ALERT U.S. Boxed Warning

Pregnancy:

This product contains diclofenac and misoprostol. The administration of misoprostol to women who are pregnant can cause abortion, premature birth, or birth defects.

Uterine rupture has been reported when misoprostol was administered to pregnant women to induce labor or to induce abortion beyond the eighth week of pregnancy. Diclofenac/misoprostol should not be taken by pregnant women.

Advise patients of the abortifacient property and warn them not to give the drug to others. Do not use in women of childbearing potential unless the patient requires nonsteroidal anti-inflammatory drug (NSAID) therapy and is at high risk of developing gastric or duodenal ulceration or of developing complications from gastric or duodenal ulcers associated with the use of the NSAID. In such patients, this drug may be prescribed if the patient:

- had a negative serum pregnancy test within 2 weeks prior to beginning therapy;

- is capable of complying with effective contraceptive measures;

- has received both oral and written warnings of the hazards of misoprostol, risk of possible contraception failure, and danger to other women of childbearing potential if the drug is taken by mistake; and

- will begin using this product only on the second or third day of the next normal menstrual period.

Serious cardiovascular thrombotic event:

NSAIDs cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.

Diclofenac/misoprostol is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.

Serious GI bleeding, ulceration, and perforation:

NSAIDs cause an increased risk of serious 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.

For Healthcare Professionals

Applies to diclofenac / misoprostol: oral tablet

General

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

Gastrointestinal

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]

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
Postmarketing reports: Gastrointestinal (GI) perforation, GI bleeding, melena, colitis, Crohn's disease, esophageal disorder, mouth ulceration, tongue edema, dry mouth

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

Common (1% to 10%): Erythema multiforme, rash, pruritus
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]

Renal

Frequency not reported: Renal failure, glomerulonephritis membranous, glomerulonephritis minimal lesion
Postmarketing reports: Acute renal failure, renal papillary necrosis, nephritis, interstitial nephrotic syndrome, proteinuria[Ref]

Hematologic

Uncommon (0.1% to 1%): Thrombocytopenia
Rare (less than 0.1%): Agranulocytosis, anemia, aplastic anemia, coagulation time increased, ecchymosis, eosinophilia, hemolytic anemia, leukocytosis, leukopenia, lymphadenopathy, pancytopenia, decreased hematocrit[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]

Nervous system

Common (1% to 10%): Headache, dizziness
Rare (less than 0.1%): Drowsiness, headache, hyperesthesia, hypertonia, hypoesthesia, insomnia, meningitis, migraine, neuralgia, paresthesia, somnolence, stroke, tremor, confusion
Frequency not reported: Coma
Postmarketing reports: Convulsions, memory disturbance, taste disturbance[Ref]

Misoprostol:
Frequency not reported: Hyperstimulation of the uterus, amniotic fluid embolism resulting in maternal and fetal death, severe vaginal bleeding, retained placenta, pelvic pain, uterine rupture[Ref]

Misoprostol may cause abortion. It has been used outside of its approved indications to ripen the cervix, to induce labor, and to treat postpartum hemorrhage, however a major adverse effect of these uses is hyperstimulation of the uterus. Uterine rupture, amniotic fluid embolism, and severe genital bleeding have been reported.[Ref]
