You’re Allergic to the Oil from these Plants
Poison ivy secretes an oil known as urushiol. When a person comes in contact with the oils from these plants this causes an allergic reaction. You may notice a rash that forms in a straight line (as if you brushed against a poison ivy leaf). If you suspect that you’ve come into contact with poison ivy, sumac, or oak, it’s important to wash your clothes immediately and to take a shower to prevent the oils from spreading further.
You Can Usually Treat It Yourself
While the rash can be unpleasant, symptoms should go away within 2-3 weeks. Since the rash can be quite itchy and uncomfortable, here are some ways to ease your symptoms:
- Take cool, oatmeal baths to alleviate inflammation and itching
- Apply calamine lotions to the skin to temporarily alleviate itching
- Steroid creams (aka: cortisone cream) may also alleviate redness and inflammation
- Apply cold compresses to the area when symptoms flare-up
- Whatever you do, do not scratch your rash (this can lead to an infection)
Some people have severe allergic reactions when they come into contact with poison ivy, sumac, or oak. You must call your dermatologist as soon as possible if:
- Pus develops on the rash
- You also have a fever over 100 F
- You experience severe itching
- The rash keeps spreading
- You aren’t sure whether the rash is caused by poison ivy, oak, or sumac
- The rash spreads to the mouth or the eyes
- Symptoms don’t improve within a week
Have you heard of Toxicodendron radicans? No? Well, you have likely heard of their colloquial name—poison ivy. Sporting leaves filled with Urushiol, an oily resin that can cause a painful rash when in contact with human skin, poison ivy can cause a number of painfully uncomfortable symptoms.
Read on to learn the symptoms of poison ivy exposure, how to treat its symptoms, and whether those symptoms warrant a trip to your local dermatologist.
Rash Symptoms
Poison ivy rashes often show up right after exposure to the plant leaves, although they do sometimes spring up a couple days afterward, as well. Symptoms of the rash include:
- Red streaks and patches on the skin
- The emergence of hives, blisters, and red bumps
- General swelling
- Acute itching
Treatment Options
Once you have discovered the rash, there are some initial steps that you can take to relieve your symptoms. These include:
- Immediately run cool water over your skin at the first sight of rash
- Use over-the-counter cortisone and calamine creams to relieve itching
- Take an oral antihistamine (e.g. Benadry) to reduce itching and inflammation
After 1 to 3 weeks, the rash should dissipate on its own, without the requirement for medical care. However, there are some scenarios in which you should seek out the attention of your local dermatologist. For instance, call a doctor if you experience:
- Pus emitting from the rash
- A general spreading of the rash
- A failure of the rash to clear up after a couple weeks
In other scenarios, emergency care may prove necessary. Call 911 if you experience:
- Trouble breathing or a swelling of the throat
- Extreme swelling, especially around the eyes
- A spreading of the rash to the mouth, eyes, or genitals
