Black Nightshade 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 Black Nightshade 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Black Nightshade at all — not against Sofosbuvir, Velpatasvir, Voxilaprevir, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

How to take them

Some Sofosbuvir, Velpatasvir, Voxilaprevir Products Have a Food Rule — Black Nightshade 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 Black Nightshade 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.

Overlapping uses

What Sofosbuvir, Velpatasvir, Voxilaprevir Is Prescribed For, and What Black Nightshade Has Been Studied For

Sofosbuvir, Velpatasvir, Voxilaprevir is a prescription medicine with approved uses on its FDA label. Black Nightshade 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 without cirrhosis (liver scarring) or with compensated cirrhosis (mild liver scarring, Child-Pugh A). It is specifically for people who have already tried an HCV treatment that did not fully work. Vosevi is approved for adults with HCV genotypes 1, 2, 3, 4, 5, or 6 who were previously treated with a regimen containing an NS5A inhibitor. It is also approved for adults with genotype 1a or 3 who were previously treated with sofosbuvir without an NS5A inhibitor.

Note: Vosevi has not been shown to offer additional benefit over sofosbuvir/velpatasvir for adults with genotype 1b, 2, 4, 5, or 6 who received sofosbuvir without an NS5A inhibitor.

Black Nightshade has been studied for:

  • Cirrhosis studied, not established Black Nightshade has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Black Nightshade for cirrhosis

    Although there is interest in using oral black nightshade for cirrhosis, there is insufficient reliable information about the clinical effects of black nightshade for this condition.

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 Black Nightshade 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 Black Nightshade

What is Black Nightshade?

Black Nightshade
  • Digestive complaints
  • Skin conditions
  • Inflammation
  • Fever
  • Liver support (traditional)

Black nightshade is a wild plant whose cooked ripe berries and leaves are eaten as food in some cultures, but unripe berries and green parts can be poisonous. Human evidence for any health benefit is very limited, and the risk of toxicity is real. Do not use it as a supplement without medical guidance, and avoid it during pregnancy and breastfeeding.

Solanum nigrum · Solanaceae · Leaves, berries (ripe), and whole plant · Cooked leafy greens, fruit, traditional decoctions, dried herb, extracts

An interaction check asks whether these two react with each other — it does not ask whether Black Nightshade is a good idea for someone in your situation. Here is what our Black Nightshade record says about it on its own.

Black Nightshade: dosing

There is no established or standardized safe dose of black nightshade as a supplement. When it comes to wild plants, never guess at an amount or forage your own to use as medicine.
