How to Store and Travel With Your GLP-1 Pen: Checklist!
You have booked the flights, planned the itinerary, packed far too many clothes and probably already decided where you are going to eat. Then comes the slightly less glamorous question: “What do I do with my Mounjaro, Wegovy or other GLP-1 pen while travelling?”
For people taking GLP-1-based medicines for diabetes or weight management, travelling does not have to mean disrupting treatment. But these medicines do need a little planning around storage, air travel, dosing schedules and paperwork. This guide covers each in turn and ends with a print-and-tick checklist.
1. Keep Your Pen With You
Carry your GLP-1 medication in your cabin baggage, not in checked luggage. Checked baggage can be exposed to temperature extremes, and losing a suitcase is a remarkably effective way to lose access to your medication too.
Indian airlines advise passengers to carry medication in cabin baggage. Air India notes that prescribed medicines can be carried when medically necessary and may need supporting documentation at security; IndiGo states that prescribed medicines are permitted with an appropriate prescription. [2, 3]
2. Storage Matters More Than You Think
One of the most common mistakes is assuming that all GLP-1 medicines have the same storage requirements. They do not. Instructions differ between medicines, formulations, and between an unopened and an in-use pen, so always follow the leaflet supplied with yours.
As one example, the current Mounjaro prescribing information states that unopened product is stored at 2°C–8°C and may be kept at room temperature up to 30°C for a specified period, depending on the presentation. [4] The instructions for the product available to you may differ, so your local product information takes precedence.
The practical rules are simple:
• Never freeze the pen. Do not place it directly against frozen ice packs; excessive cold can be just as problematic as excessive heat.
• Protect it from heat and sunlight. Never leave it in a parked car.
• Keep it cool if your product needs it. Use an insulated medication travel case with cool packs suitable for your product, with the pen kept separate from the packs. Cool packs are for holding the permitted temperature, not for chilling the pen towards freezing.
• Plan ahead for your destination. Arrange appropriate storage before you arrive.
3. Air Travel and Paperwork
Prescription GLP-1 medicines can be carried when travelling by air, subject to airline, airport-security and destination-country requirements. For Indian travellers, it is sensible to carry:
• The medication in its original packaging
• A valid prescription
• A doctor’s letter where appropriate, particularly for international travel
• Your injection supplies (see section 5)
• Documentation for any additional medical equipment
For international travel, check the airline’s current policy and the destination country’s medication-import rules before departure. Pack enough medication for the whole trip with a small buffer for delays, and make sure you also have enough for the journey home.
4. Plan Your Injection Around Travel
Ideally, travelling should not require you to change your GLP-1 schedule. If you take your medicine once a week, plan around your travel dates so that you can keep to your prescribed day. Note your injection dates, and know the missed-dose instructions for your specific medicine, because these are not identical across GLP-1 products.
If you are crossing time zones, the approach depends on the medication and its prescribing instructions. For a short trip, the difference may be easy to manage. For longer international travel, discuss the timing with your prescriber in advance.
Two things to avoid. First, do not take an extra dose simply because your travel schedule has changed. Second, do not increase your dose just before a holiday on the thinking that “I am travelling next week, so I will increase the dose now and get ahead of things.” GLP-1 medicines are titrated gradually so that the body can adjust and gastrointestinal side effects are reduced [4, 5]. A dose increase can cause nausea, vomiting, diarrhoea, constipation or abdominal discomfort, which is particularly unwelcome before a long flight, road trip or international holiday. Change your dose only according to the prescribed titration schedule and medical advice.
5. Do Not Forget Your Injection Supplies
Pack enough compatible needles for the entire trip, plus a few extras in case of delays or damage, and keep them with your medication. Carry spirit swabs if these are part of your usual routine, and follow the instructions supplied with your device. For international travel, carry sufficient supplies rather than assuming you can easily buy the correct equipment at your destination.
Used needles should not go loose into a hotel-room bin or ordinary rubbish. Use an appropriate sharps container where available and follow local disposal guidance.
6. Eating and Drinking While Travelling
Travel often means irregular meals, restaurant food and the occasional decision to eat something simply because you are on holiday. GLP-1 medicines can reduce appetite and delay gastric emptying, so very large or heavy meals may be less comfortable than they used to be. A few practical strategies can help:
• Eat slowly and start with smaller portions.
• Stop when you feel comfortably full.
• Stay adequately hydrated.
• Be cautious with very fatty or heavy meals if they trigger symptoms for you.
If you drink alcohol, be mindful of how it affects you, particularly if you have diabetes or are taking other glucose-lowering medicines.
7. A Symptom-Care Kit: Ask Your Doctor First
Nausea, indigestion and other gastrointestinal symptoms can occur with GLP-1 medicines, and depending on the person, constipation or diarrhoea may also occur. If you are travelling somewhere unfamiliar, discuss a small symptom-care kit with your treating physician before departure, rather than trying to find a pharmacy at the last minute. Options to ask about:
• A prescribed anti-emetic for nausea or vomiting, if your physician considers it appropriate.
• An antacid or other indigestion treatment if suitable for you.
• A mild constipation treatment, such as lactulose syrup, only if recommended by your physician and appropriate for your symptoms.
• A diarrhoea medicine only after checking with your clinician or pharmacist. Avoid self-treating severe diarrhoea, bloody stools or diarrhoea with fever.
• Oral rehydration solution (ORS) sachets to replace fluids and electrolytes if diarrhoea or vomiting occurs; prepare exactly as directed on the packet.
• A probiotic, such as a lactobacillus-spore preparation, only if your physician recommends it; probiotics are not a substitute for rehydration or medical assessment.
Do not automatically pack or take everything on this list. The right choice depends on your medical history, other medicines and symptoms.
8. What If You Become Unwell While Travelling?
Most people taking GLP-1 medicines travel without major problems. However, do not assume severe symptoms are simply a routine side effect, and do not ignore them. Seek urgent medical assessment for:
• Persistent or severe vomiting, or being unable to keep fluids down
• Significant dehydration
• Severe or persistent abdominal pain
• Blood in the stool, or fever with significant diarrhoea
• Fainting or marked weakness
• Symptoms of a serious allergic reaction
• New or worsening visual symptoms
• Severe symptoms of very high or very low blood glucose, particularly if you have diabetes
If you have diabetes and become acutely unwell while travelling, your usual sick-day plan and diabetes medicines also need to be considered.
