Drug & supplement interaction

Dodder + 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 Dodder 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.

Dodder 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 Dodder 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Dodder at all — not against Lisdexamfetamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Dodder overall Use caution Human safety data are limited, so use cautiously and under guidance from a healthcare professional.
Pregnancy Avoid Not enough safety information exists, so it is best avoided during pregnancy.

What to actually watch for

No Interaction Found — But Data Suggests Dodder 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.

  • Reduced appetite Additional detail

    Dodder

    “Orally, a combination of whey and dodder seed extract has been reported to cause anorexia, mild dyspepsia, and feelings of stomach heaviness. It is not known if these symptoms are related to whey, dodder, or the combination. Intestinal colic and diarrhea have been reported as possible symptoms of dodder overdose. Traditional sources suggest a maximum daily dose of 8 grams of dodder aerial parts.”

About Dodder

What is Dodder?

Dodder
  • Sexual health and impotence
  • Energy and fatigue
  • Kidney and reproductive support (in traditional medicine)
  • Eye health and vision
  • Liver support

Dodder (Cuscuta) is a parasitic plant whose seeds are used in traditional Chinese and Middle Eastern medicine, mainly for sexual, kidney, and energy-related complaints. Human evidence for any of these uses is very limited, and safety has not been well studied, so talk with your pharmacist or doctor before trying it.

Cuscuta chinensis · Convolvulaceae · Seeds (and sometimes the whole vine) · Dried seeds, powders, capsules, tinctures, teas, and ingredients in traditional Chinese herbal formulas

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

Dodder: dosing

There is no well-established, standardized dose of dodder for any health condition. Traditional formulas vary widely, and the strength of commercial products differs from brand to brand.If you choose to use a dodder product, follow the directions on the label and do not exceed the recommended amount.

Taking Dodder and Lisdexamfetamine Together: Common Questions

Is it safe to take Dodder with Lisdexamfetamine?

Do Dodder and Lisdexamfetamine have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other.
