  • If you have a history of a clinically significant low white blood cell or drug induced leukopenia/neutropenia (low white blood cell), you should have your complete blood count (CBC) monitored frequently during the first few months of therapy.
  • Use with caution if you are receiving anticonvulsant medication, with a history of seizures, or with EEG abnormalities.
  • Your blood electrolyte level (magnesium, potassium) should be regularly monitored.
  • Inform your doctor if you have heart problems or a history of irregular heartbeat, liver or kidney problems, a bowel obstruction, an enlarged prostate, or glaucoma, severe diarrhea, difficulty urinating, or high or low blood pressure.
  • Do not change your dose or stop taking pimozide, even if you are feeling well, as this may worsen your symptoms.
  • Use of pimozide may cause drowsiness, dizziness, or blurred vision; it is advisable to avoid driving or operating heavy machinery under such circumstances till you feel fine.
