Can You Take Clopidogrel with Garlic?

Clopidogrel is an antiplatelet medication that may have interactions with garlic, which is known to have blood-thinning properties. While the evidence is limited, there is a theoretical risk that garlic could enhance the effects of clopidogrel, potentially increasing the risk of bleeding. It is advisable to consult a healthcare provider before combining these substances.
