The most common adverse effects are headache, abdominal pain, dyspepsia, diarrhea, nausea, flatulence, and insomnia. Other side effects include fainting, kidney failure, heart failure, aggravation of hypertension, chest pain, ringing in the ears, deafness, stomach and intestinal ulcers, bleeding, blurred vision, anxiety, photosensitivity, weight gain, water retention, flu-like symptoms, drowsiness and weakness. Celecoxib, like other NSAIDs may cause serious stomach and intestinal ulcers that may occur at any time during treatment. Celecoxib does not interfere with the function of the blood platelets and, as a result, does not reduce clotting and lead to increased bleeding time like other NSAIDs. Allergic reactions can occur with celecoxib. Individuals who have developed allergic reactions (rash, itching, difficulty breathing) from sulfonamides [for example, sulfamethoxazole and trimethoprim (Bactrim)], aspirin or other NSAIDs may experience an allergic reaction to celecoxib and should not take celecoxib. NSAIDs may increase the risk of heart attacks, stroke, and related conditions, which can be fatal. This risk may increase with duration of use and in patients who have underlying risk factors for heart and blood vessel conditions. NSAIDs should not be used for the treatment of pain resulting from coronary artery bypass graft (CABG) surgery. NSAIDs cause an increased risk of serious, even fatal, stomach and intestinal adverse reactions such as bleeding, ulcers, and perforation of the stomach or intestines. These events can occur at any time during treatment and without warning symptoms. Elderly patients are at greater risk for these types of reactions.
