Rheumatic fever rash generally improves after seven to ten days of treatment, but this is contingent upon completing a full course of antibiotics. This is because the rash is induced by a streptococcal infection. Therefore, to control the infection by streptococcus, the rash will begin to improve. Moreover, if the rash does not subside over time, it may also be considered to strengthen anti-inflammatory treatment with glucocorticoids and anti-allergy treatments to reduce the rash. Additionally, medications like loratadine dispersible tablets and compound glycyrrhizin can be added to help reduce the occurrence of rheumatic fever rash and accelerate its resolution.
