There is no direct correlation between the new crown vaccination and nimesulide taking, when there is no contraindication to vaccination or other serious diseases can be vaccinated. Nimesulide dispersible tablets are non-steroidal anti-inflammatory drugs with anti-inflammatory, analgesic and antipyretic effects, and they are suitable for the treatment of chronic arthritis (such as osteoarthritis, etc.) pain, post-surgical and acute post-traumatic pain, and symptoms of primary dysmenorrhea. People who should not be vaccinated with XKV include those who are allergic to vaccine components, those with uncontrolled epilepsy and other serious neurological disorders, those who are suffering from fever, those suffering from acute illnesses, acute exacerbations of chronic illnesses, patients with uncontrolled serious chronic illnesses, those suffering from thrombocytopenia or hemorrhagic disorders, and women during pregnancy. The main groups of people who should suspend vaccination include: patients with unstable tuberculosis, chronic obstructive pulmonary disease, chronic bronchitis, heart disease, coronary heart disease, coronary artery atherosclerosis and other diseases, patients with malignant tumors before and after surgery, the presence of headache, dizziness, nausea, vomiting, chest tightness, stomach upset and so on. Therefore, the possibility of receiving New Crown Vaccine does not depend on whether or not one has taken Nimesulide Dispersible Tablets, but rather on the presence of the various diseases or symptoms mentioned above that are not suitable for vaccination. When patients are unsure, they can consult their doctor for help.
