Yes: carry-on, labeled, original containers - and per TSA, medically necessary liquids over 3.4 ounces are allowed; declare them and screen separately.
International is the homework zone: medicines ordinary at home (stimulants, codeine combos, some sleep and anxiety drugs) can be restricted or illegal elsewhere - the NHS pattern applies everywhere: check whether yours is a controlled drug, confirm the destination's rules with its embassy before travel, and carry proof - original packaging plus a prescription or doctor's letter. Extras: split double doses across two bags, photograph prescriptions, plan time-zone shifts for strict-schedule drugs with your pharmacist, and plan cold-chain for refrigerated meds.

What to do
Common questions
Can you travel with prescription medication?
Yes, and the rules are friendlier than people fear - with a few traps. Domestic US (TSA): medication rides in your carry-on, clearly labeled; medically necessary liquids, medications, and creams are allowed in quantities over 3.4 ounces - declare them and remove them for separate screening. The carry-on point is non-negotiable practice rather than law: checked bags get lost and cabins are where your doses belong. International is where the real homework lives: other countries set their own rules on what enters - and medicines perfectly ordinary at home (ADHD stimulants, codeine combinations, some sleep and anxiety drugs, pseudoephedrine in Japan, to name famous examples) can be restricted or flatly illegal elsewhere; the NHS advice for leaving the UK captures the universal pattern: ask whether your medicine is a controlled drug, check the destination country's rules with its embassy BEFORE travel, and carry proof it is yours - the original labeled packaging plus a prescription or a doctor's letter. Practical extras: pack double the doses in two separate bags, photograph your prescriptions, keep time zones in mind for strict-schedule drugs (ask your pharmacist how to shift safely), and refrigerate-sensitive meds (some insulins, some biologics) need a cooler plan.
