A method and system for proving a drug delivery device. The device comprises a drug delivery device housing and a medicament contained in the drug delivery device housing. A dose dial sleeve is positioned in the housing and is rotatable to set a non-inverted dose of the medicament contained in the medical delivery device. The non-inverted dose may be increased by turning the dose dial sleeve in a direction towards a user of the drug delivery device. The dose medicament may be decreased by rotating the dose dial sleeve in a direction away from the user.
