There is no such medication as celecoxib tablets in the clinic, but celecoxib capsules. Celecoxib capsule is a non-steroidal anti-inflammatory drug that inhibits cyclooxygenase-2 and is used to relieve the signs and symptoms of rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis in adults, as well as for acute pain in adult patients. It can have side effects such as indigestion, headache, upper respiratory tract infections, and diarrhea. The drug increases the cardiovascular risk and grows with the elevated dose of the drug and the duration of its use, so it should be taken for as little time as possible and in as small a dose as possible. In addition, the drug interacts with warfarin, aspirin, propranolol and other drugs, so you should consult a specialized doctor or pharmacist when using it. It is contraindicated in the following cases: allergy to the drug; allergic reactions such as asthma after taking aspirin or other cyclooxygenase-2 inhibitors; allergy to sulfa; active gastrointestinal bleeding or ulcers; coronary artery bypass grafting surgery; patients with severe heart failure; and pregnant women ≥ 30 weeks of gestation. If you need to use the drug patients, please under the guidance of the doctor strictly follow the instructions of the doctor to take medication, do not self-medication.
