Medication Overview
Emtricitabine is an antiviral medication used to treat HIV-1 infection. It belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs), which work by blocking the action of reverse transcriptase, an enzyme crucial for the replication of the HIV virus. Emtricitabine is often used in combination with other antiretroviral medications to help reduce the amount of HIV in the blood, improve immune system function, and decrease the risk of developing complications related to HIV.
Who Should Consider Emtricitabine?
Emtricitabine is appropriate for adults and children who:
- Have HIV-1 infection and require combination therapy to manage the virus.
- Are receiving pre-exposure prophylaxis (PrEP), when combined with other antiretroviral drugs, to reduce the risk of contracting HIV.
- Need post-exposure prophylaxis (PEP) in the case of potential HIV exposure, in combination with other antiretrovirals.
How is Emtricitabine Administered?
Emtricitabine is available in tablet or liquid form, and is usually taken once daily, with or without food. It is commonly included in combination therapies, such as Truvada or Descovy, which pair Emtricitabine with other antiretroviral medications like tenofovir.
Important Information for Emtricitabine Users
- How to Use: Take Emtricitabine exactly as prescribed by your healthcare provider. Adhere to the dosing schedule to ensure the medication is effective.

- Side Effects: Common side effects include headache, diarrhea, nausea, and skin discoloration on the palms or soles of the feet. Contact your healthcare provider if you experience severe or unusual side effects.
- Monitoring: Regular blood tests may be required to monitor liver and kidney function, and to ensure that the medication is effectively controlling the HIV virus.
Medication Warnings
- Hepatitis B Reactivation: If you have both HIV and hepatitis B, stopping Emtricitabine may cause severe worsening of hepatitis B. Your healthcare provider will monitor liver function and adjust treatment as needed.
- Lactic Acidosis: In rare cases, Emtricitabine can cause lactic acidosis (buildup of lactic acid in the blood), a potentially fatal condition. Symptoms include muscle pain, trouble breathing, and abdominal pain.
- Liver Problems: Emtricitabine may cause liver issues, including enlarged liver or fatty liver disease. Seek medical attention if you notice symptoms such as jaundice, dark urine, or severe abdominal pain.
