Hi there,
Just had a look at what PREP is..?
What I've seen that "stands out" regarding the drug is the "kidney function" must be normal, should one decicide to take the drug as a prevention.?
Looks like there a fair few health checks, some of which would be covered in your D check up. (Kidney function.)
Other tests would involve regular visits to an STD clinic for evaluation too. (From what I've seen.)
Regarding the "sexual health" side of stuff? I've personally found these clinics & tests more "companionate" than my diabetes team?
(Long story involving a disgruntled/malicious ex with a nasty SOH.)
At the end of the day, the blurb I've seen still recommends traditional "barrier" use during sex In conjunction with the meds. (Condoms.)
Have you asked your GP, regarding PREP?
Hope this helps.
