The reusable pen device for Genotropin® (somatropin) 5.3 mg and 12 mg powder and solvent for solution for injection will be out of stock from the end of January 2026 until at least early 2027. 

Each reusable pen has a battery life of approximately two years. Patients whose pen has a battery life that will expire during the out-of-stock period will need to be switched to an alternative device. 

GP practices are required to identify patients prescribed the reusable pen device. For patients whose device is nearing battery expiry, arrangements must be made to switch them to an alternative device until the supply issue is resolved. 

Homecare patients currently using this pen device will be reviewed by their homecare provider to determine whether a switch is required during the shortage, and will continue to receive supplies from their homecare provider as appropriate. 

New patients should not be initiated on the Genotropin® Pen device, and new homecare referrals will not be accepted until the supply issue has resolved. 

Only the reuseable pen device is affected. Genotropin® 5.3 mg and 12 mg powder and solvent cartridges, GoQuick® pens, and all strengths of Genotropin ® MiniQuick ® pre-filled disposable devices remain available, and can support additional demand for new patients and those requiring a switch.
