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.
Etidronate may not work properly and may damage the esophagus (tube that connects the mouth and stomach) or cause sores in the mouth if it is not taken according to the following instructions. Tell your doctor if you do not understand, you do not think you will remember, or you are unable to follow these instructions:
- 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.
