The CDC is offering Doxycycline, also known as Doxypep, as an option to prevent STIs like syphilis, gonorrhea, and chlamydia up to 72 hours after oral, vaginal, or anal sex.

With STI rates on the rise in the U.S., consider adding another tool to your STI prevention kit.

Doxycycline post-exposure prophylaxis, or Doxy-PEP for short, is an antibiotic that the CDC’s draft recommendations(opens in a new tab) are calling for to give to gay, bisexual, and other men who have sex with men, as well as transgender women who have increased chances of getting an STI.

A doctor can prescribe patients with a 200 mg dose of Doxy-PEP(opens in a new tab) no more than 72 hours after oral, vaginal or anal sex. While it’s not FDA-approved yet, you can ask your doctor about doxypep as an option for you.
