When planning a trip to Japan, packing your essential medications like Allegra (fexofenadine) requires more consideration than you might expect.
Japan maintains some of the strictest medication import regulations in the world, with rules that can catch even seasoned travelers off guard.
The good news? Yes, you can bring Allegra to Japan, but there are important conditions and limitations you need to understand before packing your suitcase.
These regulations aren’t designed to make travel difficult but rather stem from Japan’s careful approach to pharmaceutical control and public health.
Japan’s Ministry of Health, Labour and Welfare enforces these regulations to protect public health and prevent the importation of substances that are restricted or regulated differently than in other countries.
What might be an over-the-counter medication in your home country could be strictly controlled or even prohibited in Japan.
“Many travelers assume their regular medications will be permitted in any country, only to face confiscation at Japanese customs. Understanding the rules before you travel is essential.”
Understanding Medication Import Rules
Why Japan Strictly Regulates Medications
Japan’s pharmaceutical regulations differ significantly from those in Western countries for several key reasons:
- Different approval processes: Many medications common elsewhere haven’t undergone Japan’s specific approval procedures
- Cultural and medical philosophy differences: Japan’s approach to certain active ingredients and treatment methodologies can differ from Western medicine
- Historical concerns about drug abuse: Stricter controls on psychoactive and stimulant medications
- Protection of domestic pharmaceutical market: Regulations that favor medications approved through Japanese systems
For allergy sufferers relying on Allegra for relief, proper preparation before your trip is crucial. The last thing you want is to have your medication confiscated at customs or, worse, to face potential legal issues for unknowingly violating import regulations.
This guide will walk you through everything you need to know about bringing Allegra to Japan legally and hassle-free, ensuring you can enjoy your cherry blossom viewing or business trip without the interruption of allergy symptoms.
The Legal Status of Allegra in Japan
Allegra (fexofenadine) is generally legal to bring into Japan for personal use, but understanding the specific regulations can save you significant headaches at customs. Japan has strict pharmaceutical import laws that all travelers must navigate carefully.
Fexofenadine is Legal in Japan
The good news is that fexofenadine, the active ingredient in Allegra, is approved for use in Japan. Unlike some other common medications that contain prohibited substances, standard Allegra is considered legal and safe according to Japanese pharmaceutical regulations.
Different Rules for OTC vs. Prescription Allegra
The rules differ depending on whether your Allegra is:
- Over-the-counter (OTC) Allegra: You can bring up to a 2-month supply for personal use without special documentation.
- Prescription Allegra: Limited to a 1-month supply and requires proper documentation (prescription and doctor’s letter).
It’s crucial to understand which category your specific Allegra product falls under, as this determines both the quantity allowed and documentation required.
Availability in Japanese Pharmacies
If you’re concerned about running out, you’ll be relieved to know that fexofenadine is widely available in Japanese pharmacies. While the packaging will be different, the medication itself is the same.
Traveler Tip: Consider purchasing Allegra locally if you’re staying in Japan for an extended period rather than trying to bring large quantities from home.
Japanese Brand Names for Fexofenadine
When shopping in Japan, you won’t find “Allegra” on the shelves. Instead, look for these Japanese brand names that contain fexofenadine:
| Japanese Brand | Active Ingredient | Typical Strength |
|---|---|---|
| アレグラ (Aregura) | Fexofenadine | 60mg |
| アレジオン (Arejion) | Epinastine | Similar antihistamine |
| フェキソフェナジン (Fekisofenajin) | Fexofenadine | Generic version |
Pharmacists in tourist areas often understand the word “fexofenadine” or “Allegra” if you need assistance.
Special Considerations for Allegra-D and Combination Products
Important warning: While regular Allegra is permitted, Allegra-D is strictly prohibited in Japan. This is because Allegra-D contains pseudoephedrine, which is classified as a stimulant and is banned under Japanese law.
Other combination products containing fexofenadine may also be problematic if they include:
- Pseudoephedrine
- Codeine
- Certain stimulants or controlled substances
Always check the full ingredient list of any Allegra product you plan to bring. The consequences for unknowingly importing prohibited medications can include confiscation, delays, questioning, and in severe cases, legal penalties.
Quantity Limitations: How Much Allegra Can You Bring?
When traveling to Japan with Allegra, understanding the specific quantity limitations is crucial to avoid issues at customs. Japan has clear guidelines on medication quantities that travelers can bring into the country.
Two-month Supply Limit for OTC Allegra
For over-the-counter (OTC) Allegra, Japan allows travelers to bring up to a two-month supply for personal use. This typically translates to:
- Approximately 60 tablets of standard Allegra (one daily dose)
- Around 120 tablets for twice-daily formulations
Japanese customs officers may use their discretion when determining what constitutes a “reasonable amount” for personal use, but staying within the two-month guideline is generally safe.
