التداخل بين ميتفورمين وفيتامين ب12

Monitor hematological parameters annually and vitamin B 12 at 2 to 3 year intervals and manage any abnormalities.

Vitamin B 12 Deficiency In clinical trials of 29-week duration with metformin HCl tablets, a decrease to subnormal levels of previously normal serum vitamin B 12 levels was observed in approximately 7% of patients.

Such decrease, possibly due to interference with B 12 absorption from the B 12 -intrinsic factor complex, may be associated with anemia but appears to be rapidly reversible with discontinuation of metformin or vitamin B 12 supplementation.

Vitamin B 12 Deficiency : Metformin may lower vitamin B 12 levels.

Certain individuals (those with inadequate vitamin B 12 or calcium intake or absorption) appear to be predisposed to developing subnormal vitamin B 12 levels.
