But for last 1 year she suffered from blodd pressure & from last 10 months she sufferred from diabetics.but for last 2 months her psoriasis agravated.her entire body filled with red spots with small pus aound spots. First doctor treated her as drug reaction by giving an antibiotic named lizoforce 600 and then an steroid named dexona.she was tottaly cured after a few days again she relapse with the same with urine infection and now doctor called it as pulsutar psoriasis. a doctor prescribed her methotrexate 7.5 once a week with acitretin 25 mg twice a day. But i found in inter net that both can not be taken simulteneously and acetretin should be taken in small dose like 10mg once a day. so i contacted another doctor, he prescirbed methtrexate 7.5 once a week with sysfol thrice a week and an antibiotic etc. but it found no relief..plz advice some solution..can she bath in sea ( dead sea salt, epsom salt) to get relief ? or what mediene she should take.we stay in india.
