Duration for the use of Pregabalin depends on the condition for which you are taking this medicine. If you are taking it for epilepsy, and it is effectively helping you then, you may have to continue it for years. If you are taking it for neuropathic or fibromyalgia pain, it is likely that once your symptoms improve you will have to continue taking it for several months. This will ensure that the problem does not come back. It is advised not to stop taking this medicine without consulting your doctor.
