That's the same concern that was raised with birth control pills back when they first came out, but they've proven to be incredibly effective when measuring actual use (rather than "ideal" use, which is ridiculously inaccurate). Given how many people are already on at least one daily medication, adding another pill is a pretty low barrier. It's much easier to remember to take a pill every morning than it is to remember to (a) stock up on condoms, (b) bring them with you on a date, (c) put one on in the heat of the moment, etc - you get the idea. This isn't just speculation; it's supported by the clinical trials and post-clinical data as well, which is why PrEP is not only approved by the FDA, but actively recommended by the WHO and other organizations.
