Summary

What this interaction means in plain words
Fingolimod and Risperidone 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.

Why it happens
Additive QT prolongation, with fingolimod-induced bradycardia increasing the risk of torsades de pointes.
What to do
Perform a baseline ECG and extended first-dose cardiac monitoring, and seek cardiology advice before starting fingolimod in patients on QT-prolonging drugs. Consider alternative multiple sclerosis therapy if QT risk is high.
