“Vicks” on the front does not tell you whether you are buying a cough medicine, a medicated throat drop or ordinary candy. Even two boxes of Medicated Drops can have different dose instructions. Read the full product name before choosing a flavour.
Hi, I’m Irene, a Taiwan-born pharmacist licensed in Japan and working in a Japanese drugstore. I’ll help you separate these Japanese packages and the small but important instructions on the back. Here’s more about me.
Checked October 15, 2026. This comparison covers Medical Troche L, regular Lemon Medicated Drops, Sugarless Acerola Medicated Drops, and Sukkiri Amakunai throat candy in individual wrappers. Other flavours and other Medical Troche versions need their own labels; this is not an all-series dose guide.
Before reaching for a lozenge
Difficulty breathing, inability to swallow, drooling, noisy high-pitched breathing or severe symptoms that worsen quickly need emergency medical care. High fever, dehydration or a weakened immune system also call for prompt assessment. Do not keep trying different throat products while waiting for these symptoms to settle.
For uncomplicated discomfort, drinking water, resting and avoiding smoke can help. Small hard sweets are a choking risk for young children. A medicine’s minimum age is only one condition; a child also needs to be able to use a lozenge safely under supervision.
The four packages at a glance
| Exact product in this guide | Japanese classification | Main labeled purpose |
|---|---|---|
| ヴイックス メディカル トローチL | 第2類医薬品, Class 2 OTC medicine | Cough, phlegm and throat-inflammation symptoms |
| メディケイテッド ドロップ レモン; sales name ドロップL | 指定医薬部外品, designated quasi-drug | Throat-inflammation symptoms, oral disinfection and bad breath |
| メディケイテッド ドロップ シュガーレス アセロラ; sales name ドロップAC | 指定医薬部外品, designated quasi-drug | The same listed purposes as the Lemon drops |
| すっきり甘くないのど飴（個包装） | 食品, food | Ordinary throat candy; no medicine treatment indication |
Medical Troche L and Medicated Drops L are different products. The letter L alone is not enough to identify what you have.
Medical Troche L: cough medicine in a lozenge
This honey-lemon-flavoured product contains three active ingredients per tablet: cetylpyridinium chloride hydrate (CPC) 1 mg, dextromethorphan phenolphthalinate 7.5 mg and potassium guaiacolsulfonate 22.5 mg. The ingredients provide antiseptic, cough-suppressing and expectorant actions. Its indications include cough, phlegm, and hoarseness, irritation, discomfort, pain or swelling caused by throat inflammation.
For ages eight and older, the labeled dose is one tablet, six times daily, with at least two hours between doses. Under-eight children must not take it. Remove the tablet completely from its blister, then let it dissolve slowly in the mouth without chewing or swallowing it whole. Supervise children.
Important restrictions
- Do not take it if you have had an allergic reaction to the product or an ingredient.
- While taking it, do not use other cough/expectorant medicines, cold medicines or sedatives.
- Do not drive or operate machinery after taking it: drowsiness can occur.
- Ask first if receiving medical treatment, pregnant or possibly pregnant, have a medicine-allergy history, or have a high fever. Show the pharmacist all other medicines you take.
The exact L leaflet does not give a separate breastfeeding restriction; ask for individual advice rather than treating that omission as a guarantee.
Stop and consult for rash, redness, itching, nausea, vomiting, loss of appetite, dizziness or breathlessness. Persistent or worsening drowsiness also means stop and consult. Signs of a severe allergy, such as hives with hoarseness, breathing difficulty, palpitations or confusion, need immediate medical attention.
If there is no improvement after five to six doses, stop and consult. This says doses, not days. Do not extend the trial because the medicine tastes like a sweet.
Lemon versus Sugarless Acerola Drops: the dose changes
These two products contain CPC as their active ingredient, without Medical Troche L’s cough suppressant and expectorant. Both are designated quasi-drugs, with instructions that still need to be followed.
| Product | Age | Pieces in one dose | Doses per day | Interval |
|---|---|---|---|---|
| Regular Lemon | 15+ | 3 | 4–6 | Follow its own package; no numerical interval is stated in this exact label |
| Regular Lemon | 5–14 | 2 | 4–6 | Same exact-label instruction |
| Sugarless Acerola | 5+ | 2 | 3–6 | At least 2 hours |
| Either product | Under 5 | Do not use | — | — |
One dose can contain several pieces, but dissolve only one piece at a time. For example, an adult Lemon dose means three pieces in sequence, not three in the mouth together. Do not chew or swallow them whole. Children need adult supervision.
The labeled ingredient bases also differ: Lemon has CPC 8.28 mg per 18 pieces; Sugarless Acerola has CPC 6.0 mg per 12 pieces. Do not compare those numbers as if they described the same number of pieces, and do not increase the dose to chase a higher CPC amount.
Before and during use
Consult a doctor, dentist or pharmacist first if receiving medical or dental treatment, pregnant or possibly pregnant, personally or through your family prone to allergies, or have had a medicine allergy. Ask individually about breastfeeding or combining other throat products.
If rash, redness or itching appears, stop immediately and consult. If symptoms have not improved after one week, stop and consult. Earlier warning signs still override that one-week review point.
Regular Lemon lists glucose syrup and sugar. Sugarless Acerola has a different sweetener mixture and lists aspartame, an L-phenylalanine compound. Check the exact ingredients if you have dietary or medical restrictions. “Sugarless” does not remove the dose limits or make it ordinary candy.
Sukkiri Amakunai throat candy: food, not cough medicine
The individually wrapped 70 g product is ordinary food. The manufacturer lists starch syrup, sugar, peppermint extract, lime juice and other food ingredients. The name “not sweet” is a comparison with the manufacturer’s previous product; it does not mean sugar-free.
There is no medicine dose to borrow from the drops or troches. Choose this candy for its flavour and feel in the mouth. It is not a treatment for a throat infection or a substitute for medicine or medical care when needed. Check food ingredients and choking suitability rather than assuming the blue Vicks logo means the same formula as the yellow medicine box.
Keeping them in a travel bag
Keep the medicines and quasi-drugs in their original packaging, away from children, direct sunlight, heat and moisture. Do not use after expiry.
- Medical Troche L: use within six months of opening, even if the printed expiry is later. Keep the blister and instructions; never swallow a tablet still inside blister packaging.
- The two Medicated Drops: they absorb moisture, so fold the opened bag mouth closed for storage. Do not transfer this instruction into a six-month rule; their exact labels do not give that rule.
- Ordinary candy: follow its food date label and store away from sunlight, high temperatures and humidity.
Check the complete name, classification and directions on the package you actually buy in Japan. A similar flavour or overseas Vicks name is not enough to transfer these instructions.
