Summary
digoxin

Digoxin (Lanoxin) is a medicine that helps your heart pump better. It is used to treat heart failure and control irregular heartbeats.

sofosbuvir/velpatasvir

Vosevi is a drug that combines three medicines into one tablet. It is used to treat hepatitis C in adults who have already tried other treatments.

What It Treats
digoxin

Digoxin is used to treat mild to moderate heart failure in adults. It helps the heart pump more blood with each beat. Digoxin is also used in children with heart failure to help their heart work better. In adults, it can control a fast and irregular heartbeat called atrial fibrillation.

sofosbuvir/velpatasvir

Vosevi treats chronic hepatitis C (HCV) infection in adults. It is for those without cirrhosis or with compensated cirrhosis (Child-Pugh A). You can use it if you have genotype 1, 2, 3, 4, 5, or 6 HCV. You must have already been treated with a hepatitis C medicine containing an NS5A inhibitor, or sofosbuvir without an NS5A inhibitor (for genotypes 1a or 3).

How It Works
digoxin

Digoxin belongs to a class of drugs called cardiac glycosides. It works by making the heart muscle contract more strongly. It also slows down the electrical signals in the heart, which can help control irregular heartbeats.

sofosbuvir/velpatasvir

Vosevi contains sofosbuvir, velpatasvir, and voxilaprevir. Sofosbuvir blocks a protein called NS5B polymerase that the hepatitis C virus needs to multiply. Velpatasvir blocks the NS5A protein, and voxilaprevir blocks the NS3/4A protease protein, both of which the virus also needs.

How to Read This digoxin vs sofosbuvir/velpatasvir Comparison

digoxin is classified in the Cardiac Glycoside drug class, while sofosbuvir/velpatasvir sits within the NS5B/NS5A Inhibitor (HCV) 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, digoxin has 23,407 submissions while sofosbuvir/velpatasvir has 8,251. 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 this combination can cause the level of digoxin in your blood to increase.. 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 digoxin or sofosbuvir/velpatasvir.
