Readi-Cat 2 oral / rectal

Readi-Cat 2 is a contrast agent. This medicine works by coating the inside of your esophagus, stomach, or intestines which allows them to be seen more clearly on a CT scan or other radiologic (x-ray) examination.

Readi-Cat 2 is used to help diagnose certain disorders of the esophagus, stomach, or intestines.

Readi-Cat 2 may also be used for purposes not listed in this medication guide.
