Have you ever come home from a walk in the woods, a garden, or an unfamiliar plant and found yourself with red, itchy, and blister-like bumps on your skin? It could be an allergic reaction to the sap (oil) of a plant like Poison Ivy, Oak, or Sumac, which are common in Western countries. Although these plants are not very common in our country, you may encounter this when traveling abroad or in some forested areas. Therefore, it is very important to be aware of this. Don't worry, this is usually not serious. It usually gets better on its own within one to three weeks. Let's see what you can do at home for this condition and when you should see a doctor.
What should you do first?
Imagine that you have been bitten by a plant like this. The first and most important thing to do is to wash the area of skin you think you may have been exposed to with soap and warm water. Do this within 10 to 15 minutes if possible. This will help remove the urushiol oil from the plant before it can be absorbed into the skin, greatly reducing the risk of an allergic reaction.
Also, immediately remove any clothes, shoes, and socks you were wearing at the time and wash them thoroughly separately. If the oil remains on your clothes, it can transfer to your skin or the skin of someone else in the house.
What remedies can be done at home?
Although these sores and blisters will heal on their own within a few weeks, the itching and discomfort during that time can be quite unbearable. So there are a few simple things you can do at home to help reduce the discomfort.
Itching and oozing fluid from blisters
If the blisters are oozing a little fluid, there are some ointments you can buy at the pharmacy to control it. These will also reduce the itching a little.
| Lotion/Cream Type | Action |
|---|---|
| Calamine Lotion | Cools the skin, reducing itching and discomfort. |
| Aluminum Acetate (Burow's solution) | Helps dry out blisters and control oozing fluid. |
| Colloidal Oatmeal (special oats powder) | Itching can be reduced by mixing it with water and applying it, or by adding it to bath water and soaking in a bucket. |
| Baking Soda | Mixing it with a little water and making a paste and applying it can provide relief from itching. |
Steroid cream and antihistamine tablets
You can get relief by using a steroid cream for the first few days after the rash appears. However, creams like 1% Hydrocortisone that you can buy at the pharmacy may not be enough for such a severe allergy. Therefore, it is best to show your doctor and use a stronger steroid cream that he or she prescribes.
Some people use antihistamines to relieve itching. However, these do not completely stop the itching. However, taking a drowsy antihistamine, such as Diphenhydramine (Benadryl) , at night can help reduce the itch and help you sleep better. Talk to your doctor about this as well.
Other simple methods
- Soaking in cool water: Soaking in a bucket of cool water with a little oatmeal-based bath product for a while provides great relief to the skin.
- Cool compress: Soak a clean cloth in ice water, wring it out well, and place it on the affected area for 15-30 minutes. Do this several times a day.
Don't mention these things!
Some things you do to get relief can actually make the situation worse. So avoid these mistakes.
No matter how much you scratch, avoid picking or scratching the blisters completely. Bacteria from your nails and hands can enter the broken blisters and cause a serious skin infection.
Also, do not use the following creams. These may worsen the allergy.
| Types of cosmetics to avoid | Reason |
|---|---|
| Antihistamine cream or lotion | These can further aggravate skin allergies. |
| Creams containing numbing agents such as benzocaine | These can also cause another skin allergy. |
| Antibiotic cream containing Neomycin or Bacitracin | Applying these without medical advice can cause a skin reaction and worsen the condition. |
When do you need to see a doctor?
Although this condition can often be managed at home, it can be more severe in some people. If you have any of the symptoms below, it is important to see a doctor right away.
- Fever: If the body temperature is higher than 100 Fahrenheit (37.8°C).
- Pus: If pus is visible on the wound, this is a sign of a bacterial infection.
- Yellow crusts: If soft, yellow crusts have formed on the skin.
- Severe itching: If the itching is getting worse or is so severe that it wakes you up at night.
- Spread: If the rash spreads to sensitive areas such as the eyes, mouth, or genitals.
- Not healing: If the wound does not appear to be improving after two to three weeks.
In this case, your doctor may prescribe oral corticosteroid pills (such as Prednisone) or a stronger steroid cream. If the blisters are infected, they may also prescribe oral antibiotics.
When to seek emergency treatment (ETU)
In rare cases, these plants can cause a severe, even life-threatening allergic reaction. If you have these symptoms, you should go to the nearest hospital emergency room (ETU) without delay .
- If you have difficulty breathing .
- If you have difficulty swallowing food and drink .
- If an eyelid is swollen and the eye is closed .
- If the lesions are widespread on the face or genital areas .
- If your whole body is itching unbearably and nothing provides relief.
These are symptoms of a severe allergy, so it is essential to seek immediate medical attention.
