Uterine Rupture, Abortion, Premature Birth, and Birth Defects. Administration of misoprostol, a component of diclofenac sodium/misoprostol, to pregnant women can cause uterine rupture, abortion, premature birth, or birth defects.

Uterine rupture has occurred when misoprostol was administered in pregnant women to induce labor or an abortion.

Diclofenac sodium/misoprostol is contraindicated in pregnancy and not recommended in women of childbearing potential.

Patients must be advised of the abortifacient property and warned not to give the drug to others.

If diclofenac sodium/misoprostol is prescribed, verify the pregnancy status of females of reproductive potential prior to initiation of treatment and advise them to use effective contraception during treatment.Cardiovascular Thrombotic EventsNSAIDs 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.Gastrointestinal Bleeding, Ulceration, and PerforationNSAIDs 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.

The highest reported incidences of adverse events for this drug were gastrointestinal and included abdominal pain, diarrhea, dyspepsia, nausea, and flatulence.^[Ref]

Gastrointestinal

Diclofenac-misoprostol:

• Very common (10% or more): Abdominal pain (21%), diarrhea (19%), dyspepsia (14%), nausea (11%)
• Common (1% to 10%): Flatulence, gastritis, vomiting, eructation, constipation, peptic ulcer
• Uncommon (0.1% to 1%): Stomatitis
• Rare (less than 0.1%): Esophageal ulceration, esophagitis, gastroesophageal reflux, heartburn, hematemesis, melena, gall bladder disorder
• Frequency not reported: Pancreatitis

Diclofenac:

• Very common (10% or more): Abdominal pain (15%), diarrhea (11%), dyspepsia (11%), nausea (11%)
• Common (1% to 10%): Flatulence, nausea^[Ref]

NSAIDs including this drug, can cause serious gastrointestinal (GI) events which can occur at any time, with or without warning. For patients who develop a serious upper GI event, only about 20% were symptomatic. Upper GI ulcers, gross bleeding, or perforation occurred in approximately 1% of patients treated with NSAIDs for 3 to 6 months and 2% to 4% of patients treated for 1 year. Patients with a prior history of peptic ulcer disease and/or GI bleeding had a greater than 10-fold increased risk for developing a GI bleed than patients with neither of these risk factors.^[Ref]

Cardiovascular

• Uncommon (0.1% to 1%): Hypertension, chest pain, edema, palpitation, syncope
• Rare (less than 0.1%): Arrhythmia, atrial fibrillation, hypotension, myocardial infarction, premature ventricular contractions, tachycardia, vasculitis, phlebitis
• Frequency not reported: Cardiac failure, palpitations^[Ref]

Clinical trials of several cyclooxygenase (COX)-2 selective and nonselective NSAIDs of up to 3 years duration have shown an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. All NSAIDs appear to have a similar risk. There is no consistent evidence that concurrent use of aspirin mitigates this increased risk and may be associated with an increased risk of serious gastrointestinal events.^[Ref]

Hepatic

• Common (1% to 10%): Alanine aminotransferase increased, aspartate aminotransferase increased
• Rare (less than 0.1%): Hepatitis, jaundice, abnormal hepatic function
• Frequency not reported: Liver failure
• Postmarketing reports: Hepatitis fulminant, blood bilirubin increased^[Ref]

Elevations to greater than 3 x ULN of ALT occurred in about 1.6% (n=2184) of patients receiving diclofenac-misoprostol at some point during treatment. These increases were generally transient and returned to within normal range upon discontinuation of therapy. In an open-labeled trial among patients receiving NSAIDs, a higher incidence of transaminase elevations were observed in patients receiving diclofenac compared with other NSAIDs.^[Ref]

Hypersensitivity

• Rare (less than 0.1%): Allergic reactions
• Frequency not reported: Angioedema, laryngeal/pharyngeal edema, urticaria
• Postmarketing reports: Anaphylaxis^[Ref]

Dermatologic

• Uncommon (0.1% to 1%): Purpura, urticaria
• Rare (less than 0.1%): Angioedema, increased sweating, acne
• Postmarketing reports: Toxic epidermal necrolysis, Stevens-Johnson syndrome, dermatitis exfoliative, dermatitis bullous, Henoch Schonlein purpura, mucocutaneous rash, rash vesicular, photosensitivity reaction, alopecia^[Ref]

NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time in some patients. Unlike aspirin, the NSAID effect on platelet function is quantitatively less, of shorter duration, and reversible.^[Ref]

Metabolic

• Rare (less than 0.1%): Anorexia, appetite changes, dehydration, hyperglycemia, hypoglycemia, hyponatremia, weight changes, gout, hypercholesterolemia, porphyria^[Ref]
