Overdose and Missed Dose

• Overdose of Clozapine can lead to serious complications, including severe sedation, delirium, and seizures. In such cases, it is crucial to contact a doctor immediately.

• If a dose of Clozapine has been missed, it should be taken as soon as remembered unless it's almost time for the next dose. Never double the dose.

Management of Side Effects

Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor.

• For sedation or dizziness, it is advised to take the medication at bedtime.

• Constipation can often be relieved by drinking plenty of water and eating a diet high in fibre.

• Hypersalivation may be managed by frequently rinsing the mouth with water.
