"Adewale Ajumobi, MDIt says do not refridgerate.
People have refrigerated Clenpiq without any problem despite the label. Definitely do not freeze. It is a ready to drink solution and the manufacturer do not want any dilution by way of ice or others. Bowel cleansing agents are easier to tolerate cold in general. Clenpiq is relatively small and can easily be swallowed whole and so having it cold may be a mute point. Follow your doctor’s specific instruction always."
