Copegus (ribavirin) is a cornerstone antiviral medication indicated for use in combination with other agents for the treatment of chronic hepatitis C virus (HCV) infection in adults. As a nucleoside analogue, it works by inhibiting viral replication, significantly enhancing the efficacy of concomitant antiviral therapies. This combination approach is critical for achieving undetectable viral load and preventing long-term hepatic complications, including cirrhosis and hepatocellular carcinoma. Proper administration under specialist supervision is essential to maximize therapeutic outcomes and manage potential side effects.
Features
- Contains ribavirin as the active pharmaceutical ingredient
- Available in 200 mg film-coated tablets for precise dosing
- Formulated for oral administration with high bioavailability
- Manufactured under strict pharmaceutical quality standards
- Packaged in blister strips to ensure stability and ease of use
Benefits
- Significantly increases the rate of sustained virologic response (SVR) when combined with peginterferon alfa or direct-acting antivirals
- Reduces viral load to undetectable levels, decreasing liver inflammation and fibrosis progression
- Lowers the risk of HCV transmission by suppressing viral replication
- Helps prevent long-term complications such as liver cirrhosis, decompensation, and hepatocellular carcinoma
- Contributes to improved quality of life and long-term survival in appropriately selected patients
- Supports treatment individualization based on viral genotype and patient-specific factors
Common use
Copegus is used in combination with other antiviral medications, such as peginterferon alfa or modern direct-acting antivirals (DAAs), for the treatment of chronic hepatitis C in adults. It is indicated for patients with compensated liver disease, including cirrhosis, and is tailored according to HCV genotype and treatment history. The combination therapy is designed to achieve sustained virologic response, defined as undetectable HCV RNA 12 or 24 weeks after completing treatment.
Dosage and direction
The dosage of Copegus is weight-based and must be individualized. The typical regimen is 1000 mg per day (for patients weighing <75 kg) or 1200 mg per day (for patients weighing ≥75 kg), administered in two divided doses with food. Dosage adjustments may be required based on renal function, hemoglobin levels, and other patient-specific factors. Treatment duration varies from 24 to 48 weeks depending on HCV genotype, prior treatment response, and presence of cirrhosis. It must always be used in combination with another antiviral agent as prescribed.
Precautions
- Treatment must be supervised by a physician experienced in managing chronic hepatitis C.
- Pregnancy must be excluded before initiation and prevented during treatment and for 6 months afterward due to teratogenic risks.
- Regular monitoring of hematologic parameters (hemoglobin, neutrophils, platelets), renal function, and thyroid function is mandatory.
- Use with caution in patients with cardiac disease, history of depression, or autoimmune disorders.
- Ribavirin may cause hemolytic anemia; dose reduction or discontinuation may be necessary.
Contraindications
- Pregnancy, planned pregnancy, or unwillingness to use effective contraception.
- Severe hepatic impairment or decompensated cirrhosis.
- History of severe pre-existing cardiac disease.
- Hemoglobinopathies (e.g., thalassemia, sickle-cell anemia).
- Hypersensitivity to ribavirin or any component of the formulation.
- Autoimmune hepatitis.
- Use with didanosine (due to risk of fatal lactic acidosis).
Possible side effects
- Hemolytic anemia (common)
- Fatigue, headache, insomnia
- Nausea, anorexia, weight loss
- Pruritus, dry skin, rash
- Depression, irritability, anxiety
- Cough, dyspnea
- Thyroid dysfunction
- Increased uric acid levels
Drug interaction
- Contraindicated with didanosine (increased risk of mitochondrial toxicity).
- May interact with azathioprine, increasing myelosuppression.
- Antacids may reduce absorption; administer with a time gap.
- Use with caution alongside other myelosuppressive agents.
- Potential interaction with nucleoside analogues used in HIV treatment.
Missed dose
If a dose is missed, it should be taken as soon as remembered on the same day. However, if it is nearly time for the next dose, the missed dose should be skipped. Doubling the dose is not recommended. Consistent adherence is critical to treatment success.
Overdose
Ribavirin overdose may exacerbate its known toxicities, particularly hemolytic anemia. There is no specific antidote. Management is supportive and includes monitoring of hematologic parameters and vital signs. Hemodialysis may remove a small fraction of the drug. Medical attention should be sought immediately.
Storage
Store below 30°C (86°F) in a dry place. Keep in the original blister pack to protect from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
“In our clinical experience, Copegus remains a vital component of combination therapy for eligible hepatitis C patients, particularly in resource-limited settings or specific genotype scenarios. Its well-characterized safety profile and efficacy in achieving SVR make it a reliable option when used judiciously.” – Hepatology Specialist
“While newer regimens have expanded options, ribavirin-containing protocols like those with Copegus continue to play a role in difficult-to-treat populations, including those with genotype 3 and cirrhosis.” – Clinical Virologist
