[Treatment response in vitamin B12 deficiency depends on the chosen vitamin B12 preparation].

Abstract

In Denmark, patients with vitamin B12 deficiency are usually treated for life with either Betolvex or Vibeden given as injections every third month. This case report describes a patient who received injections with vitamin B12 prescribed in Germany. The drug prescribed was not available in Denmark; hence the treatment was unsuccessful after the patient returned to Denmark. This led to extensive diagnosing before the cause for the inadequate treatment was found. It illustrates that different vitamin B12 drugs may result in different treatment outcomes, and that caution should be taken when treating patients with vitamin B12 drugs from other countries.
