Lorenzo's Oil + Naloxegol
Naloxegol brand name: Movantik.
We found no known interaction between Lorenzo's Oil and Naloxegol 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 label for Naloxegol states a food rule worth keeping to.
Lorenzo's Oil and Naloxegol
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 Naloxegol and Lorenzo's Oil 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 Lorenzo's Oil at all — not against Naloxegol, 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.
Lorenzo's Oil safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Naloxegol Products Have a Food Rule — Lorenzo's Oil Should Not Break It
At least one FDA label for a product containing Naloxegol says to take it on an empty stomach. Most supplements — Lorenzo's Oil included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Naloxegol on its own and move Lorenzo's Oil to a meal later in the day.
This may not be true of your version. Food instructions belong to the product, not the ingredient: two Naloxegol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.
(2.1) Take on an empty stomach at least 1 hour prior to the first meal of the day or 2 hours after the meal.
From the Dosage and Administration section of the FDA label we read for Naloxegol — where that label names a specific product, the instruction is that product's. See the Naloxegol drug page ›
A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Naloxegol page
“Naloxegol (Movantik) relieves the constipation that opioids cause, and this is a list that deserves real care before you add anything from it. Nearly all of the trouble traces to a single enzyme, CYP3A4, which the body relies on to clear naloxegol.”

About Lorenzo's Oil
What is Lorenzo's Oil?
- Adrenoleukodystrophy (ALD)
- Adrenomyeloneuropathy (AMN)
- Lowering very long-chain fatty acids in blood
- Slowing progression of certain inherited disorders
Lorenzo's Oil is not a typical herbal supplement—it is a specially formulated mixture of two fatty acids (glyceryl trioleate and glyceryl trierucate, in a 4:1 ratio) developed to lower very long-chain fatty acids in people with adrenoleukodystrophy (ALD). It can normalize blood fatty acid levels and may help delay disease in some boys who are not yet showing symptoms, but it is not a cure and should only be used under specialist medical supervision.
Refined plant-derived oils (rapeseed/olive oil sources) · Oral liquid oil (prescription-style medical formulation)
An interaction check asks whether these two react with each other — it does not ask whether Lorenzo's Oil is a good idea for someone in your situation. Here is what our Lorenzo's Oil record says about it on its own.
Lorenzo's Oil: dosing
There is no standard over-the-counter dose for Lorenzo's Oil. When used medically, the amount is calculated by a specialist based on the person's body and is adjusted using blood tests and a carefully controlled low-fat diet.Because dosing must be individualized and monitored, you should not try to dose this product yourself.
