Interactions with pharmaceuticals

Medications moved by pumps in cells (P-glycoprotein Substrates)

Interaction Rating=Moderate Be cautious with this combination.

Some medications are moved by pumps into cells. Strawberry might make these pumps less active and increase how much of some medications get absorbed by the body. This might increase the side effects of some medications.

Some medications that are moved by these pumps include etoposide, paclitaxel, vinblastine, vincristine, vindesine, ketoconazole, itraconazole, amprenavir, indinavir, nelfinavir, saquinavir, cimetidine, ranitidine, diltiazem, verapamil, corticosteroids, erythromycin, cisapride (Propulsid), fexofenadine (Allegra), cyclosporine, loperamide (Imodium), quinidine, and others.

Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)

Interaction Rating=Moderate Be cautious with this combination.

Using larger amounts of strawberry might slow blood clotting. Taking strawberry along with medications that also slow clotting might increase the chances of bruising and bleeding in some people.

Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.

Interactions with herbs & supplements

Herbs and supplements that might slow blood clotting: Using larger amounts of strawberry might slow blood clotting. Using it with other herbs or supplements that have this same effect might increase the risk of bleeding and bruising in some people. Some of these herbs include angelica, clove, danshen, garlic, ginger, ginkgo, Panax ginseng, and others.

Interactions with foods

There are no known interactions with foods.

Action

Strawberry contains chemicals that are antioxidants and might keep cancer cells from multiplying. Other chemicals in strawberry might slow down the speed at which the nervous system ages. That's why some researchers are interested in studying whether strawberry might help prevent or treat Alzheimer's disease or other diseases that involve progressive loss of nerve function.
