Indications & Clinical Uses

Metamizole is used in the management of acute pain and fever, acting within the analgesic and antipyretic therapeutic classes.

  • Pain: provides rapid relief of moderate to severe acute pain.
  • Fever: reduces elevated body temperature in febrile states.
  • Post‑operative pain: controls pain following surgical procedures.

How It Works

  • Metamizole exerts its effect by non‑selectively inhibiting cyclooxygenase enzymes, which lowers prostaglandin synthesis. The reduction in prostaglandins diminishes peripheral sensitisation of nociceptors and central pain transmission, while also acting on hypothalamic thermoregulatory centers to produce antipyretic activity.

Side Effects

Metamizole may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

  • Nausea: mild gastrointestinal upset.
  • Dizziness: transient light‑headedness.
  • Hypotension: occasional drop in blood pressure after rapid injection.
  • Injection site pain: local discomfort at the administration site.

Serious or Rare Side Effects

  • Agranulocytosis: severe reduction in white blood cells.
  • Severe allergic reactions (anaphylaxis): rapid onset of systemic hypersensitivity.
  • Stevens‑Johnson syndrome: serious skin and mucous membrane disorder.

Precautions & Warnings

Before prescribing Metamizole, clinicians should consider several safety measures.

  • Assess patient history: check for prior hypersensitivity to pyrazolones.
  • Monitor blood counts: especially during prolonged therapy.
  • Avoid use in patients with known bone marrow disorders.
  • Use with caution in renal or hepatic impairment.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Metamizole can interact with other medicines; awareness of the interaction level helps guide monitoring.

Major Interactions (Avoid)

  • Concurrent use with other myelosuppressive agents: increased risk of agranulocytosis.
  • Combination with other NSAIDs: heightened gastrointestinal toxicity.
  • Co‑administration with drugs that affect platelet function: increased bleeding risk.

Moderate Interactions (Monitor Closely)

  • Interaction with anticoagulants: may potentiate anticoagulant effect.
  • Use with antihypertensives: possible additive hypotensive effect.
  • Concurrent use with drugs metabolized by CYP enzymes: potential altered plasma levels.

Frequently Asked Questions

Metamizol Noridem is indicated for the relief of moderate to severe acute pain, the reduction of fever, and the management of post‑operative pain. It is typically administered by intramuscular or intravenous injection in hospital or clinical settings.

Metamizole works by non‑selectively inhibiting cyclooxygenase enzymes, which reduces the synthesis of prostaglandins. Lower prostaglandin levels decrease peripheral nociceptor sensitisation and central pain signalling, while also acting on the hypothalamus to lower body temperature.

The specific dose and frequency of Metamizol Noridem are determined by the prescribing clinician based on the patient’s condition, age, weight, and response to therapy. Dosing information is provided on the prescription label.

Safety data for Metamizole during pregnancy and lactation are limited. It should only be used when the potential benefit justifies the potential risk to the fetus or infant, and the decision must be made by a qualified healthcare professional.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity.

Metamizole is a non‑opioid analgesic that offers rapid pain relief and antipyretic effects, often with a lower risk of gastrointestinal irritation than traditional NSAIDs. However, it carries a rare risk of agranulocytosis, which is less common with many other analgesics, so risk‑benefit assessment is essential.

Metamizol Noridem should be stored at 2‑8 °C, protected from light, and must not be frozen or shaken. Keep the product in its original packaging until use and discard any solution that appears discoloured or particulate.

Metamizol Noridem is administered by a qualified healthcare professional via intramuscular or intravenous injection. The injection should be given slowly to minimise the risk of hypotension, and the site should be monitored for local reactions.

The most serious adverse reactions include agranulocytosis, severe allergic reactions such as anaphylaxis, and rare skin disorders like Stevens‑Johnson syndrome. Patients should be instructed to seek immediate medical attention if they develop signs of infection, rash, or breathing difficulty.

Metamizol Noridem is contraindicated in individuals with known hypersensitivity to pyrazolones or Metamizole, patients with existing bone‑marrow suppression, and those with severe hepatic or renal impairment where the risk outweighs benefit. It should also be avoided in patients receiving other myelosuppressive therapies.
