According to the CDC guidelines, oral PrEP for coitally timed use is not recommended. On-demand PrEP, defined as taking two tablets of TDF/FTC 2-24 hours before sexual activity, followed by one tablet the day after and one tablet the day after that (total of four tablets in a 72-hour period), is endorsed by the International Antiviral Society-USA and the WHO as potential dosing options for MSM with infrequent sexual exposures.

PrEP should be considered for MSM who continue to engage in other high-risk behaviors. Guidelines also suggest that PrEP be considered for individuals who inject drugs, as well as for heterosexually active serodiscordant women and men.

For additional information, refer to the CDC guidelines.
