Question
You're visiting London, catch a sore throat, and grab Strepsils (アメジスト含有トローチ / throat lozenge) from Boots. Back home in Japan, you want the same thing. Which Japanese OTC is your closest match?
A) ノーズシャット（Nose Shut）
B) 龍角散（Ryūkakusan powder）
C) ペラックT（Perac T）
D) ストレプシル / ストレプスキン（Strepsil / Strepskin—Japanese import)
Hints
- Strepsils contains: hexylresorcinol (an antiseptic lozenge, 2.4 mg per tablet), plus amylmetacresol in some formulations
- Not a systemic antibiotic—acts locally on throat tissues only
- Common in UK, Ireland, Australia, New Zealand—rare in Japan
- Japanese pharmacies stock far fewer imported lozenges than UK/AU counterparts
- Active ingredients matter more than brand names when traveling: look for "throat antiseptic" (喉の殺菌 / nodo no sakkin) or "local anesthetic" (局所麻酔 / kyokusho masui)
Answer
Correct: D (Strepsil / Strepskin—Japanese import) — BUT with caveats
Why This Is Tricky
Strepsils is technically sold in Japan—but not in most neighborhood drugstores. You'll find it only in:
- Large international pharmacy chains (e.g., Watsons in major cities)
- Airport pharmacies (Narita, Haneda, Kansai)
- Online retailers (Amazon Japan, Rakuten)
If you can't find it, these Japanese OTC lozenges are closer alternatives:
| Product | Active Ingredient | How It Works | Closest to Strepsils? |
|---|---|---|---|
| ペラックT (Perac T) | Cetylpyridinium chloride (CPC) + local anesthetic | Antiseptic throat lozenge | ✅ Yes—similar mechanism |
| 龍角散 (Ryūkakusan) | Herbal powder (licorice, mint, ginger) | Soothing, anti-inflammatory | ⚠ Different (natural blend) |
| トローチ系 (Generic throat lozenges) | Varies (CPC, benzocaine, iodine) | Local antiseptic/anesthetic | ✅ Often comparable |
| ノーズシャット (Nose Shut) | Mint oil, camphor, eucalyptus | Nasal comfort—NOT for throat | ❌ Wrong product entirely |
Why Strepsils Isn't Everywhere in Japan
Regulatory & Market Reasons
- Japan has its own throat lozenge market dominated by domestic brands (Perac, Azulen-based products, herbal options)
- Hexylresorcinol (Strepsils' main ingredient) isn't as common in Japanese OTC formulations—Japanese pharmacists prefer CPC (Cetylpyridinium chloride) or traditional herbal antiseptics
- Import tariffs + distribution costs make UK lozenges 2–3× more expensive than domestic equivalents
- Minor regulatory differences: Japan's Pharmaceutical Affairs Bureau (PMDA) reviews imported drugs individually; Strepsils must be re-registered per product variant
What to Ask for at a Japanese Pharmacy
If you want something as close as possible to Strepsils:
English:
Do you have throat lozenges with an antiseptic ingredient?
（ドゥ ユー ハヴ スロート ローゼンジズ ウィズ エン アンティセプティック インガリディエント？）
Japanese:
「喉の殺菌成分が入ったトローチはありますか？」
（「のどの さっきん せいぶん が はいった とろーち は ありますか？」）
Better option:
I'd like a throat lozenge similar to UK Strepsils.
（アイド ライク ア スロート ローゼンジ シミラー トゥ ユーケー ストレプシルズ。）
Pharmacists in urban areas will often understand and direct you to ペラックT or ストレプシル (if in stock).
Pharmacist's Note
When you can't find your go-to brand abroad, prioritize the active ingredient, not the brand name. Strepsils works because hexylresorcinol kills throat bacteria locally—but so does CPC (in ペラックT) or benzocaine (a mild numbing agent). The mechanism matters; the label doesn't. Always ask a pharmacist—in any country—to compare active ingredients, not just brand recognition. This principle applies to pain relievers, antihistamines, and digestive aids too. Your body doesn't know the brand; it only knows the chemistry.
Pro Tip: Pack Strepsils for Asia Travel
If Strepsils is your trusted throat lozenge, bring a few blister packs in your carry-on when traveling to Asia. You can legally import a personal supply (typically <1 month's worth) for your own use. This avoids language barriers and pharmacy hunting, especially if you develop a sore throat on day 1 of a trip.
Quick Reference: Throat Lozenge Equivalents
| Country | Popular Brand | Active Ingredient |
|---|---|---|
| UK / Ireland / AU | Strepsils, Lockets | Hexylresorcinol / CPC |
| Japan | ペラックT, ストレプシル | CPC / Hexylresorcinol |
| USA | Cepacol, Ricola | CPC / Herbal blend |
| France | Strepsils (imported), Tantum Verde | Benzydamine |
| India | Strepsils (available), Halls | Menthol / CPC |
Bottom Line
Strepsils → Japan: Import it yourself, or buy ペラックT (Perac T) as the nearest OTC equivalent. Both are safe, local-acting antiseptic lozenges—but Perac T is cheaper, easier to find, and just as effective for a scratchy throat. No prescription needed anywhere on this list.
