An apparatus includes a substrate and a wall coupled to the substrate. The substrate and the wall define a medicament reservoir. At least a portion of the wall is configured to be deformed to reduce a volume of the medicament reservoir when the wall is actuated. The wall includes an actuation portion, which can be used to actuate the wall. The portion of the wall is configured to deform at a first rate when the actuation portion is in a first configuration, and a second rate when the actuation portion is in a second configuration.
