Metamizole is a non‑opioid analgesic and antipyretic used in the management of pain and fever.

- Acute pain: rapid reduction of severe pain intensity. - Post‑operative pain: control of surgical pain during recovery. - Fever: effective lowering of elevated body temperature. - Visceral colic: relief of spasm‑related abdominal discomfort. - Colic and visceral pain: alleviation of pain caused by organ spasms.

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

Common Side Effects: - Injection site pain: mild discomfort at the site of administration. - Nausea: transient feeling of queasiness. - Dizziness: light‑headed sensation. - Rash: mild skin erythema.

Serious or Rare Side Effects: - Agranulocytosis: severe reduction of white blood cells, potentially life‑threatening. - Anaphylaxis: acute allergic reaction with airway compromise. - Stevens‑Johnson syndrome: severe skin and mucous membrane disorder. - Severe thrombocytopenia: marked drop in platelet count.

Use of Metamizole requires careful clinical assessment and monitoring.

- Renal function: assess baseline kidney function before use. - Hepatic function: monitor liver enzymes in patients with liver disease. - Blood counts: perform regular complete blood count to detect agranulocytosis. - Allergy history: avoid in patients with known hypersensitivity to pyrazolones. - Concomitant drugs: use caution with other myelosuppressive agents. - Store at 2‑8 °C: keep refrigerated, protect from light, do not freeze or shake.

Metamizole can interact with several medicines; some combinations should be avoided while others need close monitoring.

Major Interactions (Avoid): - Myelosuppressive chemotherapy: may exacerbate bone‑marrow suppression. - Anticoagulants (warfarin): increased bleeding risk due to platelet effects. - Other pyrazolones: additive risk of agranulocytosis. - ACE inhibitors: potential for enhanced hypotension.

Moderate Interactions (Monitor Closely): - NSAIDs: may increase gastrointestinal irritation. - Diuretics: additive hypotensive effect. - Corticosteroids: heightened risk of infection.
