Introduction

Emtricitabine is used in combination with other medications for HIV post-exposure prophylaxis. The decision to start post-exposure prophylaxis after a possible exposure to HIV is complex, and the standard of care is to initiate post-exposure prophylaxis medication only after laboratory testing. Seeking immediate medical attention is the best option. However, in an emergency or disaster situation in which medical care is unavailable, take this medication, along with tenofovir and raltegravir, as soon as possible (and within 72 hours) to prevent infection if you believe you have suffered a major exposure to HIV. Immediately seek qualified medical care.

When to avoid

Do not take if you have hepatitis B. Do not take to prevent infections other than HIV. Do not take as pre-exposure prophylaxis. Do not take if HIV status is unknown or positive. This medication must only be used by individuals confirmed to be HIV-negative immediately prior to starting treatment. Do not take if signs or symptoms of HIV infection are present.

When is it dangerous

Emtricitabine and tenofovir can cause mental health side effects including depression and suicidality. Do not stop taking this medication once you start without consulting a medical provider. This medication can cause severe worsening of hepatitis B. This medication can cause kidney problems (renal failure), immune system problems (immune reconstitution syndrome), bone loss, and liver failure.

When is it used

HIV post-exposure prophylaxis emtricitabine 200 mg by mouth once a day PLUS tenofovir 300 mg by mouth once a day PLUS raltegravir 400 mg by mouth twice a day
