Can't Find Your Go-To Medicine in Japan? A Guide for US Travelers

You packed everything you needed for your dream trip to Japan. But then, a sudden bout of heartburn or digestive discomfort sends you to a Japanese drugstore. You scan the shelves for your trusted, go-to brand from the US, but it's nowhere to be found. This experience is surprisingly common for American travelers, and it can be a source of significant stress when you're feeling unwell.

This guide is here to help. We'll explain how get some common over-the-counter (OTC) drugs from the USA in Japan, and what to do if sick in Japan when you can't get the medicine you need. This information, aligned with guidance from Japanese health authorities, will help you navigate the pharmacy aisles with confidence.

Why Are Some Medicines Regulated Differently?

Every country has its own regulatory body—the FDA in the United States and the Ministry of Health, Labour and Welfare (MHLW) in Japan—that decides which medications are safe for sale without a doctor's supervision. These decisions are often based on the active ingredients, their dosage, and their potential for misuse or side effects. This is why a medicine you can easily buy at a CVS or Walgreens might be kept behind the pharmacist's counter or require a prescription in Japan.

Common Medicines: OTC in the US, Prescription-Needed in Japan

Here are some of the most common categories of medications that catch US travelers by surprise. Being aware of these differences can save you time and anxiety.

Proton Pump Inhibitors (PPIs) for Heartburn

In the US, many travelers rely on over-the-counter PPIs like Esomeprazole (Nexium®) for frequent heartburn. In Japan, these specific ingredients are prescription-only. While Japan did recently approve Lansoprazole and Rabeprazole for sale, they are not on regular shelves and you must purchase them at a pharmacy with a registered pharmacist present and receive a direct consultation. These are less accessible than simple antacids like H2 blockers (e.g., Gaster10) or chewable tablets, which are widely available for immediate, mild relief.

Certain Constipation Remedies (Lactulose & Macrogol)

Changes in diet and routine make constipation a common travel ailment. In the US, gentle, less-stimulant osmotic laxatives like Macrogol 3350 (the ingredient in Miralax®) and Lactulose are common OTC solutions. However, in Japan, both of these ingredients are prescription-only. Japanese drugstores offer a wide variety of effective OTC constipation remedies (便秘薬 - benpi-yaku), but they are predominantly stimulant laxatives (containing ingredients like Senna or Bisacodyl), which work differently and can be harsher than what you're used to. If you require a gentler, less-stimulant option, you will need to find some medicines, such as magnesium oxide.

Stronger Allergy Medications & Inhalers

While you can find many good antihistamines in Japan, some second-generation allergy medications or combination products (especially those mixed with a decongestant) might require a prescription. Furthermore, life-saving devices like emergency asthma inhalers (e.g., Albuterol/Salbutamol) are strictly prescription-only and cannot be purchased over the counter under any circumstances.

So, What's Your Action Plan?

You're in a Japanese drugstore, feeling unwell, and can't find what you need. Don't panic. Here's what to do.

Step 1: Talk to the Pharmacist (Yakuzaishi)

Pharmacists in Japan are highly knowledgeable professionals. Even with a language barrier, they can be incredibly helpful.

• Use a translation app on your phone to describe your symptoms (e.g., "heartburn," "constipation").
• Show them a picture of your US medicine box or the active ingredient name.
• They can recommend the best available Japanese OTC alternative for your symptoms. This is often the quickest and easiest solution.

Step 2: When an OTC Alternative Isn't Enough...

Sometimes, an alternative just won't do. You might need that specific ingredient, or your symptoms might be severe enough that a proper medical diagnosis is necessary. This leads to the classic traveler's dilemma: How do I see a doctor? You might start searching for a "medical clinic near me" or a "clinic near me open now," and then worry about finding an English-speaking doctor or trying to explain your needs to a Japanese doctor.

This is precisely the situation where an online doctor service becomes invaluable. Instead of navigating an unfamiliar city while sick, you can get the help you need right from your hotel room.

• Get a Prescription Without Leaving Your Room: After an online doctor consultation, the online doctor can, if medically appropriate, issue a prescription for the medication you need. This is the key to accessing drugs like Omeprazole or a gentle laxative like Macrogol.
• Speak to an English-Speaking Doctor: There is no language barrier. You can have a clear conversation with an English-speaking doctor, explain your medical history, and describe your symptoms accurately. It's a reliable alternative to searching for "English doctor Tokyo" or hoping for luck at a random clinic.
• Fast and Easy: Making an online doctor appointment is quick and bypasses the entire process of finding a clinic, traveling, and waiting. It's a modern, efficient "online clinic" service.
• Get a Medical Certificate: If you need documentation for your travel insurance, you can often receive a medical certificate online, simplifying your paperwork.

Conclusion: Travel with Knowledge and Peace of Mind

Being a sick tourist in Japan is much less stressful when you're prepared. Understanding that medication rules differ is the first step. For many common ailments, a Japanese pharmacist can provide an excellent OTC solution. But for those times when you need a prescription for something you'd normally buy off the shelf back home, it's reassuring to know that a service like HOTEL de DOCTOR 24 exists to bridge the gap quickly and professionally.
