Olmesartan is an angiotensin-receptor blocker (ARB), a class of medication commonly prescribed to lower blood pressure and actually help protect the kidneys in people with kidney disease — not harm them.

That said, ARBs can raise potassium levels in the blood, a condition called hyperkalemia (too much potassium). This happens because ARBs reduce a hormone called aldosterone, which normally helps your kidneys remove excess potassium. Here are some things to watch for if taking an ARB like Olmesartan:

- Hyperkalemia symptoms — muscle weakness, tingling, chest pain, or irregular heartbeat
- Regular blood tests — your doctor should monitor your potassium and kidney function
- Tell your doctor about all other medications and supplements you're taking

The good news is that ARBs are generally considered a kidney-friendly option for managing high blood pressure. Always check with your nephrologist or doctor if you have concerns about how any medication is affecting your kidneys.
