Overview
GLP-1 weight loss medications need to be kept within a safe temperature range. How we pack them depends on the medication:
Mounjaro is shipped in insulated packaging with ice packs.
Wegovy is shipped without ice packs. Stability testing has shown it doesn’t need them during delivery.

Ice Packs and Delivery
My Mounjaro ice packs have melted. Is that a problem?
It is normal for ice packs to partially or fully thaw during delivery. As they melt, they absorb heat, helping to keep your medication cool. Melted ice packs do not necessarily mean your medication has been exposed to temperatures outside the required range.
Our insulated packaging has been tested to maintain the required storage conditions for up to 48 hours under validated delivery conditions.
If your delivery arrives within 48 hours of dispatch, place your medication in the refrigerator (2°C–8°C) as soon as you receive it.
If your delivery has taken longer than 48 hours, or you have concerns about its condition, please contact our Customer Care team before using it.
My Wegovy arrived without ice packs
This is expected. Wegovy can be transported without ice packs under controlled delivery conditions.
Stability data supports shipment at temperatures below 30°C for up to 48 hours. Once your medication arrives, please place it in the refrigerator (2°C–8°C) as soon as possible.
What Happens If My GLP-1 Delivery Arrives Within 48 Hours of Dispatch?
Our delivery arrangements are designed to maintain appropriate conditions for your medication for up to 48 hours.
If your medication arrives within this period, and there are no concerns about its condition or the delivery, please place it in the refrigerator (2°C–8°C) as soon as possible.
Provided the medication has been transported and stored appropriately, an unused pen can be kept until its printed expiry date. Once you start using a pen, the applicable in-use storage period must be followed.
What Happens If My GLP-1 Delivery Arrives After 48 Hours?
If more than 48 hours have passed since dispatch, we cannot guarantee that your medication has remained within the required temperature conditions throughout delivery.
Please do not use the medication. Contact our Customer Care team, and we will arrange a replacement.
How Do I Check the Dispatch Time for My Order?
You can check when your order was dispatched by referring to the dispatch confirmation email sent to you by MedExpress. The date and time of this email mark the start of the 48-hour temperature-controlled delivery window.
How Long Can I Use a Pen After My First Injection?
Mounjaro KwikPen: Use within 30 days of your first injection, or until all four prescribed doses have been administered, whichever comes first. Dispose of the pen after this period, even if medication remains.
Wegovy FlexTouch: Use within six weeks of your first injection, or until all four prescribed doses have been administered, whichever comes first. Dispose of the pen after this period, even if medication remains.
Wegovy 7.2 mg single-dose pen: Each pen contains one injection and must be discarded after use.
When Might a GLP-1 Pen Not Be Safe to Use?
Do not use your medication and contact our Customer Care team for advice if:
Your delivery arrived more than 48 hours after dispatch.
Your medication has been frozen, or you suspect it may have frozen.
The solution appears cloudy, discoloured, or contains visible particles.
The pen appears damaged.
You are unsure whether your medication has been stored or transported correctly.
If you have any concerns about the condition or suitability of your medication, please contact us before using it.
