Drug & supplement interaction

Yohimbe + Levodopa

Levodopa brand names: Larodopa, Inbrija.

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 Yohimbe and Levodopa 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

Yohimbe and Levodopa

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 Levodopa and Yohimbe 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 Levodopa

Interactions in our licensed database are recorded against drug classes, not just single drug names. Levodopa is filed under 5 classifications — including dopamine agonists, seizure threshold lowering drugs, oral drugs. Yohimbe has documented interactions with 13 drug classes — the most serious being monoamine oxidase inhibitors (maois) (major), antihypertensive drugs (moderate) and clonidine (catapres) (moderate) — and none of Levodopa’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.

Keep it in perspective

Yohimbe Does Interact With Other Medications

Yohimbe has 9 major, 680 moderate, 436 minor known drug interactions in our database — Levodopa isn’t one of them. If you take anything else, check it against the full list below.

What to actually watch for

No Interaction Found — But Data Suggests Yohimbe and Levodopa 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    Yohimbe

    “Orally, yohimbine, a constituent of yohimbe, may cause bronchospasm, tachypnea, cough, and rhinorrhea. A case of sinusitis characterized by pain and discomfort above both eyes has been reported for a 59-year-old male taking yohimbine 5.4 mg three times daily to treat erectile dysfunction. Symptoms resolved within 24 hours of discontinuing yohimbine.”

From our pharmacist’s overview on the Levodopa page

“Parkinson symptoms return fast when levodopa (Larodopa, Inbrija) stops reaching the brain, and most of the 41 supplements on this page can make that happen, so treat these combinations with genuine care. Protein and amino acid supplements compete with levodopa for transport into the brain, while everyday minerals like magnesium and iro…”

About Yohimbe

What is Yohimbe?

Yohimbe
  • Erectile dysfunction
  • Low sex drive
  • Sexual performance
  • Weight loss
  • Athletic performance

Yohimbe is a West African tree bark that contains yohimbine, a compound mainly promoted for erectile dysfunction and as an aphrodisiac. A prescription form of yohimbine has some evidence for erectile dysfunction, but over-the-counter yohimbe supplements vary widely in content and can cause serious side effects like high blood pressure and fast heart rate. Because of these safety concerns, talk to your pharmacist or doctor before using it.

Pausinystalia johimbe · Rubiaceae · Bark · Capsules, tablets, extracts, teas

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

Yohimbe: dosing

There is no well-established safe and standardized dose for yohimbe bark supplements. Because the yohimbine content varies so much between products, the same labeled dose can produce very different effects.If you choose to use a product, follow the directions on the label and do not exceed them. Prescription yohimbine is a separate, dose-controlled medicine and should only be used as directed by a healthcare provider.

About Levodopa Oral Inhalation

What Is Levodopa Oral Inhalation Used For?

Brand names: Larodopa, Inbrija

Inbrija is used to treat OFF episodes in adults with Parkinson's disease. An OFF episode is when your regular oral carbidopa/levodopa medication temporarily stops working well enough, causing Parkinson's symptoms — such as stiffness, slowness, or tremor — to return.

Inbrija is used as needed when OFF symptoms start to come back. It is not a replacement for your regular oral carbidopa/levodopa; it works alongside it.

Most-Reported Side Effects for Levodopa

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Yohimbe and Levodopa Together: Common Questions

Is it safe to take Yohimbe with Levodopa?
We do not list a known interaction between Yohimbe and Levodopa. 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 Yohimbe and Levodopa have any of the same side effects?
Yes — our sources link each of them separately to 7 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 Yohimbe and Levodopa combination checked?
Interactions in our licensed database are recorded against drug classes. Levodopa is filed under 5 classifications, and Yohimbe has documented interactions with 13 drug classes — none of Levodopa'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 Yohimbe interact with any other medications?
Yes. Yohimbe has 1,125 documented drug interactions in our database — Levodopa 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 Levodopa interact with any supplements?
Yes. Levodopa has documented interactions with 41 supplements in our database — Yohimbe is not one of them. The Levodopa interaction page linked on this page lists every one, ranked by severity.
