Counterfeit medicines are a serious issue facing patients, health professionals and the pharmaceutical industry.

Counterfeit medicines are made by someone other than the original manufacturer and whilst some counterfeit medicines may have the correct active ingredient, some are dangerous as they may:

Be contaminated

Contain no active ingredient

Have been made in extremely unsanitary conditions

Include too much or too little of the active ingredient

Undermine the patients' confidence in taking medicines

Contain harmful or poisonous ingredients

MSD takes the safety of patients extremely seriously and is working with governments and customs authorities around the world to help control the problems caused by counterfeit medicines.

The EU Falsified Medicines Directive (FMD) came into force on 9th February 2019 and introduces measures to avoid falsified medicines being dispensed to patients. Measures include an anti-tamper device and a 2D matrix bar code which can be scanned to verify authenticity of medicine at key points in the supply chain, including right before dispensing to patients. This is a welcome step in the fight against counterfeit medicines. At MSD, our priority has always been and will continue to be, the safety of the patients which we serve. The new end-to-end verification system is there to ensure product integrity and authenticity of medicines given to patients.

We are committed to acting responsibly in the interests of patients. Ensuring continuity of supply of medicines and vaccines for patients is MSD’s highest priority and we therefore took all the necessary steps to seek to ensure the supply of our products was not negatively impacted once the UK left the EU. Since the outcome of the EU referendum we have worked to meet the new regulations and to ensure readiness for the end of the transition period (31st December 2020). Read more here.
