Which food allergy contraindicates the use of fluticasone?

Fluticasone is a corticosteroid commonly used in the treatment of various conditions, including asthma and allergic rhinitis. One of the concerns when prescribing medications is the potential for allergic reactions, especially in patients with existing food allergies. In this case, the correct choice is milk allergy.

Individuals with a milk allergy are at risk of an allergic reaction to products that may contain milk proteins, which can sometimes be present in medications, including intranasal or inhaled corticosteroids. Fluticasone may be formulated with lactose, which is derived from milk, and can trigger a reaction in those who are allergic to milk. Therefore, for patients with a known milk allergy, fluticasone may not be suitable as it could put them at risk for adverse reactions.

In contrast, while eggs, nuts, and soy can also be associated with allergies, they are not typically relevant to the contraindications for fluticasone use. Fluticasone formulations generally do not contain any derivatives from these allergens. Thus, knowing the specific food allergies and their compatibility with medication ingredients is crucial in ensuring patient safety when prescribing treatments like fluticasone.
