Buying Yeast Infection Medicine on Amazon Japan

You search Amazon Japan for yeast infection medicine, add Meditreat to your cart, and a form in Japanese appears before you can pay: about ten questions about the person who will use the medicine. It looks like a lot. It isn't, once you know what each question means.

Meditreat is a Class 1 medicine (第1類医薬品). In Japan, a pharmacist has to check before a Class 1 medicine is sold, and that rule applies online too. Here is the form in English, the answers that stop an order, and what happens after you press submit.

This is the screen: Amazon Japan, October 2026, with example answers (age 28, 女性 female). The form can change over time.

Is This Medicine for You? First Time vs. It Came Back

Meditreat is made for one situation: a vaginal yeast infection (candidiasis) that has come back after a doctor already diagnosed and treated it. The package insert says so directly, and it is for women aged 15 to 59.

If this is your first time with these symptoms, don't order it. Other conditions can cause the same symptoms, and a doctor needs to find out which one you have. In Japan, see a gynecologist (婦人科 or 産婦人科) first. A women's clinic (レディースクリニック) works too. (Source: Sato Pharmaceutical)

Who Cannot Buy Meditreat: Four Answers That Stop an Order

The form lists four situations where you should not buy. The reasons come from the Japanese package insert, where it gives one.

The form shows only four. The package insert lists more: don't use it if you are under 15 or 60 or older, pregnant or possibly pregnant, or have fever, chills, lower abdominal pain, colored or fishy-smelling discharge, abnormal bleeding, or sores. OTC Guide Japan has translated the full list on the Meditreat Vaginal Suppositories page.

The Amazon Japan Form, Question by Question

This is the form from the screenshot at the top of this page (Meditreat, 6 suppositories). The top of the page says to answer about the person who will use the medicine (必ずお薬のご使用者様本人の情報をご記載ください).

The form changes with your answers. When we chose 女性 (Female) for question 3, two more questions appeared: pregnancy (3-1) and breastfeeding (3-2). Nothing else was added, and these two questions don't appear when 男性 (Male) is chosen. (The screenshot above is the female version.) They are shaded in the table below. Pregnancy matters because the package insert says not to use Meditreat if you are pregnant or may be pregnant, and to talk to a doctor or pharmacist first if you are breastfeeding.

What Happens After You Submit

After you press 提出 (Submit), Amazon shows a second screen: STEP 2/2, お薬の説明と確認 (medicine explanation and confirmation). This is not the payment screen. Payment comes after it.

STEP 2/2 for Meditreat, Amazon Japan, October 2026.

This screen repeats the key points of the package insert:

• Talk to a doctor or pharmacist first if you are under hospital care, you are breastfeeding, or a medicine once gave you a rash.
• How to use it: one suppository at bedtime for 6 days, in the vagina only. Not for under 15 or 60 and over, and not during your period. Keep it away from latex condoms and diaphragms.
• When to see a doctor: no improvement after 3 days, or symptoms still there after 6 days.

The Pharmacist Check: What the Notes on That Screen Say

At the bottom of STEP 2/2, Amazon lists these notes about the order (our translation):

• The medicine ships only after an expert has confirmed proper use (for some products, by video call). The delivery date shown on the order confirmation screen may change.
• If the expert decides it is not proper use, the order is cancelled.
• Sold and shipped by Amazon: depending on your answers, an expert may contact you directly. If you get an email titled 「医薬品に関する適正使用確認のお知らせ」 (notice of proper-use confirmation), follow the instructions in it to get the explanation.
• Sold and shipped by a seller (出品者): depending on your answers, the seller's expert may contact you. The expert will call your phone number, so check that the phone number saved with your delivery address is correct.
• In both cases, if the check isn't finished within a set period, all the medicines in the order are cancelled.
• Medical history needs the person's own consent. If you are buying for someone else, don't put information in the form that shows your relationship to them or identifies them.

Who sells it matters. When we checked in October 2026, the Meditreat listing was sold and shipped by a seller (エナジードラッグ), not by Amazon itself. The "Sold by" line on the product page tells you which case you are in. (Amazon's own guide describes the same order.)

What the expert asks isn't written on the screen, so we can't tell you. The screen is in Japanese, so expect Japanese. Keep your phone nearby after you order, and pick up numbers you don't know. A Japanese-speaking friend or a translation app helps.

Suppository, Cream, or Both?

Taisho, the maker, has a pre-purchase check sheet that helps you choose by where your symptoms are:

• Only inside the vagina: Meditreat Vaginal Suppositories.
• Inside the vagina and on the outer area (vulva): the suppositories together with Meditreat Cream.
• Only on the outer area: Meditreat Cream. The sheet adds that using the suppositories as well is desirable, because the cause may also be inside the vagina.

Other Class 1 yeast infection medicines on this site: Empecid L, Flady CC, Flady CC1, and Okinazole L100. Each product can show its own questions, so the form you see may not match the one above.
