Essential Guide: Medical Medication Import Rules and Preparation for Hawaii Travel
Hawaii is a popular destination for Japanese travelers, but the United States has strict regulations on importing prescription and over-the-counter medications. If you require chronic disease treatment medications or want to bring over-the-counter remedies, special attention is necessary. This article, written from a pharmacist's perspective, clearly explains Hawaii's import rules, prohibited substances, and required documentation.
Basic Rules for Importing Medications to Hawaii (USA)
Core Principles for Prescription Drug Import
The importation of medical medications to the United States is strictly limited to personal medical use during overseas travel. Three key points are essential:
- For personal use only: Using or giving medications to others is strictly prohibited
- Limited quantity (approximately 3 months' supply): Large quantities are considered violations
- Physician's prescription and English-language medical certificate are mandatory: Especially when the container does not display the physician's name
Under the regulations of U.S. Customs and Border Protection (CBP) and the Food and Drug Administration (FDA), violations can result in confiscation, fines, and even U.S. entry denial.
Pharmacist's note
Hawaii is a U.S. state, so Japan's "medication import permit system" does not apply. Determinations are made according to FDA standards. Customs inspections at Honolulu International Airport are relatively strict.
Main Medications and Substances Prohibited or Restricted
The following table highlights substances and medications requiring particular attention when traveling to Hawaii:
| Medication/Substance | Classification | Reason/Countermeasure |
|---|---|---|
| Narcotic pain relievers (codeine, oxycodone, etc.) | Prohibited | Regulated under U.S. Controlled Substances Act |
| Psychotropic drugs (some anti-anxiety medications) | Requires medical certificate | Substances like tramadol and phenytoin require advance declaration |
| Herbal remedies (products containing ephedra) | Restricted | Ephedra and ephedrine are prohibited |
| Prescription eye drops (containing strong antibiotics) | Requires prescription copy | Difficult-to-obtain medications may be permitted |
| Prescription medications (general) | Requires English medical certificate | Physician must provide proof of "medical treatment purpose" |
| Cold medicines and nutritional drinks (OTC products) | Permitted to import | Multiple units OK if for normal use |
Pharmacist's note
Japanese "Category 2 OTC medications" such as nutritional drinks (for nutritional supplementation) may be classified as "food" in the U.S. However, importing large quantities may raise suspicion from inspection officers, so bring only what you need.
Pre-Departure Preparation: Required Documents
How to Obtain English Medical Certificates (English Prescriptions)
This is mandatory if you plan to import prescription medications.
| Document | Issuing Source | Contents | Approximate Cost |
|---|---|---|---|
| English prescription | Prescribing physician | Drug name (brand and generic), dosage, instructions, prescription date | ¥1,000–¥3,000 |
| English medical certificate | Prescribing physician | Diagnosis, medical necessity, dosage, patient name and date of birth | ¥2,000–¥5,000 |
| Copy of original prescription | Pharmacy | Original with physician's signature | Free–¥500 |
Steps to obtain documents:
- Inform your physician of your Hawaii travel plans 1–2 weeks before departure
- Explicitly request "English prescription and medical certificate"
- Prepare two copies each of the original and copied English documents
- When picking up medication at the pharmacy, inform them "an English medical certificate is needed"
Key points for document content:
- Full patient name (matching passport name)
- Date of birth
- Physician signature and medical facility stamp
- Ideally include the statement "For personal use during travel to Hawaii"
Pre-Departure Document Checklist
□ English prescription (1 original, 1 copy)
□ English medical certificate (1 original, 1 copy)
□ Original medication containers (with visible labels and physician name)
□ Passport
□ Contact information for prescribing medical facility (preferably English-speaking)

Pharmacist's note
English medical certificates can be obtained even through online consultations. If obtaining the certificate close to your departure date, contact your physician in advance via email.
Purchasing Over-the-Counter Medications in Hawaii
Available Pharmacies and Medications
In Hawaii, over-the-counter medications can be purchased at CVS Pharmacy, Walgreens, Long's Drug Stores, and similar retailers.
| Medication Category | Availability in Hawaii | Japanese Equivalent |
|---|---|---|
| Fever and pain relievers | ★★★★★ | Acetaminophen (Tylenol) = Lulu acetaminophen |
| Gastrointestinal regulators | ★★★☆☆ | Imodium (loperamide) = Seirogan |
| Antihistamines | ★★★★★ | Benadryl (diphenhydramine) = Class 1 OTC medication |
| Nasal decongestants | ★★★★☆ | Sudafed (phenylephrine) = Kakkon-to |
| Antacids | ★★★★☆ | Tums (calcium carbonate) = Ohta's Isan |
| Laxatives | ★★★☆☆ | MiraLAX (polyethylene glycol) = Magnesium oxide |
Important points when purchasing:
- Inform pharmacy staff "I'm from Japan" and confirm dosage and instructions
- Verify ingredient labels (ensure they are not prescription-strength)
- Limit purchases to over-the-counter medications only
- Both credit cards and cash are accepted (tipping is not required)
Essential Over-the-Counter Medications to Bring from Japan
Beyond prescription medications, consider bringing these over-the-counter remedies from Japan:
| Medication | Quantity | Reason |
|---|---|---|
| Comprehensive cold medicine (Lulu, Benzablock, etc.) | 1–2 boxes | For unexpected colds during travel |
| Gastrointestinal regulator (Biofermin, Ebios, etc.) | 1 bottle | For digestive issues from water changes |
| Topical ointments (Mentholatum, Oronine, etc.) | 1–2 tubes | For insect bite itching |
| Patches (Loxonin, etc.) | 1–2 patches | For muscle soreness and sunburn pain |
| Regular supplements/vitamins | Double your normal amount | To accommodate time zone and meal changes |
Pharmacist's note
One or two boxes of "Category 2 OTC cold medicines" are permitted for import. Over-the-counter medicines purchased without a prescription in Japan are also recognized in the U.S. as "self-treatment OTC medications," and present no problem if quantities are reasonable.
Airport Inspection Procedures and How to Respond
Customs Inspection at Departure Airports (Narita, Kansai, etc.)
Japanese customs is relatively lenient regarding medication imports.
- Medications are typically classified as "medical supplies" and subject to declaration
- If you have an English medical certificate, they usually determine "no problem"
- Medication containers typically pass X-ray screening without issue
Key response points:
- Keep all medications in a separate pouch
- Mark "medications included" on the customs declaration form
- If asked, show your English medical certificate
Honolulu International Airport Inspection (Critical!)
U.S. customs inspection is more rigorous. Prepare the following:
| Situation | Response |
|---|---|
| Pre-inspection (customs check) | Consolidate medications in one container and attach a label stating "Medicine for personal use" |
| When questioned by medication inspector | Immediately present English medical certificate and prescription; explain calmly in simple English |
| For prescription medications | Briefly state "Doctor prescribed for my condition" |
| If confiscation is likely | Do not protest; accept the decision. Keep backup copies of important medications |
English explanation example:
"These medicines are prescribed by my doctor in Japan.
I have a medical certificate and prescription in English.
This is for my personal use during my stay in Hawaii."
Pharmacist's note
CBP officers at Honolulu International Airport may have limited knowledge of medications. Repeatedly emphasizing "prescription medication," "doctor's orders," and "personal use" is important. Stay calm, polite, and patient.
