Copegus, a cornerstone in antiviral therapy, combines with peginterferon alfa to form a potent treatment regimen for chronic hepatitis C virus (HCV) infection. As a nucleoside analogue, it inhibits viral replication, significantly improving sustained virological response rates. This medication is tailored for adult patients, with dosing meticulously adjusted based on viral genotype and patient weight to optimize efficacy while managing potential side effects. Trusted by hepatologists globally, Copegus represents a critical component in the journey toward viral eradication.
Features

Common use
Copegus is indicated for the treatment of chronic hepatitis C in combination with peginterferon alfa in adults. It is prescribed for patients with compensated liver disease who have not been previously treated with interferon alpha, as well as for patients who have relapsed after previous interferon therapy. The medication is particularly effective against HCV genotypes 1, 2, and 3, with treatment duration varying from 24 to 48 weeks based on viral genotype and treatment response.
Dosage and direction
The recommended dosage of Copegus depends on patient body weight and HCV genotype. For genotype 1 or 4: patients weighing <75 kg should take 1000 mg daily (400 mg in the morning and 600 mg in the evening), while those weighing ≥75 kg should take 1200 mg daily (600 mg twice daily). For genotype 2 or 3: the recommended dose is 800 mg daily (400 mg twice daily). Tablets should be taken with food to enhance absorption. Treatment duration is typically 48 weeks for genotype 1 or 4, and 24 weeks for genotype 2 or 3. Regular monitoring of virological response is essential, and treatment should be discontinued if HCV RNA remains detectable at week 24.
Precautions
Copegus may cause hemolytic anemia, which can be severe. Hemoglobin levels should be monitored before therapy and at weeks 2 and 4 of therapy, or more frequently if clinically indicated. The medication is contraindicated in pregnancy due to significant teratogenic effects; effective contraception must be used by both female patients and female partners of male patients during treatment and for 6 months after discontinuation. Psychiatric symptoms, including depression, suicidal ideation, and aggressive behavior, may occur and require close monitoring. Patients with pre-existing cardiac disease should be monitored for worsening cardiac function. Ophthalmological disorders have been reported with ribavirin therapy.
Contraindications
Copegus is contraindicated in patients with known hypersensitivity to ribavirin or any component of the formulation. It must not be used in pregnant women or men whose female partners are pregnant. The combination therapy with peginterferon alfa is contraindicated in patients with autoimmune hepatitis, decompensated liver disease, or severe pre-existing cardiac disease. Patients with hemoglobinopathies (e.g., thalassemia major, sickle-cell anemia) should not receive Copegus. Concomitant administration with didanosine is contraindicated due to risk of fatal hepatic failure and peripheral neuropathy.
Possible side effects
The most common serious adverse reaction is hemolytic anemia, which may require dose reduction or discontinuation. Other frequently reported side effects include fatigue, headache, nausea, insomnia, depression, irritability, rash, pruritus, neutropenia, and thrombocytopenia. Less common but serious adverse effects may include pancreatitis, pulmonary dysfunction, severe ophthalmological disorders, and hearing impairment. Thyroid dysfunction and hyperuricemia have been observed. Patients may experience flu-like symptoms, including fever, rigors, and myalgia, particularly at the beginning of therapy.
Drug interaction
Copegus may interact with nucleoside analogues, particularly increasing the risk of mitochondrial toxicity when combined with didanosine or stavudine. Azathioprine metabolism may be inhibited, increasing the risk of pancytopenia. Concomitant use with other myelosuppressive agents may enhance bone marrow suppression. Ribavirin may reduce the activation of clopidogrel to its active metabolite, potentially diminishing its antiplatelet effect. Antacids containing aluminum and magnesium may decrease ribavirin absorption if taken simultaneously.
Missed dose
If a dose of Copegus is missed, patients should take it as soon as possible on the same day. However, if the missed dose is not remembered until the next day, the patient should skip the missed dose and resume the regular dosing schedule. Patients should never take a double dose to make up for a missed dose. Consistent adherence to the prescribed dosing regimen is crucial for treatment success, and any pattern of missed doses should be discussed with the healthcare provider.
Overdose
There is no specific antidote for Copegus overdose. The maximum tolerated dose of ribavirin has not been established, but single doses of up to 2000 mg have been administered without reported serious adverse effects. However, acute overdose would be expected to produce exaggerated pharmacological effects, particularly hemolytic anemia. Management should include general supportive measures, with close monitoring of hematological parameters. Hemodialysis removes approximately 50% of ribavirin, but its effectiveness in overdose management has not been established.
Storage
Store Copegus tablets at room temperature (15-30°C or 59-86°F) in the original container with the desiccant provided. Keep the container tightly closed and protect from moisture. Do not remove the desiccant from the container. Keep out of reach of children and pets. Do not use tablets that are discolored or show signs of deterioration. Properly dispose of any unused medication after the expiration date or upon completion of therapy.

Reviews
Clinical studies demonstrate that Copegus in combination with peginterferon alfa achieves sustained virological response rates of 41-52% in genotype 1 patients and 76-82% in genotype 2/3 patients. Hepatologists report satisfactory efficacy with manageable side effects when patients are appropriately selected and monitored. Patients note the importance of adherence despite side effects, with many achieving viral clearance after completing the full course of therapy. Regular monitoring and supportive care are consistently emphasized as crucial for treatment success.
