I never had high blood pressure until I started taking abiraterone. Within a few months, my blood pressure went up so they started me on a couple of different blood pressure medicines. By the time I had stopped taking abiraterone, 2 1/2 years later, I was on a third blood pressure medication. Since I stopped abiraterone I have reduced one of the drugs in half, the high blood pressure has stayed with me, but with the pills it’s actually pretty low 92/49 on Tuesday, but it’s usually in the low 60’s maybe 100/60 average. I went in a few months ago to get minor surgery to remove a cyst. They took my blood pressure and it was 86/48, I think that was below what they were allowed, to do surgery. I had no symptoms of low blood pressure, checking a second time showed it was only slightly higher. After the procedure completed, I checked the notes to see what they had to say, My blood pressure was listed higher than it actually was, in the notes.

This has happened with other people as well, A common problem.

The other issue I had was that abiraterone brought back my ancient history afib. I had 2 afib events, one in 2004 and another in 2006 then in 2021, 10 months after starting abiraterone, I had a third. Two more happened before my oncologist pulled me off abiraterone 2.5 years later. No problem while on Darolutamide for 20 months.

Depending on the heart issues, some doctors may not prescribe abiraterone.
