Q: How does someone get a poison ivy rash?

A: Coming into contact with poison ivy via brushing past it with your skin is sufficient to cause a poison ivy rash. Poison vegetation secretes an oil that protects it against bugs and animals. Having this oil rest on your skin causes symptoms because it will eventually seep into your body through your skin’s pores. Heat speeds up the show of symptoms as the pores on the skin are more open. Even during winter, however, you can get poison ivy if you happen to touch the plant during its dormant state. In very rare cases, poison ivy can enter the lungs if the plant is burned and the smoke is inhaled in sufficient quantities.

Q: What are the symptoms like?

A: The first sign of poison ivy rash symptoms comes several hours after first contact with a poison plant. Initially, poison ivy can appear just as a small red spot but over time this spot can spread across the skin, sometimes covering the entire body. Furthermore, this rash is incredibly itchy, almost to an unbearable degree depending on the level of coverage.

Q: Is there any way to prevent symptoms once you have been exposed?

A: Rinsing your skin within an hour of contact with very cold water can help prevent poison ivy symptoms. Cold water not only will wash away the poison ivy oil but will shrink your pores and prevent traces of the oil from entering your body. Using rubbing alcohol on the skin may also help prevent symptoms if you act quickly enough.

Q: What treatments exist for poison ivy?

A: While serious cases of poison ivy rash can be treated by a doctor, many companies produce over the counter products that can help relieve the itch causes by poison ivy. Ask your pharmacist about recommended products in your area and which ones can help you cut down how long your poison ivy rash lasts.

Q: How long does poison ivy last?

A: The common time frame of poison ivy contamination stretches from one week upwards to a month. Typically the amount of time depends on how large the initial contact with the plant was. A small brush may constitute a small amount of time affected. However, reactions to poison ivy differ among people, with some people naturally having immunity to the plant while others are more vulnerable to its oil. How long does poison ivy last also depends on preventative measures taken against it and if any treatment options have been explored.
