Neurovit100 mg

Neurovit 100 mg (Vitamin B1) is indicated for the following:

Established / Approved Uses

• Prevention and treatment of thiamine deficiency, including dietary deficiency and deficiency due to malabsorption, chronic illness, or increased requirement.
• Treatment of beriberi (dry and wet forms), including infantile beriberi with acute cardiovascular collapse.
• Treatment and prevention of Wernicke's encephalopathy and Wernicke-Korsakoff syndrome, particularly in patients with chronic alcohol use disorder or severe malnutrition.
• Neuritis of pregnancy (peripheral neuropathy associated with severe vomiting/malnutrition in pregnancy).

Guideline-Supported / Adjunct Uses

• Prophylaxis against thiamine deficiency in patients receiving intravenous dextrose/glucose who have marginal thiamine status (e.g. chronic alcohol use, prolonged fasting, malnutrition), to reduce the risk of precipitating Wernicke's encephalopathy.
• Supportive therapy in cardiovascular disease attributable to thiamine deficiency (e.g. "wet" beriberi with high-output heart failure).
• Nutritional supplementation in conditions with increased thiamine requirement or loss, such as chronic dialysis, prolonged parenteral nutrition, bariatric surgery, and gastrointestinal disorders causing malabsorption.

Neurovit 100 mg is not indicated as a general-purpose analgesic, sedative, or treatment for conditions unrelated to thiamine deficiency, and unsupported claims (e.g. for unrelated neuropathies without documented deficiency) are not established indications.

Each dosage form contains Neurovit 100 mg (Vitamin B1) as the active ingredient.

• Oral tablet: commonly available as Neurovit 100 mg 100 mg tablets.
• Injection: commonly available as Neurovit 100 mg 100 mg/mL solution for intramuscular (IM) or intravenous (IV) injection.

Tablets and injections may also contain standard pharmaceutical excipients (e.g. binders, fillers for tablets; water for injection, pH-adjusting agents, and preservatives for parenteral forms), which vary by manufacturer.

Neurovit 100 mg is the hydrochloride salt of thiamine, the synthetic form of Vitamin B1, a water-soluble essential vitamin that the body cannot synthesize and must obtain from diet or supplementation.

Neurovit 100 mg is converted in the body to thiamine pyrophosphate (TPP), the biologically active coenzyme form required for carbohydrate metabolism, energy production, and normal nerve, muscle, and heart function. Deficiency of thiamine leads to disorders such as beriberi and Wernicke-Korsakoff syndrome.

Neurovit 100 mg is available as oral tablets for routine deficiency prevention and mild-to-moderate deficiency, and as injectable solution for severe deficiency, malabsorption, or emergency situations such as Wernicke's encephalopathy.

Neurovit 100 mg belongs to the therapeutic class of Vitamin B-complex preparations, specifically classified as a water-soluble vitamin (Vitamin B1) supplement used for nutritional deficiency prevention and treatment.

Neurovit 100 mg provides thiamine, which is phosphorylated in the liver and other tissues to form thiamine pyrophosphate (TPP), its active coenzyme form.

Mechanism: TPP is an essential cofactor for several key enzymes in carbohydrate and energy metabolism, including pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase. These enzymes are central to the Krebs cycle and the pentose phosphate pathway, which generate cellular energy (ATP) and support nerve conduction, muscle function, and myocardial contractility.

Deficiency effects: Thiamine deficiency impairs cellular energy metabolism, particularly in tissues with high metabolic demand such as the nervous system and heart, leading to beriberi (peripheral neuropathy, cardiac failure) and, in severe cases, Wernicke's encephalopathy (confusion, ataxia, ophthalmoplegia) or Korsakoff psychosis.

Pharmacokinetics: Oral thiamine is absorbed in the small intestine, mainly via an active, saturable carrier-mediated process at low doses and passive diffusion at higher doses; absorption is impaired in chronic alcohol use disorder and malabsorptive states. Thiamine is widely distributed, with limited body stores, and is metabolized in the liver, with excess amounts excreted unchanged in the urine. Parenteral administration bypasses intestinal absorption and is preferred when rapid repletion or malabsorption is a concern.

Clinical note: In patients with chronic alcohol use disorder or malnutrition, Neurovit 100 mg should generally be administered before or together with intravenous glucose/dextrose, as glucose administration in a thiamine-deficient patient can precipitate or worsen acute Wernicke's encephalopathy.

Neurovit 100 mg tablets are taken orally, with or without food, generally once daily unless otherwise directed. Injectable Neurovit 100 mg is given by a healthcare professional via intramuscular or slow intravenous injection; rapid IV push should be avoided due to the risk of hypersensitivity reactions. Injection should be prepared and administered using aseptic technique.

Neurovit 100 mg has no significant clinically important drug interactions at typical supplemental doses. The following points are noted:

• Furosemide and other loop diuretics: Chronic use can increase urinary thiamine loss, potentially contributing to deficiency; this is a nutritional consideration rather than a direct pharmacologic interaction requiring dose adjustment of either drug.
• Alcohol: Chronic alcohol use impairs intestinal thiamine absorption and increases thiamine requirement; it does not directly interact with administered Neurovit 100 mg but is a major cause of the deficiency states Neurovit 100 mg is used to treat.
• Intravenous glucose/dextrose: In thiamine-deficient patients, administering glucose before thiamine repletion can precipitate acute Wernicke's encephalopathy; Neurovit 100 mg should be given before or with glucose in at-risk patients (see Pharmacology and Precautions).

No dose adjustment of concomitant medications is generally required due to Neurovit 100 mg itself.

