6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adverse reaction information for diclofenac sodium/misoprostol is derived from multinational controlled clinical trials in over 2,000 patients receiving diclofenac sodium/misoprostol 50 or diclofenac sodium/misoprostol 75, as well as from blinded, controlled trials of diclofenac sodium delayed-release tablets and misoprostol tablets
GI disorders had the highest reported incidence of adverse reactions for patients receiving diclofenac sodium/misoprostol. These events were generally minor, but led to discontinuation of therapy in 9% of patients on diclofenac sodium/misoprostol and 5% of patients on diclofenac sodium. For GI ulcer rates, [see Clinical Studies (14)].
|GI disorder||Diclofenac sodium/misoprostol||Diclofenac Sodium|
Diclofenac sodium/misoprostol can cause more abdominal pain, diarrhea, and other GI symptoms than diclofenac alone.
Diarrhea and abdominal pain developed early in the course of therapy, and were usually self-limited (resolved after 2 to 7 days). Rare instances of profound diarrhea leading to severe dehydration have been reported in patients receiving misoprostol. Patients with an underlying condition such as inflammatory bowel disease, or those in whom dehydration, were it to occur, would be dangerous, should be monitored carefully if diclofenac sodium/misoprostol is prescribed. The incidence of diarrhea can be minimized by administering diclofenac sodium/misoprostol with food and by avoiding coadministration with magnesium-containing antacids.
Gynecological disorders previously reported with misoprostol use have also been reported for women receiving diclofenac sodium/misoprostol (see below). Postmenopausal vaginal bleeding may be related to administration of diclofenac sodium/misoprostol. If it occurs, diagnostic workup should be undertaken to rule out gynecological pathology [see Boxed Warnings, Contraindications (4) and Warnings and Precautions (5)].
Overall, there were no significant differences in the safety profile of diclofenac sodium/misoprostol in over 500 patients 65 years of age or older compared with younger patients.

6.2 Postmarketing Experience
The following adverse reactions have been identified during post approval of diclofenac sodium/misoprostol, diclofenac or misoprostol. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliable estimate their frequency or establish a causal relationship to drug exposure.