One-month Supply Limit for Prescription Allegra
If you’re bringing prescription Allegra (which is less common since Allegra is available OTC in most countries), the rules are more restrictive:
- Only a one-month supply is permitted
- The medication must be accompanied by a valid prescription
- A doctor’s note explaining the medical necessity is highly recommended
Important: Allegra-D or any formulation containing pseudoephedrine is strictly prohibited regardless of quantity, as this ingredient is banned in Japan.
How Japanese Customs Calculates a ‘Month Supply’
Japanese customs officials determine what constitutes a “month supply” based on:
- Standard dosage instructions on the packaging
- Your prescription details (if applicable)
- Length of your stay in Japan
For example, if your Allegra packaging indicates taking one tablet daily, 30 tablets would be considered a one-month supply, and 60 tablets a two-month supply.
Documentation Needed for Larger Quantities
If you need to bring more than the standard allowance of Allegra to Japan, you’ll need to prepare additional documentation:
| Quantity | Required Documentation |
|---|---|
| Within limits (≤2 months OTC, ≤1 month Rx) | Original packaging with visible labels |
| Exceeding limits | Yunyu Kakunin-sho (Import Certificate) |
| Any amount of prescription Allegra | Valid prescription and doctor’s note |
Process for Obtaining Yunyu Kakunin-sho for Longer Stays
For travelers planning extended stays in Japan who need more than the permitted quantity of Allegra, applying for a Yunyu Kakunin-sho (Import Certificate) is necessary:
- Submit an application to Japan’s Ministry of Health, Labour and Welfare at least two weeks before your trip
- Include documentation such as:
- “Yakkan Shoumei” application form
- Copy of your prescription or medical certificate
- Document showing the ingredients and quantity of medication
- Your flight itinerary
- A copy of your passport
The process is free but requires advance planning. Once approved, the certificate will be emailed to you, and you must print and carry it with your medication when entering Japan.
Pro tip: Even with a Yunyu Kakunin-sho, it’s advisable to bring only the amount of medication you’ll reasonably need during your stay, as excessive quantities may still raise questions at customs.
Prohibited Ingredients to Watch For
When planning to bring Allegra to Japan, it’s crucial to understand that not all versions of this popular antihistamine are permitted.
Japan maintains strict regulations on certain pharmaceutical ingredients, and bringing medications containing these substances can lead to serious consequences.
Pseudoephedrine in Allegra-D is Prohibited
Allegra-D is strictly prohibited in Japan due to its pseudoephedrine content. While regular Allegra (fexofenadine) is generally acceptable, the “D” formulation contains pseudoephedrine, a decongestant that is classified as a controlled substance in Japan.
This is because pseudoephedrine can be used in the production of methamphetamine, making it subject to stringent import restrictions.
Important Warning: Attempting to bring Allegra-D into Japan may result in confiscation of the medication and potential legal consequences, including detention or deportation.
If you regularly use Allegra-D, you’ll need to:
- Consult with your doctor before traveling to discuss alternative medications
- Consider switching to regular Allegra (fexofenadine without pseudoephedrine) during your stay
- Research Japan-approved alternatives for managing nasal congestion
Other Common Antihistamine Ingredients to Avoid
Beyond pseudoephedrine, several other ingredients found in allergy medications are restricted or regulated in Japan:
| Prohibited/Restricted Ingredient | Common Medications | Status in Japan |
|---|---|---|
| Pseudoephedrine | Allegra-D, Claritin-D, Zyrtec-D | Prohibited |
| Codeine | Some prescription cough medicines | Strictly controlled |
| Diphenhydramine (in certain quantities) | Benadryl | Restricted above certain amounts |
| Dextromethorphan (in high doses) | Some cough suppressants | Monitored |
| Levocetirizine | Xyzal | Requires documentation if prescription strength |
How to Check Your Medication’s Ingredients
Before packing any medication for Japan, follow these steps:
- Check the active ingredients list on your medication packaging
- Look for the generic name (fexofenadine for regular Allegra)
- Verify combination ingredients (particularly important for “D” formulations)
- Keep medications in their original packaging with clear ingredient labels
- Take photos of ingredient labels as backup documentation
Consequences of Bringing Prohibited Substances
Bringing prohibited medications into Japan can result in several negative outcomes:
- Immediate confiscation of the medication at customs
- Detention for questioning by customs officials
- Significant travel delays while your case is investigated
- Denial of entry into Japan in severe cases
- Legal penalties including fines or potential criminal charges
- Being flagged for additional screening on future visits
Alternative Allergy Medications That Are Safer to Bring
If you’re concerned about bringing Allegra, consider these Japan-friendly alternatives:
- Regular Allegra (fexofenadine without pseudoephedrine) – Generally permitted within quantity limits
- Claritin/Loratadine – Widely available and accepted in Japan
- Zyrtec/Cetirizine – Generally permitted for personal use
- Locally purchased options – Consider buying medication after arrival in Japan
Pro Tip: If you have severe allergies, consider getting a prescription and doctor’s note for your antihistamine medication, even if it’s available over-the-counter in your home country. This provides additional documentation to support your need for the medication.
