Zonegran Precautions

Zonegran may cause serious side effects, including:

  1. Serious skin rash that can cause death.
  2. Less sweating and increase in your body temperature (fever).
  3. Suicidal thoughts or actions in some people.
  4. Increased level of acid in your blood (metabolic acidosis).
  5. Problems with your concentration, attention, memory, thinking, speech, or language.
  6. Blood cell changes such as reduced red and white blood cell counts.

These serious side effects are described below.

  1. Zonegran may cause a serious skin rash that can cause death. These serious skin reactions are more likely to happen when you begin taking Zonegran within the first 4 months of treatment but may occur at later times.
  2. Zonegran may cause you to sweat less and to increase your body temperature (fever). You may need to be hospitalized for this. You should watch for decreased sweating and fever, especially when it is hot and especially in children taking Zonegran.
    Call your health care provider right away if you have:
    • a skin rash
    • high fever, recurring fever, or long lasting fever
    • less sweat than normal
  3. Like other antiepileptic drugs, Zonegran may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.
    Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:
    • thoughts about suicide or dying
    • attempt to commit suicide
    • new or worse depression
    • new or worse anxiety
    • feeling agitated or restless
    • panic attacks
    • trouble sleeping (insomnia)
    • new or worse irritability
    • acting aggressive, being angry, or violent
    • acting on dangerous impulses
    • an extreme increase in activity and talking (mania)
    • other unusual changes in behavior or mood
    • Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.
    How to watch for early symptoms of suicidal thoughts and actions:
    • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
    • Keep all follow-up visits with your healthcare provider as scheduled.
    Call your healthcare provider between visits as needed, especially if you are worried about symptoms.
    Do not stop Zonegran without first talking to a healthcare provider.
    Stopping Zonegran suddenly can cause serious problems. Stopping a seizure medicine suddenly in a patient who has epilepsy can cause seizures that will not stop (status epilepticus).
  4. Zonegran can increase the level of acid in your blood (metabolic acidosis). If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones and can slow the rate of growth in children. Metabolic acidosis can happen with or without symptoms.
    Sometimes people with metabolic acidosis will:
    • feel tired
    • not feel hungry (loss of appetite)
    • feel changes in heartbeat
    • have trouble thinking clearly
    Your healthcare provider should do a blood test to measure the level of acid in your blood before and during your treatment with Zonegran.
  5. Zonegran may cause problems with your concentration, attention, memory, thinking, speech, or language.
  6. Zonegran can cause blood cell changes such as reduced red and white blood cell counts. Call your healthcare provider if you develop fever, sore throat, sores in your mouth, or unusual bruising.

Zonegran can have other serious side effects. For more information ask your healthcare provider or pharmacist. Tell your healthcare provider if you have any side effect that bothers you.

  • Do not take Zonegran if you are allergic to medicines that contain sulfa.
  • Do not drink alcohol or take other drugs that make you sleepy or dizzy while taking Zonegran until you talk to your health care provider. Zonegran taken with alcohol or drugs that cause sleepiness or dizziness may make your sleepiness or dizziness worse.
  • Do not drive, operate heavy machinery, or do other dangerous activities until you know how Zonegran affects you. Zonegran can slow your thinking and motor skills.

Grapefruit and grapefruit juice may interact with Zonegran and lead to potentially dangerous effects. Discuss the use of grapefruit products with your healthcare provider.
