- swollen lymph glands
- swelling of your face
- unusual bruising or bleeding
- weakness, fatigue

Call your health care provider right away if you have:
- high fever, recurring fever, or long lasting fever

4. Like other antiepileptic drugs, ZONEGRAN may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

How can I watch for early symptoms of suicidal thoughts and actions?

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).
5. 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.
6. ZONEGRAN may cause problems with your concentration, attention, memory, thinking, speech, or language.
7. 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. Be sure to read the section titled “What are the possible side effects of ZONEGRAN?” |
