Choose the right instructions.
This guide covers the reusable NADFlow starter kit. The original £249 pen arrives pre-filled and does not require you to insert a cartridge. Follow the device-specific instructions supplied for your exact product.
Before you start
Use this overview alongside your device’s instruction sheet and the technique demonstrated by a qualified healthcare professional. If your instructions or dose plan are missing or unclear, ask before using the product.
-
01
Get ready
Wash and dry your hands. Set out the reusable pen, matching cartridge, a new needle, alcohol wipe and sharps container on a clean surface.
-
02
Check your pack
Check the cartridge name, strength, expiry and packaging. Do not use a cloudy solution or damaged pack. Keep your pen for your own use.
-
03
Load the cartridge
Remove the cap and open the cartridge holder. Insert the matching cartridge in the orientation shown in the supplied device instructions, then close the holder securely.
-
04
Attach a new needle
Fit a fresh sterile pen needle. Keep protective covers in place until the device instructions tell you to remove them. Never reuse or share a needle.
-
05
Prime and set the pen
Follow the exact priming instructions for your device and cartridge. Set only the dose confirmed for you. A unit marking is not an interchangeable NAD+ dose across different strengths or pens.
-
06
Prepare the site
Use the subcutaneous site and technique you have been shown. Clean the area with an alcohol wipe, let it dry, and change the site each time.
-
07
Complete the injection
Operate the pen as its manufacturer directs. Keep it steady and follow its instructions for confirming delivery and the required hold time before removing it.
-
08
Dispose and refrigerate
Place the used needle in a suitable sharps container. Replace the cap, refrigerate the NAD+ cartridge at 2–8°C and protect it from light. Do not freeze. Follow local sharps collection arrangements.
Dose & frequency
Follow the product-specific dose and frequency confirmed for you. This page does not assign a dose, priming-unit setting or injection schedule. Do not transfer settings from the original pre-filled pen to the reusable device.
