Trental ER, known as pentoxifylline ER, is a medication used for various purposes.

Pentoxifylline can decrease the muscle aching/pain/cramps during exercise, including walking, that occur with intermittent claudication.

Use and Dosage

Take this medication by mouth with food as directed by your doctor, usually 3 times daily.

Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release the entire drug at once, increasing the risk of side effects.

Dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Keep taking this medication even if you feel well. Do not stop this medication without consulting your doctor. Improvement in symptoms can occur in 2-4 weeks, but it may take up to 8 weeks to get the full benefit.

Tell your doctor if your condition lasts or gets worse.
