ACE inhibitor and kidney function

Written by: Dr. Rowena | Posted: Sep 23 2009

Q: I just had my blood screening and my potassium is 5.2 mmol/l. It exceeds the normal range 3.5-5.0 mmol/l. My doctor prescribed Perindopril Erbumine 4 mg/per day for me. Does the increased potassium in my blood affect my kidneys?

A: The drug you are on is used to treat high blood pressure. It is in the category known as an angiotensin-converting enzyme (ACE) inhibitor. The drug can cause an increase in blood potassium levels and hurt the kidneys. Since your doctor is checking your blood levels, it is likely your kidney function is being closely monitored. You should discuss this further with your doctor.
