  • using beauty products, soaps, and laundry detergent

  • touching poisonous plants, such as poison oak, poison ivy, or poison sumac

Taking medications may also cause rashes which can form as a result of either an allergic reaction to the medication or a side effect of the medication. Photosensitivity to the medication can also cause rashes.

Treatment for a Rash:

As most of the rashes last a while and get better on their own, treatment of symptoms like itchy and/or dry skin is often not required. You can watch them for a few days to see whether the condition gets milder and goes away. Most rashes are not dangerous and can be taken care at home.
To help ease discomfort and speed up the healing process, you can try the following things:

  • Use warm water instead of hot water for washing your skin and hair.
  • Use mild, gentle cleansers instead of scented bar soaps.
  • Avoid scratching the rash because doing so can make it worse and could lead to infection.
  • Pat the rash dry instead of rubbing it.
  • Avoid covering it with clothing if possible. Allow it to breathe.
  • Stop using new cosmetics or lotions because they may have triggered the rash.
  • Apply unscented moisturizing lotion to areas affected by eczema.
  • Wash your hair and scalp regularly with dandruff shampoo if you have dandruff along with a rash. Medicated dandruff shampoo is commonly available at drugstores. Consult your doctor for a stronger types if you need them.
  • Apply an over-the-counter hydrocortisone cream to the affected area if the rash is very itchy and causing discomfort. Calamine lotion can also help relieve rashes from chickenpox, poison ivy, or poison oak.
  • Take an oatmeal bath. This can soothe the itchiness associated with rashes from eczema or psoriasis.

Over-the-counter medications:

  • Anti-itch creams containing 1% of hydrocortisone can be effective for relieving itching
  • Oral antihistamines like diphenhydramine and hydroxyzine can be helpful in controlling the itching.
  • Moisturizing lotions
  • Fungal infections are best treated with topical antifungal medications that contain clotrimazole, miconazole, or terbinafine.
  • Acetaminophen or ibuprofen can be used in moderation for mild pain associated with the rash. But you may not be able to take them if you have liver or kidney disease or a history of stomach ulcers.

Consult your doctor before you start taking these drugs, and avoid taking them for an extended period because they of potential side effects. If the above things does not help and the rash persists or becomes more widespread, a consultation with a general physician or dermatologist is advisable.


Smallpox vaccine can be given as a prevention for some rashes. As patients with atopic dermatitis are more susceptible to having the virus spread on their skin, which can lead to a serious, even life-threatening condition called eczema vaccinatum, they should not be vaccinated against smallpox.
Visit your doctor immediately if you experience a rash along with any of the following symptoms:

  • increasing pain or discoloration in the rash area
  • fever of 100.4°F (38°C) or higher
  • tightness or itchiness in the throat
  • difficulty breathing
  • swelling of the face or extremities
  • severe head or neck pain
  • repeated vomiting or diarrhea

  • a fever slightly above 100.4°F (38°C)
  • joint pain
  • a sore throat
  • red streaks or tender areas near the rash
