Pentoxifylline
About Pentoxifylline
Pentoxifylline belongs to a class of medicines called Hemorrheologic agents (affects blood viscosity), primarily used to treat pain in the legs due to insufficient blood flow (intermittent claudication). It also reduces cramping, numbness, or weakness in the legs on walking in such patients. Intermittent claudication is a peripheral vascular disease in which you have cramp-like pain in your legs when you walk and is caused by an insufficient blood supply in your legs.
Pentoxifylline works by decreasing the viscosity (thickness) of blood, allowing it to pass more easily through the blood vessels, especially in the small blood vessels of the hands and feet. It can also increase the distance you can walk without pain since it improves your legs' blood circulation. It is recommended in patients whose pain has not improved even after lifestyle changes like quitting smoking and doing regular exercise.
Pentoxifylline should be taken regularly in dose and duration as advised by the doctor. Your doctor will advise you on the exact dosage and how often you have to take Pentoxifylline based on your medical condition. You may experience nausea, vomiting, diarrhoea, headache, lightheadedness, sleep problems, intrahepatic cholestasis (removal of bile from the liver is blocked), abdomen pain, constipation, and urine discolouration in some cases. Most of these side effects of Pentoxifylline do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.
Pentoxifylline should not be stopped abruptly without consulting the doctor as it may lead to unpleasant side effects. Inform your doctor before starting Pentoxifylline if you have any kidney or liver disease or plan to become pregnant, or are breastfeeding. Also, lifestyle changes should be continued with Pentoxifylline for best results. Do not take Pentoxifylline if you ever had bleeding in your brain or the retina of your eyes, heart failure, chest pain, heart disease, and blood pressure.
