What is the most important information I should know about etidronate (Didronel)?
Take etidronate with a full glass (6 to 8 ounces) of water. Use only plain water (not mineral water) when taking an etidronate tablet.
For at least the first 2 hours after taking etidronate, do not eat or drink anything other than plain water, and do not take any other medicines including vitamins or mineral supplements.
Especially avoid drinking milk or eating dairy products within 2 hours after taking etidronate. Also avoid taking supplements that contain calcium, magnesium, iron, or aluminum (such as in multivitamins with iron, and in many types of antacids).
Some people using medicines similar to etidronate have developed bone loss in the jaw, also called osteonecrosis of the jaw. Symptoms may include jaw pain, swelling, numbness, loose teeth, gum infection, or slow healing after injury or surgery involving the gums. You may be more likely to develop osteonecrosis of the jaw if you have cancer or have been treated with chemotherapy, radiation, or steroids. Other conditions associated with osteonecrosis of the jaw include blood clotting disorders, anemia (low red blood cells), and a pre existing dental problem.
If you need to have any dental work (especially surgery), tell the dentist ahead of time that you are using etidronate. You may need to stop using the medicine for a short time.
Talk with your doctor about the risks and benefits of using this medication.
