ADULTS: PO Patients £ 75 kg: two 200 mg capsules in the morning and three 200 mg capsules in the evening. Patients > 75 kg: three 200 mg capsules in the morning and evening. In patients whose hemoglobin levels fall < 10 g/dL, reduce the ribavirin dose to 600 mg/day (one 200 mg capsule in the morning and two 200 mg capsules in the evening). Permanently discontinue ribavirin in patients whose hemoglobin levels fall < 8.5 g/dL. In patients with a history of stable cardiovascular disease, a permanent dose reduction of ribavirin to 600 mg/day is required if the hemoglobin decreased by ³ 2 g/dL during any 4-wk treatment period. Permanently discontinue ribavirin therapy in patients with cardiac history if the hemoglobin remains < 12 g/dL after 4 wk on a reduced ribavirin dose.

Contraindication ::

 Assessment/Interventions

• Obtain patient history, including drug history and any known allergies.
• Obtain baseline reticulocyte count and monitor daily.
• Monitor I&O.
• Obtain baseline vital signs and monitor at regular intervals during administration.
• Assess respiratory status prior to starting drug and monitor closely during treatment.
• If respiratory status deteriorates rapidly, discontinue treatment and notify health care provider.
• Obtain baseline digoxin levels on patients who are concomitantly receiving digoxin and monitor for digoxin toxicity.
• Assess skin prior to starting drug and observe for changes.
