How would manage my contact dermatitis with creams?

Very carefully: If you mean over-the-counter creams, don't waste your money. Contact dermatitis nearly always requires the use of prescription-strength creams, and sometimes even they are not strong enough. In those cases, oral or injected medications are required.

Protect: Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot. Use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.
