Diclofenac Sodium + Misoprostol: Brands, Price & Uses in Bangladesh

Established / FDA-Approved Uses

• Osteoarthritis — for relief of the signs and symptoms of osteoarthritis in adult patients who, in the judgment of their physician, are at high risk of developing NSAID-induced gastric or duodenal ulcers and who require an NSAID.
• Rheumatoid arthritis — for relief of the signs and symptoms of rheumatoid arthritis in adult patients at high risk for NSAID-induced gastric or duodenal ulcers and who require an NSAID.

Diclofenac Sodium + Misoprostol is specifically indicated for patients who need ongoing NSAID therapy for arthritis and who are at elevated risk of NSAID-associated gastrointestinal ulceration (e.g., older age, prior peptic ulcer disease, concomitant corticosteroid, anticoagulant, or antiplatelet use). It is not a first-line analgesic for patients without this elevated GI risk, since it commits the patient to an additional medication (misoprostol) and its associated side effects.

Diclofenac Sodium + Misoprostol is not indicated for the initial treatment of acute pain, and it is not an abortifacient medication approved for pregnancy termination, despite the pharmacologic activity of its misoprostol component (see Contraindications and Pregnancy and Lactation).

General Principles

Use the lowest effective dose of Diclofenac Sodium + Misoprostol for the shortest duration consistent with the individual patient's treatment goals, and reassess the need for continued NSAID therapy periodically.

Dose Adjustment

• When a CYP2C9 inhibitor cannot be avoided, limit total diclofenac exposure to 100 mg/day.
• Misoprostol component should not exceed 200 mcg per single dose or 800 mcg/day total.
• Use the lowest available dose in patients with hepatic impairment; avoid in severe hepatic impairment.
• Use with caution and monitor renal function in patients with renal impairment (see Use in Special Populations).

Diclofenac Sodium + Misoprostol should be swallowed whole with food or immediately after meals, and not crushed, split, or chewed, since the diclofenac core is delayed-release.

Very Common

• Diarrhea (up to ~19%) and abdominal pain (up to ~21%) — most often occur early in treatment (first 2–7 days) and are typically dose-related; magnesium antacids should be avoided as they worsen diarrhea.
• Dyspepsia, nausea, flatulence, gastritis, vomiting, constipation.

Common

• Headache, dizziness.
• Menstrual disorders in women — dysmenorrhea, menorrhagia, or intermenstrual/vaginal bleeding.
• Mild, usually asymptomatic elevation of liver transaminases.

Serious (Less Common but Important)

• Gastrointestinal bleeding, ulceration, or perforation (see Precautions and Warnings).
• Cardiovascular thrombotic events — myocardial infarction, stroke (see Precautions and Warnings).
• Severe skin reactions — Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS syndrome.
• Hepatotoxicity, including rare cases of liver failure.
• Renal impairment, including papillary necrosis with long-term use.
• Anaphylactic reactions.
• Severe dehydration from profound diarrhea (rare).

Patients should seek prompt medical attention for signs of GI bleeding (black stools, blood in vomit), chest pain, sudden weakness, shortness of breath, jaundice, severe rash, or unusual bruising/bleeding while taking Diclofenac Sodium + Misoprostol.
