Feature ImageOpen Door offers comprehensive primary HIV care. Additional services include pre-exposure prophylaxis (PrEP), post-exposure prophylaxis (PEP), and hepatitis C treatment.

PrEP may be suitable if you are HIV-negative, but your lifestyle puts you at risk of contracting the virus. It involves taking daily medication as a preventive measure. According to the CDC, research has shown that taking PrEP daily reduces the risk of getting HIV from sex by about 99%. Daily PrEP also reduces HIV risk among people who inject drugs by at least 74%.

PEP is an emergency treatment that you can start within 72 hours of a potential HIV exposure to protect yourself from becoming infected.

Hepatitis C treatment is included within our HIV Services because many people who are at risk of getting HIV are also at risk of getting hepatitis C. The CDC reports that roughly 25% of people with HIV in the United States have hepatitis C as well.
