Every country has their own categorization of medicines which indicates which ones are allowed to be taken without any documentation, which need a prescription, ones that need more documentation and those that are completely banned.
For motion sickness pills, they are usually allowed. Pretty much any medication that is available over-the-counter at your destination country, will be allowed in.
In Canada, it is easy to purchase Gravol and I have taken those pills with me to easily over 40 different countries without ever having in issue. They have a very mild effect though and so in Brazil I switched to Meclizine Chlorhydrate. The difference is night and day. Although these are not available in Canada, I have taken them there, to the US, to Europe (Portugal & The Czech Republic), to the middle-East, Africa and Asia (11 countries in all). Again, I never had any problems taking these with me to any of these countries.
EDIT: Someone in the comments indicated that Kwells is Scopolamine. This is a highly controlled substance . In Canada and the US, it is only available with a prescription. You will need a doctor to write you a letter explaining that you need this medicine. That will not guarantee it will be allowed in though. I had a similar letter written for another medication but whether it is recognized at any of your destinations is up to them. Generally, if you are carrying a small enough quantity for personal use, theses things do not get noticed.

It might depend on what exactly the ingredients are, and especially which country you are going to. You will not have issues in the US.
In the USA, a lot of medication can be bought over the counter that need prescriptions in other countries, or that are illegal/controlled substances.
However, for a limited amount and with the original packaging - there should be little issues anywhere; it is obvious that you are not smuggling drugs, but only have a personal supply, and equally obvious that they are freely sold in the US. I wouldnβt worry at all.
To be absolute sure, you would have to compare the ingredient list with the target countryβs legislation.
