Flying With Medication and Medical Devices

This page summarizes published TSA guidance for travelers. It is not medical or legal advice, individual checkpoints and countries differ, and a screening officer has the final say. The authoritative sources are linked at the bottom.

The exemption, exactly as published

Most people packing medication squeeze it into the quart bag alongside their shampoo, and lose most of a very small allowance doing it. That is not what the rule requires.

The declaration is the whole price of the exemption, and it is one sentence said before your bag goes on the belt rather than after it is pulled. How the ordinary 3-1-1 rule works.

Pills are simpler than people expect

Solid medication — tablets, capsules, vitamins and supplements — is not a liquid and the liquids rule does not touch it. There is no published federal quantity limit and no federal requirement that it stay in the original prescription container.

That said, clear labeling helps for a practical reason rather than a legal one: an officer with a question about an unlabeled bottle takes longer to resolve it than an officer looking at a pharmacy label. Keeping the original container, or a photograph of the label, costs nothing and removes the conversation.

Individual states and other countries have their own rules on carrying prescription medication, and those are a different question from airport screening. Check the destination if you are carrying anything controlled.

Where medication must be packed

This is not a screening rule. It is a consequence of how baggage actually behaves, and it is the most important paragraph on the page.

• Medication travels in the cabin, always. A checked bag can be delayed for days, and the medication you need is on the wrong continent. How often that happens, and what to do.
• In the bag that stays with you — the personal item under the seat, not the carry-on that might be taken at the door. A gate-checked bag is a checked bag.
• Split a long trip’s supply across two bags if you are traveling with someone. Half each means a lost bag is an inconvenience.
• Carry more than the trip needs. Delays happen and pharmacies abroad are a project. A few extra days of supply weighs nothing.
• In its own pouch, so you can hand the whole thing to an officer rather than excavating a bag on a bench.

Medical devices

Devices are screened, and the TSA publishes modified procedures for passengers with disabilities and medical conditions through its TSA Cares program. Some general points worth knowing before you get to the front of the queue:

1. Tell the officer at the start of screening, not when something is flagged. This is the same principle as declaring liquids and it works the same way.
2. Devices generally do not count against your carry-on allowance. Most carriers publish that assistive and medical devices are carried in addition to your normal baggage — check your carrier’s own published policy.
3. Anything with a lithium battery follows the battery rules, which means the cabin rather than the hold. The 100 Wh threshold and the spare-battery rule.
4. Bring the charger and a way to power it. Seat power is not guaranteed and a delay is exactly when a device runs flat.
5. Contact TSA Cares in advance for anything complex. It exists for precisely this and it is the difference between a planned screening and an improvised one.

If it has to stay cold

Ice packs, freezer packs and gel packs needed to keep medically necessary items cool are permitted, and they fall under the same declaration requirement as the medication itself. They are screened, and they may be inspected more closely if they have partially melted.

Practical note rather than a rule: a cabin is cold and dry, and a hold is neither reliably. Anything temperature-sensitive is another reason the medication never goes below.
