What other issues should I be aware of while taking anticoagulants? While taking anticoagulants, patients are advised to pay special attention to the following: (1) Surgery: If surgery is required for other medical conditions, be sure to tell your doctor that you are taking anticoagulants. The doctor will decide when and how to operate, and the appropriate alternative treatment to choose before and after surgery. (2) Pregnancy: Warfarin has an effect on fetal development and the blood is hypercoagulable during pregnancy, making it easy for blood clots to form on the valves. It is recommended that you consult a specialist in detail before planning pregnancy. (3) Pay attention to safety and avoid trauma. If there is a wound or bleeding from the injection, compress the bleeding site for a long time. (4) If the manufacturer of the warfarin you buy changes, please pay attention to recognize the dosage of each tablet (there are 2.5 mg (domestic), 3 mg (imported) multiple dosage forms). Different manufacturers and different dosage forms cannot simply use the number of milligrams for equivalent calculation, and you need to check the INR diligently after the change in order to grasp the amount of medication used as soon as possible. (5) Avoid drinking alcohol as much as possible. You can drink tea. The effect of smoking on warfarin is uncertain. Do not take herbal medicine at will. (6), need patients must remember is the following three conditions must be diligent anticoagulation check! A, medication habits change: such as new drugs or the original drug dose adjustment (intravenous or oral drugs are to be noted). B, a major change in dietary habits: for example, the patient moved from inland areas to coastal areas for a long time, the diet structure from beef and lamb-based to seafood-based. C, anticoagulation results suddenly appear large changes in the original stable situation: for example, the original anticoagulation has been stable, and suddenly once the anticoagulation results increased, INR more than 3.0, in order to prevent wrong results due to test errors, it is recommended to immediately stop the same day, and recheck the anticoagulation again.
