Online vet, Dr. Marie

Dr. Marie replied:

Roundworm medicine usually kills the worms within 24 hours. You do also need to do a second dose within 10-14 days to get any worms that were just in their egg stage when the first treatment was done.

A normal cat should not have constipation or diarrhea. So, unfortunately it does sound like she will need to see a vet.
