Can I Use Mometasone Furoate Cream On A Rash Around My Vagina Caused By Eczema?

Hi I wore some of my boyfriends shorts to sleep that were freshly cleaned about a week ago. When I woke up I have a rash kind of like eczema around my vagina. I have been diagnosed with eczema a whole ago and have mometasone fur oats cream 0.1% and it has really helped with my eczema in the past. Could I use it on the areas that itch?
