Bergamot Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Bergamot interacts with medications. The heart of this page is the interaction list — every drug Bergamot is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Bergamot is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Add one medicationBergamot Drug Interactions: The Bottom Line
From the HelloPharmacist Editorial Team · Updated July 2026Based on the available evidence, the overall risk of a clinically significant Bergamot drug interaction appears low for most people. None of the listed interactions are rated major, and the concerns rest mainly on animal research or theoretical effects rather than proven problems in people.
The best-documented concern involves photosensitizing drugs, medicines that make skin more sensitive to sunlight. Bergamot contains a compound called bergapten that can have the same effect, so applying bergamot essential oil to the skin while taking these medicines may raise the chance of sun-related skin reactions. There is also a theoretical concern with diabetes medications, since animal research suggests bergamot juice may lower blood sugar, which could add to the effect of these drugs. Anyone whose blood sugar is closely managed may want to keep this in mind.
A long list of interacting medications can look worrying, but it does not mean every combination is harmful. Most entries here come from just two broad medication groups, and the concerns are largely theoretical, drawn from animal studies or the known properties of bergamot's compounds. So far, these predicted effects have not been confirmed as meaningful problems in well-controlled human studies.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Bergamot contains bergapten, which has photosensitizing effects.
Bergamot: Uses, Safety & Side Effects
Bergamot is a Mediterranean citrus fruit, and its standardized extract is most often used to support cholesterol and heart health, with some early but promising research. The essential oil is widely used for fragrance and aromatherapy but should not be taken by mouth, and it can make skin more sensitive to sunlight. Talk with your pharmacist or doctor before using bergamot supplements, especially if you take medicine for cholesterol or blood sugar.

Overview
Bergamot (Citrus bergamia) is a citrus fruit grown mainly in the Calabria region of southern Italy, along the Mediterranean coast. It looks like a small, yellow-green orange and has a fragrant peel.
The fruit is best known for two very different products. Bergamot essential oil, pressed from the peel, gives Earl Grey tea its flavor and is used in perfumes, cosmetics, and aromatherapy. Bergamot extract, made from the fruit and juice and rich in plant compounds called flavonoids, is used in dietary supplements—often standardized to a set percentage of total flavonoids.
In traditional medicine, bergamot has been used for soothing, antiseptic, and mood-related purposes. Today, most supplement interest focuses on its possible effects on cholesterol and metabolic health.
How it works
Bergamot fruit is rich in flavonoids—natural plant compounds such as neoeriocitrin, neohesperidin, and a group sometimes called "brutieridin" and "melitidin." Some of these compounds have a chemical structure that researchers think may act in ways loosely similar to how statin medicines affect cholesterol production, though this is mostly based on laboratory work.
Bergamot flavonoids also act as antioxidants, which may help reduce inflammation and oxidative stress in cells. These mechanisms could help explain the possible effects on cholesterol and blood sugar.
The essential oil contains aromatic compounds like limonene and linalool, which are thought to influence mood when inhaled. It also contains bergapten (a furocoumarin) that makes skin more sensitive to sunlight. Many of these mechanisms are based on laboratory or animal research and are not fully proven in humans.

Safety & precautions
Bergamot extract taken by mouth appears generally well tolerated in short-term studies. However, long-term safety is not well established, and high-quality safety data are limited.
Important: Bergamot essential oil is meant for fragrance and topical or aromatherapy use—it should not be swallowed, as essential oils can be toxic if taken internally. On the skin, bergamot oil that still contains bergapten can cause phototoxicity: skin that has touched it can burn or develop dark patches when exposed to sunlight. Many cosmetic oils are "bergapten-free" to reduce this risk.
People with diabetes or those on cholesterol-lowering treatment should use bergamot supplements only with medical guidance, since it may affect blood sugar or cholesterol. Stop use and seek care if you have signs of an allergic reaction.
Pregnancy and breastfeeding: There is not enough reliable safety information for either situation. To be safe, avoid bergamot supplements and essential oil while pregnant or breastfeeding unless your doctor approves.
Side effects
Bergamot extract is usually well tolerated, but some people report mild side effects such as heartburn, stomach upset, or dizziness.
The essential oil applied to skin can cause irritation and, importantly, can lead to sunburn-like reactions or skin discoloration if the treated skin is exposed to sunlight. Some people may also have allergic reactions to citrus oils.
Serious problems are uncommon with normal use, but swallowing the essential oil can be dangerous. If you have severe symptoms, trouble breathing, or signs of an allergic reaction, seek medical care right away.

Muscle cramps Musculoskeletal
Orally, muscle cramps have been reported for a patient starting one week after switching from drinking 4 liters of black tea to drinking 4 liters of Earl Grey tea daily. The muscle cramps were attributed bergapten, a constituent of bergamot essential oil in Earl Grey tea. The patient's symptoms subsided after discontinuing Earl Grey tea intake and remained absent upon re-initiation of Earl Grey tea intake 1 liter daily.
Adverse-effects data: Natural Medicines, Therapeutic Research Center
Dosing
There is no official, well-established standard dose for bergamot. Supplements are often standardized to a percentage of total flavonoids, and the amount per capsule varies a lot between products.
The best approach is to follow the directions on the product label and not exceed the recommended amount. Because product strength and quality differ, choose brands that test for quality and clearly list the standardized flavonoid content.
Bergamot essential oil should not be taken by mouth. For any oral supplement use, check first with your pharmacist or doctor, especially if you take prescription medicines or have a health condition.
