15 May 2019 - Pharmaceutical supplier Sigma Healthcare will face shareholder questions over claims that it failed to properly handle a range of popular over-the-counter and prescription drugs that get processed through its distribution centres.

There are concerns that product quality may have been compromised due to improper handling and storage, with current and former Sigma workers saying that prescription medicines used to treat bacterial infections, depression, high blood pressure and diabetes were left out in 30 to 40 degree heat for hours over the summer months.

Workers also report that prescribed medications that require refrigeration, such as Humira (a medication used to treat conditions such as rheumatoid arthritis and Crohn's disease), were left out for hours on the open warehouse floor at one Sigma site.
