A member asked:
Are you supposed to feel sick on your period because i feel really sick or is that from taking keflex my antibiotics?
A doctor has provided 1 answer
See below: All antibiotics including Keflex can cause nausea and vomiting. I recommend trying to take the antibiotic with food even though this can decrease the absorption. If the nausea persists contact your prescribing doctor.
