Re: Lisinopril-HCTZ and salt substitutes?
All ACE inhibitors, including Lisinopril, can cause people to retain potassium. However, your other drug counters the effect because HCTZ depletes potassium.
Basically, talk to your doctor. I think that you can take eat bananas without a problem. Most people on Ace inhibitors do not have to monitor their potassium intake.
I take 5mg of Lisinopril each day and do not monitor my potassium intake. Granted, 5mg is a low dose of Lisinopril, but I do not think that I would have a potassium problem if I took a higher dose of Lisinopril. Your doctor probably will order blood tests to check your potassium levels anyways.
