Warnings and Precautions

Consult your doctor or pharmacist before starting to take Bester Complex.

  • 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).

  • Interference with analytical tests: If you are going to undergo any diagnostic test (including blood tests, urine tests, skin tests using allergens, etc.), inform your doctor that you are taking this medication, as it may alter the results. In some determinations of urobilinogen, theophylline, and uric acid, false results may be produced.
