Summary
Nirmatrelvir is used to treat COVID-19, which is a viral infection caused by the coronavirus. It helps reduce the severity of symptoms and the risk of hospitalization when taken early in the infection.
Nirmatrelvir works by inhibiting a viral enzyme called protease, which is essential for the virus to multiply. By blocking this enzyme, it helps reduce the virus's ability to spread in your body.
The usual dose for adults is 300 mg taken twice daily. It is taken orally, which means by mouth, with or without food. Always follow your doctor's instructions for the best results.
Common side effects include mild stomach upset, which refers to discomfort in the stomach, and nausea, which is a feeling of wanting to vomit. These effects are usually not severe.
