Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Thanks so much for this. I called her doctor and we'll see them on Friday. Thanks to your prompting, I asked if they would like to make any changes. They haven't yet...maybe because she already started...? Thanks again!!!This was an urgent care so she probably was not seen by an actual physician.. ### Response: I think interrupting the night sleep of an elderly infected woman seems a bit of an odd choice even in the hospital.Give her one dose right when she wakes up, and one dose right when goes to sleep. Then space the others as evenly during the day as possible. (So for example, she goes to sleep at around 21:00 and awakes at 7:00 her doses should be at: 7:00-11:30-16:30-21:00).On the other hand, the active metabolite of metronidazole (flagyl) has a half-life of 9-19 hours. So taking it more than thrice daily is also odd..
