If you're talking about a package like this, it's technically called a "blister pack."
When I bought multivitamin capsules from the drugstore, they gave packed capsules, not in bottles, but in some foil.
Question : What do you call group of capsules in foil, say there are 4 in a group?
We call it ¨banig¨"in Filipino. There are four capsules in a ¨banig¨.
In the UK you cannot buy antibiotics across the counter. They are only available by prescription. Most come in blister packs.
If we are buying multivitamins, they either come in plastic bottles, or in packets containing a month's supply in blister packs.
