Yes, my dad is on dexamethazon. He has been taking it since January of this year. However, he is on a pretty low dose right now, taking 2-1-0 pills every day. I just wonder if it eventually goes away. I will tell my mom to try to change detergent as well as per Brainy_chick's suggestion.
It is so wonderfull to know that you come to this site and people are willing to share their experience/advice - one does not feel so alone... and I thank you for that!
