The over-the-counter stuff did little for me. Technu may have helped me to not get it but is hard to confirm. I take it to CA every time now because poison oak is hell on me. I had it for weeks and my feet swelled so big I could barely put on shoes and my ankles were seeping so much fluid that the cuffs of my pants were one big crusty scab.
Calamine, benedril, bleach baths, etc. did nothing. I eventually got a perscription for Vanos, a steroid cream. Much better in a matter of hours and gone in less than two days. The tube I bought was over $100 with insurance! $300 without! The dermatologists had some small sample tubes that would probably been enough, you don't need very much.
