I Got What I Think Was A Bad Case Of

I got what I think was a bad case of psoriasis on my eyebrows, and forehead with a touch of it on the side of my nose and on my ears. The spots just kept getting progressively worse and I was using a triple antibiotic cream; then, I tried a hydrocortisone cream; then, a psoriasis cream and nothing seemed to really work. I was still getting a lot of scaling, flaking, redness, itch, and I just looked awful. Then, a friend of mine offered me his Taro Clobetasol Propionate cream 0.05% and it worked almost overnight. I am now on vacation with my husband and don't have any of my own. What can I buy OTC to substitute for this? I won't be home for another 2 weeks and I am not even sure if I can afford the cream for prescription.
