Persantine

Persantine oral is used to stop blood clots from forming after heart valve replacement surgery.

Persantine injection is used in a test that measures how well your heart is pumping blood. This is sometimes referred to as a "stress test."

Persantine may also be used for other reasons that are not mentioned in this medication guide.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may change your dose from time to time. Use the medicine exactly as directed.
