Drug & supplement interaction

Lorenzo's Oil + Gabapentin

Gabapentin brand names: Neurontin, Gralise.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Lorenzo's Oil and Gabapentin 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.

Lorenzo's Oil and Gabapentin

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 Gabapentin 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 Gabapentin, 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.

No Interaction Found — But Data Suggests Lorenzo's Oil and Gabapentin May Share a Side Effect

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. One of them is worth acting on rather than waiting out — marked below.

From our pharmacist’s overview on the Gabapentin page

“Gabapentin (Neurontin, Gralise) calms overactive nerves, which means it already slows your nervous system down, and that is exactly what 78 of the 106 supplements on this list also do. So the dominant risk here is sedation stacked on sedation, extra drowsiness at best and dangerously slowed breathing at worst, and with seven entries ra…”

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. Do not use it as a casual supplement.

About Gabapentin

What Is Gabapentin Used For?

Brand names: Neurontin, Gralise

Gabapentin (brands include Neurontin, Relgaabi, Gabarone, Gralise, and Horizant) is primarily used to manage postherpetic neuralgia (PHN) — the nerve pain that lingers after a shingles outbreak — in adults. Neurontin, Relgaabi, Gabarone, and gabapentin capsules, tablets, and oral solution are also used as add-on therapy for partial onset seizures (a type of epilepsy) in adults and children aged 3 and older.

Horizant (gabapentin enacarbil extended-release tablet) has two specific approvals: treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults, and management of postherpetic neuralgia in adults. Horizant is not recommended for people who need to sleep during the day and stay awake at night. Gralise is approved only for postherpetic neuralgia and cannot be substituted for other gabapentin products due to its different release profile.

Most-Reported Side Effects for Gabapentin

From FAERS, the FDA’s public side-effect reporting system (361,481 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Fatigue 24,972 reports

Taking Lorenzo's Oil and Gabapentin Together: Common Questions

Is it safe to take Lorenzo's Oil with Gabapentin?
We do not list a known interaction between Lorenzo's Oil and Gabapentin. 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 Lorenzo's Oil and Gabapentin have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Does Gabapentin interact with any supplements?
Yes. Gabapentin has documented interactions with 106 supplements in our database — Lorenzo's Oil is not one of them. The Gabapentin interaction page linked on this page lists every one, ranked by severity.