Remember that regulations can change, so it’s always best to verify the current status of any medication before your trip to Japan.
Required Documentation for Bringing Allegra to Japan
When traveling to Japan with Allegra or any medication, proper documentation is crucial to ensure a smooth experience at customs.
The documentation requirements differ depending on whether you’re bringing over-the-counter (OTC) Allegra or prescription Allegra.
Documentation for OTC Allegra
For over-the-counter Allegra (regular fexofenadine without additional active ingredients), the documentation requirements are relatively straightforward:
- Keep the medication in its original packaging with visible labels
- Ensure the product name and ingredients are clearly visible
- Carry the original receipt if possible (not mandatory but helpful)
- A simple note in English explaining that it’s for personal use during your stay
While OTC Allegra typically doesn’t require extensive documentation, having these items readily available can prevent unnecessary delays at customs.
Documentation for Prescription Allegra
If you’re bringing prescription-strength Allegra to Japan, you’ll need more comprehensive documentation:
- Valid prescription from your doctor (dated within the past year)
- Doctor’s letter or medical certificate explaining:
- Your medical condition
- Why you need the medication
- Dosage information
- Duration of treatment
- Copy of your medical records related to the condition (recommended but not always required)
Important: Prescription medications without proper documentation may be confiscated at customs, potentially leaving you without necessary treatment during your trip.
Doctor’s Note Requirements and Format
Your doctor’s note or medical certificate should follow these guidelines:
- Printed on official letterhead with your doctor’s contact information
- Include your full legal name matching your passport
- Specify the generic name (fexofenadine) and brand name (Allegra)
- Detail the exact dosage and frequency of use
- Be signed and dated by your healthcare provider
- Include your doctor’s medical license number if possible
A well-formatted doctor’s note serves as official verification of your medical need and can significantly smooth your entry process.
Translation Considerations for Medical Documents
While not strictly required, having Japanese translations of your medical documents can be extremely helpful:
- Professional translation is recommended for prescription documentation
- At minimum, have a Japanese translation of the medication name, active ingredients, and your medical condition
- Consider creating a bilingual medication card listing:
- Medication names (both brand and generic)
- Your medical condition
- Emergency contact information
Many Japanese customs officials speak limited English, so translated documents can prevent miscommunication and delays.
How to Prepare Your Documentation Before Travel
Follow these steps to ensure your documentation is properly prepared before your trip:
- Schedule a doctor’s appointment at least 4-6 weeks before your trip
- Request all necessary documentation during your appointment
- Make multiple copies of all documents (keep digital copies too)
- Organize documents in a waterproof folder or envelope
- Pack documentation in your carry-on luggage, not checked baggage
- Create a medication travel kit that includes:
- Original medication in labeled containers
- All documentation
- Emergency contact information
| Documentation Checklist | OTC Allegra | Prescription Allegra |
|---|---|---|
| Original packaging | ✓ | ✓ |
| Receipt | Recommended | Recommended |
| Prescription | ✗ | ✓ |
| Doctor’s letter | ✗ | ✓ |
| Japanese translation | Helpful | Strongly recommended |
Being thorough with your documentation preparation will help ensure that your necessary medications remain with you throughout your Japanese journey, allowing you to manage your allergies effectively while enjoying your trip.
The Yunyu Kakunin-sho Process Explained
When traveling to Japan with certain medications or quantities exceeding standard allowances, you may need to obtain a Yunyu Kakunin-sho (薬監証明) – Japan’s official medication import certificate.
For Allegra users, understanding this process can be crucial if you need to bring more than the standard permitted amounts.
What is a Yunyu Kakunin-sho?
A Yunyu Kakunin-sho is an official document issued by Japan’s Ministry of Health, Labour and Welfare that grants permission to import medications that would otherwise be restricted or limited.
This certificate essentially provides pre-approval for your medication before you arrive in Japan, helping you avoid potential issues at customs.
