Beet and Sofosbuvir, Velpatasvir, Voxilaprevir

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Beet interacts with whole categories of medication. Sofosbuvir, Velpatasvir, Voxilaprevir falls into 2 of those categories, so it can interact with Beet in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Sofosbuvir, Velpatasvir, Voxilaprevir

Sofosbuvir, Velpatasvir, Voxilaprevir falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Beet interacts with.

Theoretically, beet might increase the levels of CYP3A4 substrates.
In vitro research suggests that betanin, the major pigment in beet, competitively inhibits CYP3A4 in a dose-dependent manner similarly to strong CYP3A4 inhibitor ketoconazole.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Vosevi (sofosbuvir, velpatasvir, voxilaprevir). One pigment in beets, called betanin, was shown in a lab dish to block an enzyme called CYP3A4, which helps your body clear part of this combination (voxilaprevir in particular). In theory, slowing that enzyme could let drug levels drift up a bit, which might mean more of the usual side effects like headache, tiredness, nausea, or diarrhea.

The honest part: this is only test-tube data, not something seen in real patients, so I wouldn't lose sleep over it. Eating beets as food is very unlikely to cause trouble. Concentrated beet supplements are a bigger unknown. If you want to use them during your hepatitis C treatment, just run it by your pharmacist or doctor first.

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

2 of 2

Sofosbuvir, Velpatasvir, Voxilaprevir also falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES.

Theoretically, beet might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research suggests that beet induces CYP1A2 enzymes.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version on combining beetroot with Vosevi (sofosbuvir, velpatasvir, voxilaprevir): there isn't much to worry about. The concern on file is theoretical and comes only from lab studies, not from people taking the two together. The idea is that beet might gently speed up an enzyme called CYP1A2, which could in turn lower drug levels. But these three hepatitis C medicines are not mainly cleared by CYP1A2, so this pathway has little real impact on them.

Eating beets or drinking beetroot juice as food is very unlikely to cause a problem here. Concentrated beet supplements haven't been shown to weaken Vosevi either. Still, since finishing your full course matters for clearing the virus, it's smart to run any new supplement past your pharmacist or doctor.

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.”
