Before You Begin
The SKYTROFA Auto-Injector
Your healthcare provider will inform you that the SKYTROFA Auto-Injector, which comes in a separate package, is required for injecting the prescribed the SKYTROFA medicine.
The SKYTROFA Auto-Injector is exclusively for use with SKYTROFA Cartridge (medicine).
The SKYTROFA Auto-Injector automates part of the procedure for injecting SKYTROFA medicine.
The SKYTROFA Cartridge
The medicine SKYTROFA comes in a one-time use cartridge "SKYTROFA Cartridge". The cartridge has 2 chambers, 1 filled with powder and 1 filled with water. The auto-injector automatically mixes the powder and the water during mixing steps, making it ready for injection. Each SKYTROFA Cartridge pack contains 4 cartridges packed in individual blisters.
The Needle
The single-use needle comes with SKYTROFA Cartridges and is used for screwing on the cartridge to inject the medicine. Each SKYTROFA Cartridge pack contains 6 needles including 2 spare needles.
Contact your healthcare provider if you need more SKYTROFA consumables.
