While contact dermatitis normally clears up in a few weeks, extreme cases can fester. There is a chance for infection, especially if the rash forms blisters or open sores.

Secondary bacterial skin infections can cause serious health problems if left untreated. Usually, these infections can be treated with standard antibiotics, whether orally or in ointment form.

Generally, if contact dermatitis is well cared for, there are rarely few complications associated with it.
