the treatment would be application of steroid cream like mometasone furoate 0.1% once a day for 10 days over the palms and oral antihistaminic tablet like tab. loratidine 5 mg once a day will help you out with the itching. the steroid cream that you are using is slightly milder than the one that i have suggested which will be very effective. in case there is any pus filled lesion, then it is infected, a topical antibiotic cream i.e fucidin will be effective. in case you sweat a lot over your palms and soles that will have to be taken care of as well.
in case you get fissure you need to apply fucidin cream in them
also you could continue vaseline.
