List of Medications


Pentoxifylline is a pharmacy drug with a variety of uses in medicine. Primarily, it is used to treat blood vessel problems and increase circulation, as well as to decrease associated symptoms such as pain, numbness, cramping, and tingling. Pentoxifylline works, simply, by thinning the blood, thus allowing it to flow with greater ease. Other medical uses for pentoxifylline include the following: high-altitude sickness, leg ulcers, diabetic neuropathy pain, eye disorders, ear disorders, strokes, and sickle cell disease.


Pentoxifylline is administered as an extended-release tablet to be taken orally several times per day as directed by your physician, though your compounding pharmacist can craft an alternative form of delivery if requested by your physician. Pentoxifylline is often taken for up to eight weeks, but your physician will decide the duration and dosage for you specifically, based on your condition, health, and age. Always follow your physician's directions precisely. If you have general questions about the drug, contact your compounding pharmacist and they will be happy to provide more information.
