On December 1st, the Pharmacovigilance Risk Assessment Committee of the European Medicines Agency (EMA) has begun a review of select injectable allergy medications containing methylprednisolone because they may pose risks to those who are allergic to cows' milk.The medications are used to treat severe, quickly developing (acute) allergic reactions and contain the corticosteroid methylprednisolone as an active ingredient. The medications also include lactose, or milk sugar, which can contain traces of cows' milk proteins that could interfere with treatment in the few patients who are highly sensitive to these proteins. According EMA The medicine itself apparently caused an allergic reaction in these patients. In such circumstances, the reaction to the medicine may be mistaken for a worsening of the original condition, leading to additional doses of the medicine being given. The medications under review are for intravenous or intramuscular injection, and they have been available in the European Union for many years under several brand names, including Solu-Medrol (Pfizer). Similar medications without lactose from cows' milk are also available. Have you ever experienced such a situation?
