Nolotil (Metamizole Magnesium)

Metamizole Magnesium, the active ingredient in Nolotil, is a pyrazolone analgesic presented as an oral formulation for oral use. It is employed to relieve moderate to severe pain and to reduce fever in adult patients. The drug exerts its effect by inhibiting cyclooxygenase enzymes, leading to decreased prostaglandin synthesis, which contributes to its analgesic and antipyretic properties.

GNH India supplies Nolotil as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. Our distribution network ensures consistent quality and regulatory compliance across multiple markets.

Indications & Clinical Uses

Nolotil (metamizole magnesium) is used in the management of pain and fever, acting on inflammatory pathways.

  • Acute pain: provides effective relief of severe or postoperative pain.
  • Fever: reduces elevated body temperature in febrile conditions.
  • Visceral colicky pain: alleviates spasm‑related abdominal discomfort.

How It Works

  • Metamizole magnesium inhibits cyclooxygenase enzymes, which reduces the synthesis of prostaglandins involved in pain signaling and thermoregulation. The resulting decrease in prostaglandin levels produces central analgesic effects and lowers body temperature, providing both pain relief and antipyretic action.

Side Effects

Metamizole magnesium may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects

  • Nausea: mild to moderate stomach upset.
  • Dizziness: transient light‑headedness.
  • Skin rash: mild erythematous reactions.

Serious or Rare Side Effects

  • Agranulocytosis: severe reduction of white blood cells.
  • Aplastic anemia: bone‑marrow failure leading to pancytopenia.
  • Severe cutaneous reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Precautions & Warnings

Before prescribing Nolotil, clinicians should consider several safety measures.

  • Blood count monitoring: perform baseline and periodic hematology tests.
  • Hypersensitivity avoidance: do not use in patients with known allergy to metamizole.
  • Renal/hepatic caution: adjust use in patients with impaired kidney or liver function.
  • Concomitant myelosuppressants: avoid combining with other bone‑marrow suppressing agents.
  • Pediatric use: generally contraindicated in children under three years of age.
  • Store below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Metamizole magnesium can interact with other medicines, requiring careful assessment.

Major Interactions (Avoid)

  • Myelosuppressive agents: increased risk of severe blood dyscrasias.
  • ACE inhibitors: potentiation of hypotensive effects.
  • Anticoagulants: heightened bleeding tendency.

Moderate Interactions (Monitor Closely)

  • NSAIDs: additive gastrointestinal irritation.
  • Alcohol: enhanced central nervous system depression.
  • CYP450 substrates: possible alteration of metabolism for certain drugs.

Frequently Asked Questions

Nolotil contains metamizole magnesium and is indicated for the relief of moderate to severe pain and for the reduction of fever. It is commonly prescribed for acute postoperative pain, severe musculoskeletal pain, and febrile states where rapid antipyretic action is required.

Metamizole magnesium works by inhibiting cyclooxygenase enzymes, which leads to a decrease in prostaglandin production. Lower prostaglandin levels reduce pain signal transmission and lower the hypothalamic set‑point for body temperature, providing both analgesic and antipyretic effects.

The prescribing physician determines the appropriate dose of Nolotil based on the individual’s clinical condition, severity of pain or fever, age, weight, and any comorbidities. Dosage regimens are tailored to each patient and should follow the prescriber’s instructions.

Safety data for metamizole magnesium in pregnancy and lactation are limited, and the product is classified as having an unknown pregnancy category. It should only be used when the potential benefit justifies the potential risk to the fetus or infant, and under medical supervision.

To place an order, submit an enquiry on the Nolotil product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams across international markets, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Compared with non‑steroidal anti‑inflammatory drugs (NSAIDs), Nolotil offers potent analgesia with less gastric irritation but carries a higher risk of blood‑related adverse events. Unlike opioids, it does not cause respiratory depression, making it a useful alternative for certain acute pain scenarios.

Nolotil should be stored below 25 °C in a dry environment. Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure that the container is tightly closed to maintain stability.

Nolotil is administered orally. The tablets or capsules are taken with a full glass of water, preferably after a meal to reduce gastrointestinal discomfort. The exact route and timing should follow the prescribing clinician’s directions.

The most serious risks include agranulocytosis and other severe blood dyscrasias, which can lead to life‑threatening infections. Patients should be monitored for signs of infection, unexplained fever, or unusual bleeding, and immediate medical attention is required if such symptoms appear.

Nolotil should be avoided in individuals with known hypersensitivity to metamizole, those with existing severe bone‑marrow suppression, children under three years of age, and patients for whom the risk of agranulocytosis outweighs the therapeutic benefit. Caution is also advised in pregnant or lactating women.
