Glucuronolactone + Papaverine
Papaverine brand names: Pavabid, Para Time, P 200, Pavabid HP.
We found no known interaction between Glucuronolactone and Papaverine 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.
Glucuronolactone and Papaverine
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 Papaverine and Glucuronolactone 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 Glucuronolactone at all — not against Papaverine, 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.
Glucuronolactone safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
See Every Supplement That Interacts With Papaverine
This page covers Glucuronolactone only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Papaverine page lists 20 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), American Mistletoe (major), Beer (moderate), Coffee Charcoal (moderate) and European Mandrake (moderate).
By severity: 2 major · 9 moderate · 9 minor.
From our pharmacist’s overview on the Papaverine page
“Papaverine relaxes blood vessels to improve blood flow, and its interaction list warrants genuine care, since 2 of the 20 entries are rated major. Most of the list concerns absorption, fibers and gums that can change how much of an oral dose reaches your bloodstream, but the two majors come first.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Glucuronolactone is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Glucuronolactone reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Glucuronolactone and Papaverine records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Glucuronolactone
What is Glucuronolactone?
- Energy and stamina
- Mental focus and alertness
- Reducing fatigue
- Athletic performance
- Detoxification support (traditional belief)
Glucuronolactone is a naturally occurring compound that is commonly added to energy drinks and supplements, often alongside caffeine and taurine. There is very little solid human evidence that it provides energy, focus, or other benefits on its own, and most studies tested it only as part of a combined product. It appears reasonably well tolerated at the amounts used in drinks, but its long-term safety and effects in pregnancy and breastfeeding are not well studied.
Not a plant; a manufactured/naturally occurring compound (D-glucuronolactone) · Energy drinks, capsules, powders, pre-workout blends
An interaction check asks whether these two react with each other — it does not ask whether Glucuronolactone is a good idea for someone in your situation. Here is what our Glucuronolactone record says about it on its own.
Glucuronolactone: dosing
There is no officially established or standardized dose of glucuronolactone for any health purpose. In energy drinks it commonly appears in amounts of a few hundred milligrams per serving, often alongside caffeine and taurine.Because a proven effective dose has not been identified, the best advice is to follow the product label and not exceed it.

About Papaverine
What Is Papaverine Used For?
Brand names: Pavabid, Para Time, P 200, Pavabid HP
Papaverine Hydrochloride Injection is used when smooth muscle goes into spasm — meaning it contracts abnormally and needs to be relaxed. It is given for vascular (blood vessel) spasms that can occur with conditions like acute myocardial infarction (heart attack), angina pectoris (chest pain from reduced blood flow to the heart), and peripheral or pulmonary embolism (blockages in the limb or lung arteries).
It is also used for peripheral vascular disease where spasm plays a role, certain cerebral angiospastic states (blood vessel spasms in the brain), and visceral spasm — meaning painful cramping in internal organs such as the ureter, gallbladder (biliary colic), or intestines (gastrointestinal colic).
