Summary

Benperidol is a butyrophenone antipsychotic that may prolong the QT interval, and formoterol can add to QT effects, particularly with hypokalemia. The legacy concern about sedation is not supported, but a QT interaction is plausible.

What this interaction means in plain words

Benperidol and Formoterol-mometasone 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.

Evidence level: Low

Why it happens

Additive effects on cardiac repolarization, with beta-2 agonist hypokalemia increasing risk.

What to do

Monitor ECG and electrolytes in patients with cardiac risk factors. Avoid adding other QT-prolonging drugs.
