Most poison ivy cases go away on their own within 1 to 3 weeks. After about a week, the blisters should begin to dry out and the rash will begin to disappear. Severe cases can last longer, have worse symptoms, and cover more of the body. The skin usually becomes red, itchy, and swollen, and blisters appear.
After a few days, the blisters may crust and begin to peel off. It can take 2 to 3 weeks for a rash people get from poison ivy to heal. Brushing a poison ivy plant can cause bumps and blisters. The rash can spread from one part of the body to another if the oil from the plant stays on the skin.
If the blisters open, do not remove the skin that covers it, as the skin can protect the untreated wound underneath and prevent infections. The skin itches intensely where the rash will appear. Itching can be so severe that it wakes you up from a deep sleep. Soon after the skin starts to itch, the rash appears.
Most people have an itchy, red, and blistering rash. For itching, your healthcare provider may recommend over-the-counter creams, such as calamine lotion. You can also recommend bathing in a bath of baking soda or colloidal oatmeal. You can buy them at your local pharmacy.
Sometimes, your healthcare provider will prescribe a cream or topical medication containing cortisone to take by mouth to treat itching. Oral steroids are commonly used together with oral antihistamines. About 85 percent of Americans are allergic to poison ivy.

If you touch poison ivy with a pair of pants or a shirt and don't wash it after contact, you could develop another rash if you touch clothes.

You can also spread the oil to another person if it comes into contact with clothing that has been in contact with poison ivy. A number of other essential oils, such as calendula, chamomile, and eucalyptus, may be helpful in reducing symptoms of poison ivy rash. The leaves of the poison ivy plant are green in summer, but may turn red, orange, or yellow in spring and fall. The liquid in the ampoules does not contain urushiol, the oil that causes poison ivy or oak rash, so scratching or breaking a blister will not cause the rash to spread.
The rash occurs only where the vegetable oil has been in contact with the skin, so a person with poison ivy cannot spread it through the body by scratching. If the rash comes from poison ivy or a similar plant, your doctor may tell you to take cold showers and use a soothing lotion, such as calamine lotion. However, it is possible to get poison ivy rash if you touch the plant resin that is still on the person or contaminated clothing. More than 4 in 5 people will develop an itchy, red, inflamed skin rash when they come in contact with poison ivy and its urushiol oil.
Calming burn treatment can also relieve itching and inflammation on skin affected by a poison ivy rash.
