The Medicines and Healthcare products Regulatory Agency (MHRA) has warned the public to avoid buying pre-filled weight loss pens without a prescription.
The warning came after 369 fake Ozempic injections have been seized since January 2023.
However, Saxenda pens were obtained by members of the public in the UK through "non-legitimate routes".
The health regulator has urged the public to buy the pens after consulting a healthcare professional and with a prescription.
Dr Alison Cave, MHRA Chief Safety Officer shared her opinion on the matter, she said: "Buying products such as Ozempic or Saxenda without a prescription,
from illegally trading suppliers, significantly increases the risk of receiving something which is either fake or not licensed for use in the UK.
