Neuropin 100 Capsule is used to manage or prevent neuropathic pain and epilepsy. Besides this, it is also used to treat fibromyalgia and restless legs syndrome. It contains Gabapentin, which decreases the abnormal excitability of neurons (nerve cells) in the brain and helps in relieving nerve pain and lowers the risk of seizures. It may cause some side effects such as dizziness, drowsiness, fatigue, nausea, vomiting, fever, swelling, and ataxia (impaired balance or coordination). Before using this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and any pre-existing medical conditions.
