📈 Track your weekly doses across the trip
The free GLP-1 Plotter logs each dose date and builds a plasma-level curve — useful for visualizing where each injection falls during your trip and confirming you don't miss a week.

Carnival's Official Policy Highlights
Carnival's Medical Services FAQ states: "Travel with your medication in your hand luggage. Keep your prescription medication in its original packaging and bring a copy of the prescription." This guidance applies to all injectable medications, including GLP-1s, peptides, and TRT.
For those traveling with injectable medication who need a sharps disposal container, Carnival advises contacting the Medical Center or housekeeping. It's also worth requesting a sharps container via the Special Requirements form before sailing so it's waiting in your cabin.
Regarding refrigeration: Carnival states that mini-bars are designed for beverages and should not be used for medications requiring specific temperature; portable medi-coolers are available in limited quantity, or the Medical Center will arrange storage during operating hours only. All medication must be labeled with your full name and cabin number.
Preparing Your Injectable Medications or Peptides
- Carry-on only: Keep vials, BAC water, syringes and any injectables in your hand luggage, not checked bags.
- Labels matter: Wherever possible, use original pharmacy containers. If you use travel vials, add your name, contents and date.
- Doctor's note recommended: While Carnival does not require a specific form for all injectables, carrying a prescription or physician letter gives extra peace of mind if questions arise at the port or terminal.
- Sufficient supply: Bring enough medication for the duration of the cruise plus extra days in case of delay. Carnival's medical centers cannot guarantee refills onboard.
Onboard Storage, Sharps & Refrigeration
- Sharps disposal: Request a sharps container through housekeeping or Medical. Secure disposal is mandatory for syringes, vials, or needles — do not toss used sharps in cabin trash.
- Refrigeration & medi-coolers: If your peptide or medication requires refrigeration, do not rely on the cabin minibar. Carnival offers portable coolers on a first-come basis (12" x 12" x 12" max carry-on coolers permitted) or Medical Center storage during operating hours only.
- Labeling for storage: All medication stored onboard must be labeled with your full name and cabin number. Use a dedicated storage case for organization and security.
Flight/Embarkation Tips (Carry-On, TSA, Port)
When flying to embarkation or between ports, treat injectable medications like other medical supplies: keep them in carry-on, accessible, clearly labeled, and be prepared to declare. Extra care if your itinerary includes international ports — check destination customs rules in advance. TSA allows medically necessary liquids and unused syringes when accompanied by injectable medication; declare them at the checkpoint.

FAQ
Do I need to tell Carnival I'm bringing injectable medications?
Yes — for best service and accommodations including sharps containers and refrigeration, complete the "Special Requirements Information" form at booking. This ensures the medical staff and your cabin steward are prepared on day one.
Can I use the minibar or room fridge for temperature-sensitive peptides?
No. Carnival explicitly states that mini-bars are for beverages only and are not suitable for medication storage — they run warmer than the 2–8 °C range peptides require. Use a medically approved cooler, a Carnival-issued medi-cooler, or request Medical Center storage during operating hours.
What about bringing needles/syringes for peptides?
You'll need safe disposal via a sharps container in your cabin. Request one in advance via Guest Services, Housekeeping, or the Special Requirements form. Bringing your own travel-size sharps container is a safe backup in case the request is delayed.
What size cooler can I bring on board Carnival?
Carnival permits carry-on coolers up to 12" x 12" x 12" for medical use. Standard insulin travel coolers (Frio-style, MedActiv, or generic 48-hour soft coolers) fit well within this limit. Keep medical documentation handy in case the cooler is inspected at embarkation.
What if my Carnival cruise visits an international port like Cozumel or Cancun?
You typically stay onboard with your medication; only items disembarked into port need to clear local customs. If you do plan to leave the ship with vials or syringes, treat it like a Mexican customs entry: labeled medication, prescription on hand, personal-use quantities only. See our Cancun customs guide for the red/green button system.
How do I keep peptides cold during embarkation if I arrive hours early?
Use a 48-hour insulated cooler with frozen gel packs — this covers the full embarkation-day wait at the terminal plus the time before your cabin is ready. Once in your cabin, transfer vials to the Carnival-issued medi-cooler or Medical Center storage. The 48-hour cooler also serves as backup if the medi-cooler runs out of stock.
