Hi. Iam on PrEP on-demand. i took 2 doses at 8pm, 1 dose after 8pm the next day, and the last dose i took at 9:30pm the next day. As I told you, I took the last dose 1 hour 30 minutes late. Does it affect backup results?
Call the manufacturer if you can't find the answer on the site of the medication. Every med has it's own site. Or talk to the pharmacist.
I hope this topic wasn't on one of your deleted threads.
