Neurontin (generic name gabapentin) is one of the best anticonvulsant drugs. Its active use in the treatment of epilepsy helps many people whose lives are complicated by this disease. Neurontin helps control epileptic seizures. It is available in capsules, tablets and liquid forms. Neurontin interacts with calcium channels in the brain, reducing the abnormal electrical activity that causes seizures. It can be used in combination with other antiepileptic drugs or as monotherapy in adults and children. Neurontin is often prescribed for partial and generalized tonic-clonic seizures. Neurontin is actively used to treat neuropathic pain that is not treatable with conventional painkillers. It is often prescribed off-label to help manage nerve pain associated with shingles, diabetes, spinal cord injury, fibromyalgia and more.
