Aloe and Sofosbuvir, Velpatasvir, Voxilaprevir

Here is the interaction we found between these two, with the evidence behind it.

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Sofosbuvir, Velpatasvir, Voxilaprevir

Sofosbuvir, Velpatasvir, Voxilaprevir falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Aloe interacts with.

Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that aloe extract 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 honest picture: the concern on file is that aloe taken by mouth might speed up a liver enzyme called CYP1A2, which could in theory lower the levels of your hepatitis C medicine (Vosevi). But this idea comes only from lab and animal studies, not from real people, so it's very much a theoretical worry rather than a proven one.

That said, the goal with Vosevi is to fully clear the hepatitis C virus, and anything that lowers its levels could, at least on paper, make treatment less effective. Because finishing this course successfully really matters, I'd skip oral aloe (the laxative kind) while you're on it. Aloe gel used on the skin isn't a concern here. Please check with your pharmacist or doctor before adding anything new.

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 Aloe

What is Aloe?

Aloe
  • Minor burns and skin irritation
  • Wound healing

  • Digestive complaints
  • Hair and scalp care

Aloe vera gel is widely used on the skin for minor burns and irritation, and some research suggests it may help. Aloe latex (the yellow part) is a strong laxative that can cause cramping and is not considered safe for regular use. Talk to your pharmacist or doctor before taking aloe by mouth, and avoid oral aloe during pregnancy.
