I have had psoriasis for 27 years I went to GP and with an itch and he did not examine me but said it was possibly infected and prescribed ciprofloxacin 500mg which has black box warning. I have extreme sensitivity to medication and not sure if he reviewed my case file. I noticed that while on med my skin went purplish/red and felt like it was burning. I went back again itching very badly with rash on my stomach and my scalp was purple. He represcribed ciprofloxacin 5 day course again with follow up of tetrasyl. I started burning once again and it turned purplish. I assumed it was bacterial infection and carried on with course and then commenced tetraysl. All my skin burnt off I was blistered, my toes came out of skin. Emergency Doc said it was AGEP reaction and so did pharmacist. Dr left me like this and by 3 weeks later ended up in hospital on a drip with obs not good. I was swollen, and it looked like it had all joined up from original dusky purple spots, saggy skin to one big purple, reddish inflammation. They could not find any infection at hospital. Was in patient for 5 weeks. And now half my hair has fallen out and I react to all steroids. The hospital has said it was prop psoriasis flare up due to stress and not a drug reaction. I was not stressed. I know this is not true I have never suffered with psoriasis like this. Can they confirm it is a drug reaction by patch test or blood test. My gums are inflamed also. I have asked them if it could be lupus from tetrasyl bu the they said unlikely. I am very distressed. The gp in question did not examine me properly when he prescribed cipro also he did not refer me urgently when I told him I was burnt as he should have in event that it was steven Johnston disease. Can you advise what I can do as I know it was drug reaction.
