Drug & supplement interaction

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

We found no known interaction between Tartaric Acid 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.

Tartaric Acid 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 Tartaric Acid 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 Tartaric Acid 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 Sodium Oxybate’s Own FDA Label Lists

This is not an interaction — none of it involves Tartaric Acid. 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. Tartaric Acid’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Tartaric Acid side to compare — that is a limit of the record, not a statement that Tartaric Acid has no side effects.

Tartaric Acid in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

How to take them

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

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

See Every Supplement That Interacts With Sodium Oxybate

This page covers Tartaric Acid 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 Tartaric Acid

What is Tartaric Acid?

  • Food and drink flavoring (sour taste)
  • Antioxidant and preservative in foods
  • Effervescent and antacid products
  • Baking (as cream of tartar)
  • Cosmetic and skincare ingredient

Tartaric acid is a natural fruit acid found in grapes and used widely as a food additive for its tart flavor and as a component in baking and effervescent products. It is generally recognized as safe in the small amounts found in foods, but it is not a proven treatment for any health condition, and large amounts can upset the stomach. If you are considering supplements containing it, check with your pharmacist or doctor first.

Naturally found in grapes and other fruits; also made commercially · Powder, food additive, capsules, effervescent products, cream of tartar

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

Tartaric Acid: dosing

There is no established medicinal dose for tartaric acid, because it is not a proven treatment for any condition. Most people get it naturally as a small ingredient in foods, baked goods, and beverages.If you use a product that contains tartaric acid — such as an effervescent powder or a supplement — follow the directions on the label and do not exceed the recommended amount.

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

At least one FDA label for a product containing Sodium Oxybate says to take it with food. If you take Tartaric Acid on an empty stomach out of habit, keep them separate and take Sodium Oxybate with a meal where the label says to.
