Novalgin (Metamizole Sodium Monohydrate)

Metamizole Sodium Monohydrate, the active ingredient in Novalgin, is a pyrazolone presented as a rectal formulation for analgesic and antipyretic use. It is employed to relieve moderate to severe pain and to reduce fever in adult patients. The drug is commonly used in clinical settings where rapid onset of pain relief is required.

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

Novalgin (metamizole sodium monohydrate) is used for pain and fever management within the pyrazolone analgesic class.

Pain: provides effective relief of moderate to severe acute pain. Fever: reduces elevated body temperature in febrile conditions. Post‑operative pain: helps control pain following surgical procedures.

Novalgin may cause a range of adverse reactions, from mild to severe. Awareness of these effects helps clinicians monitor patients appropriately.

Common Side Effects: - Nausea: mild to moderate upset stomach. - Vomiting: occasional episodes after administration. - Dizziness: transient light‑headedness. - Hypotension: drop in blood pressure, especially with rapid absorption. - Skin rash: mild erythema or itching.

Serious or Rare Side Effects: - Agranulocytosis: severe reduction in white blood cells, requiring immediate medical attention. - Anaphylactic reaction: sudden, life‑threatening allergic response. - Stevens‑Johnson syndrome: severe skin and mucous membrane disorder. - Hepatic injury: abnormal liver function tests. - Blood dyscrasias: other serious blood cell abnormalities.

Before prescribing Novalgin, clinicians should consider several safety measures.

Assess renal function: adjust use in severe renal impairment. Monitor blood counts: risk of agranulocytosis warrants periodic CBC. Avoid in known hypersensitivity: contraindicated for patients with prior metamizole reactions. Use with caution in elderly: increased sensitivity to hypotensive effects. Avoid concomitant use with other pyrazolones or NSAIDs: may increase toxicity. Store at ambient temperature: keep in original container, protect from moisture and light.

Novalgin can interact with other medicines, requiring careful assessment.

Major Interactions (Avoid): - Concurrent pyrazolones: additive toxicity and heightened risk of blood dyscrasias. - Co‑administration with bone‑marrow suppressing agents (e.g., chemotherapy): may exacerbate hematologic suppression.

Moderate Interactions (Monitor Closely): - NSAIDs: may increase gastrointestinal irritation. - ACE inhibitors: potential enhancement of hypotensive effect. - Lithium: possible increase in serum lithium concentrations.
