Pentanerv Grds 450 Tablet 10's is used to manage or prevent neuropathic pain and epilepsy. Besides this, it is also used to treat fibromyalgia(a condition that causes body-wide pain and fatigue) and restless legs syndrome (a strong urge to move the legs, usually at night). Pentanerv Grds 450 Tablet 10's contains Gabapentin, which works by calming overactive nerve signals in the brain. This helps reduce nerve pain and lowers the risk of seizures. It may cause some side effects in some individuals, 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.
