Prolonged B12 deficiency can lead to nerve degeneration and irreversible neurological damage. Methylcobalamin + Nicotinamide + Pyridoxine Hydrochloride is a multivitamin product containing methylcobalamin, nicotinamide, and pyridoxine hydrochloride. Methylcobalamin corrects vitamin B12 deficiency, thereby helping in treating certain anemias and nerve problems. Nicotinamide (vitamin B3) exhibits neuroprotective properties, reduces cholesterol levels and other fatty substances in the blood, and increases good cholesterol. Pyridoxine hydrochloride treats and prevents the deficiency of vitamin B6 and improves the functioning of the nervous and immune systems.                                      SIDE EFFECTS :                                                                                                                                                                   Stomach pain, Diarrhea, Dizziness, Constipation, Injection site reactions (pain, swelling, redness)
