A medicament package comprises a vessel adapted to hold a quantity of a liquid vehicle. The vessel has an opening formed therein. The opening engages a deformable enclosure which receives a medicament container that contains a unit dose of a medicament. The entire medicament package is sterile and is arranged such that by deformation of the enclosure the container may be dislodged from the enclosure into the vessel whereby the medicament may escape from the container and mix with the liquid vehicle. The medicament container is formed with one or more dispensing apertures through which the medicament may exit the container and/or liquid can enter the container. The medicament container may be formed as two or more components, the integrity of the container being maintained by its engagement with the enclosure and that integrity being lost once the container is released from the enclosure.
