Pregabalin is an anticonvulsant drug that is used to relieve neuropathic pain that results from damaged nerves. This pain occurs in your arms, fingers hands, legs, toes or feet. It is also used to treat fibromyalgia, which is a long-lasting condition that causes pain, tiredness, muscle tenderness and stiffness, and difficulty staying asleep. Pregabalin is also used to help treat various types of seizure in people with epilepsy. Pregabalin works by reducing the amount of pain signals sent out by damaged nerves inside the body.
