Milgamma N (Thiamine Hydrochloride, Cyanocobalamin, Pyridoxine Hydrochloride)

Milgamma N is used to correct vitamin B deficiencies and the neurological disorders that result from them.

• Vitamin B1, B6 and B12 deficiency: restores normal levels of essential B‑vitamins and supports metabolic functions.
• Peripheral neuropathy due to vitamin B deficiency: alleviates nerve pain and improves sensory function.
• Wernicke's encephalopathy: provides rapid replenishment of thiamine to prevent neurological deterioration.

• Milgamma N delivers thiamine, pyridoxine and cyanocobalamin, which are converted intracellularly to thiamine‑pyrophosphate, pyridoxal‑phosphate and methylcobalamin. These co‑enzymes act as essential catalysts in carbohydrate metabolism, amino‑acid transamination, and myelin synthesis, thereby supporting neuronal function and energy production.

Adverse reactions may occur following intramuscular administration of Milgamma N.

Common Side Effects

• Pain or irritation at the injection site
• Mild fever or chills
• Nausea or upset stomach
• Headache or dizziness
• Transient flushing or warmth

Serious or Rare Side Effects

• Anaphylactic reaction or severe hypersensitivity
• Sudden drop in blood pressure (hypotension)
• Stevens‑Johnson syndrome or severe skin rash
• Hemolytic anemia or severe thrombocytopenia
• Serum sickness‑like reaction

Milgamma N should be used with careful clinical assessment.

• Assess baseline vitamin B levels: confirm deficiency before initiating therapy.
• Monitor for allergic reactions: observe patients after injection for signs of hypersensitivity.
• Use caution in renal impairment: adjust dosing if renal function is compromised.
• Avoid in known hypersensitivity to any component: discontinue if reaction occurs.
• Store at 2‑8 °C: keep refrigerated, protect from light, do not freeze or shake.

Milgamma N may interact with other medicines that affect vitamin metabolism or absorption.

Major Interactions (Avoid)

• Levodopa: pyridoxine can reduce levodopa efficacy.
• Methotrexate: concurrent high‑dose B‑vitamins may increase toxicity.
• Phenytoin: may lower vitamin B levels, reducing therapeutic benefit.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: may alter vitamin B metabolism.
• Antacids containing aluminum or magnesium: can impair absorption of B‑vitamins.
• Diuretics: may increase renal excretion of water‑soluble vitamins.