Neurovit 100 mg is generally very well tolerated, particularly with oral use. Reported adverse effects include:

Common (mostly with oral use)

• Mild gastrointestinal upset (nausea)
• Mild warmth or tingling sensation

Uncommon to Rare (more often associated with parenteral, especially IV, administration)

• Local injection-site pain, tenderness, or induration
• Sweating, weakness, restlessness
• Pruritus (itching) and skin flushing

Rare but Serious

• Hypersensitivity/anaphylactoid reactions, including urticaria, angioedema, throat tightness, and, very rarely, life-threatening anaphylaxis and cardiovascular collapse — reported predominantly with rapid intravenous administration of high doses, and more often with repeated parenteral exposure (see Precautions and Warnings).

Neurovit 100 mg is an essential vitamin and thiamine requirements increase during pregnancy and lactation. At doses within the recommended dietary allowance (RDA), Neurovit 100 mg is considered safe and is often recommended for deficient or at-risk pregnant and breastfeeding women (e.g. hyperemesis gravidarum, neuritis of pregnancy). However, at doses above the RDA, safety data are more limited, and such use should occur only if clearly needed and if the potential benefit justifies the potential risk to the fetus or infant. As with any supplement used above nutritional doses in pregnancy or lactation, a physician should be consulted before use.

The following precautions apply to the use of Neurovit 100 mg:

• Hypersensitivity reactions: Rare but potentially fatal anaphylactoid and anaphylactic reactions have been reported, almost exclusively with parenteral (especially rapid intravenous) administration, and more frequently after repeated exposure. Parenteral Neurovit 100 mg should be administered slowly, and facilities for managing anaphylaxis should be available. Consider a test dose in patients with a history of allergies or prior reactions to B-vitamin injections.
• Sequence with glucose administration: In patients with chronic alcohol use disorder or malnutrition who require intravenous glucose/dextrose, Neurovit 100 mg should be administered before or together with the glucose infusion, since glucose given first can precipitate or worsen acute Wernicke's encephalopathy.
• Route selection: Intravenous administration should be reserved for situations where oral or intramuscular routes are not feasible (e.g. severe deficiency, malabsorption, emergency treatment), and should be given slowly.
• Aluminum content (parenteral products): Some injectable formulations may contain aluminum; prolonged use in patients with renal impairment may lead to aluminum accumulation and toxicity.

Neurovit 100 mg has a wide margin of safety, as excess thiamine is generally excreted renally, and clinically significant toxicity from oral overdose is rare. Very high parenteral doses have rarely been associated with headache, irritability, and hypersensitivity-type reactions. In case of a suspected overdose, or if serious symptoms such as difficulty breathing, swelling, severe dizziness, or collapse occur, seek immediate medical attention or contact a poison control center/emergency services rather than attempting home treatment.

Store at room temperature (below 30°C), away from light and moisture. Keep out of reach of children. Injectable solution should be inspected visually for particulate matter or discoloration before use and not used if the solution is discolored or contains particles.

Elderly

No specific dose adjustment of Neurovit 100 mg is generally required in elderly patients, though they may be at higher risk of underlying thiamine deficiency due to poor dietary intake, chronic illness, or diuretic use, and may warrant closer monitoring.

Renal Impairment

No well-established dose adjustment is required; caution is advised with prolonged high-dose parenteral use due to potential aluminum accumulation (see Precautions and Warnings).

Hepatic Impairment

No well-established dose adjustment is required; patients with chronic liver disease (often related to alcohol use) frequently have increased thiamine requirements.

Alcohol Use Disorder

Patients with chronic alcohol use disorder are at particularly high risk of thiamine deficiency and Wernicke-Korsakoff syndrome and often require parenteral Neurovit 100 mg supplementation, given before or with any glucose-containing fluids.

Duration of Neurovit 100 mg therapy depends on the indication: nutritional supplementation for mild deficiency is often continued for several weeks (e.g. up to one month) or until dietary intake is adequate; treatment of beriberi is typically continued for about 2 weeks with intramuscular therapy before transitioning to oral maintenance; treatment of Wernicke's encephalopathy typically continues with daily parenteral dosing until clinical improvement and resumption of a normal diet, as directed by the treating physician. Ongoing use in high-risk patients (e.g. chronic alcohol use disorder) may be long-term, under medical supervision.

Neurovit 100 mg is classified as a water-soluble vitamin, specifically Vitamin B1 (thiamine), within the broader class of vitamin B-complex nutritional supplements.

Neurovit 100 mg supplies thiamine, which is converted to thiamine pyrophosphate (TPP), an essential coenzyme for pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase, and transketolase. These enzymes are critical to carbohydrate metabolism, ATP (energy) production, and the pentose phosphate pathway, which supports nucleic acid synthesis and maintenance of nerve and cardiac tissue function. By restoring these enzymatic pathways in deficient individuals, Neurovit 100 mg corrects the metabolic and neurological disturbances of thiamine deficiency.

A (at doses within the recommended dietary allowance); category C-equivalent caution applies at doses exceeding the RDA, as safety data are more limited.

Neurovit 100 mg is used in pediatric patients for the prevention and treatment of thiamine deficiency and beriberi, including infantile beriberi with acute cardiovascular collapse, which is treated with an initial intravenous dose followed by intramuscular maintenance dosing under close medical supervision. Oral supplementation is used for dietary deficiency, with dosing individualized by age, weight, and severity of deficiency. Safety and efficacy of specific high-dose parenteral regimens have not been as extensively studied in children as in adults, and pediatric use should be guided and supervised by a physician, particularly for injectable Neurovit 100 mg.
