What is Metamizole Sodium Monohydrate used for?
Metamizole is a non‑opioid analgesic and antipyretic that acts on pain‑related and febrile pathways.
Acute pain: provides rapid relief of severe short‑term pain such as injury or trauma. Fever: lowers elevated body temperature in infectious or inflammatory conditions. Post‑operative pain: helps control pain after surgical procedures. Colic: eases visceral pain associated with gastrointestinal spasm.
What are the side effects of Metamizole Sodium Monohydrate?
Metamizole may cause a range of adverse reactions, from mild to severe.
Common Side Effects: - Nausea: occasional upset stomach. - Vomiting: occasional emesis. - Dizziness: transient light‑headedness. - Headache: mild to moderate. - Skin rash: mild erythema or itching. - Hypotension: transient low blood pressure.
Serious or Rare Side Effects: - Agranulocytosis: severe reduction in white blood cells. - Severe allergic reactions: anaphylaxis or angioedema. - Blood dyscrasias: thrombocytopenia or hemolytic anemia. - Hepatic enzyme elevation: possible liver injury. - Stevens‑Johnson syndrome: severe skin reaction. - Anaphylactic shock: life‑threatening hypersensitivity.
What precautions apply to Metamizole Sodium Monohydrate?
Before prescribing Metamizole, clinicians should consider several safety measures.
Assess renal function: adjust use in patients with impaired kidneys. Monitor blood counts: periodic CBC to detect agranulocytosis. Avoid in known hypersensitivity: contraindicated for patients allergic to pyrazolones. Use caution in the elderly: increased risk of hypotension and renal effects. Avoid concomitant use with other NSAIDs: higher risk of gastrointestinal bleeding. Store at room temperature: keep in the original pack, protect from moisture.
What does Metamizole Sodium Monohydrate interact with?
Metamizole can interact with other medicines, requiring attention to avoid adverse outcomes.
Major Interactions (Avoid): - Myelosuppressive agents: combined use may exacerbate bone‑marrow suppression. - Sulfonamides: increased risk of severe blood dyscrasias. - Anticoagulants: may enhance bleeding tendency.
Moderate Interactions (Monitor Closely): - NSAIDs: additive gastrointestinal irritation. - Diuretics: potential for reduced renal perfusion. - ACE inhibitors: possible additive hypotensive effect.
