gastroenteritis
"Originally I was prescribed this med for the nausea accompanying irritable bowel syndrome, because my nausea was debilitating. Zofran definitely took the edge off.  Now I have gastritis which causes nausea and pain. Unlike other patients, I do not get great relief. Sometimes it takes the edge off. Then I am able to eat and drink and be functional.
But right now, the pain and nausea of the gastritis has trumped the med, I feel pooly."
