Filix Pharma uses blisters for our products. With a blister (costly solution) package (safety and quality feature), each pill cavity protects the dose inside until it is removed, presumably for consumption immediately or shortly thereafter. Bottles can be deceiving when it comes to product quality as stability data that allows that product to have the necessary barrier protection until the initial opening of the bottle. Once the cap is removed (and induction seal broken) to fill the first prescription, the barrier is never the same. Each time the bottle is opened, the ambient air and humidity of the room is introduced to the remaining product inside. The result of a 2015 study published by the Healthcare Compliance Packaging Council (HCPC) points to degradation risks associated with plastic bottles. The study supports concerns pertaining to exposure to moisture and oxygen, and the associated impact on medications degradation - even under normal usage conditions.
