When you're flying and need to bring your medicines, the TSA medication rules, the official guidelines from the U.S. Transportation Security Administration for carrying drugs on commercial flights.

You don’t need to keep your meds in their original bottles, but it helps. The TSA doesn’t require it, but having the prescription label makes things easier if an officer asks. Think of it like showing your ID: not mandatory, but smart. If you’re carrying liquid meds over 3.4 ounces (like insulin or liquid antibiotics), you’re allowed to bring them in your carry-on. You don’t have to put them in the quart-sized bag for liquids, but you must tell the officer at the checkpoint. Same goes for syringes or auto-injectors like EpiPens—declare them, and they’ll screen them separately. No need to panic. These are common items, and TSA agents see them every day.

Just make sure you have the prescription, and if you’re carrying a large supply (like a 90-day supply), keep a letter from your doctor explaining why you need it. TSA doesn’t arrest people for having legal prescriptions, but they do flag suspicious amounts. If you’re switching to a generic version, like authorized generics, brand-name drugs sold under the original manufacturer’s approval at a lower price. Also known as generic equivalents, they’re chemically identical to the brand.—that’s fine too. No extra paperwork needed.
Don’t forget your vitamins and supplements. They’re allowed, but if you’re carrying a huge bottle of melatonin or CBD oil, be ready to explain. CBD is legal federally if it’s hemp-derived and under 0.3% THC, but some states and countries still treat it like marijuana. Stick to the basics: label it, pack it in your carry-on, and don’t overdo it.
