Hi, Psoriasis at times can prove to be a bit refractory to treatment. As you have mentioned that your lipid profile is deranged, so obviously acitretin needs to be withheld or stopped. Sorvate c contains clobetasol (a potent steroid) and calcitriol(a vit d derivative). Both of them are quite effective in treating psoriatic lesions and can be used for a prolonged period provided you do not develop any itching, redness or irritation with the medicine . Also use a good emollient to keep your hands and feet well moisturised. Take care.
