I read I'm forbidden to use other languages than English on this website, so I can't give you the text but in my country both uses of PrEP are part of the guide-lines our general practitioners use. The local health counsels who offer sexual health clinic also use these.
Wikipedia too says 2-1-1 is off-label, but in Europe there are two ways to take this medication and it's up to the doctor.
Mine told me she hadn't heard of it before when I asked for it. So she did her research first, and she told me initially she wasn't keen on proscribing it because it seemed illogical to give medication to someone who isn't ill.
But anyway, in my case she was still a bit worried about my kidney-function as I'm also taking other medication and we had a very open talk about dating.
She made me promise to really stick to the event-schedule which starts with waiting 2 hours between taking PrEP and having sex.
That's not a problem because having a shower, cleaning out, brushing my teeth and getting dressed usually takes me about an hour to an hour-and-half already. So if my date comes to my house I jus have him come half an hour after that and if I go to my date it's almost always two hours later.
Last time I dated I used the alarm-clock on my smart-phone which was really funny when it went off when I was at this guys house. LOL
Oh and my doctor told me that if I did make a mistake by missing a dose or take it to late or don't wait long enough to get in touch immediately if I had sex without a condom, and ask for PEP.
So I do not think you are right and I trust my own doctor more than I trust you.
You are not very clear what your are saying.
What do you mean when saying half way through you are not suggesting one way to use PrEP or the other, but after that you list only reasons do use it daily.
I don't mean to insult you, but there are people online saying stupid things about Covid-19 not being real and that vaccinations don't work or are a conspiracy who tell me to read for myself, examine the data for myself, bla bla bla.
I'm not doing that, I had my two slabs and no problem.
So I hope you don't mind I don't listen to you now. Yo
