CDC Recommends An Antibiotic To Prevent Sexually Transmitted Infections!

The fight against the spread of sexually transmitted infections (STIs) has taken a clever turn. The Centers for Disease Control and Prevention (CDC) has now issued draft recommendations highlighting the potential use of an antibiotic regimen. It is none other than Doxy-PEP, in STI prevention. Let’s delve into the details.

The Rise of Doxy-PEP

Doxy-PEP involves taking the antibiotic doxycycline after a potential exposure to an STI. It does not suggest waiting until a disease displays and gets diagnosed. Dr. Jonathan Mermin, head of the CDC’s National Center for HIV, Viral Hepatitis, STD, and TB Prevention, showed his hope in an interview with CBS News.

It’s going to take game-changing innovations for us to turn the STI epidemic around. And Doxy-PEP is the first major new prevention intervention we have for STIs in decades,” says Dr. Jonathan Mermin.

Who is it For?

The CDC currently targets its recommendation at specific high-risk groups. These groups include gay and bisexual men, other men who have sex with men, and transgender women. The antibiotic is recommended especially to the ones who have been diagnosed with bacterial STIs like gonorrhea, chlamydia, or syphilis in the past year.

If the draft is accepted, the recommended dose would be to take a 200 mg dose of doxycycline. It should be taken within 72 hours after unprotected oral, vaginal, or anal intercourse.

This approach can raise questions regarding its use to the broader population. However, the CDC does see potential in the Doxy-PEP approach. It still needs more data to confidently expand its recommendation to other groups.

Is This a New Strategy?

Interestingly, the CDC isn’t the trailblazer in recommending Doxy-PEP. Health departments in states like California, Michigan, and New Mexico have already set guidelines in place, recognizing its benefits.

David Harvey, executive director of the National Coalition of STD Directors, has called the proposal. He stated that there isn’t a significant amount of funding for STI care, prevention, and research. Therefore, this development is profound for the field.

Efficacy and Benefits

Clinical trials offer a promising outlook for Doxy-PEP. Research suggests that individuals who stick to the Doxy-PEP regimen contract STIs like gonorrhea, chlamydia, and syphilis way less often than those who don’t. The treatment is especially effective in STIs like chlamydia and syphilis. It slashes the risk by almost 80%, and it curbs the danger of gonorrhea by about 50%.

Concerns and Monitoring

As with any medical intervention, there are concerns. there is a worry surrounding the widespread use of antibiotics, including doxycycline. This is a potential development of antibiotic resistance. Resistance happens when bacteria grow to protect themselves from the drugs meant to kill them. It makes treatments less effective over time. This concern isn’t new, and the CDC is fully aware. They are poised to closely monitor any emerging resistance and adjust guidelines as necessary.

“There are important questions that remain regarding potential risks,” says Dr. Mermin addressing the concerns.

As a part of the given guidelines, the CDC is emphasizing the need for steady monitoring and evaluation of Doxy-PEP’s implementation over time.


The CDC’s move is indeed significant. There are a few concerns. However, the potential benefits of Doxy-PEP in stopping the spread of STIs cannot be understated. The ongoing public feedback period, which will last until Nov. 16, will certainly provide a wide perspective on the matter.

In the fight against STIs, every weapon in the arsenal counts. As the science continues to evolve, innovations like Doxy-PEP could prove invaluable in curbing the spread and offering protection to those most at risk. We’ll be keeping a close eye on further developments and what they mean for STI prevention strategies in the future.
