How long until a poison ivy rash heals and goes away?

It takes a good two weeks for a poison ivy rash to heal and go away, without the benefit of oral medication such as prednisone.

It should pretty much be gone in about ten days. You don't want it to spread anymore so don't scratch it. Keep the area dry and clean. There are lotions on the market that will give relief to the itching. One home remedy is to make a paste of ashes(wood ash) and apply.
