Precautions for taking celecoxib
Celecoxib, as a selective COX-2 inhibitor, requires special attention to cardiovascular, gastrointestinal, and allergic risks when used. The following provides a detailed explanation of medication precautions from six aspects, including dose management, contraindications, and adverse reaction monitoring, to ensure safe and effective treatment.
1. Dosage and Administration Management
(1) Conventional dosage: 200mg once daily or 100mg twice daily is recommended for osteoarthritis, and 200mg twice daily is recommended for rheumatoid arthritis.
(2) Maximum dose: not exceeding 400mg per day, reduced dosage is required for patients with liver dysfunction.
(3) Omission treatment: If it is more than 12 hours before the next dose, it can be taken again. If it is less than 12 hours, it will be skipped.
2. Absolute contraindications
(1) Sulfonamide allergy: Prohibited for individuals allergic to sulfonamide drugs.
(2) Cardiovascular disease: It is contraindicated for patients with recent myocardial infarction or coronary artery bypass surgery.
(3) Late pregnancy: may lead to premature closure of the fetal ductus arteriosus.
3. Adverse reaction monitoring
(1) Cardiovascular system: Regularly monitor blood pressure during medication and be alert to chest pain symptoms.
(2) Gastrointestinal bleeding: observe black stool or vomiting blood. For long-term medication, it is recommended to protect the gastric mucosa.
(3) Liver function: Monitor ALT before and during treatment, and discontinue medication if it increases threefold.
4. Medication for special populations
(1) Renal insufficiency: creatinine clearance rate<30ml/min is contraindicated.
(2) Elderly patients: Reduce the initial dose by 25% and closely monitor renal function.
(3) Breastfeeding period: Medication can be secreted into breast milk. It is recommended to discontinue medication or breastfeeding.
5. Drug interactions
(1) Anticoagulants: increase the risk of warfarin bleeding and require frequent monitoring of INR.
(2) Diuretics: Weakening the antihypertensive effect requires adjusting the dosage of diuretics.
(3) Fluconazole: CYP2C9 inhibitors can double the blood concentration of celecoxib.
6. Long term medication management
(1) Course control: The efficacy of continuous medication for osteoarthritis should be evaluated within 3 months.
(2) Cardiovascular assessment: Cardiovascular risk assessment is required before long-term medication.
(3) Gastric mucosal protection: High risk patients are recommended to use proton pump inhibitors in combination.
