Why is this medication prescribed?
Pentoxifylline is used to improve blood flow in patients with circulation problems to reduce aching, cramping, and tiredness in the hands and feet. It works by decreasing the thickness (viscosity) of blood. This change allows your blood to flow more easily, especially in the small blood vessels of the hands and feet.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Pentoxifylline comes as an extended-release (long-acting) tablet to take by mouth. It usually is taken three times a day. Do not break, crush, or chew the tablets; swallow them whole. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take pentoxifylline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Although you may feel the effects of this medication in 2-4 weeks, you may need to take it for up to 8 weeks before you feel the full effect of pentoxifylline.
Pentoxifylline controls the symptoms of circulation problems, but does not cure them. Continue to take pentoxifylline even if you feel well. Do not stop taking pentoxifylline without talking to your doctor.
