Her lips swelled, her throat was super tight, and her tongue swelled. She ended up in the ER, and they put her on steroids. She was supposed to get her second shot "today", but now she will get it in 2 weeks. She needed to know if this was a common reaction. The reaction happened on Saturday 08May2021 the day before Mother's Day. She took Benadryl a couple of times on 09May2021. Around noon 09May2021 she went to the ER. She has no NDC, lot, or expiration date available for the Benadryl, it is at her house and she is currently at work. It was Waldryl, the store version the of Benadryl. When she had the lip swelling, it was like little blisters on her lips mainly on her top lip. The next day her bottom lip was swollen. Her tongue got big and her throat was super tight. It felt weird. Her oxygen was fine in the ER, but it felt almost heavy like there was something heavy on her. That's why she decided to go to the ER. She was already on Waldryl for a day and a half, and her lip had swelled out more and her tongue had swelled. She called urgent care, and they didn't have an appointment until 16:00 that day. They told her to go to the ER.  She had taken more Waldryl before she went to the ER so her tongue was not as swollen but her lips were pretty swollen. She has a little bit of swelling on the left, kind of like a dried blister on her top lip. It is like a dry patch of skin, but kind of like a blister. It is weird. As far as her lips there is not near as much swelling now. They gave her a shot of steroids in the ER and then put her on steroids. It is Prednisone, 20mg for 3 days. NDC: #. She does not see an expiration date or a lot number on the bottle. Her throat was kind of itchy but it wasn't tight on Saturday. She tried to go to an event on Sunday and left and came home by 11:30. She thinks the Waldryl was getting to her. She was super exhausted and dizzy. She took a nap and when she woke up her neck was stiff. Her itchy throat has gone away. It was probably yesterday when she didn't notice it anymore. She hasn't noticed it yesterday or today. She doesn't know what steroid shot they gave her or if it was Prednisone or not. They just said it was a steroid shot. She doesn't feel any throat discomfort or anything anymore. She has no more discomfort in her throat or her neck. Her lips are a little sore still in that spot with the blister, and it is a tiny bit swollen. It is her left upper lift. She has braces so when her lip swelled it could have irritated her lip. The tightness in her throat went away Sunday night or Monday morning. She doesn't really remember when it went away. She remembers not really noticing it yesterday. When she woke up from her nap her tongue was swollen and her throat was tight. She went to the ER. The swelling in her tongue and her throat went down. She doesn't remember when it went away. She hasn't been feeling good and has been out of it. She takes her last steroid tomorrow, and they wanted her to wait 2 weeks after that to get the second shot. She has to call and schedule because they only schedule a week out. She has to call back in a week or so and schedule it. The heavy feeling is gone. Everything went away at about the same time. She doesn't know when it went away. She has not noticed it yesterday or today. The steroid may have helped. She is still exhausted and kind of out of it. It could be from the steroid she is sure. She is not used to medications like that. Feeling out of it and the exhaustion still feel the same since they started. She is still dizzy. It is a little better, it is not as bad. She doesn't really know when her stiff neck went away. She has been out of it. She doesn't remember when it stopped or anything. She hasn't noticed it today. Investigations: They didn't do any bloodwork or x-rays or anything. They just gave her a steroid shot. She thought she was having a reaction to a candle. She had a candle that she burned several times in her house and never had a reaction to, but she assumed it was a reaction to that. It was the only thing around that was different, she blew out the candle. She thought it was a reaction to the candle and they weren't positive, so they gave her the steroid.
