lepsy. Gardenal Tablet is composed of Phenobarbitone as its main ingredient. It belongs to a group of medicines called barbiturates. Epilepsy is a neurological disorder characterised by sudden, frequent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain. Gardenal Tablet should be taken in dosage and duration as advised by your doctor. Your doctor will adjust or decrease your dose based on your condition.
