Patient Medicine Information
Why do I need this medicine?

This medicine is also used to treat Paget's disease (a painful bone condition which can cause abnormal bone growth and deformity). Risedronic Acid helps to regulate the growth of bone in Paget's disease.
How do I take this medicine?
Take Risedronic Acid exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

Take Risedronic Acid first thing in the morning, upon arising for the day. Take it with a full glass of plain water on an empty stomach, at least 30 minutes before the first drink or food of the day. Swallow it whole. Do not suck, chew or crush it.

To prevent irritating the throat, take it in a sitting or standing position. Do not take at bedtime or while lying down and do not lie down for at least half an hour after swallowing it. Do not swallow it while lying down. Do not lie down for at least 30 minutes after taking it. Do not eat or drink anything except plain water during this 30 minutes.
