Choline + Sofosbuvir, Velpatasvir, Voxilaprevir
Sofosbuvir, Velpatasvir, Voxilaprevir brand name: Vosevi.
We found no known interaction between Choline and Sofosbuvir, Velpatasvir, Voxilaprevir in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Sofosbuvir, Velpatasvir, Voxilaprevir states a food rule worth keeping to, and the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Choline and Sofosbuvir, Velpatasvir, Voxilaprevir
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Sofosbuvir, Velpatasvir, Voxilaprevir and Choline in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
Choline safety at a glance
Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Sofosbuvir, Velpatasvir, Voxilaprevir
Interactions in our licensed database are recorded against drug classes, not just single drug names. Sofosbuvir, Velpatasvir, Voxilaprevir is filed under 9 classifications — including cytochrome p450 2b6 (cyp2b6) substrates, cytochrome p450 2c8 (cyp2c8) substrates, cytochrome p450 1a2 (cyp1a2) substrates. Choline has documented interactions with 1 drug class — the most serious being atropine (minor) — and none of Sofosbuvir, Velpatasvir, Voxilaprevir’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.
Choline Does Interact With Other Medications
Choline has 16 minor known drug interactions in our database — Sofosbuvir, Velpatasvir, Voxilaprevir isn’t one of them. If you take anything else, check it against the full list below.

Choline in Pregnancy & Breastfeeding
When used orally and appropriately. Choline is safe when taken in doses below the tolerable upper intake level (UL), which is 3 grams daily during pregnancy and lactation in those up to 18 years of age and 3.5 grams daily for those 19 years and older. There is insufficient reliable information available about the safety of choline used in higher doses during pregnancy and lactation.

Some Sofosbuvir, Velpatasvir, Voxilaprevir Products Have a Food Rule — Choline Should Not Break It
At least one FDA label for a product containing Sofosbuvir, Velpatasvir, Voxilaprevir says to take it with food. If you take Choline on an empty stomach out of habit, keep them separate — and take Sofosbuvir, Velpatasvir, Voxilaprevir with a meal where the label says to.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Sofosbuvir, Velpatasvir, Voxilaprevir products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
( 2.1 ) Recommended dosage: One tablet (400 mg of sofosbuvir, 100 mg of velpatasvir, and 100 mg of voxilaprevir) taken orally once daily with food.
From the Dosage and Administration section of the FDA label we read for Sofosbuvir, Velpatasvir, Voxilaprevir — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.
What Sofosbuvir, Velpatasvir, Voxilaprevir Is Prescribed For, and What Choline Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Sofosbuvir, Velpatasvir, Voxilaprevir is a prescription medicine with approved uses on its FDA label. Choline is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Sofosbuvir, Velpatasvir, Voxilaprevir is prescribed for: Vosevi is used to treat chronic hepatitis C virus (HCV) infection in adults who do not have cirrhosis or who have compensated cirrhosis (mild liver scarring that is still functioning). It is specifically for people who have already been treated with an HCV regimen before and need a different option. Vosevi is approved for adults with HCV genotype 1, 2, 3, 4, 5, or 6 who previously took a medicine that included an NS5A inhibitor. It is also approved for adults with genotype 1a or 3 who previously took sofosbuvir without an NS5A inhibitor.
Choline has been studied for:
-
Hepatitis studied, not established Choline has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Choline for hepatitis
Although there has been interest in using oral choline for hepatitis, there is insufficient reliable information about the clinical effects of choline for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Sofosbuvir, Velpatasvir, Voxilaprevir on your own; if you are taking Choline for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Sofosbuvir, Velpatasvir, Voxilaprevir page
“Vosevi (sofosbuvir, velpatasvir, and voxilaprevir) cures hepatitis C over a single short course, and that is exactly why I would be genuinely careful with supplements while taking it. Anything that drags its blood levels down can cost you the cure itself.”

About Choline
What is Choline?
- Liver health and fatty liver
- Brain and memory support
- Prenatal nutrition and fetal development
- General nutritional supplementation
- Sports performance
Choline is an essential nutrient your body needs for liver function, brain health, and nerve signaling, and many people get enough from foods like eggs, meat, and fish. Supplements may help people who are deficient or who have higher needs (such as during pregnancy), but they are not proven cure-alls and very high doses can cause side effects. Check with your pharmacist or doctor before starting a supplement.
Not applicable (an essential nutrient found in foods and made in the body) · Capsules, tablets, softgels, and powders; common forms include choline bitartrate, choline chloride, phosphatidylcholine, alpha-GPC, and CDP-choline (citicoline)
An interaction check asks whether these two react with each other — it does not ask whether Choline is a good idea for someone in your situation. Here is what our Choline record says about it on its own.
Choline: dosing
There is no single "treatment" dose of choline that works for everyone, and the right amount depends on your age, sex, life stage, and diet. Health authorities have set recommended adequate intake levels for daily choline as well as a daily upper limit, but these are general nutrition guides rather than doses for treating any condition.Supplements come in different strengths and forms, and the amount of actual choline varies by form.
