下痢止め is the everyday term used by the general public and pharmacists. 止瀉薬 is a technical medical term used by doctors and in official drug information. In a pharmacy, asking for 下痢止め is perfectly natural.
下痢止めをください。
Please give me an antidiarrheal.
Avoid using 胃薬 (stomach medicine) when you specifically mean antidiarrheal. 胃薬 is for stomachaches, heartburn, etc., not diarrhea. Use 下痢止め to be precise.
Literally 'intestinal regulator'. Often used for probiotics or mild antidiarrheals that normalize gut flora rather than forcefully stopping diarrhea. Not a direct equivalent but sometimes grouped with antidiarrheals in Japanese drugstores.
This is not a direct antidiarrheal; it regulates intestinal function. Use only when referring to probiotics or mild regulators.
整腸剤も一緒に飲んでいます。
I'm also taking an intestinal regulator.
