Copegus (Ribavirin) Buyer and Patient Handbook in Singapore
Copegus (Ribavirin) is an antiviral medication indicated for the treatment of chronic Hepatitis C infection, typically used in combination with other agents. It belongs to the ribavirin class of nucleoside analogues, is approved by the Health Sciences Authority (HSA) of Singapore, and is supplied as oral tablets.
What is Copegus?
Copegus is a brand-name pill that contains the active ingredient ribavirin, a synthetic nucleoside analogue that interferes with viral RNA synthesis. It is prescribed as part of combination therapy for hepatitis C genotypes 1, 2, 3, 4, 5, and 6. The medication is available in 100 mg tablets and is regulated under Singapore’s HSA-approved drug list.
Who Should Use Copegus?
- Adults (≥ 18 years) diagnosed with chronic hepatitis C who are receiving a physician-approved combination regimen.
- Patients whose viral genotype matches the therapeutic protocol for ribavirin-containing regimens.
- Individuals with adequate renal function (creatinine clearance ≥ 50 mL/min).
How Does It Work?
Ribavirin mimics the natural nucleoside guanosine, becoming phosphorylated inside cells. The phosphorylated forms inhibit viral RNA-dependent RNA polymerase, disrupt viral mRNA capping, and increase mutation rates in the viral genome-ultimately leading to non-viable viral particles.
Impact: Think of the virus as a car; ribavirin removes key components from the engine, preventing the vehicle from running smoothly.
Safety: Ribavirin has a known risk of hemolytic anemia and teratogenicity; therefore, it must be used under strict medical supervision and with appropriate monitoring.
Why Choose Copegus?
- Brand reliability: Copegus is manufactured by a globally recognized pharmaceutical company, ensuring consistent bioavailability and quality control.
- Convenient dosage: Fixed-dose 100 mg tablets simplify titration and adherence.
- Generic alternatives: Ribavirin is available as generic tablets with comparable bioequivalence, offering a lower-cost option for patients who qualify.
Off-label use is not advised without specialist consultation.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- Standard adult regimen: 100 mg taken twice daily (total 200 mg per day).
- Weight-based adjustment: For patients > 75 kg, the total daily dose may be increased to 120 mg (i.e., 600 mg twice daily) as directed by the treating clinician.
How to Take
- Swallow tablets whole with a full glass of water.
- Can be taken with or without food; consistency each day reduces gastrointestinal upset.
Missed Dose
- If you remember the missed dose within 12 hours, take it immediately.
- If more than 12 hours have passed, skip the missed dose and resume the regular schedule. Do not double-dose.
Overdose
- Symptoms may include severe Nausea, Vomiting, and rapid breathing.
- Seek emergency medical care promptly; inform the team that ribavirin was taken in excess.
Special Populations
| Population | Recommendation |
|---|---|
| Renal impairment (CrCl < 50 mL/min) | Dose reduction required; consult a specialist. |
| Elderly (≥ 65 years) | Start at the lower end of the dosing range; monitor hemoglobin. |
| Pregnancy & breastfeeding | Contraindicated - ribavirin is teratogenic. Use effective contraception. |
| Pediatric | Not approved for use in children under 18 years. |
Lifestyle & Diet
- Avoid grapefruit juice as it may increase plasma concentrations.
- Limit alcohol to reduce hepatic stress; discuss safe limits with your clinician.
- Stay hydrated to support renal clearance and lessen hemolysis risk.
Precautions and Warnings
- Hemolytic anemia: Monitor complete blood count (CBC) at baseline, weekly for the first month, then monthly.
- Teratogenicity: Pregnancy must be excluded before starting therapy and maintained throughout treatment + 6 months after discontinuation. Effective contraception includes combined hormonal methods or an intrauterine device.
- Renal function: Dose adjustments are mandatory for moderate to severe renal impairment.
- Psychiatric effects: Rare cases of Depression and suicidal ideation reported; seek help if mood changes occur.

