Discoloured vancomycin vials (December 2014)

It has been reported that some vancomycin vials (manufactured by Wockhardt UK) may contain powder with a pinkish colour. The discolouration is due to a phenomenon in the freeze drying process.  As this process does not start at the same time in all vials it can result in differences in the appearance of the final product.  Manufacturers have been contacted and confirmed that this does not affect the quality of the product and it can be safely used.