The certificate serves as proof that:
- Your medication is permitted for import into Japan

Practical Tips for Bringing Medication to Japan
When traveling to Japan with medications like Allegra, proper preparation can save you from headaches at customs. Follow these practical guidelines to ensure a smooth entry with your allergy medication:
Keep Medications in Original Packaging
Always maintain your Allegra and other medications in their original containers with labels intact. This is crucial for several reasons:
- Customs officials can easily identify the medication and its ingredients
- Original packaging shows the medication name, dosage, and manufacturer
- Having prescription information visible (if applicable) validates legitimate medical use
- Loose pills or medications in unmarked containers may raise suspicion and lead to confiscation
“Medications removed from their original containers and placed in unmarked pillboxes or plastic bags are more likely to be questioned or confiscated by Japanese customs officials.”
Properly Declaring Medications at Customs
When entering Japan, you may need to declare your medications:
- Complete the “Declaration of Personal Medications” section on your customs form if provided
- Be proactive and inform customs officers about your Allegra if asked about medications
- Have your documentation easily accessible (prescription, doctor’s note, etc.)
- Remain calm and cooperative if officials need to inspect your medication
Storage Recommendations During Travel
Protecting your medication during travel is essential:
- Store Allegra in your carry-on luggage rather than checked baggage to avoid loss
- Keep medications away from extreme temperatures (avoid direct sunlight or cold cargo holds)
- Consider using pill organizers for daily doses, but always bring the original packaging
- Use waterproof containers or bags to protect medications from humidity or accidental spills
Backup Options if Medication is Confiscated
Despite careful preparation, confiscation can still occur. Have contingency plans:
- Take a photo of your prescription and medication details before travel
- Carry contact information for your doctor who can verify your medication needs
- Research Japanese pharmacies near your accommodation before your trip
- Know the generic name (fexofenadine) to help pharmacists identify alternatives
- Consider bringing less than the maximum allowed amount and having someone ship the remainder if you’re staying long-term
Finding Equivalent Medications in Japan
If you need to purchase Allegra or an equivalent in Japan:
| Japanese Brand Name | Active Ingredient | Equivalent To | Where to Purchase |
|---|---|---|---|
| アレグラ (Allegra) | Fexofenadine | Allegra | Pharmacies, drugstores |
| アレジオン (Allegion) | Epinastine | Similar antihistamine | Pharmacies, drugstores |
| クラリチン (Claritin) | Loratadine | Different antihistamine | Pharmacies |
Most major Japanese cities have pharmacies where staff may speak some English. In Tokyo, Osaka, and other tourist areas, look for drugstore chains like Matsumoto Kiyoshi (マツモトキヨシ) or Sundrug (サンドラッグ) where Allegra is commonly available over-the-counter.
When purchasing medication in Japan, use translation apps or picture cards to communicate your needs if language barriers exist.
Many Japanese pharmacists are familiar with common international medications like Allegra and can help you find suitable alternatives if necessary.
What to Do If You’re Unsure About Your Medication
Even after researching Japan’s medication import regulations, you might still have questions about bringing Allegra or other medications into the country. This uncertainty is completely normal, and there are several reliable resources you can turn to for clarification.
Official Resources to Consult

Remember: Preparation is your best strategy. Researching and preparing proper documentation before your trip will minimize the chances of any issues at customs.
FAQs About Bringing Allegra to Japan
Can I bring Allegra-D to Japan?
No, you cannot bring Allegra-D to Japan. Allegra-D contains pseudoephedrine, which is strictly prohibited in Japan. Japanese customs officials will confiscate any medication containing this ingredient, and you could potentially face legal consequences. Stick to regular Allegra (fexofenadine only) without decongestant components.
Can you mail Allegra to Japan?
Mailing medications to Japan is not recommended. All international packages are subject to the same customs regulations as carried items, and medications sent through mail may be more likely to be inspected, delayed, or confiscated.
If the medication doesn’t comply with Japanese regulations, it will not be delivered to the recipient and could result in complications. If you’re staying in Japan long-term, it’s better to obtain a Yunyu Kakunin-sho or find local alternatives.
What happens if customs confiscates your medication?
If Japanese customs officials confiscate your medication:
- You will not be able to retrieve it
- No compensation will be provided
- You’ll need to find an alternative medication in Japan
- In severe cases involving prohibited substances, you could face questioning or legal consequences
To avoid confiscation, always research regulations before traveling and carry proper documentation.
How strict are Japanese customs officials about medication?
Japanese customs officials are known for being thorough and strict regarding medication imports. While they may not inspect every traveler’s luggage, they conduct random checks and use screening equipment that can detect medications. Officials are particularly vigilant about:
- Medications containing prohibited ingredients
- Quantities exceeding allowed limits
- Medications not in their original packaging
- Unlabeled pills or powders
Their strictness stems from Japan’s stringent pharmaceutical regulations designed to protect public health and safety.
Where to buy Allegra in Japan if needed?
If you need to purchase Allegra in Japan, you have several options:
| Location | Details | Notes |
