You can get an Aveeno Oatmeal Soak to bathe in. I have been using this at night this week since I had an unavoidable contact with a lot of mosquitoes this past weekend and I am very allergic to them (more than most people; I actually get hives and the bites turn into dark red welts that last for days). Children's Benadryl also helps me with mosquito bites, and I saw in the list I copied and pasted below that it is recommended for poison ivy, too.
Change your sheets on your bed. You may have gotten some of the oils from the ivy in the sheets (depending on if you showered and washed the ivy rash before going to bed or not), so you'll just keep giving yourself poison ivy if the oils are there.
Clean anything that may have been exposed to the poison ivy (such as your shoes or tools), with rubbing alcohol and water (to get rid of the oils).
I found this list of medicines online:
