as per yr querry..yr doc has rightly given the medication and advice..i hope she will be fine soon..to me also it seems contact dermatitis
..ask her to avoid..soap, any cosmetics, bleach etc on face and around, avoid itching on the affected area..keep that area clean and she may use along with cortisone
crean she may add neosporin
eye ointment..since u suspect the infection..avoid too much contact with water also..to avoid contamination..
for oral use she may take tab cetrizine
10 mg , 1 tab twice a day or if the problem has decreased then she may take only once a day..at the bed time..sometimes ant allergic medication ..give u drowzy feeling ..so if she feels drowzy..ask her to avoid driving/avoid before office hours..
consult yr doctor after one day.to give the feedback..i think she will be fine soon..take care of her
