  • If you have conditions such as uremia (urea accumulation in the blood), infections, iron or folic acid deficiency, or are being treated with medications that have a suppressive effect on the bone marrow (e.g., chloramphenicol), the effect of vitamin B12 may be reduced.
  • There have been cases of dependence and withdrawal when taking 200 mg of pyridoxine for a month.
  • You should be cautious with sun exposure or avoid it and ultraviolet (UVA) lamp exposure while using this medication, as pyridoxine can cause sun sensitivity (photosensitivity).
