what does an allergic reaction to neosporin look like?

Itchy rash typically: The neomycin component of neosporin is a well known and fairly common trigger of allergic contact dermatitis. The rash is itchy, red and occurs where the medication came into contact with the skin. The mechanism is similar to poison ivy type rash. An allergy skin test is available if the diagnosis is in question.
