Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using risedronate and each time you get a refill. Follow the instructions very closely to make sure you absorb as much of the drug as possible and reduce the risk of injury to your esophagus. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once a day. Take it after getting up for the day and before taking your first food, beverage or other medication. Do not take it at bedtime or while you are still in bed.

Take this medication with a full glass of plain water (6 to 8 ounces or 180 to 240 milliliters). Do not take it with any other beverage. Swallow the tablet whole. Do not chew or suck on it. Then stay fully upright (sitting, standing or walking) for at least 30 minutes, and do not lie down until after your first food of the day. Wait at least 30 minutes after taking risedronate before you eat or drink anything other than plain water and before taking any other medication by mouth.

Calcium or iron supplements, vitamins with minerals, antacids containing calcium/magnesium/aluminum, dairy products (such as milk, yogurt), and calcium-enriched juice may interfere with absorption of risedronate. Medications such as quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), sucralfate, and bismuth subsalicylate may also interfere with absorption. Do not take these products for at least 30 minutes after taking risedronate.

Use this medication regularly in order to get the most benefit from it. Remember to take it at the same time each morning. Talk to your doctor about the risks and benefits of long-term use of this medication.
