KEYTRUDA▼ (pembrolizumab) – 50 mg vial supply arrangements

During the month of June 2019 onwards pembrolizumab will cease to be available in the 50 mg vial as lyophilised powder (50 mg powder for concentrate for solution for infusion). It will be supplied by MSD in the UK exclusively in the form of 100 mg vial (25 mg/mL concentrate for solution for infusion).

As this date is determined by the level of the demand for this presentation a precise date cannot be provided. As such we recommend that all Trusts take appropriate steps to ensure they are able to use the 100 mg presentation.
