Neuro-B is a high-potency prescription vitamin combination containing Vitamin B1, B6, and B12. It is primarily used to treat and prevent deficiencies of these essential neurotropic vitamins, which play a critical role in nerve health and the regeneration of nerve fibers. Produced by Square Pharmaceuticals PLC, it is a leading brand in Bangladesh for managing nerve-related pain and neurological disorders. Here is a clear, updated guide for 2026.
What is Neuro-B Used For?
Neuro-B contains a specific combination of Vitamin B1 (100 mg), B6 (200 mg), and B12 (200 mcg) and is prescribed mainly for:
-
Neuropathy: Treatment of polyneuropathy of various origins, including diabetic, alcoholic, or toxic neuropathies.
-
Nerve Inflammation: Management of Neuritis and Neuralgia (nerve pain).
-
Pain Syndromes: Relief from Lumbago (lower back pain), Sciatica, Myalgia, and Cervical syndrome.
-
Neurological Conditions: Supportive treatment in facial paresis, Trigeminal neuralgia, and Intercostal neuralgia.
-
Shingles: Pain management during and after Herpes Zoster infections.
Key Reminder: Neuro-B helps nourish and repair damaged nerves but is not a direct painkiller. For a deeper look at how B vitamins support nerve metabolism, you can review the clinical profile on DrugBank.
Dosage
The dosage is typically determined by the severity of the deficiency or condition:
-
Standard Adult Dose: Usually 1 to 3 tablets daily or as directed by a physician.
-
Administration: Tablets should be swallowed whole with water. It is best taken with or after meals to ensure optimal absorption and reduce any potential stomach discomfort.
-
Duration: The length of treatment varies; chronic nerve conditions may require several months of therapy.
Common Side Effects
Neuro-B is generally very well-tolerated since it consists of water-soluble vitamins. However, rare side effects may include:
-
Allergic reactions (rash, hives, or itching)
-
Mild gastrointestinal upset (nausea or stomach pain)
-
Reddish-colored urine (due to Vitamin B12, which is harmless)
Important 2026 Safety Update: High doses of Vitamin B6 (Pyridoxine) over a very long period can occasionally lead to sensory neuropathy. According to updates in the Journal of Neurology, patients should not exceed the prescribed dose to avoid potential nerve irritation from over-supplementation.
Important Warnings & Precautions
-
Levodopa Interaction: Vitamin B6 can reduce the effectiveness of Levodopa (used for Parkinson’s disease). Consult your doctor if you are on this medication.
-
B12 Diagnosis: Cyanocobalamin should not be used for optic neuropathies (like Leber’s disease) or before a full diagnosis of anemia is established.
-
Allergies: Do not use if you have a known hypersensitivity to Thiamine, Pyridoxine, or Cyanocobalamin.
-
Pregnancy: Generally considered safe at recommended doses, but should be used under medical advice.
