The invention provides a bicarbonate-containing medical solution package comprising a gas-permeable plastic container holding a bicarbonate-containing medical solution and a gas-impermeable plastic packaging member accommodating the gas-permeable plastic container, with a carbon dioxide atmosphere having been established in a space defined by the container and packaging member and the space containing a pH indicating device comprising a gas-permeable plastic packet containing a bicarbonate-containing fluid (similar to the medical solution) and a pH-indicator having the property to undergo a change in color in response to a change in pH of the fluid. With this package, the change in pH and consequent aging of the medical solution due to prolonged storage or a trouble such as the incidence of a pinhole in the outer packaging member can be easily ascertained by the naked eye.
