ChronoPillTraveling to the United States with medication
The United States schedules controlled substances at the federal level, and several medications that are unscheduled internationally are nonetheless controlled there. Its declared rules for travellers carrying controlled medicines are filed with the INCB. Here is the context worth knowing, and who can give you a definitive answer.
Read the filing (PDF)
United States's own declared rules for travellers carrying controlled medicines, including carry limits and required documents, live in its official INCB filing (17 June 2014): read the filing (PDF). This page summarizes context around it; the filing and the national authorities it names are authoritative.
Substances worth checking before you pack
The table below combines two sources: the INCB international lists (which substances are controlled under the UN conventions) and ChronoPill's in-app travel reference (what it notes for the United States). It is a starting point for a conversation with your pharmacist, not a ruling.

Checklist for the United States
- Know the active substance (INN) of each medication; US pharmacies may know your brand under a different name.
- Read the United States' official INCB filing (linked above) for its declared rules on travellers with controlled medicines.
- Carry your prescription for any controlled medication, in original packaging.
- If a medication is federally scheduled (for example ADHD stimulants), ask your pharmacist and the nearest US embassy or consulate what documentation applies to your situation.
- Remember that some rules vary by state; the in-app reference notes this for CBD products.
- For any doubt, contact a US embassy or consulate before departure.
How ChronoPill's Travel Mode helps
ChronoPill bundles the official medication databases of 7 countries (including the United States) on your iPhone: 500,000+ records, fully offline. When you set a destination, Travel Mode:
- Flags medications in your list whose active substance is internationally controlled, and names the substance
- Maps each medication to its local equivalent by active substance (INN), with the destination-language name
- Generates a pharmacist card you can hand over at any counter abroad
- Shifts your dose schedule to the destination time zone automatically
Travel alerts are informative only: they tell you which substance to verify and with whom (your pharmacist, the destination's consulate). They never tell you to skip a dose or leave a medication behind.
Frequently asked questions
Can I bring my prescription medication into the United States?
The United States' declared rules for travellers carrying controlled medicines are in its official INCB filing (17 June 2014), linked on this page. Personal medication imports are governed by US federal rules, and several substances are federally scheduled even when they are not internationally controlled.
For a definitive answer on your specific medication and quantity, ask your pharmacist to identify the active substances and confirm with a US embassy or consulate before travel.
Is tramadol controlled in the United States?
Tramadol appears on none of the INCB international lists, but ChronoPill's travel reference notes it as a US federal Schedule IV controlled substance since 2014. It is a good example of why the international lists alone are not enough: national schedules can be stricter.
If you travel with tramadol, carry your prescription and confirm current requirements with a US embassy or consulate.
Are ADHD medications like methylphenidate allowed?
Methylphenidate and amphetamine-class medications are internationally scheduled (INCB Green List), and ChronoPill's travel reference notes both as US federal Schedule II. Schedule II is the strictest schedule that still allows medical use.
Travelers using these medications should carry their prescription and verify current documentation requirements with a US embassy or consulate and their pharmacist before departure.
Is pseudoephedrine restricted in the United States?
Pseudoephedrine is a 1988 Convention precursor (INCB Red List). ChronoPill's travel reference notes that in the US it is sold behind the pharmacy counter with ID checks and quantity limits under the Combat Methamphetamine Epidemic Act, rather than banned.
If a cold remedy matters to your trip, ask a pharmacist how the rules apply to your quantities.
