Syncope, presyncope, palpitations, dizziness, or ECG QTc prolongation
QTc >500 ms, torsades, sudden death risk. Risk from: multiple QT drugs, low K+/Mg2+, bradycardia, congenital predisposition, structural heart disease.
Temporal association with antipsychotic initiation, dose change, or depot timing.
Separates the Medication Side Effects / Iatrogenic Toxicity / QT Risk group. It is not specific to QT prolongation risk state.
Applies to the Medication Side Effects / Iatrogenic Toxicity / QT Risk group — not specific to QT prolongation risk state
Rows marked “Whole group”: Applies to the Medication Side Effects / Iatrogenic Toxicity / QT Risk group — not specific to QT prolongation risk state

Constipation with clozapine is a red flag, not a nuisance side effect Clozapine constipation and myocarditis are high-risk problems Escalate early, review bowels deliberately, maintain active surveillance during early titration Early activation is a common misread Clinical toxicity can occur even when history suggests a "usual dose" Check ammonia if unexplained confusion develops on valproate
Applies to the Medication Side Effects / Iatrogenic Toxicity / QT Risk group.
ECG / QT assessment, Urea, electrolytes, creatinine, Inflammatory markers (CRP/ESR), Creatine kinase
