Summary
Lofexidine prolongs the QT interval and slows heart rate, while high-dose albuterol can cause hypokalemia and tachyarrhythmias with modest QT effects. Together they may increase proarrhythmic risk, particularly with electrolyte disturbance.
What this interaction means in plain words
Albuterol and Lofexidine 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 QT prolongation, with beta-agonist induced hypokalemia adding to torsade risk.
What to do
Monitor ECG and potassium in patients with additional risk factors, and use the lowest effective albuterol dose.
