  • What is Peganone?

    Peganone is a drug used to control tonic-clonic (grand mal) and complex partial (psychomotor) seizures.

    Tonic-clonic seizures are a type of seizure in which the individual experiences a sudden loss of consciousness immediately followed by generalized convulsions. Complex partial seizures are characterized by blank staring and repetitive movements. Peganone works by slowing down impulses in the brain that cause seizures.

  • What is the most important information I should know about Peganone?

    Do not change the brand, generic formulation, or dosage of this medication without first talking to your doctor. If you have been taking Peganone regularly to prevent major seizures, do not stop abruptly. This may precipitate prolonged or repeated epileptic seizures without any recovery of consciousness between attacks—a condition called status epilepticus—that can be fatal if not treated promptly.

    Blood abnormalities have occurred in some patients taking Peganone, although it is unknown whether the drug was the cause. Your doctor will do monthly blood tests when you first start therapy to guard against any such problems. Call your doctor immediately if you have symptoms such as sore throat, fever, malaise (marked by bodily discomfort, fatigue, or a general feeling of illness), easy bruising, small purple skin spots, nosebleeds, or any sign of infection or bleeding tendency.

    Because Peganone may cause gum hypertrophy (excessive formation of the gums over the teeth), it's important to practice good dental hygiene while taking Peganone.
