Summary
Squill contains cardiac glycosides, and hydrochlorothiazide-induced hypokalemia and hypomagnesemia increase the risk of glycoside toxicity and arrhythmias.
What this interaction means in plain words
Amlodipine-olmesartan-hydrochlorothiazide and Squill 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
Diuretic-induced potassium and magnesium depletion sensitizes the myocardium to cardiac glycoside effects.
What to do
Avoid squill preparations in patients on thiazides. If used, monitor potassium and magnesium and ECG, and correct deficits.

- Does the benefit of taking both outweigh the risk in my case?
