Pre exposure prophylaxis as a preventative measure for HIV

Pre-exposure prophylaxis (PrEP) is a HIV medication that when used consistently, reduces the risk of HIV infection during sex by over 90%. WHO PrEP guidelines currently recommends the use of PrEP taken daily for both men and women who are at substantial risk of acquiring HIV. Daily PrEP use provides the highest amount of medication in the blood and body tissues and, thus, the highest level of protection. If you take PrEP daily, you may still be protected, even if you miss a dose occasionally.
