Packing the pen
Use an insulated travel case + 1-2 small gel packs. Frio cooling wallets work without ice for short flights. For long-haul: a soft cooler with ice packs in carry-on.
Always travel with the original carton (FDA prescription label) + your prescriber's contact info. International borders sometimes ask.
Getting through TSA
TSA explicitly permits injectable medications + cooling materials. Declare them at the start of screening — "I have a prescription injection and a cold pack."
You don't need a doctor's note in the US but it helps internationally. Print one on letterhead stating the patient name, medication, indication, and prescriber contact.
Crossing time zones
For trips <5 days: stay on home-time injection schedule. Set a phone alarm for the equivalent local time.
For trips ≥1 week: shift by 24h on the day you depart, then maintain the new local-time schedule. Avoid splitting a single dose period across >9 days.
Storage at destination
Unopened pens need refrigeration (36-46°F). Hotel mini-fridges work but verify the temperature on arrival.
Opened pens: stable at room temp (below 86°F) for 28 days (semaglutide) or 21 days (tirzepatide). For trips longer than that, plan for fridge access or ship a refill ahead.
Frequently asked questions
- Can I bring a GLP-1 through TSA?
- Yes. Injectable medications + cooling materials are permitted in carry-on. Declare at the start of screening.
- Does my GLP-1 pen need to stay cold?
- Unopened: yes (36-46°F). Once opened: stable at room temp (below 86°F) for 28 days (semaglutide) or 21 days (tirzepatide).
- Can I skip a dose if I forget to bring my pen?
- Once-weekly drugs: take it within 5 days of the missed dose, then resume normal schedule. After 5 days, skip and resume next week.
- Do I need a doctor's note to travel internationally with a GLP-1?
- Not always required but strongly recommended. Print a letter on letterhead with patient name, medication, indication, and prescriber contact — saves time at customs.
