Yes there is a shot. It is the same thing just faster acting and the sides are not as bad. I am in the same boat get it bad. I have it right now. I had a shot plus pills and then a shot plus pills again and the symptons are coming back again.
The medication they give you actually does nothing for the poison ivy. When you get it you will have it for a bout 3 weeks wether you take the medication or not. But the medication makes the symptoms go away.
Some other treatments: Cortizone cream, bath in oatmeal, aveno(which is oatmeal), bleach, dish washing detergent, swimming pools, and chlorine.
