Looks like you are giving an antibiotic, and the cimetidine is an antacid to help settle the stomach.
So, if she can sleep, eat, drink, no vomiting, you are in pretty good shape.
Make sure to get a fecal test performed! Parvo is viral, but a fecal test is a must for all puppies!
Bring in a fresh poop sample to the veterinarian. Ideally, within a few hours. Request that it be sent “OUT” to the laboratory instead of being looked at in the hospital (more accurate that way). We are not interested in only worm eggs, but also checking for the very common microscopic bugs like giardia and coccidia. These types of parasites will not be cured with over-the-counter dewormers. Giardia can also be difficult to identify on routine fecal tests, so ask your vet if they always add a “giardia elisa” to the fecal test.

If she can sleep, I think there is nothing further, at this point, to be worried about, but make sure to follow up with your vet.
Hope that additional information helps. Definitely, reply to me if there is any other way I may assist you. I hope my responses have been satisfactory?
