PRESCRIBED FOR: Pentoxifylline is used for the treatment of intermittent claudication caused by peripheral arterial disease.

DOSING: The recommended dose of pentoxifylline is 400 mg three times daily with meals. The dose may be reduced to 400 mg twice daily to reduce adverse effects.

DRUG INTERACTIONS: Pentoxifylline reduces the breakdown of theophylline (Theo-Dur, Respbid, Slo-Bid, Theo-24, Theolair, Uniphyl, Slo-Phyllin) in the liver, increasing blood levels and side effects of theophylline. Combining pentoxifylline with warfarin (Coumadin) may increase the risk of bleeding. The mechanism for this interaction is unknown.

NURSING MOTHERS: Pentoxifylline is excreted in breast milk and may cause adverse effects in the infant.
