If you have a fever, cough or sore throat, you need treatment, not prevention. Please see a nearby clinic.
Had your flu shot?
Add one more layer.
The flu vaccine is the foundation of prevention. But the vaccine strains don't always match the flu that spreads that year, so you can still catch it. Preventive flu medication stops the virus from multiplying after it enters your body, so the illness doesn't develop.

Protection for the season

- May not match the strain that spreads
- Helps prevent severe illness

Frequently asked questions
Q. I already have a fever. Can I still book?
Preventive medication isn't suitable once you have symptoms. You need treatment, so please see a nearby clinic.
Q. When should I start taking it?
If someone at home has the flu, start within 48 hours of your last contact. If you're planning a trip or have a big event coming up, the doctor will suggest a start date.
Q. My trip is longer than 10 days.
Protection lasts 7 days with oseltamivir and about 10 days with Xofluza, so one course can't cover the whole trip. Tell us your travel dates and the doctor will suggest when to start, around the part of your trip that matters most.
Q. I'm visiting Japan. Where should I have it delivered?
To the hotel where you'll be staying when it arrives. Delivery to some areas takes 2 to 3 days, so if you're heading to the mountains or a ski resort, it's easiest to receive it in Tokyo before you go.
Q. Someone in my family has the flu. What should I do?
Start within 48 hours of your last contact. If you're in a hurry and are in central Tokyo (the 23 wards), you can choose same-day delivery (+¥5,500).
Q. Are there side effects?
Oseltamivir can cause stomach pain, diarrhea or nausea. Xofluza can cause diarrhea or a headache. Rarely, serious reactions such as anaphylaxis can occur, so seek medical care straight away if you have trouble breathing or hives.
Q. Can men book?
Yes. We are a gynecology clinic, but men are welcome for flu prevention medication.
Q. Can children book?
Yes, from age 12 (oseltamivir from 37.5 kg body weight). Patients under 18 must be seen with a parent or guardian.
Q. Can I get medication for my whole family at once?
We can only prescribe to the person who had the consultation, so each person needs their own booking.
Q. Can I take it while pregnant or breastfeeding?
Please tell the doctor at the consultation. The doctor will decide based on your situation.
Q. Is it covered by insurance?
No. Preventive flu medication is self-paid in Japan.
Q. Can I claim it on my travel insurance?
We can issue a receipt in Japanese. If your insurer needs an English medical certificate, we can issue one for ¥3,300. Please ask at the consultation.
Q. Can you send it to me outside Japan?
No. We can only deliver to addresses in Japan, such as your home or hotel.
Q. How soon will it arrive?
As early as the next day, anywhere in Japan. Some areas take 2 to 3 days. In central Tokyo (the 23 wards), same-day delivery is available (+¥5,500).
