Causes

The causes of itchy skin rashes are as varied as the types of rashes and include viruses, fungal infections, coming into contact with a plant like poison oak, ivy, or sumac, bacteria, allergic reactions to food or medicine, or genetics.

Treatments

Mild itchy skin rashes can be treated with over-the-counter (OTC) medications like hydrocortisone cream and camphor lotion that relieve the itch. Anti-histamine medications like loratadine and diphenhydramine can also help reduce or alleviate symptoms. Severe or contagious rashes (like chickenpox) should be treated by a doctor.

Warnings

Avoid rubbing, scratching, or touching the rash. External contact with the rash can aggravate the condition, thereby making it worse. Contact your doctor immediately if the rash spreads, worsens, or doesn't go away on its own within 1 to 2 days.
