Zen Retard 400 Tablet is an antiepileptic and nerve pain medicine used to manage epilepsy (seizures) and trigeminal neuralgia, a severe facial nerve pain condition. It works by reducing abnormal electrical activity in brain and nerve cells, controlling seizure frequency and nerve pain.
It contains carbamazepine in a sustained-release formulation. Take it with food as prescribed by your doctor at regular intervals. Do not crush or chew the prolonged-release tablet, and do not stop taking it abruptly as this may trigger rebound seizures.
Establishing safe daily habits supports epilepsy management. Ensuring regular sleep patterns, managing stress, avoiding excessive alcohol, and staying well-hydrated help maintain consistent nerve stability alongside medicine.
Before starting this medicine, inform your doctor if you have blood disorders, heart conditions, liver problems, or a history of medicine allergies. Inform your doctor immediately if you develop a fever, persistent sore throat, unusual bruising, or a spreading skin rash.
