Summary
Androgen deprivation with triptorelin can prolong the QT interval, and levofloxacin has similar effects. Together they may increase the risk of torsades de pointes, especially with electrolyte disturbances or heart disease.
What this interaction means in plain words
Levofloxacin and Triptorelin 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.
Levofloxacin belongs to Anti Bacterial; Triptorelin belongs to Endocrine.
Why it happens
Additive QT prolongation, with androgen deprivation altering cardiac repolarization and levofloxacin blocking potassium channels.
What to do
Review ECG and electrolytes before and during co-administration, correcting potassium and magnesium. Consider a non-QT-prolonging antibiotic in patients with other risk factors.
