This is a prescription medicine requiring mandatory regular blood tests to monitor white blood cells, because clozapine can rarely cause a serious drop in infection-fighting cells (agranulocytosis). Seek urgent care for fever, sore throat, mouth ulcers or flu-like illness. Also seek urgent help for chest pain, palpitations, breathlessness, severe constipation, drooling with fever, or seizures. Avoid alcohol; it can cause drowsiness. Do not drive until you know how it affects you. Tell your doctor about all other medicines and if you smoke. Avoid in pregnancy/breastfeeding unless advised. Store in a cool, dry place. This product information is for general guidance only and does not replace professional medical advice. Always consult a qualified healthcare provider before starting any new medication. Keep all medicines out of reach of children.
