Travelling With GLP-1 Medication

Getting through security

• Medication is exempt from the liquid volume limits. So are the cold packs, gel packs and freezer packs needed to keep it cool.
• Declare it at the checkpoint. Tell the officer you have medication and cooling packs before screening starts. It takes seconds and avoids a conversation later.
• Keep it in the original packaging with the pharmacy label showing your name. This is the single most useful thing you can do.
• Bring your syringes or pen needles in the same bag as the medication. Screening is used to this.
• Cold packs may be inspected — they can be frozen solid, partially thawed, or slush. All are permitted.
• You do not legally need a doctor's letter for domestic US travel, but one costs nothing and removes any argument. Ask your provider.

Keeping it cold

Time zones and your injection day

This is the most-asked question and the answer is reassuring: it does not matter much. These medications have a half-life of about a week. A shift of several hours is irrelevant to a seven-day cycle.

1. Short trips — keep your usual day and inject at whatever local time is convenient.
2. Long-haul, staying a while — inject on your usual day at a sensible local time, and let that become your new time.
3. Crossing the date line — pick the calendar day that keeps you closest to seven days between doses and carry on.
4. If it drifts by a day or two, that is fine. Re-anchor to a consistent day once you are settled — see GLP-1 Dosing and Titration, Week by Week.

Before you leave

• Bring more than you need. One extra dose, minimum. Delays happen.
• Check your delivery schedule against your travel dates so a shipment does not arrive at an empty house — heat on a doorstep ruins medication.
• Photograph your prescription label. Useful if anything is lost or questioned.
• Pack a sharps solution. A small travel sharps container, or plan to bring used needles home in a hard container. Do not put loose needles in hotel bins.
• Take extra electrolytes. Travel plus reduced appetite plus dry cabin air dehydrates efficiently — see Managing GLP-1 Side Effects.

International travel

Rules vary by country and some have strict rules about carrying prescription medication. A few sensible precautions: carry the original labelled packaging, bring a letter from your prescriber stating what it is and that it is for personal use, and check the destination country's rules before you fly. For most common destinations this is entirely routine.

Eating on the road

Reduced appetite plus airport food plus disrupted routine is a reliable way to miss your protein target for a week. A few things that travel well: shelf-stable protein shakes, jerky, tinned fish, nuts, protein bars you have actually tested. Long flights are also the classic setting for accidental dehydration — see Eating Well on a GLP-1, and Holidays, Restaurants and Eating Around Other People for eating around other people.
