Nolotil (Metamizole Magnesium)

Metamizole magnesium, the active ingredient in Nolotil, is a pyrazolone derivative presented as an injection solution for intramuscular and intravenous use. It provides analgesic and antipyretic effects for adult patients experiencing pain, fever, postoperative discomfort, and colic in clinical settings, and is commonly used in acute care environments.

GNH USA supplies Nolotil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, with a focus on quality assurance and regulatory compliance.

Nolotil (metamizole magnesium) is employed to manage pain and fever through inhibition of prostaglandin synthesis.

- Pain: Provides analgesic relief for moderate to severe acute pain. - Fever: Reduces elevated body temperature in febrile conditions. - Postoperative pain: Controls pain following surgical procedures. - Colic: Alleviates visceral pain associated with intestinal colic.

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

Common Side Effects: - Nausea: mild gastrointestinal upset. - Vomiting: occasional emesis. - Dizziness: transient light‑headedness. - Hypotension: temporary drop in blood pressure. - Injection site reactions: pain, redness or swelling at the administration site.

Serious or Rare Side Effects: - Agranulocytosis: severe reduction of white blood cells, potentially life‑threatening. - Anaphylaxis: acute allergic reaction with respiratory distress. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hepatic dysfunction: elevated liver enzymes indicating liver stress. - Hemolytic anemia: destruction of red blood cells.

When using Nolotil, several precautions should be observed to ensure safe administration. - Patient assessment: evaluate for history of blood dyscrasias before initiating therapy. - Monitoring: conduct regular complete blood counts during prolonged treatment. - Renal function: adjust use in patients with impaired kidney function. - Hepatic function: use cautiously in individuals with liver disease. - Drug interactions: avoid concomitant use with other myelosuppressive agents. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Metamizole magnesium can interact with other medicines, influencing efficacy or safety.

Major Interactions (Avoid): - Anticoagulants: may increase bleeding risk. - Other pyrazolones: additive risk of agranulocytosis.

Moderate Interactions (Monitor Closely): - NSAIDs: potential additive gastrointestinal irritation. - Immunosuppressants: may enhance myelosuppression. - ACE inhibitors: possible potentiation of hypotensive effects.
