My father is currently on Zytiga for a bit more than 3 months and a half and doing very well so far, the drug works and keeps his PSA low and stable.
My question here is, is it safe for him to take Cialis? For those that don't know, it's used to treat impotence and BPH. Yes, he wants to have his libido back and the treatment is supposed to last 2 whole months.
His URO and his MO both agree that it won't cause any problems but I'm concerned about the testosterone levels, this med is still supposed to increase it and I'm not sure about how it would react alongside Abiraterone.
Any info regarding taking Cialis and Zytiga together would be greatly appreciated.
Thanks in advance.
