Bay Aspirin generally refers to aspirin enteric-coated tablets produced by Bayer, clopidogrel’s full name is clopidogrel bisulfate tablets, the two can usually replace each other, but if you need to change the medication, please change under the guidance of a doctor. Clopidogrel bisulfate tablets and aspirin enteric-coated tablets have roughly the same effect, which can inhibit the function of platelets in the blood to prevent aggregation and growth of blood clots, and both of them have similar effects and strength, so they can usually be replaced by each other. However, they should not be replaced arbitrarily, and need to be fully evaluated by a doctor and then interchanged under the doctor’s guidance. It should be noted that aspirin enteric-coated tablets are contraindicated in people who are allergic to aspirin enteric-coated tablets, people with active ulcer disease or other causes of gastrointestinal bleeding, hemophilia or thrombocytopenia. Gastrointestinal adverse reactions such as nausea, vomiting, epigastric discomfort or pain are more common with aspirin enteric-coated tablets. Clopidogrel bisulfate is contraindicated in persons who are hypersensitive to the active substance of clopidogrel bisulfate tablets or to any of the components of the product, in persons with severe hepatic impairment, or in persons with active pathologic bleeding. Severe skin hemorrhage (purpura), musculoskeletal hemorrhage (joint effusion, hematoma), eye hemorrhage (conjunctival, intraocular, retinal hemorrhage), and nosebleeds may occur with clopidogrel bisulfate. If you have a need for medication or substitution, use it under your doctor’s supervision.
