An ampule for an automatic hypodermic syringe comprises at least two axially aligned and hermetically separated compartments containing respective medicated substances. A nipple member is disposed at one end of the ampule. A needle holder is slidably mounted in said nipple member and supports a hollow needle. An intermediate partition normally hermetically separates the two compartments. The intermediate partition has a valve member adapted to open a path of flow through the intermediate partition to bring the second of the compartments into communication with the needle hollow after a first of the compartments is substantially emptied. Preferably, there are two intermediate partitions and three compartments.
