NB Biolevetam 500 Tablet is an anticonvulsant medicine used for the treatment of epilepsy and certain types of seizures. It works by stabilizing electrical activity in the brain and preventing sudden abnormal nerve signals that cause convulsions. In addition to epilepsy, it may be prescribed for neuropathic pain and mood-related symptoms associated with nervous system disorders. The tablet contains Levetiracetam as its active ingredient, which is well tolerated and effective in controlling seizures when taken regularly. Patients should take the medicine exactly as prescribed, at the same time each day, and should not stop suddenly without consulting their doctor, as this may increase the risk of breakthrough seizures. Common side effects include dizziness, drowsiness, fatigue, decreased appetite, headache, and mild behavioral changes. Rarely, mood disturbances, irritability, or aggression may occur, requiring medical advice. Alcohol should be avoided, as it increases the risk of drowsiness and impairs alertness. Pregnant and breastfeeding women should consult their doctor before use. Patients with kidney or liver disease may require dose adjustments. With consistent use under medical supervision, NB Biolevetam 500 helps restore neurological stability, reduce seizure frequency, and improve quality of life in affected patients.
