet to take by mouth. It is usually taken once a day on an empty stomach. Treatment for Paget's disease may be repeated if symptoms come back or worsen after some time has passed. Take etidronate 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.
Swallow the tablets with a full glass (6 to 8 ounces [180 to 240 mL]) of plain water while you are sitting or standing.
Sit or stand upright after taking etidronate.
Do not eat, drink, or take any other medications (including vitamins or antacids) for 2 hours before and 2 hours after you take etidronate.
If you are taking etidronate to treat Paget's disease of bone or to prevent or treat heterotopic ossification, it may take some time for your condition to improve. Do not stop taking etidronate without talking to your doctor.
Etidronate is also used sometimes to treat and prevent osteoporosis (condition in which the bones become thin and weak and may break easily) caused by corticosteroids (a type of medication that may cause osteoporosis). Talk to your doctor about the possible risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
It is important that you get enough calcium and vitamin D and eat a balanced diet while you are taking etidronate. Your doctor will tell you which foods are good sources of these nutrients and how many servings you need each day. If you find it difficult to eat enough of these foods, tell your doctor. In that case, your doctor may prescribe or recommend a supplement.
If you have not already eaten, take the missed dose as soon as you remember it. If you have already eaten, take the missed dose 2 hours after you last ate. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
