Ivy Gourd + Tasimelteon

Tasimelteon brand names: Hetlioz, Hetlioz Lq.

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 Ivy Gourd and Tasimelteon 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 Tasimelteon 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.

Ivy Gourd and Tasimelteon

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 Tasimelteon and Ivy Gourd 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.

Ivy Gourd safety at a glance

Ivy Gourd overall Use caution Generally considered safe as a food, but supplement doses are less studied and may affect blood sugar.
Pregnancy Avoid There is not enough safety information, so medicinal amounts are best avoided during pregnancy.
Breastfeeding Avoid Safety has not been established, so it is best to avoid medicinal 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 Tasimelteon

Interactions in our licensed database are recorded against drug classes, not just single drug names. Tasimelteon is filed under 5 classifications — including cytochrome p450 1a2 (cyp1a2) substrates, cytochrome p450 1a2 (cyp1a2) substrates, cns depressants. Ivy Gourd has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Tasimelteon’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.

No Interaction Found — But Data Suggests Ivy Gourd and Tasimelteon May Share a Side Effect

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.

    Tasimelteon

    Listed in the ADVERSE REACTIONS section of the FDA label for Tasimelteon, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Ivy Gourd but not commonly for Tasimelteon: drowsiness and nausea.

Effects for Tasimelteon come from the ADVERSE REACTIONS section of its FDA label; effects for Ivy Gourd come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 5,765 voluntary FDA FAERS reports for Tasimelteon 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.

How to take them

Some Tasimelteon Products Have a Food Rule — Ivy Gourd Should Not Break It

At least one FDA label for a product containing Tasimelteon says to take it on an empty stomach. Most supplements — Ivy Gourd included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Tasimelteon on its own and move Ivy Gourd to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Tasimelteon 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.

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.

From our pharmacist’s overview on the Tasimelteon page

“Tasimelteon (Hetlioz) resets the body clock in people with non-24-hour sleep-wake disorder, and the sleep aids they often reach for, melatonin and kava among them, sit on an interaction list that deserves real respect.

About Ivy Gourd

What is Ivy Gourd?

  • Blood sugar support
  • Digestive complaints
  • Skin conditions
  • General wellness and nutrition

Ivy gourd is a tropical vine widely eaten as a vegetable and used in traditional medicine, most often for blood sugar support. Early human research hints it may modestly lower blood sugar, but the evidence is limited and not strong enough to replace standard diabetes care. If you have diabetes or take medicine, talk to your pharmacist or doctor before using ivy gourd supplements.

Coccinia grandis · Cucurbitaceae · Fruit, leaves, stems, and roots · Fresh vegetable, dried powder, capsules, leaf extracts, teas

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

Ivy Gourd: dosing

There is no official or well-established standard dose for ivy gourd supplements. Studies have used different forms and amounts, so it is hard to recommend a specific dose.If you choose to use an ivy gourd product, follow the directions on the product label and do not exceed the recommended amount.

Taking Ivy Gourd and Tasimelteon Together: Common Questions

Is it safe to take Ivy Gourd with Tasimelteon?
We do not list a known interaction between Ivy Gourd and Tasimelteon. 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 Ivy Gourd and Tasimelteon have any of the same side effects?
Yes — our sources link each of them separately to one 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 Ivy Gourd and Tasimelteon at the same time of day?
At least one FDA label for a product containing Tasimelteon says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Tasimelteon on its own and move Ivy Gourd to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Ivy Gourd and Tasimelteon combination checked?
Interactions in our licensed database are recorded against drug classes. Tasimelteon is filed under 5 classifications, and Ivy Gourd has documented interactions with 1 drug class — none of Tasimelteon'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 Ivy Gourd interact with any other medications?
Yes. Ivy Gourd has 86 documented drug interactions in our database — Tasimelteon 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 Tasimelteon interact with any supplements?
Yes. Tasimelteon has documented interactions with 218 supplements in our database — Ivy Gourd is not one of them. The Tasimelteon interaction page linked on this page lists every one, ranked by severity.
