The second dose was given by the pharmacist. On the first one, they put on 22Apr2021. She was not sure why on the second one it has C, but maybe that was how the person writes a 5 and that was supposed to be for 13May2021. Stated that, they need to print, people need to understand.

When she didn't take it, she didn't go to work because she was so panicky. She felt her normal anxiety without the pill but didn't feel the other side effects from the medication. They took her off and told her to take it again. They said to take it for 2 days and see if it will come back. They had to exhaust every other thing. She was taking other medications too such as blood pressure and cholesterol medication. She started cholesterol medication last year. Treatment was received for the events. The outcome of the events was unknown.  Follow-up attempts completed. No further information expected.
