What is the best way to treat dyshidrosis eczema over the counter?

Nothing great OTC: Dyshidrosis affects hands and feet where the skin is quite thick and tough. Hard for medications even to get through to the live layers of skin. Hydrocortisone 1% ointment is probably the best OTC there is, and if you wear cotton gloves over a generous application that may help improve penetration but prescription medication is best.

DYSHIDROSIS: DYSHIDROSIS IS MANIFESTED BY SMALL, FLUID-FILLED BLISTERS APPEARING OVER THE FINGERS, THE TOES, THE PALMS, AND THE FEET. THEY CAN BE VERY ITCHY. THEY CAN APPEAR OFTEN IN PEOPLE WITH ALLERGIES SUCH AS HAY FEVER, PEOPLE WHO WORK WITH CEMENT, AND IS OFTEN AGGRAVATED BY STRESS. THERE ARE NO OVER THE COUNTER REMEDIES. A DERMATOLOGIST IS THE DOCTOR YOU SHOULD SEE. BEST LUCK!

Not easy: Are the hands the major issues? If so. Avoid antibacterial or scented soap. Use a good moisturizer as often as possible after hand washing. Avoid irritants or solvents- wear non-tatex gloves as precautions. There is no great solution however OTC or Rx.
