Taking ADHD medication to the United States

The United States regulates all stimulant ADHD medications, including amphetamine/dextroamphetamine (Adderall, Adderall XR, Mydayis), lisdexamfetamine (Vyvanse), methylphenidate (Ritalin, Concerta, Daytrana), and dexmethylphenidate (Focalin), as Schedule II controlled substances under the Controlled Substances Act^[1].

Non-stimulants in the class, atomoxetine (Strattera), guanfacine (Intuniv, Tenex), and clonidine (Kapvay, Catapres), carry no DEA scheduling and follow standard prescription rules.

Schedule II stimulants require a written or electronic prescription from a DEA-registered prescriber and cannot be refilled under federal law^[2]. Each prescription is limited to a 30-day supply. Regional supply shortages for amphetamine-based medications have persisted since 2022 and were still being tracked by the FDA into 2026, so confirming pharmacy stock in advance is advisable.

Medical disclaimer: This guide is for informational purposes only and does not constitute medical advice. Always consult your prescribing doctor before travelling with medication, particularly regarding supply quantities, storage requirements, and import documentation.

Before you travel

Documentation for travelling to the United States with ADHD medication

The most important document for stimulant ADHD medications is your original pharmacy-labelled container. U.S. Customs and Border Protection (CBP) requires that all prescription medications are declared on entry^[3], and CBP officers can inspect the label to confirm the medication belongs to you. Carry a doctor's letter as a supplement, the U.S. State Department recommends a letter naming each medication by generic and brand name^[4], including dose and prescribing doctor details.

If you take only a non-stimulant, such as atomoxetine, guanfacine, or clonidine, the documentation pathway is simpler. Your original prescription or pharmacy label is typically sufficient, though a doctor's letter is still recommended. Keep medications in their original containers with the pharmacy label intact^[3] at all times, decanting into a pill organiser before crossing the border creates identification problems. For a more comprehensive preparation checklist, refer to our guide on travelling abroad with ADHD medication.

How much ADHD medication to bring

Federal law limits each Schedule II prescription to a 30-day supply with no refills, so bring enough stimulant medication to cover your entire stay plus a buffer^[2]. Non-stimulants such as atomoxetine, guanfacine, and clonidine can be dispensed in up to 90-day quantities by a U.S. prescriber, but obtaining a local refill still requires a consultation. Add at least five extra days to your planned supply to account for flight delays or itinerary changes. Obtaining a new Schedule II prescription from a U.S. psychiatrist is possible but requires an in-person evaluation and cannot be guaranteed quickly.

Packing and storing ADHD medication for travel

All oral ADHD medications in this class, including stimulants and non-stimulants, are stored at room temperature between 15°C and 30°C (59°F and 86°F) and do not require refrigeration. Keep them away from moisture, heat, and direct light. The Daytrana methylphenidate patch should be stored at room temperature and kept in its sealed tray until use. Do not transfer any tablets or capsules into a plain container before your flight, as unlabelled medications attract additional scrutiny at security and at the border.

At the airport and border

Airport security with ADHD medication

The U.S. Transportation Security Administration (TSA) permits medication in pill or solid form in both carry-on and checked baggage. You do not need to declare solid tablets or capsules to a TSA officer unless they are in liquid form. The TSA recommends keeping prescription medication in carry-on luggage so it remains accessible and is not lost with checked bags. If you prefer not to have your medication X-rayed, request a visual inspection before placing your bag on the belt.

Customs and import rules for ADHD medication in the United States

All travellers entering the United States must declare all prescription medications to U.S. Customs and Border Protection^[3]. CBP uses the CBP One app or paper Form 6059B for declarations. For Schedule II stimulants brought across an international land border by a traveller who holds a valid DEA-registered prescription, more than 50 dosage units may be imported.

Without a prescription from a DEA-registered prescriber, no more than 50 dosage units of a controlled substance may be imported^[5]. CBP officers may ask follow-up questions and review your packaging and prescription documentation.

