Nolotil (Metamizole Magnesium)

Metamizole, the active ingredient in Nolotil, is a pyrazolone presented as an oral tablet for oral use. It is employed to relieve moderate to severe pain and to reduce fever in adult patients. The drug acts centrally and peripherally to provide analgesic and antipyretic effects.

GNH USA supplies Nolotil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, including major academic medical centres.

Nolotil (metamizole) is indicated for conditions involving pain and fever, acting on the prostaglandin pathway. - Acute pain: provides rapid analgesic relief in short‑term severe pain episodes. - Post‑operative pain: helps control discomfort following surgical procedures. - Fever: lowers elevated body temperature in febrile states.

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

Common Side Effects: - Nausea: mild to moderate upset stomach. - Vomiting: occasional emesis. - Dizziness: transient light‑headedness. - Headache: mild cranial discomfort. - Skin rash: mild erythema or itching. - Hypotension: occasional drop in blood pressure.

Serious or Rare Side Effects: - Agranulocytosis: severe reduction of white blood cells, potentially life‑threatening. - Severe skin reactions: such as Stevens‑Johnson syndrome. - Anaphylaxis: acute allergic response requiring emergency care. - Hepatic injury: rare liver function abnormalities. - Blood dyscrasias: other serious hematologic disorders. - Renal impairment: rare acute kidney injury.

Before initiating therapy, clinicians should evaluate patient risk factors and monitor for adverse events. - Blood count monitoring: perform baseline and periodic leukocyte counts. - Hypersensitivity: avoid in patients with known allergy to metamizole or other pyrazolones. - Renal function: use caution in patients with impaired kidney function. - Concomitant infection: monitor closely for signs of infection due to potential neutropenia. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Metamizole can interact with several medicines, requiring attention to avoid harmful effects.

Major Interactions (Avoid): - Warfarin: increased risk of bleeding. - Cytotoxic chemotherapy agents: enhanced myelosuppression. - Sulfonamide antibiotics: additive risk of agranulocytosis.

Moderate Interactions (Monitor Closely): - ACE inhibitors: possible additive hypotensive effect. - Diuretics: risk of electrolyte imbalance. - Lithium: potential alteration of serum lithium levels.
