Drug & supplement interaction

Devil's Claw + Lisdexamfetamine

Lisdexamfetamine brand name: Vyvanse.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Devil's Claw and Lisdexamfetamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Devil's Claw and Lisdexamfetamine

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 Lisdexamfetamine and Devil's Claw 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 Lisdexamfetamine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lisdexamfetamine is filed under 6 classifications — including amphetamines, stimulant drugs, serotonergic drugs. Devil's Claw has documented interactions with 7 drug classes — the most serious being cytochrome p450 2c19 (cyp2c19) substrates (moderate), cytochrome p450 2c9 (cyp2c9) substrates (moderate) and cytochrome p450 3a4 (cyp3a4) substrates (moderate) — and none of Lisdexamfetamine’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

No Interaction Found — But Data Suggests Devil's Claw and Lisdexamfetamine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Raised blood pressure Worth acting on Additional detail

    Devil's Claw

    “In one case report, a healthy patient with normal blood pressure presented with hypertension after taking devil's claw 250 mg twice daily for 2 weeks. It gradually resolved after discontinuation of devil's claw. Some animal research shows that devil's claw might have negative chronotropic, as well as positive and negative inotropic, effects. However, these effects have not been documented in humans.”

About Devil's Claw

What is Devil's Claw?

Devil's Claw
  • Osteoarthritis pain
  • Lower back pain
  • Joint pain and stiffness
  • General inflammation
  • Digestive upset and loss of appetite

Devil's claw is a southern African plant used mainly for arthritis and back pain, and some studies suggest it may help ease these types of discomfort. The evidence is moderate at best, and product strength varies, so talk with your pharmacist or doctor before trying it, especially if you have a health condition or take medications.

Harpagophytum procumbens · Pedaliaceae · Dried secondary (tuberous) roots · Capsules, tablets, dried root, tea, liquid extracts, and tinctures

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

Devil's Claw: dosing

There is no single official dose for devil's claw. Many products are standardized to their harpagoside content, but the amount varies a lot from one brand to another.The safest approach is to follow the directions on the product label and not take more than recommended.

Taking Devil's Claw and Lisdexamfetamine Together: Common Questions

Is it safe to take Devil's Claw with Lisdexamfetamine?
We do not list a known interaction between Devil's Claw and Lisdexamfetamine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Devil's Claw and Lisdexamfetamine have any of the same side effects?
Yes — our sources link each of them separately to 10 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Devil's Claw and Lisdexamfetamine combination checked?
Interactions in our licensed database are recorded against drug classes. Lisdexamfetamine is filed under 6 classifications, and Devil's Claw has documented interactions with 7 drug classes — none of Lisdexamfetamine's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Devil's Claw interact with any other medications?
Yes. Devil's Claw has 804 documented drug interactions in our database — Lisdexamfetamine is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Lisdexamfetamine interact with any supplements?
Yes. Lisdexamfetamine has documented interactions with 126 supplements in our database — Devil's Claw is not one of them. The Lisdexamfetamine interaction page linked on this page lists every one, ranked by severity.