Frequently Asked Questions
How long does a typical Copegus-containing hepatitis C treatment last?
A standard course lasts 24 weeks when combined with peginterferon, though newer regimens may shorten therapy to 12 weeks without ribavirin.
Can I take Copegus with coffee or tea?
Yes, moderate caffeine intake does not affect ribavirin levels. Excessive caffeine may increase Anxiety, so monitor your tolerance.
Is alcohol completely prohibited while on Copegus?
Alcohol is not strictly prohibited but should be limited. Heavy drinking can worsen liver injury and reduce treatment efficacy.
What should I do if I develop a rash?
Stop the medication and contact a healthcare professional immediately. A rash could signal an allergic reaction.
Does Copegus interact with over-the-counter vitamins?
Most vitamins are safe, but high-dose vitamin C may increase urinary excretion of ribavirin, potentially lowering effectiveness. Discuss supplement use with your clinician.
Can I become pregnant while taking Copegus?
No. Ribavirin is teratogenic; you must use reliable contraception throughout treatment and for 6 months after the last dose.
How often will my blood be monitored?
Typically, CBC and renal function are checked weekly for the first month, then monthly for the remainder of therapy.
Will I need a special diet while on Copegus?
No specific diet is required, but avoid grapefruit juice and maintain adequate hydration.
What happens if I miss several doses in a row?
Contact your healthcare provider promptly. They may advise a temporary pause or dose adjustment based on your viral load and blood counts.
Is Copegus covered by Singapore’s Medisave or private insurance?
Coverage varies by plan. Check with your insurer or the hospital’s finance department for details on reimbursement.

Reviews
Just started week 3. It's brutal, honestly. The fatigue hit me like a truck by day 5. I'm sleeping 10 hours and still feel drained. Plus, this constant metallic taste in my mouth makes everything taste like I'm chewing on old coins. My doc said it's normal, but wow. Trying to push through, hoping it gets better.
One month in. The fatigue is real, but the worst part is the dry, itchy skin. My arms look like a lizard's. A nurse told me to slather on thick moisturizer right after my shower while my skin is still damp. It helps a bit. Also, drinking water constantly is non-negotiable. Dehydration headaches are another level of awful.
Been on this for 6 months now. You learn tricks. The metallic taste? Sugar-free hard candies are a lifesaver. I keep a jar on my desk. The fatigue never fully goes away, but I've found if I take my main dose right after dinner, I can sleep through the worst of it. Blood counts are stable, so it's a trade-off I'm willing to make for now.
Almost a year on Copegus. The key is routine. I take it with a full meal, never on an empty stomach, or the nausea is instant. I also split my big evening dose into two smaller ones, 30 mins apart, as my doctor suggested. Makes a huge difference with the sleepiness. Lab results are great, but it's a marathon, not a sprint.
Two years down. It controls the virus, but the side effects are cumulative for me. The anemia got pretty bad around the 18-month mark. I need occasional shots to boost my red blood cells. Also, my hair thinned out a lot. On the plus side, I've learned to manage the fatigue with short naps. It's a part of my life now.
My hack: ginger tea for the nausea. Seriously, better than the anti-nausea pills they gave me. I brew a strong cup and sip it slowly after taking the pill. The fatigue is still there, but being strict about a bedtime has helped. Social life has taken a hit, but my viral load is undetectable, so it's worth it.
It's weird. My liver numbers are fantastic now, better than they've been in years. But the mental fog is something else. I forget words mid-sentence. And the irritability? I snap at my family over nothing. It's like it fixed my body but messed with my head. We're adjusting the dose slightly to see if that helps.
Stopped the treatment after 8 months. It was working virologically, but the side effects became too much. The shortness of breath and crushing depression were deal-breakers for me. It's a powerful drug, and it doesn't agree with everyone. I don't regret trying, but I'm exploring other options now.
