- Sensitization potential: according to studies, sensitization is frequent with topical application, up to 50-60% according to studies. In 25% of the sensitized persons the application time was less than one week.
- Professional sensitizations are rare. In the case of non-occupational exposures a sensitization rate of 1-4% is present. The sensitization rate increases with age. The possibility of sensitization through therapy of occupational eczema should be considered.
- In patients with atopic eczema, sensitization to bufexamac is about 3 times more frequent than in non-atopic patients. This is due to the use of bufexamac in the therapy of atopic eczema.
- In children, Bufexamac is among the "Top Ten" of the most common allergens. Here too, the cause can be assumed to be the frequent use of bufexamac in the therapy of atopic eczema.
- Risk factors of a Bufexamac sensitization include further type IV sensitizations, anogenital localization, atopic eczema, eczema of the legs.
- In the meantime, the EMA is demanding that the Bufexamac-containing topicals be withdrawn from the market.
