Over the past year, there has been a lot of discussion about including Ribavirin with Direct Acting Antivirals (DAAs) in the treatment of Hepatitis C. In this article, I will show that there is no value at all in combining Ribavirin with DAAs in the treatment of Hepatitis C. Indeed, the research suggests that adding Ribavirin actually reduces the Hepatitis C cure rates in many situations.
Because adding Ribavirin definitely improved the effectiveness of Interferon based treatment of Hepatitis C there has been the idea that adding Ribavirin to Sofosbuvir based treatments such as Epclusa or Sofosbuvir + Daclatasvir would be a good idea. This despite the fact that Ribavirin is a highly toxic drug with many, many potentially dangerous side effects. After several years of monitoring the treatment of Hepatitis C patients being treated with the combination of DAAs the evidence is in that adding Ribavirin to modern Hep C treatment has no value in almost every situation. The graph below is from an article published in the Journal of Hepatology in January 2019 called: Real-world effectiveness of daclatasvir plus sofosbuvir and Velpatasvir/Sofosbuvir in hepatitis C genotype 2 and 3. This study was of over 5,000 patients being treated by the USA Department of Veterans Affairs and shows that adding Ribavirin actually reduces cure rates in patients with G2 and G3.
There have been numerous studies that show that adding Ribavirin to Sofosbuvir based Hepatitis C treatment can reduce the cure rates.
The study by Sulkoski et al. also shows a five percent reduction in cure rates for people who added Ribavirin to their Hepatitis C treatment with Sofosbuvir + Daclatasvir.
|Sulkowski et al.(AI444040)7||DCV+SOF for 12 weeks vs. DCV+SOF+RBV for 12 weeks||100% vs. 95%|
|DCV+SOF for 24 weeks vs. DCV+SOF+RBV for 24 weeks||100% vs. 95%|
Below is a long, long list of the side effects of Ribavirin and the damage it can do.
The toxicity of Ribavirin is not debated. Everyone agrees that Ribavirin is a very toxic chemical. However, the argument has always been that the risk of damage from Ribavirin’s toxicity is offset by the fact of its antiviral qualities.
This argument cannot be used in the case of Hepatitis C treatment because there is no benefit in adding Ribavirin to Sofosbuvir based Hepatitis C treatment. Indeed there is a distinct disincentive to adding Ribavirin to Hep C treatment because adding Ribavirin reduces cures rates!
So why would anyone consume a toxic drug that reduces their chance of a cure? Why would any doctor prescribe a toxic drug that reduces cure rates?
Hell… I don’t know the answer; maybe it’s just plain ignorance? Maybe it’s a disinformation campaign by the manufacturers of Ribavirin?
I don’t know why… it seems crazy to me and it is the reason I am taking the time to write this post, so people know the truth about Ribavirin.
It is important that a male taking Ribavirin should not cause pregnancy during the use of Ribavirin. It is also important that a female should not fall pregnant during the time she is using Ribavirin. There is a risk that Ribavirin will cause genetic defects and pregnancy should not be considered until at least 6 months after the end of treatment with Ribavirin.
A negative pregnancy test is needed in women who are of childbearing age before starting treatment with Ribavirin. Two forms of birth control must be used together during treatment and for 6 months after treatment ends. You will need to have pregnancy tests done regularly to make sure you are not pregnant while being treated with this medicine and for at least 6 months after your treatment ends
Do not use Copegus® in combination with didanosine (Videx®, Videx® EC). Using these medicines together may cause serious medical problems.
Ribavirin may cause some people to be agitated, irritable, or display other abnormal behaviours. In Hep C circles we call this “Riba Rage”.
It may also cause some people to have suicidal thoughts and tendencies or to become more depressed.
Check with your doctor right away if you have back, leg, or stomach pains; bleeding gums; chills; dark urine; difficulty breathing; fever; general body swelling; headache; loss of appetite; nausea or vomiting; nosebleeds; pale skin; sore throat; unusual tiredness or weakness; or yellowing of the eyes or skin. These could be symptoms of a blood disorder called anaemia, which is caused by Ribavirin.
This medicine may cause serious types of allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention.
