Summary
Fingolimod causes bradycardia on initiation and has been linked to QT effects, and ofloxacin may add to QT prolongation. The combination increases the risk of serious arrhythmia, especially during the first doses.
What this interaction means in plain words
Fingolimod and Ofloxacin 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.
Fingolimod belongs to Central Nervous System; Ofloxacin belongs to Anti Bacterial.
Why it happens
Additive QT prolongation combined with fingolimod-induced bradycardia, which favors torsades de pointes.
What to do
Avoid starting fingolimod while the patient is taking ofloxacin if possible. Where unavoidable, provide ECG monitoring during first-dose observation and correct electrolytes.
