The use of this drug is strictly forbidden in people who have their own liver dysfunction. This drug is also less suitable for patients with high blood pressure, patients older than 75 years old, patients who are taking oral anticoagulants, etc. There is a risk of adverse reactions such as bleeding when taking this drug.
