Trental is used for treating intermittent claudication (pain, cramping, numbness, or weakness in the foot, hip, thigh, or buttocks) in certain patients. Trental is a xanthine derivative blood flow enhancer. It works by thinning the blood and improving red blood cell flexibility, causing the blood to flow more freely through the veins.
Use Trental as directed by your doctor.
- Take Trental by mouth with food or milk.
- Swallow whole. Do not break, crush, or chew before swallowing.
- If you miss a dose of Trental, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Trental.
Store Trental at room temperature, between 59 and 86 degrees F (15 and 30 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Trental out of the reach of children and away from pets.
