People warned to guard against fake weight-loss medication

People have been warned to guard against fake weight-loss medication.

The warning from the Department of Health comes amid a “significant spike in demand” for such drugs.

The department’s Medicines Regulatory Group (MRG) urged people not to turn to unregulated or unapproved sources, including unscrupulous websites, social media sellers and locally based illicit sources.

They said the potential risk to public health has been highlighted during a number of recent MRG investigations.

They said these have established falsified and unlicensed injectable weight-loss medication in circulation throughout Northern Ireland, leading to some people suffering adverse reactions and being admitted to hospital.

Peter Moore, senior medicines enforcement officer with the Department of Health, said: “MRG has received reports of several people who have been hospitalised after using potentially fake and unlicensed medication.

“Whilst we continue to recover fake and unlicensed pre-filled multi-dose weight-loss pens, we are now seeing criminals selling ‘DIY kits’ that include the active ingredient in powdered form alongside syringes, so customers can inject themselves, but must first mix the ingredients together before use.

“The mixing of ingredients and use of such kits can present additional risks to the public.”

He added: “We are committed to an ongoing programme of monitoring, investigation, enforcement action and partnership working to tackle the issue.

“Over the past three years (to date), MRG has conducted 34 investigations focusing on the unlawful possession, advertisement and/or supply of counterfeit or unlicensed weight-loss medicinal products, resulting in the recovery of 600 units of medicinal products and five successful prosecutions.”

Aaron McKendry, interim head of the MRG, said people should only take prescription-only medicines after consultation with their GP, pharmacist or other healthcare professional.

“Medicines obtained through unregulated or unapproved sources will often not have been prescribed by a healthcare professional, may not have been subject to the normal safety and quality controls on manufacture and, as such, may not be of the required quality or be of the nature described,” he said.

“Any person who suspects a medicine has been falsified should discuss the matter with a healthcare professional such as a pharmacist or GP and report the matter via the Yellow Card reporting system https://yellowcard.mhra.gov.uk/.

“The risk to public safety posed by the unlawful distribution and misuse of unauthorised medicinal products within the non-surgical cosmetic sector in Northern Ireland is a serious issue.

“Such breaches relating to Northern Ireland can be referred to the department’s Medicines Regulatory Group via counterfeit.mrg@health-ni.gov.uk for investigation under the Human Medicines Regulations 2012.”
