Department of Health and Social Care (DHSC) has issued a medicine supply notification for Tresiba Flextouch 100units/ml solution for injection 3ml pre-filled pens

Information is available on website: Medicine Supply Notification: Tresiba (insulin degludec) FlexTouch – Community Pharmacy England (

Date of issue 24th May 2023 amended

  • Tresiba® FlexTouch® (Insulin degludec) 100units/ml pens will be out of stock from August 2023 until January 2024.
  • Tresiba Penfill® (Insulin degludec) 100units/ml solution for injection 3ml cartridges remain available and can support increased demand.

The shortage only affects people using prefilled pens. These people will need a new prescription to change them to Tresiba 100units/ml cartridges and a reusable pen, the NovoPen 6. If you have not used a disposable pen before, you may need to be shown how to load and change an empty cartridge by your healthcare professional.

The NovoPen 6 comes in two different colours, so it is advisable to have different coloured pens for different insulins.

NovoPen® 6 & NovoPen Echo® Plus are intended for patients who have been prescribed Tresiba® or Fiasp®. NovoPen® 6 offers a 60-unit maximum dose in 1-unit dose increments. NovoPen Echo® Plus offers a 30-unit maximum dose in 0.5-unit dose increments.
