Summary
Sotalol is a potent QT-prolonging antiarrhythmic and ofloxacin may add to this effect. The combination raises the risk of torsades de pointes, especially with renal impairment, bradycardia or low electrolytes.
What this interaction means in plain words
Ofloxacin and Sotalol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Ofloxacin belongs to Anti Bacterial; Sotalol belongs to Cardiovascular.
Why it happens
Additive blockade of cardiac potassium channels with delayed repolarization.
What to do
Avoid the pairing and use a non-QT-prolonging antibiotic. If unavoidable, monitor ECG and correct potassium and magnesium before and during therapy.
