Polivir, or clopidogrel bisulfate tablets, before doing gastroenteroscopy is generally recommended that patients need to stop using such anticoagulant and antiplatelet drugs to avoid the occurrence of bleeding after the operation or bleeding that is difficult to stop. Therefore, taking clopidogrel is generally not recommended for gastroenteroscopy.
Since the drug can reduce the coagulation of blood, it can increase the risk of inducing hemorrhage when doing operations such as gastroenteroscopy biopsy, which can be life-threatening in severe cases. Because of the increased risk of bleeding with medication, endoscopy operators may advise patients to discontinue relevant anticoagulant and antiplatelet drugs well in advance of the examination.
Generally, the operator is advised to stop taking clopidogrel in advance before the gastroenteroscopy. However, clopidogrel belongs to the antiplatelet aggregation drugs, mainly used in patients with recent myocardial infarction, ischemic stroke, or patients with peripheral arterial disease and acute coronary syndrome. There is an increased risk of thrombosis if the drug in question is discontinued. Therefore a comprehensive assessment is needed to decide.
In general, if the drug is discontinued after professional evaluation by a physician, the drug should be resumed as soon as possible after the completion of the gastrointestinal examination. The specific discontinuation plan should be consulted with a specialized physician.
Prompt medical attention is recommended for standardized diagnosis and treatment.
