Why YSK: there are times when you need to not be stinky. A multi-day outing with friends staying in one house comes to mind. Taking bismuth subgallate will make even your vilest poops and farts smell like absolutely nothing. In the US, it’s FDA approved for that purpose and comes in chewable tablets.
The suggested use for anyone not bothering to look this up is to deodorize gas and stool but it’s suggested use is for people with colostomy or exposed stomas where smelly gas and stool is a constantly expelled or people with chronic gas and liquid stool.
I wouldn’t want to stick any drug in my body just to stop farting in social situations. Every drug has or could have side effects even Tylenol or aspirin.
Tylenol/acetaminophen/paracetamol is actually very dangerous. Almost surprising that it’s allowed over the counter.
