Neurobion Tablet Uses, Dosage and Side Effects in Pakistan
- Neurobion = B1 (thiamine 100mg) + B6 (pyridoxine 200mg) + B12 (cyanocobalamin 200mcg) by Merck Pakistan
- Used for peripheral neuropathy, diabetic nerve damage, carpal tunnel and B-vitamin deficiency
- Higher B6 dose (200mg) than Neuromet (100mg) — greater carpal tunnel benefit but higher B6 toxicity risk at 2+ tablets/day
- Injection preferred for severe deficiency, malabsorption, or acute neurological symptoms
- Takes 4–6 weeks for initial improvement; 3–6 months for full benefit in neuropathy
What Is Neurobion?
Neurobion is a neurotrophic B-vitamin combination tablet manufactured by Merck Pakistan, containing thiamine (B1) 100mg + pyridoxine (B6) 200mg + cyanocobalamin (B12) 200mcg. It is one of the best-known nerve vitamin products in Pakistan, available as both oral tablets and intramuscular injection (Neurobion Forte injection).
The formulation is pharmacologically identical to Neuromet and similar B1+B6+B12 combinations — the primary difference is the higher B6 dose (200mg vs 100mg in Neuromet). This higher B6 provides stronger benefit for conditions requiring high-dose pyridoxine (like carpal tunnel syndrome) but also carries a slightly higher risk of B6-induced neuropathy if doses are stacked.

Neurobion Uses
1. Diabetic Peripheral Neuropathy
The most common indication in Pakistan. Diabetics — especially those on metformin — are frequently deficient in B12, and often B1 and B6. Neurobion addresses all three deficiencies simultaneously. Results are gradual over 3–6 months; blood sugar control must be optimised concurrently for maximum nerve protection.
2. Peripheral Neuropathy (Various Causes)
Useful for neuropathy from: alcohol use (B1 deficiency is primary), tuberculosis medication (INH depletes B6), chronic kidney disease, hypothyroidism and malnutrition. The combination format covers the most common B-vitamin deficiencies causing peripheral nerve damage.
3. Carpal Tunnel Syndrome
Neurobion's 200mg B6 per tablet is particularly useful for carpal tunnel syndrome (CTS) — high-dose pyridoxine has evidence for reducing CTS symptoms including pain, numbness and tingling in the hand from median nerve compression. The higher B6 in Neurobion vs Neuromet may provide stronger benefit here, but limit to 1 tablet/day to stay within safe B6 limits.
4. Back Pain and Sciatica (Adjunct)
Neurobion is frequently prescribed as an adjunct for back pain and sciatica in Pakistan. The rationale: B vitamins reduce neuropathic pain transmission and support nerve health in compressed or inflamed nerves. The evidence for Neurobion in acute musculoskeletal pain is modest — it is most useful when B-vitamin deficiency is contributing to symptoms.
5. General B-Vitamin Deficiency
Fatigue, weakness, mouth ulcers, glossitis (inflamed tongue), poor concentration and peripheral tingling from dietary B-vitamin inadequacy respond well to Neurobion supplementation.
Dosage
| Indication | Dose |
| Mild deficiency / maintenance | 1 tablet once daily with food |
| Diabetic neuropathy | 1 tablet twice daily |
| Carpal tunnel syndrome | 1 tablet daily (200mg B6 per tablet is sufficient) |
| Acute therapy | Up to 3 tablets daily for short courses (1–2 weeks) |
| Duration | 3–6 months minimum for neuropathy |
Important: Do not routinely take 2+ tablets daily long-term without medical guidance — cumulative B6 above 200–400mg/day chronically approaches the paradoxical neuropathy threshold.
Neurobion Injection — When to Use It
The Neurobion Forte IM injection (containing B1 100mg + B6 100mg + B12 1000mcg per 3ml ampoule) is preferred over tablets when:
- Oral absorption is impaired: pernicious anaemia (lack of intrinsic factor), post-gastrectomy, malabsorption syndromes (coeliac, Crohn's)
- Severe/acute deficiency requiring rapid repletion
- Severe B12 deficiency with neurological signs (subacute combined degeneration, severe neuropathy)
- Patient non-compliance with oral tablets
For routine diabetic neuropathy and mild-moderate deficiency, oral tablets are the preferred first-line route — injections are reserved for the above indications.

Conclusion
Neurobion (B1+B6+B12 by Merck Pakistan) is functionally very similar to Neuromet and other B1+B6+B12 combinations — but contains double the B6 dose (200mg vs 100mg). This makes it slightly more potent for carpal tunnel syndrome but requires more caution about daily dose stacking. For diabetic neuropathy and routine B-vitamin deficiency, either brand is appropriate. The Neurobion Forte injection is a valuable option when oral absorption is impaired. Allow 3–6 months of consistent daily use before assessing full efficacy in neuropathy.
Frequently Asked Questions
What is the difference between Neurobion and Neuromet?
Both have B1 100mg + B12 200mcg. The difference: Neurobion has B6 200mg; Neuromet has B6 100mg. Neurobion's higher B6 is better for carpal tunnel. Neuromet's lower B6 carries less neuropathy risk at higher doses. For most patients, both are equivalent for routine nerve pain.
When should I take Neurobion injection instead of tablets?
Injection is preferred for: impaired oral absorption (pernicious anaemia, post-surgery), severe B12 deficiency with neurological signs, or acute rapid repletion need. Oral tablets are first choice for routine diabetic neuropathy and mild-moderate deficiency.
How long does Neurobion take to work for nerve pain?
4–6 weeks for initial improvement; 3–6 months for full benefit in diabetic neuropathy. Myelin repair is slow — consistency every day is essential. Don't assess efficacy until 6–8 weeks of daily use.
Can Neurobion cause nerve damage from too much B6?
Yes — at 200mg B6 per tablet, taking 2+ tablets daily long-term approaches the threshold for B6-induced sensory neuropathy. Stick to 1 tablet daily for maintenance. Do not combine with other B6-containing supplements.
Is Neurobion useful for general tiredness?
Yes — if the tiredness is from B-vitamin deficiency (common in Pakistan). B vitamins support energy metabolism and red blood cell production. For persistent fatigue from other causes (thyroid, anaemia, depression), medical evaluation is needed — Neurobion won't address the root cause.
