Drug & supplement interaction

Olive + Ramelteon

Ramelteon brand name: Rozerem.

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 Olive and Ramelteon 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.

Olive and Ramelteon

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 Ramelteon and Olive 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Olive at all — not against Ramelteon, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

Olive safety at a glance

Olive overall Use caution Olive as food and oil is very safe, but concentrated supplements are less studied.

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

No Interaction Found — But Data Suggests Olive and Ramelteon 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.

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

Reported for Olive but not commonly for Ramelteon: stomach upset and acne.

Effects for Ramelteon come from the ADVERSE REACTIONS section of its FDA label; effects for Olive come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,279 voluntary FDA FAERS reports for Ramelteon 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 Ramelteon page

“Ramelteon (Rozerem) is a prescription sleep aid, and its 228 interacting supplements call for real care, starting with the nine rated major. The frustrating part is that the things sleepless people typically reach for, kava, CBD, a glass of wine before bed, sit at the heart of the problem.”

About Olive

What is Olive?

Olive
  • Heart health
  • High blood pressure
  • High cholesterol
  • Antioxidant support
  • Antimicrobial
  • General wellness

Olive comes from the same tree that gives us olives and olive oil, and its leaf and fruit contain antioxidant compounds like oleuropein and hydroxytyrosol. Olive oil as part of a Mediterranean diet is well-studied for heart health, but supplements made from olive leaf or fruit extract have less solid evidence. Talk to your pharmacist or doctor before starting any supplement, especially if you have health conditions or take medications.

Olea europaea · Oleaceae · Leaves and fruit (including olive fruit pulp and olive oil) · Capsules, tablets, liquid extracts, teas, olive leaf extract, olive oil

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

Olive: dosing

There is no official standard dose for olive leaf or olive fruit supplements. Products vary widely in their strength and in how much oleuropein or hydroxytyrosol they contain.The best advice is to follow the directions on the product label and not exceed the recommended amount.

Taking Olive and Ramelteon Together: Common Questions

Do Olive and Ramelteon 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.
