Some people have severe allergic reactions to poison ivy, while others are not as affected by contact with the plant. A poison ivy rash is caused by the oils on the leaves of the plant that come in contact with clothing, skin, or items the affected person has touched. Keeping this in mind, any clothing or other items that may have come in contact with poison ivy need to be thoroughly cleaned using soap and water. This should be done to avoid further spreading of the rash.
According to the book "The PDR Family Guide: Encyclopedia of Medical Care", published by Three Rivers Press, poison ivy is identified by a red rash that is blistered and swollen. The rash may seep and form a crusty surface. According to the book, the liquid seeping from the rash does not cause it to spread. Only the oils remaining on the skin will cause additional outbreaks. This is why it is important to wash thoroughly, and avoid touching anything that may have come in contact with poison ivy.
There are oatmeal products available that can be added to a warm bath to help alleviate the itching associated with poison ivy. These products can be very effective. The previously mentioned book also gives information on treating the rash and alleviating the intense itching caused by poison ivy. There are medications available by prescription to reduce swelling and itching. Contact a doctor to find out more about what is available by prescription. It is important not to scratch the affected area because oils left on the skin can cause the rash to spread. Placing cool washcloths over the rash can help relieve the itching, or the patient can soak in a cornstarch bath.
The book also states that the patient should contact their physician if they experience a high fever, soreness of the affected area, pus draining from the rash, scabs that are soft and yellow, or sleeplessness caused by itching.
