Indications & Clinical Uses

Diclofenac Sodium is an NSAID that alleviates pain and inflammation in various musculoskeletal and postoperative conditions.

  • Acute pain: provides rapid relief of moderate to severe pain associated with injury or surgery.
  • Inflammatory arthritis: reduces joint swelling and improves mobility in conditions such as osteoarthritis and rheumatoid arthritis.
  • Postoperative pain: controls pain and inflammation following surgical procedures.
  • Musculoskeletal injuries: alleviates pain and inflammation in sprains, strains and soft‑tissue injuries.

How It Works

  • Diclofenac Sodium exerts its anti‑inflammatory and analgesic effects by reversibly inhibiting cyclooxygenase (COX‑1 and COX‑2) enzymes, which decreases the synthesis of prostaglandins involved in pain signaling, fever and inflammation. The reduction of prostaglandin levels leads to diminished peripheral sensitization and edema at the site of injury. Additionally, COX inhibition modestly reduces platelet aggregation, contributing to its overall pharmacodynamic profile in patients.

Side Effects

Diclofenac Sodium injection may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

  • Gastrointestinal discomfort: nausea, dyspepsia or abdominal pain.
  • Injection site reactions: redness, swelling or mild pain at the intramuscular site.
  • Headache: transient mild to moderate headache.

Serious or Rare Side Effects

  • Severe gastrointestinal ulceration or bleeding.
  • Hepatotoxicity: elevated liver enzymes or hepatitis.
  • Anaphylaxis: severe allergic reaction with airway compromise.

Precautions & Warnings

When using Diclofenac Sodium injectable, clinicians should observe several precautions to minimize risk.

  • Assess renal function: avoid use in patients with severe renal impairment.
  • Monitor hepatic enzymes: use cautiously in those with liver disease.
  • Evaluate cardiovascular risk: contraindicated in patients with recent myocardial infarction or uncontrolled hypertension.
  • Use gastrointestinal protection: consider proton pump inhibitor in patients with ulcer history.
  • Avoid in hypersensitivity: discontinue if signs of allergic reaction appear.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Diclofenac Sodium may interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

  • Anticoagulants (e.g., warfarin): increased bleeding risk.
  • Other NSAIDs or COX‑2 inhibitors: heightened gastrointestinal toxicity.
  • Lithium: elevated lithium serum levels.

Moderate Interactions (Monitor Closely)

  • ACE inhibitors or ARBs: possible reduction in renal function.
  • Diuretics: risk of renal impairment and electrolyte imbalance.
  • Methotrexate: decreased clearance leading to toxicity.

Frequently Asked Questions

Naklofen contains diclofenac sodium and is indicated for the relief of moderate to severe pain, reduction of inflammation, and control of postoperative discomfort. It is commonly employed in musculoskeletal disorders, acute injuries, and after surgical procedures where an injectable NSAID is appropriate.

Diclofenac Sodium works by reversibly inhibiting cyclooxygenase‑1 and cyclooxygenase‑2 enzymes, which reduces the production of prostaglandins. Lower prostaglandin levels diminish pain signaling, fever, and inflammation, leading to decreased swelling and improved comfort at the affected site.

The specific dose and frequency of Naklofen are determined by the prescribing clinician based on the patient’s condition, severity of symptoms, and overall health status. Healthcare professionals follow local prescribing guidelines and adjust the regimen as needed.

Safety data for diclofenac sodium during pregnancy and lactation are limited, and the product is generally classified as contraindicated or to be used only if the potential benefit justifies the risk. Women who are pregnant, planning pregnancy, or breastfeeding should discuss alternatives with their healthcare provider.

To order Naklofen, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including cold‑chain if needed) and any required import documentation.

Naklofen, as an injectable formulation of diclofenac, offers rapid systemic exposure compared with oral NSAIDs, which can be advantageous for acute postoperative pain. Its COX inhibition profile is similar to other non‑selective NSAIDs, but the intramuscular route may provide quicker onset while still sharing the same safety considerations regarding gastrointestinal, renal and cardiovascular effects.

Naklofen must be stored at 2‑8 °C (refrigerated). Keep the vials in their original packaging, protect them from light, and avoid freezing or shaking the solution. If the product reaches room temperature for a short period, it may be used, but it should be returned to refrigeration promptly.

Naklofen is administered by a qualified healthcare professional as an intramuscular injection. The injection site is typically a large muscle such as the gluteus maximus or deltoid. Proper aseptic technique and dosage calculation by the prescriber are essential to ensure safety and efficacy.

Serious adverse reactions include severe gastrointestinal bleeding or ulceration, hepatotoxicity (elevated liver enzymes or hepatitis), anaphylactic shock, and cardiovascular events such as myocardial infarction or stroke. Patients should be monitored for signs of these conditions, and treatment should be stopped immediately if they occur.

Naklofen is contraindicated in patients with known hypersensitivity to diclofenac or other NSAIDs, those with active gastrointestinal ulceration or bleeding, severe renal or hepatic impairment, and individuals who have experienced a recent myocardial infarction or uncontrolled hypertension. Use should also be avoided in pregnancy unless clearly justified.
