Sharon- all PB is is bismuth salicylate. It's a metal that is toxic to the bacteria in our guts which cause gastritis, upset stomach, nausea and pouchitis. If not sold under the Pepto Bismol brand, it's an utter lock that France sells it under some other name. As an over the counter. In the USA pretty much every pharmacy and supermarket has their own generic brand with the same operative ingredient as PB, bismuth salicylate. It is a distinctive pinkish color, and has a chalky taste although not as obnoxious as barium. One capful should alleviate any nausea. If it's an aggressive nausea try 2 capfuls but you can't take more than 6 or 8 doses a day (read label) as it will wreak havoc on your liver if you do. But safe if not overused and space it 2 hours from any prescription meds you are taking as it will block absorption of them.
This is what it looks like:
