Risedronate has other uses, too, like treating Paget's disease of bone. You should take risedronate exactly how your doctor tells you. You must swallow the tablet whole. It is very important to take your dose right when you wake up, on an empty stomach and with a full glass of water. After you take your dose, you must wait at least 30 minutes - before you lie down - before you take other medicines - and before you eat or drink anything except plain water. You should read the Instructions for Use for full information. Most people tolerate this medicine well. Common side effects include heartburn, pain in the stomach area, and minor pain in the muscles, bones or joints. These effects are normal if they are mild and should go away.
