Contraindications - Celecoxib is contraindicated in patients with known hypersensitivity to Celecoxib. It should not be given to patients who have demonstrated allergic type reactions to Sulphonamides (Celecoxib contains a sulphonamide side chain). Celecoxib should not be given to patients who have demonstrated asthma, urticaria or allergic type reactions after taking Aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic like reactions to NSAIDs have been reported in such patients.
Others - Pregnancy & Lactation Celecoxib should be used during pregnancy only if the potential benefit justifies the potential risk to fetus. But in late pregnancy Celecoxib should be avoided because it may cause premature closure of ductus arteriosus. It is not known whether Celecoxib is excreted in human milk. Because many drugs are excreted in human milk and because of potential for serious adverse reactions in nursing infants from Celecoxib, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