While in country

ADHD medication availability in the United States

Every active ingredient in this class is approved and available in the United States. Amphetamine/dextroamphetamine is sold as Adderall IR, Adderall XR, and Mydayis, with generics widely stocked. Lisdexamfetamine is sold as Vyvanse, and a generic lisdexamfetamine became available following FDA approval in 2023^[6].

Methylphenidate appears as Ritalin, Ritalin LA, Concerta, Metadate, Methylin, Quillivant XR, and the Daytrana patch, plus a large range of generics. Dexmethylphenidate is sold as Focalin and Focalin XR, with generics available.

Non-stimulants are reliably available. Atomoxetine is sold as Strattera and as generic atomoxetine. Guanfacine is sold in extended-release form as Intuniv and immediate-release as Tenex, both with generics. Clonidine is available as Catapres, Kapvay, and Duraclon, plus generics at most pharmacies.

Regional shortages of amphetamine-based ADHD medications have persisted since 2022 and were tracked by the FDA as active shortages into 2026^[7]. If one pharmacy is out of stock, call ahead to others or ask the pharmacist to check alternative suppliers before concluding the medication is unavailable in your area.

Without insurance, costs vary considerably by active ingredient and formulation. Generic amphetamine salts (Adderall equivalent) typically cost $60 to $130 per month at retail pharmacies without insurance^[8] (~€52 to ~€112). Brand-name Adderall XR runs approximately $300 to $450 per month (~€259 to ~€389). Brand-name Vyvanse costs around $555 per month (~€479), while generic lisdexamfetamine averages around $323 per month (~€279). Generic methylphenidate costs approximately $30 to $80 per month (~€26 to ~€69). Non-stimulants range from approximately $30 to $200 per month for generics, depending on the active ingredient and dose.

Pharmacy phrases for the United States

English is used at all U.S. pharmacy counters. These phrases will help you confirm stock and discuss your prescription.

Finding a doctor who can prescribe ADHD medication in the United States

Psychiatrists are the primary specialists for ADHD in the United States. General practitioners and paediatricians can also prescribe stimulants but must hold DEA registration. An initial in-person evaluation is typically required before a new Schedule II prescription is issued, though telehealth rules for controlled substances have been evolving since 2024.

Consultation fees vary widely: a private psychiatrist consultation without insurance costs approximately $200 to $400 (~€173 to ~€346) for an initial appointment. Use Nomedic's provider search to find doctors and pharmacies near your destination.

Storing ADHD medication while in the United States

All oral ADHD medications in this class are stable at room temperature and do not require refrigeration during storage. Keep your supply in a cool, dry place away from direct sunlight. Hotel room safes are a practical option for securing Schedule II controlled substances. If you are visiting areas with extreme summer heat, such as the Southwest or Southern states, avoid leaving medication in a parked car where temperatures can exceed safe storage limits rapidly. The Daytrana patch should remain in its sealed tray until immediately before use.

Emergencies

What to do if something goes wrong with your ADHD medication in the United States

If your stimulant medication is lost or stolen, file a police report immediately and keep a copy. Schedule II prescriptions cannot be refilled^[2], so a new prescription requires a face-to-face appointment with a DEA-registered prescriber. Contact your home prescriber by phone or video to request clinical notes that a U.S. psychiatrist can use to issue a new prescription. A handful of states permit a pharmacist to dispense a 72-hour emergency supply of a Schedule II medication in genuine emergencies, but this is not universally available and varies by state law.

If your specific brand is out of stock, ask your pharmacist whether a generic of the same active ingredient is available, and confirm with them whether your prescription can be filled with the generic. Never substitute one active ingredient for another without a prescriber's involvement. A U.S. psychiatrist can review your history and suggest whether a different active ingredient in the same class is appropriate, that decision belongs to a clinician. Keeping your medication details in your IPS on Nomedic means any U.S. doctor can see your current prescription at a glance.

For any medical emergency in the United States, call 911. Emergency departments at hospitals are open 24 hours and cannot refuse to see a patient in a medical crisis. Urgent care clinics are available across the country for non-emergency situations and can typically be found within a short distance in any urban or suburban area.
