Frequently Asked Questions

Can I take a higher dose of Irbesartan if my symptoms don't improve?

No. Never increase the dose of Irbesartan without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.

What is the difference between an ACE inhibitor and an ARB?

Both block the renin-angiotensin system but at different points. ACE inhibitors prevent angiotensin II formation; ARBs block its receptor. ARBs do not cause the cough associated with ACE inhibitors, making them a preferred alternative in patients who cannot tolerate ACE inhibitor-induced cough.
