How to Get Rid of an Allergic Reaction Rash on the Crease of My Arm

• 1

  Take 25 mg of Benadryl when you first start developing a rash, and every 6 hours thereafter, not to exceed 100 mg per day, according to the Food and Drug Administration. Benadryl stops the effects of histamine in your body which causes rashes and itching.

• 2

  Apply an ample amount of hydrocortisone cream directly to the allergic reaction rash. This will help to alleviate your symptoms and clear up the rash.

• 3

  Apply an ample amount of calamine lotion to the rash once the hydrocortisone cream has dried. This will help to stop itching and will heal the rash.

• 4

  Avoid the item that caused your allergic reaction rash. Often, people develop these rashes after switching laundry detergents, soaps, or lotions.

• 5

  If the allergic reaction rash does not resolve in 1 to 2 days, visit your physician. He may give you prescription strength anti-histamines and lotions to apply to the affected area. He may also elect to perform allergy testing to determine what you are allergic to to prevent further episodes.
