Both agents have been linked with QT prolongation, so combined use may add to the risk of torsades de pointes. The risk rises with electrolyte disturbance, heart disease or other QT-prolonging drugs.
What this interaction means in plain words
Gemtuzumab and Paliperidone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive prolongation of cardiac repolarization; the mechanism for gemtuzumab is not well characterized.
What to do
Check ECG and electrolytes before and during treatment and correct potassium and magnesium deficits. Consider an alternative antipsychotic if the QTc becomes markedly prolonged.
