Hello,
Thank you for your query at DoctorSpring.com
Black vomiting is not associated with the i pill you took. I Pill can lead to some amount of nausea and vomiting, but never blood vomit.
Do you have any history of gastritis, ulceration, H Pylori infection, excessive alcohol intake?
You should immediately start taking the following medicines :
1) Tab. Ondansetron 8 mg, once before each meal for 2 days.
2) Cap. Omeprazole 20 mg once immediately, then once daily before breakfast for 7 days.
3) Syp. Sucralfate 2 teaspoons twice daily after meals for 7 days.
If vomiting still persists, it will be prudent to visit the ER, and get necessary investigations done.
Regards.
