A disposable pen needle assembly for affixing to a pen injector for injecting a medicament, such as insulin, into a user. The pen needle assembly includes a needle that is sealed within a hub such that a proximal end of the needle is retained within the hub and enclosed by a peel-off hub inner seal. The opposite end of the needle extends outwardly for injecting the medicament. There is a sealed chamber external of the peel-off hub inner seal that contains a swab soaked with an antiseptic material. An outer removable seal, that also can be a peel-off seal, covers the sealed chamber containing the swab so that the user can simply remove the outer seal to gain access to the swab for cleansing the potential injection site. After swabbing the injection site, the hub seal is then also peeled off to access the needle for use in conventional manner.
