Clinical narrative: once I would stopped my medication (Prednisone) all my Urticaria will come back and I would breakup with Urticaria; Breaking out on hives; Chronic urticaria; Like I have bitten by bugs and down my hamstrings, my buttocks and on my legs; none of the antihistamine weren't doing anything for me and the only thing that helps my Urticaria is the Prednisone; This is a spontaneous received report from contactable reporter. This case is for second dose. A 34-years-old male patient received the second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; Lot Number: EP7533), via an unspecified route of administration on 05Apr2021 (at the age of 34-years-old) as dose 2, single for COVID-19 immunization; and also received prednisone; doxepin hcl (SINEQUAN); montelukast, via an unspecified route of administration from an unspecified date (Batch/Lot number was not reported) to an unspecified date, for an unspecified indication. The patient medical history was not reported. Concomitant medication included finasteride (PROPECIA) taken for alopecia. The patient had no other vaccination before my COVID vaccine. Patient previously received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Lot number: EP753A), via an unspecified route of administration on 15Mar2021 as a single dose for COVID-19 immunization and experienced pruritus, prednisolone for urticaria. Week after, first injection he started waking up itchy when 'I then I thought that I have been bitten by bug and I thought I had bed bugs and since 2nd COVID vaccination on 05Apr2021 I have been breaking out on hives. So the point when I have chronic urticaria. So I have been seeing dermatologist and hopefully this week I will be able to get the problem still there to treat my chronic urticaria probably this condition didn't started happening until after I was vaccinated'. He did a lab test on Monday last week. One thing I wanted to say about my blood work was that he was on a corticosteroid prednisone and had been on and off on prednisone for the past month because of my chronic urticaria. So when had blood work done this past week, was still on the steroid prednisone. The patient was experiencing this problem every single day. So originally thought a, week after first COVID vaccination and he started waking up itchy 'like I had been bitten by bugs and down my hamstrings, my buttocks and on my legs mostly so I thought I had bad bug problem'. The patient went to a dermatologist because it started a break out of hives throughout April after 2nd vaccination. So dermatologist prescribed Prednisone and recommended that he stay on Prednisone until can treat with a allergist. So was on Prednisone for two weeks and 'once I would stopped my medication all my Urticaria will come back and I would breakup with Urticaria it would go away and then we come back and now I urticaria constantly. The patient was taking some amount of Prednisone in the 10 to 20 milligram range; prescribed as much as 10mg, 40mg per day; prescribed as much as 80 mg per day. He was hoping to bad work when I was not on it however the minute I was off Prednisone I break on hives. So I constantly breaking on hives constantly on Prednisone until I can get nowhere'. The patient consulted with allergist and prescribed him with all kinds of different antihistamine and prescribed Montelukast, Doxepin, amlodipine and all kinds of antihistamine in addition to the prednisone in hope you know so he was just having a other reaction for antihistamine to do their job. However 'none of the antihistamine weren't doing anything for me and the only thing that helps my urticaria is the Prednisone. So what I have done is now with my allergist to get special prescription for Xolair which is very expensive drug which will treat chronic urticaria and I'm hopeful that I can get my first treatment with Xolair this week but the more I can get about this and the more I look back into when I started coming out the hives and I can do with my COVID vaccination. So I'm curious now what is the next step, what can be done'. The patient received treatment for events. The outcome of the events was unknown.  Batch/Lot number has been obtained. Further information has been requested.
