Delta-8-tetrahydrocannabinol (delta-8-thc) + Sodium Oxybate

Sodium Oxybate brand name: Xyrem.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate 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 Sodium Oxybate states a food rule worth keeping to, and 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.

Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate

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 Sodium Oxybate and Delta-8-tetrahydrocannabinol (delta-8-thc) 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 Delta-8-tetrahydrocannabinol (delta-8-thc) at all — not against Sodium Oxybate, 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.

What to actually watch for

No Interaction Found — But Data Suggests Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate 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.

  • Drowsiness reported in 6.0% of FDA reports for Sodium Oxybate Additional detail

    Delta-8-tetrahydrocannabinol (delta-8-thc)

    “A large case series reports pulmonary disorders (e.g., cough, dry throat, dyspnea, painful respiration) as some of the most frequently noted adverse effects with delta-8-THC after assessing a public forum of 98,700 subscribers. Of 183 adverse events related to delta-8-THC reported to the US Food and Drug Administration, 33 report dyspnea, 17 report respiratory disorder, and 15 report cough.”

    Sodium Oxybate

    Listed in the ADVERSE REACTIONS section of the FDA label for Sodium Oxybate. Read the label on DailyMed ›

Reported for Delta-8-tetrahydrocannabinol (delta-8-thc) but not commonly for Sodium Oxybate: a slow heartbeat, shortness of breath, low blood pressure and hallucinations.

Effects for Sodium Oxybate come from the ADVERSE REACTIONS section of its FDA label; effects for Delta-8-tetrahydrocannabinol (delta-8-thc) come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 65,315 voluntary FDA FAERS reports for Sodium Oxybate that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Sodium Oxybate Products Have a Food Rule — Delta-8-tetrahydrocannabinol (delta-8-thc) Should Not Break It

At least one FDA label for a product containing Sodium Oxybate says to take it with food. If you take Delta-8-tetrahydrocannabinol (delta-8-thc) on an empty stomach out of habit, keep them separate — and take Sodium Oxybate with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Sodium Oxybate 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.

• Allow 2 hours after eating before dosing ( 2.3 ).

From the Dosage and Administration section of the FDA label we read for Sodium Oxybate — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

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.

Everything else you take

See Every Supplement That Interacts With Sodium Oxybate

This page covers Delta-8-tetrahydrocannabinol (delta-8-thc) only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sodium Oxybate page lists 25 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Biofeedback (moderate), Coffee Charcoal (moderate), Dendrobium (moderate) and European Mandrake (moderate).

By severity: 1 major · 15 moderate · 9 minor.

From our pharmacist’s overview on the Sodium Oxybate page

“Activated charcoal is the single major-rated interaction with sodium oxybate (Xyrem), and it earns that rating because the drug only works if each dose is fully absorbed; charcoal can bind it in the gut and weaken the nighttime control it provides for narcolepsy. Treat this list with genuine care, since 17 of the 25 ingredients on file…”

About Delta-8-tetrahydrocannabinol (delta-8-thc)

What is Delta-8-tetrahydrocannabinol (delta-8-thc)?

  • Relaxation and mild euphoria
  • Anxiety and stress
  • Sleep problems
  • Pain relief
  • Nausea
  • Appetite stimulation

Delta-8-THC is a mind-altering cannabis compound, usually made by chemically converting CBD from hemp, that produces effects similar to but often milder than regular (delta-9) THC. There is very little quality human research on its benefits, and the FDA has warned about safety concerns, unregulated products, and reports of harm. Its legal status varies, and it is not recommended during pregnancy, breastfeeding, or for people who must avoid intoxication.

Cannabinoid derived from hemp (Cannabis sativa) · Gummies, vape cartridges, tinctures, edibles, capsules, flower sprayed with extract

An interaction check asks whether these two react with each other — it does not ask whether Delta-8-tetrahydrocannabinol (delta-8-thc) is a good idea for someone in your situation. Here is what our Delta-8-tetrahydrocannabinol (delta-8-thc) record says about it on its own.

Delta-8-tetrahydrocannabinol (delta-8-thc): dosing

There is no established or standardized safe dose for delta-8-THC. Products vary widely in strength, and because the market is poorly regulated, the amount listed on the label may not match what is actually in the product.If a product is used, the general harm-reduction advice is to "start low and go slow," follow the product label, and wait long enough to feel the effects—edibles in particular can take a couple of hours to kick in, leading some people to take too much.

About Sodium Oxybate

What Is Sodium Oxybate Used For?

Brand name: Xyrem

Sodium oxybate treats two major symptoms of narcolepsy: cataplexy (sudden muscle weakness triggered by emotion) and excessive daytime sleepiness (EDS). It is available in several products, each approved for these uses.

Xyrem (oral solution) and the generic sodium oxybate oral solution are approved for cataplexy or EDS in patients with narcolepsy. Lumryz (extended-release oral suspension) is specifically approved for cataplexy or EDS in patients 7 years of age and older with narcolepsy. The generic sodium oxybate oral solution label does not include the pediatric indication due to marketing exclusivity held by Xyrem.

Most-Reported Side Effects for Sodium Oxybate

From FAERS, the FDA’s public side-effect reporting system (65,536 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Nausea 4,928 reports
Anxiety 3,979 reports
Somnolence 3,965 reports
Insomnia 3,371 reports
Feeling abnormal 3,223 reports

Taking Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate Together: Common Questions

Is it safe to take Delta-8-tetrahydrocannabinol (delta-8-thc) with Sodium Oxybate?
We do not list a known interaction between Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate. 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 Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate have any of the same side effects?
Yes — our sources link each of them separately to 4 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.
Should I take Delta-8-tetrahydrocannabinol (delta-8-thc) and Sodium Oxybate at the same time of day?
At least one FDA label for a product containing Sodium Oxybate says to take it with food. If you take Delta-8-tetrahydrocannabinol (delta-8-thc) on an empty stomach out of habit, keep them separate and take Sodium Oxybate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Sodium Oxybate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
Does Sodium Oxybate interact with any supplements?
Yes. Sodium Oxybate has documented interactions with 25 supplements in our database — Delta-8-tetrahydrocannabinol (delta-8-thc) is not one of them. The Sodium Oxybate interaction page linked on this page lists every one, ranked by severity.
