Sofosbuvir is approved for the treatment of chronic hepatitis C in adults and pediatric patients weighing at least 17 kg (typically ?3 years old). It is effective against various genotypes of the virus, making it a versatile option for patients. The medication is typically used in combination with other drugs, such as:

By blocking this enzyme, Sofosbuvir prevents the virus from multiplying and spreading within the body. In simpler terms, it stops the virus from making copies of itself, allowing the immune system to fight off the infection more effectively.

Sofosbuvir is available in tablet form and is typically taken once daily, with or without food. The standard adult dosage is 400 mg per day. For pediatric patients aged 12 years and older, the dosage may vary based on body weight and the specific treatment regimen. It is essential to follow the healthcare provider's instructions regarding dosage and duration of treatment to ensure the best possible outcome.
