Eczema Treatment Care

What lotions could I use to relieve the irritation and reduce the occurrence on eczema? I only get it in a few small places a lot during the summer with the heat and just keep scratching. I currently do not have health insurance so I don’t want to go spend a fortune to get a prescribed lotion. Any tips on good lotion from the drug store or what ingredients to look for in lotions that are helpful?

Is it usually chlorpheniramine or corticosteroid?

I have been under the care of the dermatologist for 2 years and still i suffer really bad. I have been on the strongest drug to reduce the immune system, but i am still bad. If I put loads of moisturiser on it just layers up and makes me itch. The best one so far had been diprobase, but i still come home from work and then itch and scratch like crazy. I want to lead a normal life again. Any Ideas?
