What is the oral dose and frequency of sofosbuvir for a patient?

The appropriate oral dose of sofosbuvir for treating chronic hepatitis C infection in adults is 400 mg taken once daily. This dosage is supported by clinical guidelines and research indicating that this specific dose maximizes efficacy while minimizing potential side effects. Sofosbuvir is a direct-acting antiviral agent that targets the hepatitis C virus, and the once-daily administration helps with adherence to the treatment regimen, making it easier for patients to follow through with their therapy.

The other options reflect incorrect dosing regimens. Dosing that is too low, such as 200 mg once daily or schedules that are not consistent with clinical recommendations, like taking it every other day or in divided doses, might not provide adequate viral suppression and could lead to treatment failure. Therefore, the 400 mg once daily regimen is both effective and convenient, playing a crucial role in managing hepatitis C effectively.
