Side-by-side comparison of ledipasvir/sofosbuvir and warfarin. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
minor Known Drug Interaction
Frequent monitoring of relevant laboratory parameters (e.g., International Normalized Ratio [INR] in patients taking warfarin, blood glucose levels in diabetic patients) or drug concentrations of concomitant medications such as cytochrome P450 substrates with a narrow therapeutic index (e.g., certain immunosuppressants) is recommended to ensure safe and effective use.
Harvoni
Coumadin, Jantoven
Harvoni is a medicine that contains ledipasvir and sofosbuvir. It is used to treat chronic hepatitis C virus (HCV) infection in adults and children 3 years and older.
Warfarin is a medicine that helps prevent blood clots. It is used to treat and prevent dangerous clots from forming in your body.
Harvoni treats chronic Hepatitis C virus (HCV) genotypes 1, 4, 5, or 6. It can be used if you don't have cirrhosis or if you have compensated cirrhosis. If you have genotype 1 with decompensated cirrhosis or are a liver transplant recipient with genotype 1 or 4, you will take Harvoni with another medicine called ribavirin.
Warfarin is used to prevent and treat blood clots in your veins and lungs. It can also prevent clots if you have atrial fibrillation (irregular heartbeat) or a replacement heart valve. After a heart attack, it can lower the risk of death, another heart attack, or a stroke.
Harvoni contains two medicines that stop the hepatitis C virus from multiplying in your body. Ledipasvir blocks a protein called NS5A. Sofosbuvir blocks another protein called NS5B.
Warfarin works by blocking your body's use of vitamin K. Vitamin K is needed to make blood clotting factors. By blocking vitamin K, warfarin makes your blood less likely to clot.

Harvoni can cause Hepatitis B to become active again if you have had it in the past. This can cause serious liver problems, including liver failure and death. Your doctor will test you for Hepatitis B before you start Harvoni and monitor you during and after treatment.
Warfarin can cause major or fatal bleeding. You must have your blood tested regularly (INR) while taking warfarin. Many things, like other medicines and diet changes, can affect your INR. Tell your doctor about any bleeding and follow their instructions to prevent bleeding.
If you are pregnant or plan to become pregnant, talk to your doctor before taking Harvoni. If Harvoni is taken with ribavirin, it is unsafe during pregnancy. Talk to your doctor if you are breastfeeding or plan to breastfeed.
Warfarin can harm your unborn baby, especially during the first three months of pregnancy. Do not take warfarin if you are pregnant, unless you have a mechanical heart valve and your doctor says the benefits outweigh the risks. Talk to your doctor if you are breastfeeding, and watch your baby for bruising or bleeding.
How to Read This ledipasvir/sofosbuvir vs warfarin Comparison
ledipasvir/sofosbuvir is classified in the NS5A/NS5B Inhibitor (HCV) drug class, while warfarin sits within the Vitamin K Antagonist (Anticoagulant) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, ledipasvir/sofosbuvir has 10,872 submissions while warfarin has 37,036. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to taking these drugs together can change how your blood thins, which affects your lab test results.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for ledipasvir/sofosbuvir or warfarin.
