I took Lisinopril for years, it was my first BP med.
It eventually stopped working, which is normal with BP meds.
I was on some other med for about a year and it stopped working.
I’m on Amlodipine and Metoprolol now.
Lisinopril made me dry cough so much I had to get two hernia repairs re-repaired. I stick to my Butchers Broom, now. No cough and works better.
