Last updated

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.

Summary

Both drugs can prolong the QT interval, and eliglustat exposure rises markedly in CYP2D6 poor metabolizers or with CYP2D6 inhibitors. Escitalopram is a weak CYP2D6 inhibitor and QT-prolonging, so the combination may raise arrhythmia risk.

What this interaction means in plain words

Eliglustat and Escitalopram 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.

Eliglustat belongs to Miscellaneous; Escitalopram belongs to Central Nervous System.

Evidence level: Moderate

Why it happens

Additive QT prolongation, with possible increase in eliglustat levels through weak CYP2D6 inhibition.

What to do

Avoid the combination where possible, particularly in CYP2D6 poor metabolizers or patients with cardiac disease. If used, obtain a baseline and follow-up ECG and correct electrolytes.
