Objective: to observe the effect of fluticasone propionate cream combined with Hedan tablets on seborrheic dermatitis of head and face. Methods: the research object is the head dermatitis patients admitted to the Jiangbei Hospital of Southwest Hospital. The total number of patients is 120. The period from January 2020 to December 2020 is taken as the research period. The patients are divided into the control group and the observation group. The number of the control group is 60. The patients will be treated with fluticasone propionate cream, while the patients in the observation group will be treated with fluticasone propionate cream combined with Hedan tablet. Finally, the two groups were compared after using different methods, as well as the changes in the first week and the second week after that, and the relapse rate and adverse reaction rate after the fourth week and the third month after continuing the medication. Results: the symptom changes and healing effects of the two groups after 7 days and 14 days of treatment were compared, and then according to the comparison of relapse rate and side effects observed at 4 weeks and 3 months, it can be concluded that the control group was significantly better than the observation group in terms of erythema, pruritus, desquamation and lesion area (p > 0.05), and the observation group was shorter than the control group in terms of overall average effective time (p > 0.05). As far as the known relapse rate scores after 3 months of treatment are concerned, the scores in the control group are significantly higher than those in the observation group (p < 0.05), but there is no significant difference in the incidence of adverse reactions (p > 0.05). In addition, during the random examination of all patients, the relapse rate of patients with the disease observed within three months after taking the product was lower than that of the control group, and P < 0.05. Discussion: Fluticasone Propionate Cream has the following characteristics in the treatment of seborrheic dermatitis on the head and face: fast insertion, good healing effect and few side effects. When used in combination with Hedan tablets, it can significantly reduce the incidence of seborrheic dermatitis. 展开更多
