Patient Education

Pregabalin


Pregabalin capsules, oral solution (liquid), and extended-release (long-acting) tablets are used to relieve neuropathic pain (pain from damaged nerves) that can occur in your arms, hands, fingers, legs, feet, or toes if you have diabetes and postherpetic neuralgia (PHN; the burning, stabbing pain or aches that may last for months or years after an attack of shingles). Pregabalin capsules and oral solution are also used to relieve neuropathic pain that can occur after a spinal cord injury and to treat fibromyalgia (a long-lasting condition that may cause pain, muscle stiffness and tenderness, tiredness, and difficulty falling asleep or staying asleep). Pregabalin capsules and oral solution are used along with other medications to treat certain types of seizures in adults and children 1 month of age and older. Pregabalin is in a class of medications called anticonvulsants. It works by decreasing the number of pain signals that are sent out by damaged nerves in the body.
