With the growing popularity of weight loss injections like Ozempic, Saxenda and Mounjaro, counterfeit versions of these products are increasingly common in the UK, with the government publishing in 2023 that they had seized 369 potentially fake Ozempic pens. These fake pens can be harmful, leading to serious health risks. Here’s how to identify fake weight loss pens and avoid potential dangers. 

What is a weight loss pen?

Weight loss pens help reduce weight

A weight loss pen is an injectable medication designed to assist with weight loss. Packaged in a pen-like device for easy administration, these pens usually contain GLP-1 receptor agonists, such as semaglutide, found in products like Wegovy or Ozempic, or liraglutide, found in products like Saxenda. These medications help individuals manage their weight when combined with a healthy diet and exercise plan by reducing appetite and slowing down digestion.

What to look out for

1. Source of Purchase

The most important tip is that you should only buy weight loss pens from a registered pharmacy. The UK Medicines and Healthcare products Regulatory Agency (MHRA) has seized hundreds of fake Ozempic and Saxenda pens sold through online marketplaces and social media. These unauthorised sources are the primary channels for counterfeit pens, which are not only illegal but dangerous. Legitimate pens require a prescription and must be purchased from licensed healthcare providers.

2. Packaging Quality

One of the key ways to identify a fake pen is by examining the packaging. Genuine pens will have high-quality packaging with clear labels and precise information. Counterfeit versions often have poorly printed or faded labels, and packaging that doesn’t match official branding. Look out for: 

  • Spelling mistakes or incorrect information. 
  • Unusual logos or labels that peel off easily. 
  • Incorrect batch numbers or mismatched expiry dates. 

3. Side Effects and Unusual Reactions

Counterfeit or fake weight loss pens may contain substances like insulin instead of semaglutide, leading to potentially life-threatening side effects. Some users have reported incidents of hypoglycaemic shock and even coma after using fake weight loss pens. If you experience unusual side effects, such as dizziness, confusion, or excessive sweating, stop using the pen immediately and seek medical help. 

Stay Safe

Use a trusted and licensed pharmacy

With the increased presence of counterfeit products, the best protection is being cautious about where you purchase your weight loss medication. Always opt for a registered pharmacy and consult a doctor or pharmacist for your genuine prescriptions. Avoid buying products off social media, such as Instagram. By following these tips, you can minimise your risk of using a fake and potentially harmful product. 

For further information, the MHRA also offers tools via its #FakeMeds campaign to help consumers avoid fake medical products. If you have encountered a counterfeit weight loss injection, you can report it to the MHRA’s yellow card scheme.
