Elevated WBC - due to steroids.  Critical care management as above.   Zyrtec 20 mg bid Continue benadryl 50 mg q 6-8 hr as needed basis only Albuterol prn sob Prednisone 20 mg every day x 3 days, then 10 mg every day x 3 days Side effects discussed with patient  rx of epi pen written for patient. Its uses discussed in detail.  Referral to allergy dept - for follow up and to discuss about second dose of covid vaccine Call 911 if symptoms develop again or worse.  er precautions discussed. Follow up Primary care physician in 24-48 hr. Patient understood all instructions.  5/5 PCP f/u Patient presents for follow up of allergic reaction. Suspect this reaction may have been due ot something she consumed the night before when eating food out rather than the Pfizer vaccine which she had received 8 days prior to the reaction starting. However, she does have appointment with allergy to further discuss this and give formal recommendation on whether she should receive second dose of vaccine. She will continue zyrtec twice a day along with benadryl PRN. Albuterol inhaler sent to different pharmacy along with epi pen. Advised her to continue 20mg prednisone for now untli Friday because her rash did show up in a new place on the back, and she still has some facial swelling. I would be concerned for her reducing the dose before her symptoms start to show improvement. Follow up visit to be scheduled with me on Friday in 2 days, she will inform us if any worsening symptoms. No current anaphylactic symptoms.  5/6 Allergy consult Do not suspect food allergy trigger.   Postpone 2nd covid vaccine dose 2 weeks.  Monitor rash, if resolves in the next week or so, proceed with the second dose.  Stay on zyrtec (cetrizine) now, continue until rash resolved and/or if get 2nd dose, continue for a week after 2nd dose.  If do not get second dose or if similar rash after 2nd dose, requiring prednisone, contact me check antibody titer about a month after finish prednisone.   Continue to avoid tree nuts.    5/7 PCP F/u Patient presents for follow up of allergic reaction that presented one week after receiving Pfizer vaccine. She saw allergist who suspects this is related to vaccine rather than dietary trigger (she has tree nut allergy).   Patient states that the rash in her arms and legs are better. The swelling and puffiness are improved. Just a rash on the neck and back and feet remain that are improving. She is on her last 20mg prednisone then will taper this weekend. Still taking zyrtec twice a day and benadryl every 6 hours as needed for itching.    No further f/u Pt was vaccinated w/ second dose on 5/23 with no indication of reaction in pt chart.
