Diclofenac sodium/misoprostol should not be administered during pregnancy as abortion, premature birth, or birth defects can occur. Avoid use in women of childbearing potential unless the patient requires NSAID therapy and is at high risk of developing complications from gastric or duodenal ulcers and meets the following criteria: has a negative serum pregnancy test within 2 weeks of treatment initiation, uses effective contraception, receives oral and written warnings of the hazards of misoprostol, and initiates therapy only on the second or third day of her next normal menstrual period. NSAIDs cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use. Diclofenac sodium/misoprostol is contraindicated in the setting of CABG surgery. NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events .
