Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
You're suffering from mild gastritis, and you need to start Ranitidine 150 mg, to be taken twice daily after food, along with Syrup. Sucralfate 2 teaspoons after meals.
For your nausea and vomiting, you need to take Tab. Ondansetron once before meals. That will control your vomiting. The other two will help relieving your gastritis.
Regards.
