Cautions & Contraindications
Contraindications
Diclofenac Potassium tablets should not be used in patients who are hypersensitive to Diclofenac. Patients who have had asthma, urticaria, or an allergic-type reaction after taking aspirin or other NSAIDs should also avoid this medicine, since severe and occasionally fatal anaphylactic-like reactions to NSAIDs have occurred in such patients. Diclofenac must not be used for perioperative pain during coronary artery bypass graft (CABG) surgery.
