I Don't Make Online Payments To People. Sorry..... But If

I don't make online payments to people. Sorry..... But if you want to know my question, I'm trying to find out the meaning of some words on my Clobetisol Propianate directions, which I don't understand. I have Psoriasis & just discovered that it's not supposed to be used under the arms, & I've been using it for at least 3 years or more! (Bummer!) But what does this mean?
"systemic absorption of Clobatesisol can cause reversible HPA axis suppression ....etc." Then the browser bar cut me off! LOL! What CAN I use uner my arms (armpits). Thanks! - Carol
