What is Metamizole Sodium Monohydrate?
Metamizole, the active ingredient in Metamizol Noridem, is a pyrazolone analgesic presented as an injection solution for intramuscular and intravenous use. It treats acute pain, postoperative pain, fever, and colic in adult patients.
GNH USA supplies Metamizol Noridem as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Metamizole Sodium Monohydrate used for?
Metamizole is used for managing pain and fever through inhibition of prostaglandin synthesis and central pain modulation.
Acute pain: provides rapid analgesia for severe short‑term pain episodes. Post‑operative pain: reduces discomfort following surgical procedures. Fever: lowers elevated body temperature in febrile states. Colic: alleviates abdominal cramping associated with gastrointestinal colic.
What are the side effects of Metamizole Sodium Monohydrate?
Metamizole may cause a range of adverse reactions, from mild to severe.
Common Side Effects: - Injection site pain: mild discomfort at the site of administration. - Transient hypotension: temporary drop in blood pressure after injection. - Nausea or vomiting: gastrointestinal upset occurring shortly after dosing. - Dizziness or flushing: mild circulatory sensations.
Serious or Rare Side Effects: - Agranulocytosis: severe reduction in white blood cells, potentially life‑threatening. - Anaphylactic reaction: rapid onset of severe allergic symptoms. - Stevens‑Johnson syndrome or toxic epidermal necrolysis: serious skin reactions. - Severe blood dyscrasias: including thrombocytopenia or hemolytic anemia. - Profound hypotension: marked blood pressure fall requiring medical intervention.
What precautions apply to Metamizole Sodium Monohydrate?
Metamizole should be used with caution in specific clinical situations.
Renal impairment: assess kidney function before use. Hepatic dysfunction: monitor liver enzymes during therapy. History of blood disorders: avoid in patients with prior agranulocytosis. Concomitant NSAIDs: increase risk of gastrointestinal bleeding. Pregnancy and breastfeeding: use only if clearly needed after risk assessment. Store at ambient temperature: keep in original container, protect from light and moisture.
What does Metamizole Sodium Monohydrate interact with?
Metamizole can interact with several drug classes, requiring attention to avoid adverse outcomes.
Major Interactions (Avoid): - Bone‑marrow suppressants: may potentiate agranulocytosis. - Strong vasodilators: increase risk of severe hypotension. - Anticoagulants: elevate bleeding risk. - Sulfonamides: may heighten blood‑cell toxicity.
Moderate Interactions (Monitor Closely): - Other NSAIDs: additive gastrointestinal irritation. - Diuretics: enhanced hypotensive effect. - Certain antidepressants: potential for serotonin syndrome.
