headache; This is a spontaneous report from a contactable consumer (patient). This 76-year-old female consumer (patient herself) reported that she received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Formulation: Solution for injection, Lot number: EL3246) via an unspecified route in Left arm on 16Jan2021 being 02:34 PM (at the age of 76-years-old) as single dose for COVID-19 immunisation. Relevant medical history and concurrent conditions included Blood pressure high started on 2009, Glaucoma, she had a car accident in 2009 where she got hit from behind that caused issues with her neck and she has this in her right eye, and her doctor put her on a new eyedrop in November, but other than that her meds stayed the same. Concomitant medications were not reported. Patient stated that her husband and her took the first dose of the vaccine on Saturday 16Jan2021. She says she was fine Saturday, then she woke up on Sunday morning with a headache behind her eyes that was not bad but she noticed it most of the day and then at night it was behind her eyes, the top of her head, and behind her head on 17Mar2021 at 07:00. She says she has had headaches all last week, and she took Advil and Tylenol which sometimes helped. She says she finally saw her doctor last Friday on the 22nd because she felt that was a long time for her to have headaches as a result of a vaccine and her doctor had her do a CAT scan to be sure, since she is 76, to check if she might be having a stroke or something. She says she has continued to have headaches, though not as bad as last week, and she was reading the material they got at the hospital because they are supposed to have the second shot 06Feb2021. She says she would like to know, have they had people report having headaches that long. She says she took both Tylenol, clarified to being Equate brand Acetaminophen, and Advil. Equate brand Ibuprofen 200mg: She says she normally doesn't take Advil. Equate brand Acetaminophen: She says she has two bottles one of which she keeps in the bedroom, so she doesn't know which bottle her doses came from. She says both of the Equate brand Acetaminophen bottles are extra strength, 500mg. She says when she took these two medications she was careful not to overtake or take too much, but she can't really tell how much she took. She says she thinks she first took one Tylenol and one Advil, then later that night when it really bothered her, she thinks she took maybe two Advil's and one Tylenol, but she didn't write it down. She says now her headache is not nearly like it was last week. She says that she spoke to her doctor on Friday because she was starting to get concerned about it, but it was not unbearable all day long, she would wake up with it then take something, and during the day it was better, then at night it would be worse. She says this week it mainly bothered her that it was at the back of her head and neck area, since she does have problems sometimes with headaches at the back of her head after she had a car accident in 2009 where she got hit from behind that caused issues with her neck. She says she doesn't have sinus issues, so the headache behind her eyes was odd, and since the information said side effect, it is too big of a coincidence that she got the shot Saturday and she had a headache on Sunday. probably in 2009, and she started taking Amlodipine 5mg then, and then after she retired from teaching her doctor decided she didn't need it and she stopped taking it. She says she has been taking again since about a year and a half ago, in 2018 at the end of the year. Amlodipine NDC/LOT/EXP: Unknown, it was dispensed in a pharmacy bottle, it says use before 14Nov2021. Laboratory tests included CT scan resulted negative on 22Jan2021. The outcome of the event was recovering.
