Summary
Emtricitabine is used to treat HIV infection, which is a virus that attacks the immune system. It helps lower the amount of virus in the body, improving immune function and reducing the risk of developing AIDS, which is a severe stage of HIV infection.
Emtricitabine works by inhibiting the reverse transcriptase enzyme, which is essential for the HIV virus to replicate. By blocking this enzyme, it reduces the amount of virus in the body, allowing the immune system to function better and manage HIV infection.
The usual dose of Emtricitabine for adults is 200 mg once daily. It is taken orally, which means by mouth, with or without food. The tablet should be swallowed whole, not crushed or chewed. Always follow your doctor's specific dosing instructions.
Common side effects of Emtricitabine include headache, diarrhea, and nausea, which is a feeling of sickness with an inclination to vomit. These effects vary from person to person and are usually mild. If you notice new or worsening symptoms, contact your doctor.
Emtricitabine can cause lactic acidosis, which is a buildup of lactic acid in the blood, and severe liver problems. It is not recommended for people with severe kidney problems. Always consult your doctor about any concerns or conditions that might affect your use of Emtricitabine.
