Thanks for writing back.
As finger webs and genitals are involved and the rash
has persisted for more than a month, I would advise that scabies
should be considered as a strong possibility.
Had he visited my clinic, I would have prescribed Permethrin 5 percent cream application all over the body neck downwards. This has to be applied just once overnight and the whole tube should be used at one go, so that whole body area is covered properly and then in morning a proper bath should be taken.
is an effective but a sedating antihistamine. So he may use levocetrizine twice daily till itching persists. Also once permethrin has been applied, from next day onwards, he may continue using triamcinolone
cream twice in a day over the itchy rashes. Hopefully in a week or two, his itching and lesions would resolve.
Hope this helped.
