Traveling with medication goes smoothly with a little planning. Pack medicines in your carry-on, keep them in their original labeled containers, bring enough for the whole trip plus extra for delays, and carry copies of your prescriptions. For trips abroad, check the rules for every country on your route, including layovers, before you go.
This is general information, not medical advice. Talk to your doctor or pharmacist about your own situation.
This is an example checklist based on CDC travel advice, not an official list. Add anything your doctor or pharmacist suggests.
Enough medicine for the whole trip, plus extra in case of travel delays (CDC).
Original, labeled containers. The CDC says labels should show your full name, your health care provider's name, the generic and brand name, and the exact dosage.
Copies of all written prescriptions, including generic names, plus prescriptions for glasses or medical supplies. Leave another copy with a friend or relative at home.
A doctor's note if you use controlled substances or injectable medicines such as EpiPens or insulin (CDC).
Contact details for your health care professionals at home and a family member or close contact.
Health insurance card and any travel insurance documents.
Medical alert bracelet or necklace, if you use one.
Over-the-counter basics you might need on the trip, since some items may be hard to find where you're going.
The CDC suggests keeping both a printed and a digital version of each document with you during the trip if you can.
Pack medicine in your carry-on. The CDC recommends it in case your checked luggage is lost or delayed.
Tell the officer. TSA asks you to inform the officer that you have medically necessary liquids or medications before screening begins.
Liquid medicines. TSA allows medically necessary liquids, gels and aerosols in reasonable quantities, but you must declare them at the checkpoint for inspection. They don't have to go in a zip-top bag. They may need extra screening.
Pills and other solid medicines are allowed but must go through screening.
Label clearly. TSA recommends that medication be clearly labeled to make screening easier, and says to check state laws on prescription labels.
Accessories. Declare items such as freezer packs, pumps and syringes too.
Don't want it X-rayed? TSA says to tell the officer if you don't want liquid medication X-rayed or opened. An FDA pharmacist video on travel adds that you can ask for an inspection instead of an X-ray for other medication too.
The CDC warns that each country has its own laws on medicines. A medicine that's common or even sold over the counter in the United States may be unlicensed or treated as a controlled substance elsewhere. Breaking those laws can mean having your medicine taken away, or penalties that include jail or prison time.
Check with the embassy of your destination and of any country where you have a layover.
Expect paperwork. The CDC says many countries allow a 30-day supply of certain medicines but require you to carry a prescription or a medical certificate from your provider.
Plan for banned medicines. If a medicine isn't allowed, talk with your provider about alternatives and ask for a letter describing your condition and treatment plan.
See your provider early. The CDC suggests a visit with your provider or a travel health specialist at least 4 to 6 weeks before you leave.
Coming home to the United States. In the same FDA video, FDA pharmacists summarized U.S. Customs and Border Protection (CBP) advice: keep medicines in their original containers, bring only personal-use quantities (their rule of thumb is no more than a 90-day supply), and carry a copy of the prescription or a doctor's letter for anything not in its original container. Rules can change, so check CBP's current guidance before you travel.
The CDC advises asking your health care provider about any changes to how you take your medicine before you travel to a different time zone. It also notes that medicines should be taken according to the time since your last dose, not the local time of day.
What that means in practice depends on each medicine, so ask your pharmacist to help you write out a travel schedule for each one. Don't work out new timings on your own. If you do miss a dose on the road, our sister site's guide on what to do if you miss a dose covers safe first steps.
Long trips. If you'll be gone more than 30 days, talk to your provider about getting enough medicine. The CDC notes some insurance companies only pay for a 30-day supply at a time.
Lost prescriptions. The copy you left with someone at home helps if you lose yours or need an emergency refill.
Buying medicine abroad. The CDC says counterfeit drugs are common in some countries, so use only medicine you bring from home. If you must buy medicine in an emergency, the CDC has a page on counterfeit drugs worth reading first.
Storage. Find out whether your medicine needs refrigeration. The CDC notes extreme temperatures can reduce the effectiveness of many medicines.
Call before the trip if you're unsure how to time doses, whether a medicine is allowed abroad, or how to store it. During the trip, contact your provider or a local pharmacist if you lose medicine, run low or feel unwell after a change in routine. The CDC suggests packing a list of hospitals or clinics, including emergency services, for each destination. In an emergency, call the local emergency number, which is 911 in the United States.
TSA recommends that medication be clearly labeled to make screening easier, and it says to check state laws on prescription medication labels. For international trips, the CDC advises keeping medicines in their original, labeled containers.
Yes. TSA allows medically necessary liquids in reasonable quantities if you declare them at the checkpoint. They may need extra screening.
The CDC recommends your carry-on, so your medicine isn't lost or delayed with a checked bag.
It depends on the country. Many allow a 30-day supply of certain medicines with a prescription or medical certificate, so check with the embassy for each country on your route.
