Banana + Tasimelteon
Tasimelteon brand names: Hetlioz, Hetlioz Lq.
We found no known interaction between Banana 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.
Banana 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 Banana 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.
Banana safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
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. Banana has documented interactions with 1 drug class — the most serious being levodopa (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.
Banana Does Interact With Other Medications
Banana has 5 moderate known drug interactions in our database — Tasimelteon isn’t one of them. If you take anything else, check it against the full list below.

Some Tasimelteon Products Have a Food Rule — Banana Should Not Break It
At least one FDA label for a product containing Tasimelteon says to take it on an empty stomach. Most supplements — Banana 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 Banana 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. Nine of the 218 ingredients on file rate major, mostly in two directions: sedatives like kava stack drowsiness onto a…”

About Banana
What is Banana?
- Source of potassium and energy
- Digestive health and diarrhea
- Blood pressure support
- Heartburn and stomach ulcers (traditional)
- Weight management
Bananas are a nutritious, widely eaten fruit that provide potassium, fiber, vitamin B6, and quick energy, and they are part of a healthy diet. While some traditional uses (like easing diarrhea or supporting blood pressure) have plausible support, most specific health claims are not strongly proven. For most people bananas are a safe food, but those with kidney problems or a latex-fruit allergy should be cautious.
Musa acuminata · Musaceae · Fruit (most common); peel, flower, and leaves are also used in some traditions · Fresh fruit, dried banana, banana powder, green (unripe) banana flour, smoothies
An interaction check asks whether these two react with each other — it does not ask whether Banana is a good idea for someone in your situation. Here is what our Banana record says about it on its own.
Banana: dosing
There is no official medicinal dose for bananas. As a food, one to a few bananas per day fits easily into a healthy diet for most people.For banana supplements, powders, or green banana flour, a standardized dose has not been established.
