Bringing Medication to the USA: Complete Guide for Prescription and OTC Drugs
Reports frequently document travelers being detained at US airports due to unfamiliarity with medication import rules. What is a standard over-the-counter medication in Japan may be classified as a controlled substance in the United States. This article provides practical guidance based on the latest US FDA (Food and Drug Administration) regulations, explained by a licensed pharmacist with a doctorate in pharmaceutical sciences.
Basic US Medication Import Rules
Personal Use: Up to 90 Days' Supply Allowed
According to US regulations, you may bring up to 90 days' worth of medication for your own medical use, provided the following conditions are met:
- Prescription medications must be in original containers with clear labeling
- Over-the-counter medications must have their intended use clearly identifiable
- Medical records or prescriptions strengthen credibility
Pharmacist's note The "90-day" guideline is approximate. The TSA (US Transportation Security Administration) uses "medically reasonable quantity" as the standard. For example, if you normally take 30 tablets per month, interpreting 90 days as 2,700 tablets should be avoided. Pack medication within commonsense limits.
Carry-On vs. Checked Baggage
| Baggage Type | Rule | Recommendation |
|---|---|---|
| Carry-on (cabin) | Allowed if containers are clearly labeled | ★★★ Recommended |
| Checked baggage | Same rules, but difficult to access | ★ Not recommended |
| Liquid/gel medications | Subject to 100ml liquid limit | Confirmation required |
Recommendation: Pack medications in carry-on luggage. If checked baggage is delayed or lost, obtaining replacement medication locally becomes difficult. Liquid eye drops or cold remedy syrups are permitted in carry-on if 100ml or less, allowing passage through security screening.
Watch Out: Medications Restricted in the USA
Banned and Restricted Medication Components
| Japanese Medication | Active Component | US Status | Reason |
|---|---|---|---|
| Loxonin (loxoprofen) | Loxoprofen | ❌ Banned | Not FDA-approved analgesic |
| Benzablock | Phenylephrine | ⚠️ Restricted | Questionable efficacy as OTC |
| Mentholatum Cream | Menthol | ✅ Allowed | Limited to natural-source derivatives |
| Seirogan (Seirogan) | Creosote | ❌ Banned | Designated toxic substance |
| Estak | Multi-symptom cold remedy | ⚠️ Restricted | Contains unapproved components |
| Yunkel (Yunker) | Vitamin-enriched supplement | ✅ Allowed | Treated as dietary supplement |
| Akagire Ointment | Heparin-like substances | ⚠️ Restricted | Equivalent to prescription medication |
Pharmacist's note The ban on Seirogan (containing creosote) surprises many travelers, but creosote is designated as a toxic substance in the US. Alternatives include Imodium AD (loperamide) or Pepto-Bismol (bismuth subsalicylate), both available OTC. For Loxonin, aspirin or ibuprofen (Advil) serve as effective substitutes.
Prescription Components Requiring Special Attention
The following prescription components are also regulated in the US:
- Anti-anxiety medications (e.g., alprazolam, lorazepam): DEA controlled substances
- Sleep aids (e.g., zopiclone): mandatory declaration upon entry
- Stimulant medications (e.g., phenytoin-containing drugs): liquid form restrictions
- Cough suppressants (codeine-containing): banned in some states
Essential Documents for Bringing Prescription Medications
Physician's Prescription and English Medical Certificate
When entering the USA, having one of the following documents provides assurance:
1. English-Language Prescription
- Obtained from a Japanese physician (typical cost: ¥1,000–¥3,000)
- Physician's signature and stamp required
- Medical facility contact information included
2. English Medical Certificate
- More detailed: medication name, dosage, duration of use
- Can use Foreign Ministry "Certificate Request" template
3. Letter from Dispensing Pharmacist
- Last resort: some pharmacies will prepare one
- Include generic name and active component on A4 paper
Pharmacist's note Request physician documentation at least 2 weeks before departure. Many medical facilities cannot accommodate rush requests. Clearly communicate to your physician that you need documentation for medication import. Standard prescription formats may prove insufficient.
International Standards Recognized as Safe
The International Air Transport Association (IATA) provides the following criteria:
- Medical justification: Is the medication for a condition documented in your medical records?
- Appropriate dosage: Does the quantity match your prescribed dose?
- Container labeling: Are the medical facility name, patient name, and dosage clearly marked?
Accepted OTC Medication Examples: Actually Approved
Japanese OTC Drugs with Equivalent US Products
The following Japanese over-the-counter medications have readily available US equivalents and are generally approved for import:
| Japanese OTC | US Equivalent | Where to Buy |
|---|---|---|
| Bufferin | Aspirin | CVS, Walgreens, Amazon |
| Gaster 10 | Pepcid AC (famotidine) | Pharmacies, supermarkets |
| Pabron Gold | Theraflu (multi-symptom cold remedy) | Pharmacies |
| Shin Restamin | Benadryl (diphenhydramine) | Pharmacies, convenience stores |
| Muhi Sting Relief Cream | Hydrocortisone Cream | Pharmacies |
| Eye drops (OTC category) | Clear Eyes, Visine | Supermarkets, pharmacies |
Advice: These are easily purchased in the US, so importing them from Japan is often unnecessary. Consider local purchase to reduce luggage weight and minimize import risk.
Import Checklist and Practical Procedures
Pre-Departure Preparation Checklist
☐ Obtain English-language prescription/medical certificate from physician
☐ Keep medications in original containers with readable labels
☐ Adjust quantity to approximately 90 days' supply
☐ Prepare handwritten list of medications to bring
☐ Note medical facility English address and contact information
☐ Ensure liquid medications are in containers 100ml or smaller (or pack in checked baggage)

Airport Security Screening Procedures
How to declare medications during hand-baggage screening:
-
Declare before X-ray screening
- Tell the officer: "I have prescription medications"
- Place medications in a separate bag away from other items
-
Present physician's letter/prescription
- Show the English medical certificate to the officer
- Ensure the physician's signature is visible
-
Explain your medications
- State simply: "I take this medicine for [disease name]"
- Be prepared to explain dosage and duration
Pharmacist's note Voluntarily disclosing that you are carrying prescription medication creates a favorable impression with security. Medications discovered when concealed carry higher confiscation risk than those voluntarily declared.
