How to Pack Medications for Travel: TSA Rules and a Checklist

Pack every medication you need for the trip, plus extra for delays, in your carry-on bag, not your checked luggage [S01][S06]. Pills and other solid medications can go through airport security in any amount once screened [S01]. Liquid medications larger than 3.4 ounces (100 mL) are allowed in reasonable quantities, but you must tell the TSA officer at the start of screening and take them out of your bag [S01][S02]. Keep medicines in their original labeled containers, bring copies of your prescriptions, and check how each one needs to be stored before you leave [S06].

Start with a complete medication list

Before you pack anything, write down every medication you take, including over-the-counter medicines and supplements. For each one, note:

• The brand and generic name.
• The dose and when you take it.
• Who prescribed it, with their phone number.
• How it is stored: room temperature, refrigerated or protected from light.
• How many doses you need for the trip.

CDC recommends bringing copies of all written prescriptions, including generic names, and leaving a copy with a friend or relative at home in case you lose yours or need an emergency refill [S06]. A list on paper also helps a hospital pharmacy or an urgent care clinic if something goes wrong on the road.

If you are traveling for treatment, bring the list to your appointments too. The care team at the cancer center will want to see it. Our Appointment Logistics Planner has space for it alongside your appointment times.

How much to bring

Pack enough for the whole trip, plus extra in case of travel delays [S06]. Delays happen: flights get cancelled, appointments get rescheduled, and a stay sometimes runs longer than planned. Our guide to when travel plans change covers what to do when that happens.

For a long stay, plan refills ahead. CDC notes that some insurance companies only pay for a 30-day supply at a time, so if you will be away longer than that, ask your health care provider how to get enough medicine for the trip [S06]. Ask your pharmacy whether it can transfer a prescription to a pharmacy near the treatment center.

Pack medications in your carry-on

Keep all medications in the bag you carry with you. CDC advises packing medicines in a carry-on in case your luggage is lost or delayed [S06], and TSA strongly recommends carry-on bags in case you need immediate access [S01]. You can still pack medication in checked bags, but if that bag goes missing you may be without it for days [S01].

A few packing tips:

• Use one clear pouch for medications so they are easy to find and easy to screen.
• Keep a day's doses in an easy-to-reach pocket for the journey itself.
• If two people are traveling, consider splitting a backup supply between both carry-ons.

Airport security rules for medication

TSA rules for medication are clearer than many travelers expect.

Liquids

Medically necessary liquids do not need to go in the quart-size bag [S01]. Take them out and put them in a separate bin with any related supplies such as freezer packs, pumps or syringes [S02]. Officers may test the liquid, and may ask you to open the container. TSA says screening will never include placing anything into the medically necessary liquid [S02].

If you do not want medication X-rayed

You can ask for a visual inspection instead. You must make the request before your items go into the X-ray tunnel [S01]. For liquids, tell the officer if you do not want them X-rayed or opened. TSA will take other steps to clear the item, which can include extra screening for you and your carry-on [S02].

Devices worn on the body

Tell the officer about an insulin pump, glucose monitor or other medical device attached to your body before screening starts. You will not be asked to remove it, though it may get extra screening [S02].

Labels and prescription bottles

TSA does not require medication to be in prescription bottles, but some state laws set rules on how prescription medicine is labeled, and travelers must follow them [S01]. The simplest approach is to keep everything in the original pharmacy container. CDC also recommends original, labeled containers that show your full name, your provider's name, the generic and brand names, and the exact dose [S06].

Get help at the checkpoint

TSA Cares is a helpline for travelers with disabilities and medical conditions. You can call (855) 787-2227 or use the TSA Cares form. To request a Passenger Support Specialist to help you through screening, contact TSA Cares at least 72 hours before your flight [S05]. Airport wheelchair service is provided by your airline, not by TSA [S05].

Keeping medication at the right temperature

CDC notes that extreme temperatures can reduce the effectiveness of many medicines, and suggests finding out how to store each medicine while traveling and whether it needs refrigeration [S06].

Practical steps:

• Ask the pharmacist about storage for each medicine, and how long it can safely be out of the fridge.
• Never leave medication in a parked car, the trunk or checked luggage on a hot or cold day.
• Use a small insulated bag with ice packs for refrigerated medicines. TSA allows ice packs for medically necessary items in any state of freezing [S02].
• Check your lodging. Before you book, ask whether the room has a refrigerator you can use for medication. Our extended-stay hotel checklist covers other questions to ask before a longer stay.

Time zones and dose timing

If you are crossing time zones, ask your health care provider whether you need to change when you take your medicines. CDC advises that medicines be taken according to the time since your last dose, not the local time of day [S06]. Set phone alarms in your home time zone for the travel day if that helps you stay on track.

Traveling outside the United States

If your trip includes an international flight, check the rules before you go. Each country has its own laws on medicines, and some common U.S. medicines are restricted or treated as controlled substances elsewhere [S06]. CDC recommends checking with the embassy of your destination and of any country you connect through. Many countries allow a 30-day supply of certain medicines but require a prescription or a medical certificate [S06].

Ask your prescriber for a letter if you use controlled substances or injectable medicines such as EpiPens or insulin [S06].

A simple medication packing checklist

• Full medication list with names, doses, times and prescriber contacts
• Copies of prescriptions, with a copy left at home [S06]
• All medicines in original labeled containers [S06]
• Enough for the trip plus extra for delays [S06]
• Everything in your carry-on [S06]
• Liquids over 3.4 oz ready to declare at security [S01]
• Insulated bag and ice packs for refrigerated items
• Sharps, pumps or syringes packed with the medication
• Pharmacy near your lodging identified
• TSA Cares contacted at least 72 hours ahead, if you need help [S05]

If a caregiver is helping manage medications, write down who is responsible for packing, refills and dose reminders. The Caregiver Handoff Sheet keeps those tasks in one place. For the rest of the trip, see planning a cancer center visit and caregiver travel planning.
