To prevent contact dermatitis, a person can take the following steps:
Once an individual is aware of allergens that trigger their contact dermatitis, they should take steps to avoid the trigger. For example, people sensitive to PPD can use temporary hair rinses or dyes that are PPD-free. A person sensitive to neomycin ointment should use antibiotic ointments that don't contain that medication.
If contact dermatitis is not treated effectively, the individual may have almost constant outbreaks of the allergic reaction. Skin may become very irritated, with skin thickening and changes in color. Secondary infections can occur.
Contact dermatitis is not contagious and poses no risk to others.
