Jamaican Dogwood and Sofosbuvir

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 and Jamaican Dogwood 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

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sofosbuvir is filed under 4 classifications — including p-glycoprotein substrates, oral drugs. Jamaican Dogwood has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Sofosbuvir’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 Sofosbuvir’s Own FDA Label Lists

This is not an interaction — none of it involves Jamaican Dogwood. These are the most notable effects listed in the ADVERSE REACTIONS section of Sofosbuvir’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 2 of them are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on
  • Anemia Worth acting on
  • Tiredness mentioned in 17.7% of FDA reports for Sofosbuvir
  • Trouble sleeping mentioned in 4.7% of FDA reports for Sofosbuvir
  • Reduced appetite
  • Headache mentioned in 14.7% of FDA reports for Sofosbuvir
  • Nausea mentioned in 7.5% of FDA reports for Sofosbuvir

From the ADVERSE REACTIONS section of the FDA label for Sofosbuvir. Read the label on DailyMed › Where a percentage is shown, it is the share of 52,253 voluntary FDA FAERS reports for Sofosbuvir that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Jamaican Dogwood’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Jamaican Dogwood side to compare — that is a limit of the record, not a statement that Jamaican Dogwood has no side effects.

From our pharmacist’s overview on the Sofosbuvir page

“Sofosbuvir (Sovaldi) cures hepatitis C over a fixed course, so a supplement that lowers its blood level risks more than a side effect; it can let the virus survive treatment. The two major-rated interactions among the 55 ingredients here do exactly that: St.”

About Jamaican Dogwood

What is Jamaican Dogwood?

  • Insomnia and sleep trouble
  • Nerve pain
  • Anxiety and tension
  • Menstrual cramps
  • Muscle pain and spasms
  • Migraine and headaches

Jamaican dogwood is a tree bark traditionally used to promote sleep and ease pain, but high-quality human studies are lacking. It can be toxic in larger amounts and should be used cautiously, if at all, and never during pregnancy or breastfeeding. Talk to a pharmacist or doctor before trying it.

Piscidia piscipula · Fabaceae · Bark of the root and stem · Dried bark, tinctures, liquid extracts, capsules, teas

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

Jamaican Dogwood: dosing

There is no well-established, standardized dose for Jamaican dogwood. Products vary widely in strength, and the bark's natural compounds can be potent, so there is no safe "recommended" amount we can confidently give.If you choose to use a product, follow the directions on the label exactly and do not exceed them. It is best to start any new supplement only after checking with a pharmacist or doctor, who can help you weigh the risks. Avoid using it long-term or in high amounts.

About Sofosbuvir

What Is Sofosbuvir Used For?

Brand name: Sovaldi

Sovaldi (sofosbuvir) is used to treat chronic hepatitis C virus (HCV) infection. In adults, it treats genotype 1, 2, 3, or 4 HCV — with or without compensated cirrhosis (mild liver scarring that the liver is still managing). It is always used as part of a combination regimen with other antiviral medicines.

In children 3 years and older, Sovaldi is approved for genotype 2 or 3 HCV, with or without compensated cirrhosis, in combination with ribavirin. Sovaldi is also used with ribavirin in adults with HCV-related liver cancer (hepatocellular carcinoma) who are waiting for a liver transplant, to help prevent HCV from returning after transplant.
