Poison Ivy Allergy Rash

Poison ivy can commonly cause a rash known as contact dermatitis. This is an allergic reaction that can occur after contact with the skin, in this case by the poison ivy. There are other plants that can cause such a rash due to the fact that they contain a resin known as urashiol. The rashes of these plants are all similar in appearance, and do not pose a serious health risk.

Symptoms of Poison Ivy Rash

The rash does not occur straight away, rather it takes one or two days after exposure – sometimes several days. It will begin with itchy bumps or blisters which can continue for days. This rash is not contagious, and although it is technically true that animals can carry the resin this is very rarely possible.

Treatment of Poison Ivy Rash

It is much easier to prevent poison ivy rash than to treat it. However, it is a good idea to wash the affected area with soap and water, though this is only effective when done immediately after contact. Many people may not know they have come into contact with poison ivy until it is too late to do this.

When the poison ivy rash has appeared it will clear up on its own within 14 – 21 days. During this time any treatment should be used simply as a way of controlling the itching, which can include antihistamines, cortisone creams (which only help if applied immediately), or compresses with cold water.

If the rash has become severe, causing extensive blistering or affecting areas such as the face, then oral steroids can be used. There are also a number of natural remedies though it is unclear as to whether any of these have much effect.

Identifying Poison Ivy

It can often be hard to identify the poison ivy plant. It is best to keep skin covered when working in an area where exposure is possible.
