The caller stated her son received the first dose of the vaccine on 04Feb2021 and is scheduled for his second dose 25Feb2021. About 14 hours after the vaccine he developed lip swelling and was treated with Benadryl. The next day his lip was swelling again and he had to go to the emergency room and get Benadryl and a Solumedrol injection and the lip swelling went down.  At first the thought it was his losartan because 2 and half hours after he took it his lips started swelling. They took him off of his Olmesartan 20mg. They gave him amlodipine instead, because they thought that the Olmesartan could have caused it, but the ER staff also thought it could be because of the shot and the blood pressure medication, or just the shot. The ER said it was his blood pressure medication but he has taken it for 3 years with no issues. The caller said that her son has been on the Olmesartan 20mg for 3 years though. She said that he takes it with Hydrochlorothiazide 25mg. She said that he has never had an allergic reaction to anything before. He did not eat anything that could have caused it. The caller said that her son did not have any wheezing, breathing, or swallowing issues. It was just the lips that were swollen and he had it no place else on his body. She stated he has never had any reaction to anything except when he was tiny and young he has a swollen foot when he stepped on honey bees. He has severe social anxiety and agoraphobia so he is basically a hypochondriac.  She stated he ended up getting a slight case of covid (did not state when) and she doesn't want him to get it more, especially since they have the variant there in (State name). She said it would be an act of God that this happens though because no one can go anywhere right now because of the snow and it will probably be another week before they can go anywhere. The healthcare provider said they probably wouldn't give him the second dose, but not that he shouldn't have it. On an unspecified date in Feb2021, the patient experienced sore arm.
