Interaction Details
Diclofenac Potassium is classified as belonging to the following category: Anticoagulant/Antiplatelet Drugs
In vitro research shows that bear's garlic and some of its constituents can inhibit platelet aggregation. Theoretically, bear's garlic 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.

Bear's Garlic Overview
Bear's garlic, also known as wild garlic or Allium ursinum, is a perennial plant native to Europe and parts of Asia. The herb and bulb of bear's garlic are commonly used in culinary applications, prized for their mild garlic flavor. Bear's garlic contains various beneficial compounds, including glucopyranoside, kaempferol, and flavonoids, although levels of alliin, a compound found in garlic, are lower in bear's garlic. It's important to note that many of these compounds are degraded if the plant is dried.
Research suggests that bear's garlic exhibits cardioprotective effects, with in vitro studies showing promising results. It moderately inhibits the angiotensin-converting enzyme (ACE), which could contribute to its purported cardioprotective and blood pressure-lowering effects. Additionally, bear's garlic leaf extract has been found to inhibit platelet aggregation in vitro, mainly through the inhibition of the ADP pathway. Specific non-sulphur constituents, such as 1,2-di-O-alpha-linolenoyl-3-O-beta-D-galactopyranosyl-sn-glycerol and beta-sitosterol-3-O-beta-D-glucoside, appear to be the most active antiplatelet constituents, along with some flavonoids.
Diclofenac Potassium Overview
-
Diclofenac capsules (Zipsor, Zorvolex) and tablets (Cataflam) are used to relieve mild to moderate pain. Diclofenac extended-release tablets (Voltaren XR), tablets (Cataflam), and delayed-release tablets (available generically) are used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints), and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints). Diclofenac extended-release tablets and delayed-release tablets are also used to treat ankylosing spondylitis (arthritis that mainly affects the spine). Diclofenac tablets (Cataflam) are also used to treat painful menstrual periods. Diclofenac solution (Cambia) is used to treat migraine headaches in adults, but cannot be used to prevent migraines or to treat other types of headaches. Diclofenac is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation.
