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

We found no known interaction between Theacrine 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.

Theacrine 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 Theacrine 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.

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.

Theacrine safety at a glance

Theacrine overall Use caution Short-term use appears generally well tolerated in studies, but long-term safety is not well established.
Pregnancy Avoid Not enough safety data, so avoid use during pregnancy.
Breastfeeding Avoid Not enough safety data, so avoid use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Sodium Oxybate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sodium Oxybate is filed under 3 classifications — sodium-containing drugs, seizure threshold lowering drugs, oral drugs. Theacrine has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Sodium Oxybate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Sodium Oxybate’s Own FDA Label Lists

This is not an interaction — none of it involves Theacrine. These are the most notable effects listed in the ADVERSE REACTIONS section of Sodium Oxybate’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. One of them is worth acting on rather than waiting out — marked below.

  • Low mood Worth acting on
  • Weight loss
  • Tremor or shakiness
  • Drowsiness mentioned in 6.0% of FDA reports for Sodium Oxybate
  • Dry mouth
  • Reduced appetite
  • Stomach pain
  • Dizziness
  • Nausea mentioned in 7.5% of FDA reports for Sodium Oxybate
  • Headache mentioned in 4.9% of FDA reports for Sodium Oxybate

Showing the 10 most notable of 12 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Sodium Oxybate. Read the label on DailyMed › 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. Theacrine’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Theacrine side to compare — that is a limit of the record, not a statement that Theacrine has no side effects.

How to take them

Some Sodium Oxybate Products Have a Food Rule — Theacrine Should Not Break It

At least one FDA label for a product containing Sodium Oxybate says to take it with food. If you take Theacrine 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 Theacrine 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 Theacrine

What is Theacrine?

  • Energy and reduced fatigue
  • Focus and mental alertness
  • Mood support
  • Pre-workout performance
  • Caffeine-like stimulation with possibly less tolerance

Theacrine is a caffeine-like compound found naturally in certain tea plants and is sold in supplements for energy, focus, and mood. Early human studies suggest it may give a stimulant-like boost, but the overall evidence is limited and long-term safety is not well known. Talk with your pharmacist or doctor before using it, especially if you are sensitive to stimulants or have heart problems.

Leaves (and a synthetic version is also made) · Capsules, tablets, powders (often in pre-workout and energy blends)

An interaction check asks whether these two react with each other — it does not ask whether Theacrine is a good idea for someone in your situation. Here is what our Theacrine record says about it on its own.

Theacrine: dosing

There is no officially established or standardized dose for theacrine. Amounts used in supplements vary, and it is often combined with caffeine and other ingredients in blends.The safest approach is to follow the directions on the product label and not exceed the recommended amount. Avoid taking it close to bedtime so it does not interfere with sleep.

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 Theacrine and Sodium Oxybate Together: Common Questions

Is it safe to take Theacrine with Sodium Oxybate?
We do not list a known interaction between Theacrine 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.
Should I take Theacrine 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 Theacrine 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.
How was the Theacrine and Sodium Oxybate combination checked?
Interactions in our licensed database are recorded against drug classes. Sodium Oxybate is filed under 3 classifications, and Theacrine has documented interactions with 1 drug class — none of Sodium Oxybate's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Theacrine interact with any other medications?
Yes. Theacrine has 248 documented drug interactions in our database — Sodium Oxybate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sodium Oxybate interact with any supplements?
Yes. Sodium Oxybate has documented interactions with 25 supplements in our database — Theacrine is not one of them. The Sodium Oxybate interaction page linked on this page lists every one, ranked by severity.
