Summary
Telmisartan and olmesartan are both angiotensin receptor blockers, so using them together duplicates therapy. Dual RAS blockade increases the risk of hypotension, hyperkalemia and renal impairment without a proven added clinical benefit.
What this interaction means in plain words
Olmesartan and Telmisartan-amlodipine 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.
Olmesartan belongs to Cardiovascular; Telmisartan-amlodipine belongs to Cardiovascular.
Why it happens
Duplicate angiotensin II type 1 receptor blockade produces additive effects on blood pressure, aldosterone suppression and glomerular filtration.
What to do
Avoid combining two ARBs and use a single agent at an optimized dose. If both have been given, monitor potassium, creatinine and blood pressure and stop one.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
