Summary
Indapamide can cause hypokalemia and hypomagnesemia and has been associated with QT prolongation. These disturbances increase the arrhythmic risk of dolasetron, which itself prolongs QT and QRS intervals.
What this interaction means in plain words
Dolasetron and Indapamide 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.
Dolasetron belongs to Gastrointestinal Tract; Indapamide belongs to Cardiovascular.
Why it happens
Additive QT effects, with diuretic-induced electrolyte depletion increasing proarrhythmic susceptibility.
What to do
Check and correct potassium and magnesium before and during dolasetron use. Choose another antiemetic when electrolytes cannot be kept normal.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
