Scopolia and Sofosbuvir, Velpatasvir

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 and Scopolia 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.

How we checked

Why No Interaction Is Listed for Sofosbuvir, Velpatasvir

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sofosbuvir, Velpatasvir is filed under 7 classifications — including cytochrome p450 2b6 (cyp2b6) substrates, cytochrome p450 2c8 (cyp2c8) substrates, p-glycoprotein substrates. Scopolia has documented interactions with 3 drug classes — the most serious being anticholinergic drugs (major), quinidine (major) and tricyclic antidepressants (tcas) (major) — and none of Sofosbuvir, Velpatasvir’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.

What to actually watch for

What Scopolia Itself Has Been Linked To

This is not an interaction — nothing below involves Sofosbuvir, Velpatasvir. It is the side-effect record for Scopolia on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Scopolia, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Trouble passing urine / Hallucinations / Confusion Worth acting on Additional detail

    “Scopolia is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity. Orally, scopolia root acts on the central nervous system and can cause dry mouth, dry and reddened skin, hyperthermia, disturbance of ocular accommodation, tachycardia, difficulty urinating, glaucoma attacks (2), and constipation (18).”

Everything above comes from the Natural Medicines adverse-effect record for Scopolia — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Sofosbuvir, Velpatasvir’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Sofosbuvir, Velpatasvir column appears here.

From our pharmacist’s overview on the Sofosbuvir, Velpatasvir page

“Epclusa (the sofosbuvir and velpatasvir combination) is a finite course meant to cure hepatitis C, so I treat its supplement interactions with genuine seriousness, since anything that lowers the drug's level can undermine the cure itself. St.”

About Scopolia

What is Scopolia?

Scopolia
  • Stomach and intestinal cramps
  • Motion sickness
  • Spasms and colic
  • Excess saliva or secretions
  • Pain relief (traditional)

Scopolia is a poisonous plant in the nightshade family that contains powerful anticholinergic alkaloids like atropine, hyoscyamine, and scopolamine. While these compounds are used in carefully measured prescription medicines, the raw plant is dangerous for self-treatment and should never be used without a doctor's supervision.

Scopolia carniolica · Solanaceae · Rhizome (root) and leaves · Standardized extracts, tinctures, and as a source for isolated alkaloid drugs (rarely sold as a stand-alone supplement)

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

Scopolia: dosing

There is no established safe over-the-counter dose of Scopolia for self-care. Because the plant contains powerful and toxic alkaloids, even small differences in amount can be the difference between an effect and a poisoning.The purified alkaloids found in Scopolia are dosed precisely in prescription products by trained professionals. When in doubt, do not use it.
