What this interaction means in plain words

Lithium and Romidepsin 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.

Evidence level: Low

Why it happens

Additive effects on cardiac repolarization.

What to do

Check an ECG at baseline and during treatment, and keep potassium and magnesium within normal range. Monitor lithium levels, particularly if chemotherapy causes vomiting or dehydration.
