GABAPEN 100 MG contains Gabapentin and is primarily used to manage neuropathic pain caused by nerve damage from conditions like diabetes, shingles, or spinal cord injury, and as an add-on treatment to control certain types of seizures in adults and children over 6 years old. 1 It works by reducing abnormal electrical activity in the brain and interfering with pain signals traveling through damaged nerves. Common side effects may include dizziness, drowsiness, fatigue, and impaired coordination, and it should be used with caution in individuals with kidney problems. 2
