Allergy to cow's milk protein and reaction to methylprednisolone – case study

Conclusions Test performed with injectable methylprednisolone revealed the presence of nanograms of beta-lactoglobulin in the medication. The presence of food protein, intentionally or by contamination, in medications whose excipients are derived from food, makes the patients with food allergy, susceptible to present adverse reaction to the medication in question, although this occurrence is rare. Therefore patients with CMPA should be advised regarding the use of medications containing milk protein.
