I have had psoriasis for 15 yrs and psoriatic arthritis for 5. After having a major flare up of psoriatic arthritis where my tendons and major joints swelled.My doctor finally decided to prescribe me something for the swelling after 4 months of not being able to walk most days. I first started with Sulfasalasine (500mg daily for 7 days, 500mg twice daily for 7 days, 500mg three times daily for 7 days, and 1000mg twice daily for 7 days). After a month my psoriasis started to flare and it looked as if i was having a rash so it was discontinued. A week later i received a prescription for Plaquenil (200mg x2 for 14 days) and Prednisone (4x5mg) in the mail. It was a two week trial of plaquenil, and with the prednisone i was to decrease by half a pill every three days. By the end of the two weeks of plaquenil i was noticing a red blotchy rash on my chest. I contacted my doctor. 3 days later the rash had gone from my chest to my neck to my cheeks. By the 4th day i had swelling around my eyes and they were also red and blotchy, my hands were also swollen to the point where i couldnt bend them and I was having a fever and night sweats. My doctor finally contacted me on the fifth day after stopping the plaquenil, and told me to discontinue it. I went to the hospital on that day and told them i thought i was having a allergic reaction to plaquenil, they stood five feet away looked at me and said ok just keep taking the prednisone at 20 mgs for a few days. They didnt want to get involved due to the fact that i had psoriasis. But also failed to mention to me that it could be the prednisone causing this reaction also. The next day i saw my dermatologist, she prescribed 1% hydrocorisone cream which helped with some of the dryness and pealing skin. The next day when i woke up i couldnt open my eyes, i was having shortness of breath ( im not sure if it was the panic from not being able to see) my throat felt as if i had strep throat,and the roof of my mouth felt as if i had burned it. My skin looked like a huge sunburn, the parts where i had psoriasis were very red,raw,and pealing excessively. I was admitted to the hospital for four hrs where they gave me a IV of benedryl and a steriod.My skin was so swollen they could just barely find a vein to put the IV in. After 50mg of benedry they realeased me and told me to keep taking 50mg every 4-6 hrs and they prescribed me 50mg of prednisone for 7 days. By the next day the swelling had gone down by 30% in my face, but i still looked like i had been in a fight, the pressure around my eyes was so much that i had to sleep sitting up. Of course i wasnt really able to sleep with the fear that if i closed them i wouldnt be able to open them again. They also leaking white stuff. My skin was pealing in very large sections. I was bathing in a luke warm bath with oil, which would help with the pealing of my skin but then when i came out i would be freezing cold. I would get hot flashes and then instantly cold 5 minutes later. I felt like i running a fever but my temperature was normal. Two days later the swelling was gone in my face, but my legs, ankles and feet were abnormally swollen. My skin was still pealing and constantly itchy. My skin tone was all pink it was no longer red and blotchy, but after i would shower or bath my legs would have dark purple and blue spots on them that looked like bruises. I was unable to sleep for more then two hours straight, i would wake up feeling as if i was on fire. It took another six days for the swelling to go down fully in my legs, ankles and feet. After taking 50mg of prednisone for 7 days I am taking 45mg for 7 days then decreasing by 1 pill every week. After taking 45 mg for 3 days my skin looks as if its a big rash, it feels grainy and tight. Its no longer pealing except for on my feet. Im told i look as if i have a bad sunburn, my face is red and tight to the point where the skin around my eyes doesnt even stretch when i open them widely.The sides of my mouth keep cracking when i try to open it fully. I look as if i have really dry skin constantly, it is a fine dusty flakeness. I bathe in moisturizing bath oil but it doesnt even go past the first layer of skin it seems, and i moisturize with keri lotion 3 or 4 times a day but it doesnt seem to matter how much i do it 15 minutes later im just as dry.My skin is sensitive to light and feels like its on fire when exposed to any amount of sunlight. The skin around my armpits and breasts or anywhere that the skin has to strecth is red and sore. I still get hot flashes but most the time i am freezing cold. The skin on my hands is wrinkley and i have no sense of touch almost. My nails were so brittle they had to be cut all the way back. I have numbing of the tongue, i cant even taste food anymore. I have dry mouth, and i feel as if im dehydrated constantly, i can drink bottle after bottle of water and still feel thirsty. I feel really hungry sometimes or not at all at others. Some days it feels like I IBS and then other days it can be fine. I am losing my hair. The roof of my mouth still feels as if ive burned it on something hot. My legs still look purple at times when im standing, and especially after being in the shower or bath. I am taking 1mg of both folic acid and zinc which my rheumatologist suggest to help slow the reproduction of my skin cells. I have blurred vision 90% of the time, and sometimes i see halos around letters. My mood swings are all over the place, some days i feel like just crawling into a ball and not moving, mostly because its too painful to move around and also because i hate how I look. And other days i just feel nothing at all. Im not exactly sure if when i was the 50mg of prednisone i was happy because of the drug or if i was happy in general because i realized what i could have lost. Not being able to see for 15 minutes really put things into perspective. Im not sure how much worse it can get? I thought the swelling of my eyes was the worst part but from what i hear it can get much worse coming down off of prednisone. I was wondering if anyone else with psoriasis may have experienced any of these side effects while on prednisone? and roughly how long it took for them to go away.
