Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate brand name: Xywav.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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.

Interaction report

Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate and Lychee 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.

Lychee safety at a glance

Lychee overall Use caution The fruit is generally safe as food, but concentrated extracts are not well studied and unripe fruit carries specific risks.
Pregnancy Use caution Eating lychee fruit in normal food amounts is likely fine, but concentrated extracts have not been studied and should be avoided.
Breastfeeding Use caution Lychee as a food is likely fine, but there is not enough safety data on extracts during breastfeeding.

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

How we checked

Why No Interaction Is Listed for Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate is filed under 2 classifications — seizure threshold lowering drugs, oral drugs. Lychee has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and immunosuppressants (minor) — and none of Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 to actually watch for

No Interaction Found — But Data Suggests Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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. One of them is worth acting on rather than waiting out — marked below.

  • An allergic reaction Worth acting on Additional detail

    Lychee

    “Orally, lychee can cause allergic reactions such as urticaria, dermatitis, tongue and lip swelling, shortness of breath, and anaphylaxis.

How to take them

Some Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate Products Have a Food Rule — Lychee Should Not Break It

At least one FDA label for a product containing Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate says to take it with food. If you take Lychee on an empty stomach out of habit, keep them separate — and take Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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.

Important Administration Information • Administer XYWAV at least 2 hours after eating ( 2.4 ).

From the Dosage and Administration section of the FDA label we read for Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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.

About Lychee

What is Lychee?

  • General nutrition and antioxidant support
  • Digestive complaints (traditional use)
  • Cough and sore throat (traditional use)
  • Blood sugar support (preliminary)
  • Weight and metabolic support (preliminary)

Lychee is a sweet tropical fruit that is nutritious and a source of vitamin C and antioxidant plant compounds. While the fruit is a healthy food for most people, supplement-strength extracts have only limited research behind specific health claims, and eating large amounts of unripe lychee on an empty stomach has been linked to dangerous low blood sugar in undernourished children. Talk to your pharmacist or doctor before using lychee extracts for any health condition.

Litchi chinensis · Sapindaceae · Fruit (pulp), seed, and peel; sometimes flowers and leaves · Fresh or dried fruit, juice, extract capsules, seed powder, teas

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

Lychee: dosing

There is no established standard dose for lychee supplements or extracts. The fruit itself can be eaten as a normal part of the diet in moderation.If you use a lychee extract or capsule product, follow the directions on the product label, and do not exceed the recommended amount.

Taking Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate Together: Common Questions

Is it safe to take Lychee with Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate?
We do not list a known interaction between Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate have any of the same side effects?
Yes — our sources link each of them separately to 2 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 Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate at the same time of day?
At least one FDA label for a product containing Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate says to take it with food. If you take Lychee on an empty stomach out of habit, keep them separate and take Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Lychee and Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate combination checked?
Interactions in our licensed database are recorded against drug classes. Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate is filed under 2 classifications, and Lychee has documented interactions with 2 drug classes — none of Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Lychee interact with any other medications?
Yes. Lychee has 207 documented drug interactions in our database — Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, 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 Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate interact with any supplements?
Yes. Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate has documented interactions with 23 supplements in our database — Lychee is not one of them. The Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate interaction page linked on this page lists every one, ranked by severity.
