What Needles Are Compatible With My Mounjaro® (KwikPen®) Pen?
The Mounjaro® KwikPen® does not come with needles inside the manufacturer's box; MedExpress supplies these separately within your delivery parcel.
What Needle Brands and Sizes Are Compatible?
The KwikPen® is designed to work with any ISO 11608-2 compliant pen needles from major brands such as BD, Novo Nordisk, and Terumo. You can safely use any combination of the following lengths and gauges:
Lengths: 4 mm, 5 mm, 6 mm, 8 mm, or 12.7 mm
Gauges: 29G, 30G, 31G, 32G, 33G, or 34G
MedExpress Supply: MedExpress usually provides 5 mm or 6 mm needles with your Mounjaro® order.
Maximum Recommended Length: While the Mounjaro® pen is compatible with longer needles, the maximum recommended length for safety and comfort is 8 mm.
Can I Use Longer Needles With My Mounjaro® Pen?
You can use different needle lengths with your Mounjaro® pen, as long as they are compatible.
The Mounjaro® pen supports a range of needle lengths.
The maximum recommended needle length is 8 mm.
MedExpress typically supplies 5 mm or 6 mm needles.
Longer needles may be suitable for some patients depending on individual factors, but they do not change how the medication works. If you prefer a different needle length, you can purchase compatible needles from a local pharmacy.
What Should I Do If My Mounjaro® Needles Are Missing?
If your Mounjaro® needles were not included in your parcel, you have two options:
Purchase locally: You can buy compatible ISO-compliant needles from most UK pharmacies. Keep your receipt as proof of purchase — MedExpress can provide an account credit of up to £10 once this has been reviewed.
Request a replacement: If you're unable to purchase needles locally, MedExpress can arrange for a replacement pack of needles to be sent to you.
If your Mounjaro® needles were included in your delivery but have since been lost, misplaced, or disposed of, MedExpress will not provide replacements or reimbursement. In these cases, you will need to purchase replacement needles at your own cost.
What Needles Are Compatible With My Wegovy® (FlexTouch®) Pen?
Unlike Mounjaro®, Wegovy® needles are packed directly inside the box by the manufacturer.
What Approved Needle Brands and Sizes Are Compatible?
The Wegovy® FlexTouch® pen must be used with specific approved needle brands. The maximum recommended needle length is 8 mm. Compatible sizes for these brands include:
NovoFine®: 32G 4mm, 32G 6mm, 31G 6mm, or 30G 8mm
NovoFine® Plus: 32G 4mm
NovoTwist®: 32G 5mm or 30G 8mm
NovoFine® Autocover®: 30G 8mm
What Should I Do If My Wegovy® Needles Are Missing?
If you find that needles are missing from your sealed Wegovy® box, you have two options:
Purchase locally: Buy the approved Novo Nordisk needle brands listed above from a local pharmacy. Keep your receipt as proof of purchase — MedExpress can provide an account credit of up to £10 once this has been reviewed.
Request a replacement: If you're unable to purchase needles locally, MedExpress can arrange for a replacement pack of compatible needles to be sent to you.
If your Wegovy® needles were originally present but have been lost, misplaced, or disposed of after delivery, MedExpress will not provide replacements or reimbursement. You will need to purchase replacement needles at your own cost.
What Should I Do If My Sharps Bin Is Missing?
A sharps bin is included only with your first Mounjaro® or Wegovy® order. Sharps bins are not included with repeat or subsequent orders, and MedExpress does not sell sharps bins separately.
If your sharps bin was missing from your first order: MedExpress can arrange for a replacement to be sent to you. This only applies to first orders, as a first order is the only time MedExpress would have included a sharps bin with your delivery.
If you need a sharps bin for a repeat order, or need an additional one: MedExpress cannot supply or replace a sharps bin outside of your first order. Replacement sharps bins can be purchased from a local pharmacy or from general retailers.
Using and disposing of your sharps bin safely:
Sharps bins are not designed to be reopened once closed. Do not force a sharps bin open after it has been sealed.
Once your sharps bin is full, take it to your local pharmacy for safe disposal.
Never dispose of a sharps bin, or any used needles, in household waste.
If your sharps bin arrived already closed or locked:
If the sharps bin included with your first order arrived already closed or locked before you were able to use it, do not attempt to force it open. Please contact Customer Care so we can assist you further.
What Should I Do If My Wipes Are Missing?
Alcohol wipes are included with every Mounjaro® or Wegovy® order, not just your first order.
MedExpress recommends purchasing replacement alcohol wipes yourself from a local pharmacy or supermarket, since this is usually faster than waiting for a replacement to be sent. If you're unable to purchase replacement wipes yourself, MedExpress can arrange for a replacement to be sent to you.
What Safety and Handling Rules Should I Follow When Using Needles?
To ensure your treatment remains safe and effective, always follow these sterile injection rules:
One needle per dose: You must use a fresh, sterile needle for every weekly injection. Never reuse a needle, as this increases the risk of infection and can cause the needle to blunt or block.
Safe disposal: Used needles must never go into household waste. Place them immediately into your sharps bin after use.
