She had the first dose of the Pfizer covid19 vaccine on 28Jan2021. She is nervous. She lives with lupus and antiphospholipid syndrome, which means her blood is too thick. She is on a blood thinner, she takes warfarin. She is asking if the vaccine could interfere with warfarin. Today she had her INR checked and it was was 4.9. States a stable reading is between 2 and 3. The only different thing she has had in her body is the vaccine. Reports she is nervous and scared. She had surgery on her feet and she has a wound where a thicker scab came off, states it is draining but not drying out. She was thinking maybe this was due to her her INR being high. She will see the surgeon tomorrow. She put a bandaid on her foot where the open wound on her foot is. The next morning she checked her foot and the bandaid was wet. She put some peroxide on it. She read peroxide is not good for open wounds because it kills good bacteria so she used gauze and placed it over the open wound with tape across it. Last month her warfarin dose was 6 mg 5 days a week and 3mg two days a week. As of today she is to take 3mg three days a week and 6mg four days a week. Warfarin is 6mg tablet that is perforated, clarifies it can be broken in half. She does not think her new regimen that she was given today will bring her INR back in the range between 2 and 3. States her INR has never been that high. She will go back to see the nurse in two weeks to get her INR checked. She sees her patient medical record number listed on the card. She says pardon her grunts and moans because she grunts and moans when she moves since she is 76. She feels weird and her eyes are extra dry in 2021. She is nervous about the area where she had surgery on her feet, she does not want it to get infected. She thinks she had surgery on 04Dec2020 to have arthritis in her toes corrected. Outcome of events was unknown.
