Do you sometimes feel a tingling or aching sensation in your legs, especially when you walk a short distance or climb stairs? The reason for this may be poor blood flow to the legs, that is, poor blood circulation . So today we are going to talk about a special medicine that doctors recommend for this kind of condition. That is Pentoxifylline. You may see this medicine under brand names like Trental and Pentopak.
What really happens with this medicine?
Simply put, this medicine called Pentoxifylline works by improving blood circulation in your body, especially in the blood vessels of your legs.
Imagine a water pipe that is a little clogged. It's hard for water to flow, isn't it? That's how blood flow in the blood vessels is disrupted. This medicine helps the blood cells become more flexible. Then they can move more easily through the small, clogged blood vessels. As the blood supply to the legs increases, the pain, numbness, and discomfort you feel gradually decrease.
The most important thing is that this medicine should be used only on medical advice . Sometimes the doctor may prescribe this medicine for other medical conditions as well. So always listen to what your doctor says.
Things you need to tell your doctor before taking medicine
It is very important that your doctor is fully aware of your health condition before giving you Pentoxifylline. Therefore, if you have any of the following, be sure to tell your doctor.
