Unfortunately, you never know what could happen when your traveling. When you need to regularly need to take medicine, this possibility can be unsettling. That’s why we bought these for my husband. He always keeps 3 days worth of his medicine with him at all times in one of these waterproof containers, in addition to bringing his weekly pill organizer. And if we are doing a trip together to a foreign country, I will often take the other container filled with his medicine as well. (BTW: We also have a letter from his physician explaining what medicine he takes.) We have never had to use these, but again, we are prepared. These are the large containers and you might not need them so big. So, if you like the idea of carrying medicine with you, but don’t need such a large container, there are smaller ones too, like these https://amzn.to/4dzpa4y. These waterproof containers are also great for holding other small items you need to keep protected, like earplugs, jewelry, etc.
