TSA & airport screening

The Transportation Security Administration permits medically necessary medications in carry-on luggage with no liquid-size limit. GLP-1 pens, ice packs, and Frio cooling wallets all qualify.

  • Carry-on only. Never check medication. Cargo hold temperatures drop below freezing on long flights and pressure changes can damage pens.
  • Declaration is optional but recommended. Tell the screening agent: “I have prescription medication and a cooling pack.” This usually results in a visual inspection without removing items from the bag.
  • Keep the pharmacy label visible. Pens with the original pharmacy label are processed faster than loose pens in a generic case.
  • Sharps disposal. Used needles must travel in a TSA-compliant sharps tube. Most pharmacies sell travel-size versions; do not put loose needles in your bag.

Refrigeration in transit

GLP-1 pens are stable at room temperature for 28–56 days once in use, but unopened pens require refrigeration. Plan your cooling based on trip length and starting condition of the pen.

  • Wegovy

    Fridge (unused)
    2–8°C
    Room temp (in use)
    28 days at ≤30°C

    Never: Freeze

  • Ozempic (in-use)

    Fridge (unused)
    2–8°C
    Room temp (in use)
    56 days at ≤30°C

    Never: Freeze · sunlight

  • Mounjaro / Zepbound

    Fridge (unused)
    2–8°C
    Room temp (in use)
    21 days at ≤30°C

    Never: Freeze

  • Rybelsus (tablets)

    Fridge (unused)
    Not required
    Room temp (in use)
    Room temp OK

    Never: Humid bathroom

For trips under 24 hours, a Frio evaporative cooling wallet (around $30) keeps pens cool without ice for up to 45 hours. For longer trips, an insulated lunch bag with a small ice pack works — just make sure the pen never touches the ice directly.

International travel & customs

Documentation requirements vary by destination. Carry a doctor letter for every international trip — most countries accept it without question, and the few that require pre-approval will reject you faster without it.

UK & EU

Doctor letter accepted at customs. No quantity restrictions for personal supply (typically up to 3 months).

Canada

Personal supply up to 90 days permitted with prescription. Health Canada has approved Ozempic, Wegovy, Mounjaro.

Australia

TGA Personal Importation Scheme allows 3-month supply. Print and carry the TGA personal-import statement.

UAE & Singapore

Stricter controlled-substance rules. Confirm with the embassy before travel — some require pre-approval.

Japan

Yakkan Shoumei (import certificate) may be required for >1 month supply. Apply 2 weeks in advance.

Mexico

GLP-1s available at Mexican pharmacies sometimes without prescription — but bringing your U.S. prescription is the safer path.

Time-zone dose timing

Weekly dosing gives you flexibility. Small time-zone shifts (under 6 hours) require no adjustment. Large shifts call for one of two approaches:

Anchor to local clock time

Take your next dose at the same local clock time on your usual injection day. If you inject Sundays at 8 AM, you continue to inject Sundays at 8 AM in the new zone. The effective interval shifts but the routine stays simple.

Shift the day forward / back

You may shift your injection day forward or back by up to 2 days without losing effect. Useful for short trips: shift early so the next dose lands after you return home.

Do not double up. If you miss a dose entirely and the next dose is more than 2 days away, take the missed dose. If it is within 2 days of the next dose, skip the missed dose and resume schedule. Never take two doses in the same week.

Storage at your destination

  • Hotel minibar fridge. Almost all hotel fridges hold 2–8°C. Check the temperature reading on the first day — adjust the dial to a medium setting if it runs too cold (frozen pen = dead pen).
  • Cruise ships. Cabin fridges typically work. Request a refrigerator from guest services if your cabin does not have one — most ships stock them for medical needs.
  • No fridge available? An in-use pen is fine at room temperature below 30°C (86°F) for the full manufacturer window. If you only have unopened pens, contact a local pharmacy — most will hold medications for traveling patients.
  • Beach / tropical destinations. Direct sunlight degrades the medication. Keep pens in a shaded cooling wallet, even when stored indoors with AC.

Frequently asked questions

Can I bring my GLP-1 pen through TSA security?

Yes. TSA permits medically necessary medications in carry-on luggage with no liquid-size limit. Keep the pen in its original pharmacy-labeled packaging when possible, and inform the screening agent that you are carrying prescription medication. Ice packs or gel coolers that accompany medication are also permitted.

Does Wegovy need to stay refrigerated during travel?

Unopened Wegovy pens should be stored at 2–8°C (36–46°F). However, the manufacturer allows up to 28 days at room temperature (below 30°C / 86°F) for in-use pens. A Frio evaporative cooling wallet or an insulated bag with a small ice pack is sufficient for travel up to 12–24 hours. Avoid freezing the pen — discard if it has frozen.

How do I handle the weekly injection across time zones?

GLP-1 medications are dosed weekly, so a few hours of timing variation does not affect efficacy. If you cross 6+ time zones, take your next scheduled dose at the same local clock time on your usual injection day in the destination time zone. Shifting the day forward or back by 1–2 days is acceptable; consult your prescriber if you need to skip more than that.

Do I need a doctor letter for international travel?

For travel within the United States, no letter is required. For international travel — especially to the UK, EU, Australia, and Canada — a doctor letter on official letterhead listing the medication name, dose, and indication makes customs clearance smoother. Some countries (UAE, Singapore, Japan) have stricter controlled-medication rules; check the destination embassy guidance before departure.

What if my pen is lost or damaged while traveling?

In the U.S., a pharmacy can often refill an out-of-state prescription with proof of insurance or a fax from your prescriber. Internationally, contact your travel insurance immediately for prescription replacement coverage, and reach out to the manufacturer support line (Novo Nordisk: 1-833-468-3936 / Eli Lilly: 1-800-545-5979). Carry these numbers saved in your phone.

Can I freeze a pen if my hotel fridge is too cold?

No. GLP-1 pens must never freeze. Frozen pens can release inconsistent doses and damage the protein structure. If a pen has frozen at any point, discard it and use a backup or get a replacement at a local pharmacy. Hotel minibar fridges are usually fine — set the dial to "moderate" if temperature is adjustable.
