Drug & supplement interaction

Lychee + Olsalazine Sodium

Olsalazine Sodium brand name: Dipentum.

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 Olsalazine Sodium 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.

Lychee and Olsalazine Sodium

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 Olsalazine Sodium 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 Olsalazine Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Olsalazine Sodium is filed under a single classification — oral drugs. Lychee has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and immunosuppressants (minor) — and none of Olsalazine Sodium’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 Olsalazine Sodium 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. 2 of them are worth acting on rather than waiting out — marked below.

  • Shortness of breath / An allergic reaction Worth acting on Additional detail

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

    Topically, contact with lychee fruit can cause allergic contact dermatitis.”

From our pharmacist’s overview on the Olsalazine Sodium page

“Olsalazine sodium (Dipentum) treats ulcerative colitis, and it only works if enough of the drug travels intact to the colon, so anything that binds it or interferes with its passage through the gut deserves real attention. All 17 supplement interactions on file involve absorption, and one carries a major rating: activated charcoal, whi…”

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 Olsalazine Sodium Together: Common Questions

Is it safe to take Lychee with Olsalazine Sodium?
We do not list a known interaction between Lychee and Olsalazine Sodium. 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 Olsalazine Sodium 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.
How was the Lychee and Olsalazine Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Olsalazine Sodium is filed under 1 classification, and Lychee has documented interactions with 2 drug classes — none of Olsalazine Sodium'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 — Olsalazine Sodium 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 Olsalazine Sodium interact with any supplements?
Yes. Olsalazine Sodium has documented interactions with 17 supplements in our database — Lychee is not one of them. The Olsalazine Sodium interaction page linked on this page lists every one, ranked by severity.
