Clozapine — FY prescribing 🚨 💊
Clozapine interruption: high-risk restart
- NHS SPS advises that if more than 48 hours have elapsed since the last dose, specialist-guided re-titration is required; restarting the established maintenance dose can precipitate serious cardiovascular or neurological harm.
- Check exact time of last administration, brand and dispensing/monitoring service, swallowing route, infection and smoking changes.
- Contact mental health pharmacy or clozapine team urgently about re-titration, blood monitoring and continuity of supply; document the agreed plan.

Clozapine — FY prescribing 🚨 💊
⚠️ Editorial teaching card; not a prescribing instruction. Confirm current BNF/BNFC, SmPC, local formulary and specialist advice for any dose, route or formulation. Independent pharmacist sign-off pending.
🧬 Pharmacology and role
Specialist antipsychotic in treatment-resistant schizophrenia; associated with neutropenia/agranulocytosis, myocarditis, seizures and severe constipation.
🔎 Before giving
- Confirm the approved clozapine blood-monitoring and dispensing system, current result, actual prescription and last dose.
- If doses have been interrupted, do not simply restart the prior full dose: seek specialist re-titration advice.
- Assess fever/infection, chest pain, tachycardia and bowel movements, including ileus/red-flag symptoms.
🚨 Avoidable error / escalation
Clozapine is time-critical but specialist-controlled; restarting without confirming an interruption and safety checks can cause severe hypotension and collapse.
