Indications & Clinical Uses

Metamizole is a non‑opioid analgesic used for conditions involving acute pain and fever.

  • Acute pain: provides rapid relief of severe, short‑term pain.
  • Post‑operative pain: reduces discomfort after surgical procedures.
  • Fever: lowers elevated body temperature.
  • Colic: alleviates abdominal cramping associated with colic.

How It Works

  • Metamizole acts as a non‑opioid analgesic by inhibiting cyclooxygenase enzymes, which reduces prostaglandin synthesis. This suppression diminishes peripheral sensitization and central pain transmission, while also exerting antipyretic effects through hypothalamic temperature regulation pathways.

Side Effects

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

Common Side Effects

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

Serious or Rare Side Effects

  • Agranulocytosis: severe reduction in white blood cells, potentially life‑threatening.
  • Severe allergic reactions: including anaphylaxis and skin rash.
  • Stevens‑Johnson syndrome: rare but serious skin and mucous membrane disorder.

Precautions & Warnings

Before using Metamizole, consider the following safety measures.

  • Renal function: assess baseline kidney status.
  • Blood counts: monitor complete blood count regularly.
  • Hypersensitivity: avoid in patients with known allergy to pyrazolones.
  • Cardiovascular disease: use cautiously in patients with unstable heart conditions.
  • Hepatic impairment: adjust use if liver function is compromised.
  • Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Avoid Interactions

Metamizole can interact with other medicines; some combinations require avoidance while others need monitoring.

Major Interactions (Avoid)

  • Anticoagulants: increased risk of bleeding.
  • Other NSAIDs: heightened gastrointestinal and renal toxicity.
  • Allopurinol: elevated risk of agranulocytosis.

Moderate Interactions (Monitor Closely)

  • Diuretics: may exacerbate potassium loss.
  • Antihypertensives: potential reduction in blood pressure control.
  • Lithium: increased lithium serum concentrations.

Frequently Asked Questions

Metamizole Kalceks is an injectable pyrazolone derivative indicated for the short‑term relief of acute pain, postoperative pain, high fever and colic in adult patients when other analgesics are insufficient.

Metamizole inhibits cyclooxygenase enzymes, reducing prostaglandin synthesis. This action decreases peripheral pain signaling and central sensitization, while also acting on hypothalamic pathways to lower body temperature.

The appropriate dose of Metamizole Kalceks is determined by the prescribing clinician based on the patient’s condition, severity of symptoms, and clinical response. Dosing regimens are individualized and should follow local prescribing guidelines.

Safety of Metamizole during pregnancy and lactation has not been established. It should be avoided unless the potential benefit justifies the potential risk to the fetus or infant, and only under strict medical supervision.

To order, submit an enquiry on the Metamizole Kalceks 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 and necessary import documentation.

Metamizole offers non‑opioid analgesia with both pain‑relieving and antipyretic effects, distinguishing it from typical NSAIDs that may have stronger anti‑inflammatory activity. It is often chosen when rapid pain control is needed and when other analgesics are contraindicated, but it requires monitoring for rare blood‑related adverse events.

Metamizole Kalceks must be stored at 2‑8 °C in a refrigerator. Keep the vial in its original packaging, protect it from light, and do not freeze or shake the solution before use.

Metamizole Kalceks is supplied as an injectable solution for intramuscular or intravenous administration. The route and rate of injection are selected by the healthcare professional according to the clinical situation.

The most serious risks include agranulocytosis, a potentially fatal drop in white‑blood‑cell count, and severe allergic reactions such as anaphylaxis or Stevens‑Johnson syndrome. Immediate medical attention is required if signs of infection, rash, or breathing difficulty develop.

Metamizole is contraindicated in patients with known hypersensitivity to pyrazolones, existing agranulocytosis, severe hepatic or renal impairment, and in individuals with uncontrolled cardiovascular disease unless benefits outweigh risks.
