HIV/STI Prevention Program

At Harris County Public Health, we are dedicated to promoting health and wellness through our HIV/STI Prevention Program. Our aim is to prevent HIV infection, STI transmission, and reduce HIV-related illness through a comprehensive and inclusive approach that serves all members of our community, including the LGBTQ+ population.

Our program offers a range of services, including free HIV/STI testing, counseling, education, outreach, and we work in close collaboration with community partners and healthcare providers to provide access to the highest quality resources and support.

Our goal is to promote a healthy quality of life and reduce the spread of HIV. We take pride in our work, and we are committed to serving our community with compassion, dignity, and quality service.

Clinic Services

The Antoine Clinic, located at 5815 Antoine Drive, in Northwest Houston, offers comprehensive sexual health services. We provide STI testing for HIV, Syphilis, Gonorrhea, and Chlamydia with results available in approximately one week.

We also offer PrEP prescriptions for those at risk of contracting HIV. PrEP is a pill taken once a day to prevent HIV.
Lack of insurance should not be a determining factor in accessing this preventative medication. We also offer free resources such as condoms, dental dams, and lubrication are available at no cost. In addition to STI testing and treatment, we also provide vaccinations such as Flu and MPox.

Our team provides linkage to care services to ensure that newly diagnosed patients with HIV can establish appropriate care and treatment. Our services are free of cost to you, and we welcome uninsured patients. We have bilingual staff (Spanish) if needed. We offer gender-affirming care. Contact us today to schedule an appointment.
