Frequency not reported: Allergic or hypersensitivity reactions; anaphylactoid reaction, anaphylaxis, angioedema, bronchospasm

A European review describes cases of allergic reactions, including bronchospasm and anaphylaxis, in patients allergic to cows milk proteins receiving injectable methylprednisolone products containing lactose of bovine origin. In most cases, the patients were younger than 12 years old and had childhood asthma. In some cases, the reaction was mistaken as lack of efficacy, and additional doses of were give with subsequent worsening of the patients condition. The European Union has recommended lactose-containing methylprednisolone products be reformulated to remove any trace of milk proteins by 2019.
