Hi, thanks for using healthcare magic
She may want to use a mild topical steroid
for a short period of time to treat the flare up , along with the ketoconazole
. After using the topical steroid for a few days (no more than 5) then she can stop because though used for flares they can hasten recurrences, she can restart the tacrolimus at this time and continue it with the ketoconazole.
She may want to consider visiting her doctor for a check up.
Hope this helps
