Hello, You are probably experiencing some side effect of one or more of the drugs prescribed by the dermatologist. If by dox caps you mean doxycycline then you should know that one of it side effects is unexplained rash ( you should stop taking it and contact the dermatologist). haloderm lotion is natural body lotion that might not be the one responsible for the increasing rashes ( but since we are not sure whether you can react to the lotion: combination of vitamin E and aloe vera plus other agents, you can stop it for now). Hyzine being an antihistamine would not normally cause any more rashes but in very very rare situations some people can manifest allergy (skin rashes and others). Oxidon plus being an antioxidant classified as vitamins/minerals would not have rashes as side effects except allergy. octamop is a drug used for the treatment of vitiligo and probably the dermatologist diagnosed some vitiligo lesions and decided to include that in your treatment. He is better placed to make the right judgement for your manifestation. So my guess is, the dox caps are responsible for the increased rashes and should be stopped. I do not know which regimen you were on before you saw the dermatologist, but the following are regimens recommended by the National Psoriasis foundation: - calcipotriene cream - calcipotriene and betamethasone dipropionate combination cream - Topical steroids - UV light - Calcium and vitamin D supplementation could also be useful if chronic hypocalcemia is the cause of your psoriasis ( generally there would have been manifestations in other areas of the body order than the scalp). Hope this helps
