Bleeding gums caused by taking rivaroxaban may be a side effect of the drug, or it may be caused by other reasons, such as dental calculus. Rivaroxaban is an antithrombotic drug, which is an anticoagulant drug, used to prevent thromboembolic diseases, and may cause some effects on the coagulation function after using the drug. However, most of them are caused by improper use of medication, for example, too much medication may lead to bleeding gums, which may also be manifested as bleeding in other parts of the body. However, bleeding gums are not necessarily caused by taking rivaroxaban, but may be due to other factors, such as dental calculus, which is also likely to cause irritation to the gums, thus causing teeth to bleed. It is contraindicated in people who are allergic to the drug; patients with clinically active bleeding, pregnant and lactating women, and patients with hepatic disease accompanied by coagulation abnormalities and clinically relevant bleeding risk. If adverse reactions, such as bleeding, occur after taking the drug, stop taking the drug immediately and seek medical advice. Rivaroxaban should not be used on its own, and the medication must be taken in doses and in strict accordance with the doctor’s instructions.
