Drug & supplement interaction

Jackfruit + Trimethoprim

Trimethoprim brand names: Proloprim, Trimpex.

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 Jackfruit and Trimethoprim 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.

Jackfruit and Trimethoprim

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 Trimethoprim and Jackfruit 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.

Jackfruit safety at a glance

Jackfruit overall Generally safe The ripe fruit is widely eaten and generally safe as a food for most people.
Pregnancy Use caution The fruit as food is likely fine, but concentrated supplements lack safety data and should be avoided unless approved by your doctor.
Breastfeeding Use caution Eating the fruit is likely fine, but there is not enough safety data on medicinal jackfruit products 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 Trimethoprim

Interactions in our licensed database are recorded against drug classes, not just single drug names. Trimethoprim is filed under 4 classifications — including qt interval-prolonging drugs, antibiotic drugs, oral drugs. Jackfruit has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and cns depressants (moderate) — and none of Trimethoprim’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 Jackfruit and Trimethoprim 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.

  • A severe allergic reaction / An allergic reaction Worth acting on Additional detail

    Jackfruit

    “Orally, the fruit of jackfruit might cause serious allergic reactions, including anaphylaxis, in sensitive individuals. In one case report, a 34-year-old female developed anaphylaxis with symptoms of cough, dyspnea, facial swelling, and urticaria after eating 10 pieces of dried jackfruit. There is speculation that latex allergy might result in a cross-reactivity to jackfruit.”

    Trimethoprim

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

Reported for Jackfruit but not commonly for Trimethoprim: hives, swelling, shortness of breath and cough.

Effects for Trimethoprim come from the ADVERSE REACTIONS section of its FDA label; effects for Jackfruit come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 93,588 voluntary FDA FAERS reports for Trimethoprim 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.

From our pharmacist’s overview on the Trimethoprim page

“Most prescriptions for trimethoprim are short courses for bladder infections, which makes it easy to assume nothing swallowed alongside it matters much. Seven of the 59 supplement and herbal ingredients here rate major, though, and nearly all of them involve heart rhythm: grapefruit in large amounts, ephedra, and a few others can prolo…”

About Jackfruit

What is Jackfruit?

Jackfruit
  • General nutrition
  • Blood sugar support
  • Digestive health (fiber)
  • Antioxidant support
  • Wound care (traditional, latex/leaves)

Jackfruit is a large tropical fruit that is nutritious and safe to eat as a food, offering fiber, vitamin C, potassium, and antioxidants. While its leaves, seeds, and other parts are used in traditional medicine for things like blood sugar and digestion, strong human evidence for these supplement uses is limited. Talk to your pharmacist or doctor before using concentrated jackfruit products for a health condition.

Artocarpus heterophyllus · Moraceae · Fruit, seeds, leaves, bark, roots, and latex · Fresh or canned fruit, dried fruit, flour, seeds, capsules, powder, and leaf or bark extracts

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

Jackfruit: dosing

There is no established standard dose for jackfruit as a supplement. As a food, you can simply enjoy it as part of a balanced diet.For capsules, powders, or extracts, no proven medicinal dose has been set in research, so follow the directions on the product label.

About Trimethoprim

What Is Trimethoprim Used For?

Brand names: Proloprim, Trimpex

Trimethoprim tablets are used to treat initial episodes of uncomplicated urinary tract infections (UTIs). It works against specific bacteria — including E. coli, Proteus mirabilis, Klebsiella pneumoniae, Enterobacter species, and coagulase-negative Staphylococcus species (including S. saprophyticus).

It should only be used when there is a proven or strongly suspected bacterial infection. Your doctor may order a urine culture to confirm which bacteria are present and whether trimethoprim will work against them.

Most-Reported Side Effects for Trimethoprim

From FAERS, the FDA’s public side-effect reporting system (95,001 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Jackfruit and Trimethoprim Together: Common Questions

Is it safe to take Jackfruit with Trimethoprim?
We do not list a known interaction between Jackfruit and Trimethoprim. 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 Jackfruit and Trimethoprim 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.
How was the Jackfruit and Trimethoprim combination checked?
Interactions in our licensed database are recorded against drug classes. Trimethoprim is filed under 4 classifications, and Jackfruit has documented interactions with 3 drug classes — none of Trimethoprim'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 Jackfruit interact with any other medications?
Yes. Jackfruit has 437 documented drug interactions in our database — Trimethoprim 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 Trimethoprim interact with any supplements?
Yes. Trimethoprim has documented interactions with 59 supplements in our database — Jackfruit is not one of them. The Trimethoprim interaction page linked on this page lists every one, ranked by severity.
