Harlem United has decades of experience providing life-saving services aimed at reducing infectious disease transmission and overdose in high-risk communities. In 2004, we became one of the first organizations to offer rapid HIV testing, and in 2007 we began offering syringe exchange. Through robust, peer-supported community outreach, we provide testing services and substance use services to priority populations including people who use drugs, youth, people experiencing homelessness, and people with multiple chronic conditions.

Our Prevention programs offer HIV, Hepatitis C, and other STI testing; patient navigation; syringe exchange; overdose prevention training and Naloxone dispensing; Medicated Assisted Treatment (MAT) navigation; risk reduction and substance use counseling; recovery readiness services; relapse prevention; and more.

Integrated Harm Reduction Program

Harm Reduction programs include drug counseling, mental health counseling, syringe exchange, overdose prevention training, and Buprenorphine navigation.

Testing Services

Testing Services provides free and confidential testing for HIV, Hepatitis C, and Sexually Transmitted Infections. All eligible clients receive patient navigation services which include education about and access to PrEP and PEP.

What is Harm Reduction

Harm Reduction is an approach to care which encourages any positive change in our clients’ choices, with a special focus to decisions that lead to better health and wellbeing. These could be as simple as someone living with diabetes choosing more balanced meal options, or someone engaging in drug use choosing to use clean syringes.
