She can breathe better moving around but when she sits down, her breathing seems to be congested; Nose started stuffing up again; Her nose just swells; congestion in her chest; her arm was sore/ Little pain in her right leg; This is a spontaneous report from a contactable consumer (patient). A 77-year-old female patient received her first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: EL9265) solution for injection, intramuscular on right arm on 01Feb2021 at 09:10 AM at single dose for COVID-19 immunization. Medical history included breathing problems and COVID-19 on 31Oct2020 in which she waited exactly 90 days to get the vaccine. The patient had a small touch of pneumonia on her lower lobe of her right lung, she was on a lot of antibiotics and a strong herbal solution. She was on one antibiotic for 5 days and another for 7 days. She was on the herbal stuff for 7 days. She took all that stuff and was drinking lemon juice and hot water and breathing in lemon scent and Vicks Salve all in her nose. She also was prescribed an asthma pump. She had all that stuff going into her system. She also was tested, and she has H. Pylori bacteria. She explained her whole family must have that, it's hereditary. That wasn't her issue. However, all that she put in her stomach and in her system caused her to have stomach issues. She told the doctor that antibiotics made her sick. She told the person administering the vaccine that antibiotics made her sick and she was told it didn't matter and that this wouldn't interfere with the COVID-19 vaccine. Her stomach was all messed from all that stuff. The patient also has anxiety. She has never been treated with anxiety. She has had anxiety since she was a very young women and she has never been treated for it. When probed for any product information she had available for the medications that messed her stomach up and made her sick she provided the following information: The first medication she took was azithromycin (Z-PAK, lot number: KG0706, expiration date: Nov2021, NDC number: 0781-8089-26) that was dispensed in a little box. Dose was 250 mg which she took daily doses for 5 days. One of the doctors gave her a levofloxacin 50 mg for 7 days. She was given the pump, salbutamol (ALBUTEROL SULFATE HFA INHALATION AEROSOL, lot number: 102B4, expiration data: 20Jan2022) 90mcg per actuation. She explained she only took this once. She was so scared from this stuff. It squirted down her mouth. Another doctor prescribed her omeprazole 40 mg capsule every day because she told him her stomach was messed up. The patient was prescribed amoxicillin 500 mg tablet, take one tablet, by mouth three times daily for 14 days and clarithromycin 500 mg tablet, take one tablet by mouth twice daily for 14 days. The new doctor also had her taking omeprazole (the doctor wrote another prescription for this). However, this time the dose was 20 mg and she was prescribed to take that twice daily for 14 days. She didn't finish this medication. She told the doctor that antibiotics made her sick and the doctor explained because of her bacteria, she ordered the antibiotics to make her feel better. The patient told the doctor if she could live like this, let her not take these medications until she gets her stomach better and she would eat healthy food and find natural antibiotics at the health food store. She mentioned using oregano. She took that once a day. When she knew she was getting ready to take the COVID-19 vaccine, she stopped taking that 2 weeks before taking the vaccine. She stopped taking cholesterol medicine at night 2 weeks ago, it was making her sick to her stomach. She stopped her potassium medicine. She didn't want any of the medicines interfering with the vaccine. The patient also took an herbal medicine that was called a Spiritual, Mental, Emotional, Elevation Science of Eternal Life. It's a detox mixture that was very strong. She took this for 7 days. She had lost weight because she was not eating. The patient has always been a junk food eater. She quit eating junk food and that probably also had something to do with her being sick. She cooks all her food. There was no additional vaccine administered on the same date with COVID-vaccine. The patient has no prior vaccinations within 4 weeks. She has never had a flu vaccine, pneumonia vaccine or shingles vaccine. This was her very first vaccine. Concomitant medication was reported as none. The patient didn't know if it was anything serious, but she tried to read all the information that was given to her. She was looking at the information and she saw "if you have any difficulty breathing". That was the only one that she was having. She could breathe better moving around but when she sits down, her breathing seems to be congested. She was calling to see if this was anything serious and if she needed to go the emergency room. Since her breathing has been acting funny, she has been trying to keep moving around. She was cleaning her bathroom and the Bleach Cleaner and other cleaner opened her nose. She was listening to a town hall meeting and when she sat down to listen to it, her nose started stuffing up again. She has just been trying to get up and move around. Since she has been talking on the phone, her breathing was a little better. Her nose just swells. She got up and was beginning to eat breakfast when all of a sudden, the difficulty breathing started happening. It was around 8:45 am this morning (02Feb2021). It has improved, but when she would sit down, it would tighten up and she would have congestion in her chest. Since she has been moving around talking, it has gotten better. Sitting down has something to do with the difficulty breathing. She has had breathing problems before. The patient received the COVID-19 vaccine yesterday, 01Feb2021. She sat for half an hour afterwards and then came home. She then slept all night and stated her arm was sore on Feb2021, but it was feeling better. She also had a little pain in her right leg on the side she received her vaccine on Feb2021, which was currently gone. She wasn't sure if the breathing problems were from the vaccine or something else. The patient did not go to the emergency room or visited his physician in response to the events. She mentioned that if this continues, she probably will go to urgent care. The outcome of the event dyspnea at rest and respiratory tract congestion was recovering, recovered on Feb2021 for pain in extremity, and unknown for all other events.
