What is this page for?

First and foremost: how Strawberry interacts with medications. The heart of this page is the interaction list — every drug Strawberry is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Strawberry 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

Strawberry Drug Interactions: The Bottom Line

From the HelloPharmacist Editorial Team · Updated July 2026

Based on the available evidence, the overall risk of a clinically significant Strawberry drug interaction appears low for most people. None of the listed interactions are rated major, and every one rests on lab or animal research rather than effects confirmed in people.

Interactions deserving the most attention

The combination most worth knowing about involves blood thinners such as warfarin, aspirin, and clopidogrel, because lab studies suggest strawberry's plant compounds might slow blood clotting, which could theoretically add to bleeding risk. Lab research also hints that strawberry could affect a transporter the body uses to move certain medications out of cells, which might raise levels of some drugs, including certain chemotherapy medications. Neither of these effects has been shown to happen in people eating strawberries.

What the rest of the list means

Although the number of listed medications is large, this comes almost entirely from those two theoretical mechanisms applied across many drugs, not from reported problems in people. Most of these combinations have never been shown to cause a meaningful change in how a medication works, so the length of the list says more about how many drugs share a common pathway than about real-world danger.

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.

Every type of medication (drug category) Strawberry is known to interact with. Open any category for the detail — or search your exact drug in the checker above.

All 2 drug categories Strawberry interacts with

Anticoagulant/antiplatelet DrugsP-glycoprotein Substrates

Anticoagulant/Antiplatelet Drugs

In vitro and animal research suggests that strawberry extract can inhibit platelet aggregation due to its phenolic content. Theoretically, strawberry might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D

P-Glycoprotein Substrates

In vitro research suggests that strawberry extract can inhibit p-glycoprotein efflux. Theoretically, strawberry might inhibit p-glycoprotein mediated drug efflux and potentially increase levels of drugs that are substrates of p-glycoprotein. Until more is known, strawberry should be used cautiously in people taking p-glycoprotein substrates.
Drugs that might be affected include some chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), protease inhibitors (amprenavir, indinavir, nelfinavir, saquinavir), H2 antagonists (cimetidine, ranitidine), some calcium channel blockers (diltiazem, verapamil), corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.

The bottom line

Strawberry is a popular, nutrient-rich fruit that supplies vitamin C, fiber, and antioxidant plant compounds. Eating strawberries as part of a balanced diet is healthy for most people, but concentrated supplement forms have only limited research behind specific health claims. If you have allergies or take it as a supplement, check with your pharmacist or doctor.

Scientific name: Fragaria × ananassa
Family: Rosaceae
Part used: Fruit (berries); leaves are also used in some traditional preparations
Common forms: Fresh or frozen fruit, juice, powder, extracts, capsules, and leaf tea

People commonly use it for

General antioxidant support
Heart and blood vessel health
Blood sugar support
Skin and oral health

Overview

Strawberry is the soft, red fruit of the Fragaria plant, a member of the rose family. The common garden strawberry grown around the world is a hybrid called Fragaria × ananassa. The plants are low-growing and are cultivated widely in temperate regions of North America, Europe, and Asia.

Most people enjoy strawberries simply as food. They are also sold as juices, dried powders, and concentrated extracts in capsules. The leaves are sometimes brewed into a mild tea in traditional herbal practice. Strawberries are valued because they are low in calories yet rich in vitamin C, fiber, and natural plant pigments called anthocyanins.

How it works

Strawberries contain several compounds that may explain their proposed benefits. Vitamin C supports the immune system and skin, while fiber aids digestion and may help with cholesterol and blood sugar. The red color comes from anthocyanins, a type of antioxidant. Strawberries also contain other polyphenols such as ellagic acid.

In laboratory and animal studies, these antioxidant compounds appear to reduce oxidative stress and inflammation. However, what happens in a test tube does not always translate to real benefits in people, and the amounts used in research may be higher than what a normal serving provides.
