Described herein is a drug product delivery device and method of delivering a drug on a swab. The drug product delivery device may include an applicator platform housed within a rigid housing. The applicator platform may be in the form of a plunger. One or more fluidic channels carry fluid from a storage chamber to an applicator. A frangible seal is attached to the plunger between the storage chamber and the applicator. The frangible seal blocks the fluid from moving from the storage chamber into one or more fluidic channels. Actuation of the plunger causes the frangible seal to be ruptured, which causes the fluid to exit the fluid storage chamber and enter into the one or more fluidic channels. The one or more fluidic channels carry the fluid to the applicator.
