Mountain Flax + Oliceridine
Oliceridine brand name: Olinvyk.
We found no known interaction between Mountain Flax and Oliceridine 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.
Mountain Flax and Oliceridine
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 Oliceridine and Mountain Flax 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 Mountain Flax at all — not against Oliceridine, 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.

About Mountain Flax
What is Mountain Flax?
- Constipation
- Laxative/purgative
- Liver and digestive complaints
- Joint and rheumatic discomfort
- Traditional 'cleansing' remedies
Mountain Flax (Linum catharticum) is a small wild flax once used in traditional European herbalism mainly as a strong laxative or purgative. There is very little modern scientific evidence to support its use, and it can be harsh on the gut, so it is rarely recommended today. If you are considering any herbal laxative, talk to your pharmacist or doctor first.
Linum catharticum · Linaceae · Whole flowering plant (dried aerial parts) · Dried herb, tea/infusion, tincture (rare today)
An interaction check asks whether these two react with each other — it does not ask whether Mountain Flax is a good idea for someone in your situation. Here is what our Mountain Flax record says about it on its own.
Mountain Flax: dosing
There is no established or standardized dose for Mountain Flax, and it is not a common modern product. Older herbal traditions used small amounts of the dried plant as a tea, but exact safe amounts have not been studied.Because of this uncertainty and its strong purgative effect, we cannot recommend a specific dose.

About Oliceridine Injection
What Is Oliceridine Injection Used For?
Brand name: Olinvyk
Olinvyk (oliceridine) injection is approved for adults to manage acute pain that is severe enough to require an intravenous opioid analgesic. It is used only when alternative treatments are ineffective, not tolerated, or otherwise unable to provide adequate pain control.
Because of serious risks including addiction, misuse, overdose, and death, Olinvyk is reserved for situations where other pain management options are not sufficient. It is not intended for routine or chronic pain management.
