Diclofenac sodium 50 mg is a common formulation of the non‑steroidal anti‑inflammatory drug (NSAID) diclofenac. Below is a concise overview of its use, dosing, and safety considerations.
| Topic | Key Points |
|-------|------------|
| What it is | Diclofenac sodium is the sodium salt of diclofenac, a potent inhibitor of cyclo‑oxygenase (COX‑1 and COX‑2). It reduces prostaglandin synthesis, which lowers pain and inflammation. |
| Typical indications | • Musculoskeletal pain (e.g., osteoarthritis, rheumatoid arthritis, ankylosing spondylitis)
• Acute pain (post‑operative, dental, menstrual)
• Inflammatory conditions (e.g., tendinitis, bursitis)
• Topical forms for localized pain (e.g., muscle sprains, sports injuries). |
| Common oral dosage (50 mg tablets) | • Adults: 50 mg taken 2–4 times daily.
• Maximum recommended daily dose is usually 200 mg (though some guidelines limit it to 150 mg/day).
• Children: Dosing is age‑, weight‑, and condition‑dependent and should follow a pediatric‑approved protocol. |
| Administration | • Take with food or a full glass of water to reduce gastric irritation.
• Do not exceed the maximum daily dose.
• If using the topical gel/patch, apply to the affected area 1–2 × daily (do not cover large areas or break‑through skin). |
| Common side‑effects | • Gastro‑intestinal upset, dyspepsia, nausea, abdominal pain, heartburn.
• Headache, dizziness, and mild fatigue.
• Rarely, more serious GI events (ulcers, bleeding).
• Renal impairment or fluid retention in susceptible individuals. |
| Contraindications / cautions | • Peptic ulcer disease, active GI bleeding.
• Severe heart failure, uncontrolled hypertension, chronic kidney disease.
• Known hypersensitivity to diclofenac or other NSAIDs.
• Use with caution in pregnancy (especially 3rd trimester) and lactation. |
| Drug interactions | • Anticoagulants (warfarin, DOACs) – increased bleeding risk.
• ACE inhibitors/ARB, diuretics – potential renal compromise.
• Other NSAIDs – additive GI and renal side‑effects.
• Corticosteroids – increased GI toxicity. |
| Monitoring | • Baseline and periodic liver and kidney function tests for long‑term therapy.
• Monitor blood pressure and signs of fluid retention.
• Watch for GI bleeding symptoms (black stools, vomiting blood). |
| When to seek medical help | • Severe abdominal pain or persistent nausea/vomiting.
• Signs of GI bleeding (black/tarry stools, vomiting blood).
• Unexplained swelling, shortness of breath, chest pain.
• Sudden increase in blood pressure or edema. |
