- Dosing Adjustments: Adjustments may be necessary based on individual tolerance and the presence of side effects. Regular monitoring is essential.
- Duration of Treatment: Ribavirin is often used in combination with other antiviral medications. The duration of the treatment regimen typically lasts from 24 to 48 weeks, depending on the specific viral strain and liver function.
