Metformin

Reduced serum levels of vitamin B₁₂ occur in up to 30% of people taking long-term anti-diabetic metformin. Deficiency does not develop if dietary intake of vitamin B₁₂ is adequate or prophylactic B₁₂ supplementation is given. If the deficiency is detected, metformin can be continued while the deficiency is corrected with B₁₂ supplements.
