Do the leftovers Pimafucort could have irritated my labia?

Yes, it is possible. Pimafucort is a topical medication that combines three active substances: neomycin (an antibiotic), corticosteroid hydrides (in this case, hydrocortisone), and nystatin (an antifungal antibiotic). It is used to treat skin infections, such as bacterial and fungal infections, and inflammation. The skin in the intimate area is sensitive, and Pimafucort, despite its healing effect, can cause irritation such as itching, burning or redness, especially if used for a long time or if it is applied to a large area. The remains of the globule may have irritated your intimate areas, the irritation should subside within a few days.
