Itchy rash that the doctor says is inhalent

I'm not sure what you mean when you say your doctor says it's an inhalent....? But yes, otc creams and lotions can work very well such as Aveeno Oatmeal bath and lotions as well as the Benedryl line of products. Oral Benedryl (liquid or capsule) can make you super sleepy so be careful if you take this. I was covered in chigger bites about 2 years ago and I used the Benedryl spray which did wonders for the intense itch from the bug bites.
