Originally was vomiting for over 24hrs can i take zofran (ondansetron) and motrin together? zofran (ondansetron) gives me bad migraines. i also had a black bowel movement.

There are others: you might want to avoid zofran if it gives you a migraine. motrin can cause GI bleeding, which can cause black stools. might want to see a Physician to have your stool checked for blood. There are other meds you can take for nausea such as reglan (metoclopramide).

Black, tarry: malodorous BM could be due to GI bleeding. Please advise your Dr.

GI bleed?: Advise you se your doctor for checkup & stool exam.
