moderate Known Drug Interaction
John's wort, carbamazepine): May decrease concentrations of sofosbuvir, velpatasvir, and/or voxilaprevir. John's wort, carbamazepine) may significantly decrease plasma concentrations of sofosbuvir, velpatasvir, and/or voxilaprevir leading to reduced therapeutic effect of VOSEVI. Anticonvulsants: carbamazepine phenytoin phenobarbital ↓ sofosbuvir ↓ velpatasvir ↓ voxilaprevir Coadministration is not recommended.

Epclusa
Carbamazepine is a medicine used to control seizures and treat nerve pain. It works by reducing abnormal electrical activity in the brain and calming nerve signals.
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.
Carbamazepine is used to treat certain types of seizures, including partial seizures and generalized tonic-clonic seizures. It can also treat mixed seizure patterns. Carbamazepine also treats the pain from trigeminal neuralgia, a nerve disorder that causes intense facial pain. It is also sometimes used for glossopharyngeal neuralgia.
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).
Carbamazepine is an anticonvulsant. It works by reducing the spread of seizure activity in the brain. It also stabilizes nerve impulses to reduce pain.
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.

Carbamazepine can cause severe skin reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), which can be fatal. If you are of Asian descent, you may need a blood test before starting this medicine. Carbamazepine can also cause serious blood problems like aplastic anemia and agranulocytosis. Contact your doctor right away if you develop a fever, sore throat, rash, or unusual bleeding or bruising.
Vosevi 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. Before starting Vosevi, your doctor will test you for Hepatitis B. They will also monitor you during and after treatment.

How to Read This carbamazepine vs sofosbuvir/velpatasvir Comparison
carbamazepine is classified in the Anticonvulsant 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, carbamazepine has 15,573 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 moderate interaction flagged in FDA labeling, attributed to carbamazepine can cause your body to break down this medicine too quickly, which makes the treatment less effective at fighting the virus.. 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 carbamazepine or sofosbuvir/velpatasvir.
