What this interaction means in plain words
Hydrochlorothiazide-irbesartan and Sodium sulfate / potassium sulfate / magnesium sulfate 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

Consider withholding the diuretic and ARB combination on the day of bowel preparation, encourage fluid intake, and check electrolytes and creatinine in high-risk patients.
