TEGRETOL PLAIN is an immediate-release formulation of carbamazepine, an antiepileptic drug used to control seizures and manage neuropathic pain. Unlike controlled-release versions, this tablet releases the medication rapidly, requiring more frequent dosing (e.g., 2–4 times daily) to maintain therapeutic levels. It is a cost-effective option for patients who do not require extended-release therapy and is widely prescribed for generalized tonic-clonic seizures, focal seizures, and trigeminal neuralgia. Regular blood tests are recommended to monitor drug levels and liver function.
