Matters needing attention

1. Leber's disease

Disease is a family hereditary retrobulbar optic neuritis and smoking amblyopia. Serum vitamin B 12 is abnormally increased. If treated with vitamin B 12, optic atrophy can be rapidly aggravated, but hydroxycobalamin is beneficial.

2. If gout patients use this product, attention should be paid to it, because the accelerated degradation of nucleic acid and the increase of serum uric acid can induce gout attacks.

3. Patients with nervous system damage should not use vitamin B 12 before the diagnosis is clear, so as not to cover up the clinical manifestations of subacute combined degeneration.

4. Vitamin B 12 deficiency may be accompanied by folic acid deficiency. If treated with vitamin B 12, the hemogram can be improved, but the clinical manifestations of folic acid deficiency can be covered up. Folic acid should be supplemented to these patients at the same time to achieve better curative effect.

5. Vitamin B 12 is used to treat megaloblastic anemia. In the first 48 hours, it is advisable to check the blood potassium. In order to find out the possible severe hypokalemia in time.

6. Antibiotics will affect the determination of vitamin B 12 in serum and red blood cells, especially the application of microbiological examination methods will produce false low values. Attention should be paid to the follow-up determination of serum vitamin B 12 before and after treatment.
