After opening a drink, how long can it be kept?
Since Otsuka Pharmaceutical's drinks contain no chemical preservatives, once you take a sip, it should be consumed the same day. If you pour some into a glass, then the remaining drink can be stored in the refrigerator for one or two days, as a rule. It is a good idea to select a bottle size you can consume as quickly as possible.
