A method of liquefying solid form of medication into a liquefied medication solution is implemented by a medication liquefaction system and a removable medicine container. The solid form medication, which is difficult to swallow by itself, and a desired amount of drinkable fluid base product are added into the removable medicine container before the removable medicine container is hermetically attached with the medication liquefaction system. Then a carbon dioxide (CO2) gas flow pressurizes the removable medicine container so that the solid form medication can be efficiently and quickly dissolve within the drinkable fluid base product in order to create the liquefied medication solution as the CO2 gas flow carbonates the liquefied medication solution. Then the liquefied medication solution can be consumed by the user without any difficulties.
