Frequency and Intensity of Local Reactions in Patients Treated With 4% 5-FU vs 4% 5-FU Associated With an Emollient Cream: a Randomised, Controlled Clinical Trial

Transient local skin reactions with topical Actinic Keratosis treatments such as 5-FluoroUracil (5-FU) often lead to non-adhesion from patients and thus to treatment failure. In regards to 5-FU treatment, these local reactions are related to the pharmacological action of the molecule. The current therapeutic challenge is to reduce the local reactions induced by 5-FU without interfering with its efficacy, in particular by the use of an emollient cream. The aim of the present study is to investigate how the use of an emollient, namely Dexeryl, could improve the local skin reactions occurring during 4 weeks of a 4% 5-FU treatment.
