Diclofenac Sodium and Misoprostol

DICLOFENAC SODIUM AND MISOPROSTOL

Standard Dose
2 DOSAGE AND ADMINISTRATION 2.1 Important Dosage Information • Carefully consider the potential benefits and risks of diclofenac sodium and misoprostol delayed-release tablets and other treatment options before deciding to use diclofenac sodium and misoprostol delayed-release tablets. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. • After observing the response to initial therapy with diclofenac sodium and misoprostol delayed-release tablets, the dose and frequency should be adjusted to suit an individual patient’s needs. • Diclofenac sodium and misoprostol delayed-release tablets are not recommended for patients who would not receive the appropriate dosage of both active ingredients. • Diclofenac sodium and misoprostol delayed-release tablets, a fixed combination product, are administered as diclofenac sodium and misoprostol delayed-release tablets (50 mg diclofenac sodium/0.2 mg misoprostol) or as diclofenac sodium and misoprostol delayed-release tablets (75 mg diclofenac sodium/0.2 mg misoprostol). 2.2 Recommended Dosage in Patients with Osteoarthritis The recommended dosage for the treatment of osteoarthritis for maximal GI mucosal protection is diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg three times a day. For patients who experience intolerance, diclofenac sodium and misoprostol delayed-release tablets 75 mg/0.2 mg two times a day or diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg two times a day can be used, but these dosages are less effective in preventing ulcers. A daily dosage of diclofenac sodium greater than 150 mg/day is not recommended. Daily doses of the components delivered with these regimens are as follows: 2.3 Recommended Dosage in Patients with Rheumatoid Arthritis The recommended dosage for the treatment of rheumatoid arthritis is diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg three or four times a day. For patients who experience intolerance, diclofenac sodium and misoprostol delayed-release tablets 75 mg/0.2 mg two times a day or diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg two times a day can be used, but are less effective in preventing ulcers. A daily dosage of diclofenac sodium greater than 200 mg/day is not recommended. Daily doses of the components delivered with these regimens are as follows: 2.4 Additional Dosage Recommendations Diclofenac sodium and misoprostol delayed-release tablets contain misoprostol, which provides protection against gastric and duodenal ulcers [see Clinical Studies (14)]. For gastric ulcer prevention, the 200 mcg four and three times a day regimens are therapeutically equivalent, but more protective than the two times a day regimen. For duodenal ulcer prevention, the four times a day regimen is more protective than the three or two times a day regimens. However, the four times a day regimen is less well tolerated than the three times a day regimen because of usually self-limited diarrhea related to the misoprostol dose [see Adverse Reactions (6.1)], and the two times a day regimen may be better tolerated than three times a day in some patients. Dosages may be individualized using the separate products (misoprostol and diclofenac sodium), after which the patient may be switched to the appropriate diclofenac sodium and misoprostol delayed-release tablets dosage. If clinically indicated, misoprostol co-therapy with diclofenac sodium and misoprostol delayedrelease tablets to optimize the misoprostol dose and/or frequency of administration, may be appropriate. Do not exceed a total misoprostol dose of 800 mcg/day and do not administer more than 200 mcg of misoprostol at any one time. When concomitant use of CYP2C9 inhibitors is necessary, the maximum total daily dose of diclofenac is 100 mg per day. Do not exceed a dosage of diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg twice daily [see Drug Interactions (7)]. For additional information, refer to the Prescribing Information for the individual products of diclofenac sodium and misoprostol. Use the lowest effective dosage for shortest duration consistent with individual patient treatment goals (2) OA: 100 to 150 mg diclofenac/400 to 600 mcg misoprostol per day, divided for administration two or three times a day. Dose of diclofenac higher than 150 mg/day is not recommended (2) RA: 100 to 200 mg diclofenac/400 to 800 mcg misoprostol per day, divided for administration two, three or four times a day. Dose of diclofenac higher than 225 mg/day is not recommended (2) 1 2 3

Boxed Warning

WARNING: RISK OF UTERINE RUPTURE, ABORTION, PREMATURE BIRTH, BIRTH DEFECTS; AND SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS WARNING: RISK OF UTERINE RUPTURE, ABORTION, PREMATURE BIRTH, BIRTH DEFECTS; SERIOUS CARDIOVASCULAR EVENTS; AND SERIOUS GASTROINTESTINAL EVENTS Uterine Rupture, Abortion, Premature Birth, and Birth Defects • Administration of misoprostol, a component of diclofenac sodium and misoprostol delayed-release tablets, 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 [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1)]. • Diclofenac sodium and misoprostol delayed-release tablets are contraindicated in pregnancy [see Contraindications (4)] 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 [see Warnings and Precautions (5.1)]. • If diclofenac sodium and misoprostol delayed-release tablets are prescribed, verify the pregnancy status of females of reproductive potential prior to initiation of treatment and advise them to use effective contraception during treatment [see Use in Specific Populations (8.3)]. Cardiovascular Thrombotic Events • 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 [see Warnings and Precautions (5.2)]. • Diclofenac sodium and misoprostol delayed-release tablets are contraindicated in the setting of coronary artery bypass graft (CABG) surgery [see Contraindications (4) and Warnings and Precautions (5.2)]. Gastrointestinal Bleeding, Ulceration, and Perforation • 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 [see Warnings and Precautions (5.3)].

Monitoring

  • • 5 WARNINGS AND PRECAUTIONS Embryo-Fetal Toxicity with NSAIDs: Use of NSAIDs, including diclofenac in women at about 20 weeks gestation and later in pregnancy may cause oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus.
  • • (4, 5.1, 8.1) Hepatotoxicity : Inform patients of warning signs and symptoms of hepatotoxicity.
  • • Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop ( 5.3 ) Hypertension : Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs.
