Risedronate comes as a tablet and a delayed-release tablet to take by mouth. The delayed-release tablets are usually taken once a week in the morning, immediately after breakfast. The tablets are usually taken on an empty stomach once a day in the morning, once a week in the morning, once monthly in the morning, or once monthly for two mornings in a row depending on your condition and the dosage prescribed by your doctor. If you are taking risedronate once a week, once monthly, or once monthly for 2 days in a row, take it on the same day every week or month or the same 2 days in a row every month. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take risedronate 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.
Risedronate 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:
- You must take risedronate tablets immediately after you get out of bed in the morning and before you eat or drink anything. You must take risedronate delayed-release tablets immediately after breakfast. Never take risedronate at bedtime or before you wake up and get out of bed for the day.
- Swallow the tablets with a full glass (6 to 8 ounces [180 to 240 mL]) of plain water while you are sitting or standing. Swallow the delayed-release tablets with at least 4 ounces (120 mL) of plain water while you are sitting or standing. Never take risedronate with tea, coffee, juice, mineral water, milk, other dairy drinks, or any liquid other than plain water.
- Swallow the tablets and delayed-release tablets whole. Do not split, chew, or crush them. Do not suck on the tablets or hold them in your mouth for any length of time.
- After you take risedronate, do not eat, drink, or take any other medications for at least 30 minutes. Do not lie down for at least 30 minutes after you take risedronate. Sit upright or stand upright until at least 30 minutes have passed.
Risedronate controls osteoporosis and Paget's disease of bone but does not cure these conditions. Risedronate helps to treat and prevent osteoporosis only as long as it is taken regularly. Continue to take risedronate even if you feel well. Do not stop taking risedronate without talking to your doctor, but talk to your doctor from time to time about whether you still need to take risedronate.
