Pelack T tablets a and T Cool granules are swallowed medicines for throat inflammation. Pelack Sweet is a different cough-and-phlegm medicine that dissolves in the mouth. A candy-like shape does not make Sweet a flavoured version of T, and the shared brand name is not a reason to take them together.
I'm Irene, a Taiwan-born, Japan-licensed pharmacist working in a Japanese drugstore. With Pelack, I would first check whether the box says T or Sweet (スイート), then check the other medicines already in your bag.

Find these three exact packages
T tablets and granules: similar amounts, different handling
For ages 15 and over, the full daily amount is six T tablets a or three Cool sachets. Each supplies tranexamic acid 750 mg, licorice extract 198 mg (equivalent to 990 mg crude herb), pyridoxine hydrochloride (vitamin B6) 50 mg, riboflavin (vitamin B2) 12 mg and sodium L-ascorbate 500 mg. The tablet label calls its licorice ingredient a crude extract; the granules use a dried extract. Neither contains a sedating antihistamine.
Choose between these two by the form you can take correctly, after checking suitability. Cool describes the sensation, not a higher dose. Granules still need water or warm water. Their aspartame contains an L-phenylalanine compound, so people with phenylketonuria must not use them.
Per 12 drops (the maximum daily amount for ages 15+), Sweet Pineapple S contains dl-methylephedrine hydrochloride 37.5 mg, potassium guaiacolsulfonate 135 mg and cetylpyridinium chloride hydrate (CPC) 6 mg, for cough, phlegm and throat symptoms. It has no tranexamic acid. Blueberry S has the same active ingredients, amounts and directions; flavour and additives differ. Choose a flavour only after choosing the right medicine type.
Adult directions: swallowing versus dissolving
All doses below are for ages 15 and over. The first quantity is one dose; frequency and spacing are separate. Do not use this table to calculate a child's dose.
| Product | One dose, age 15+ | Frequency | How to take it |
|---|---|---|---|
| T tablets a | 2 tablets | 3 times daily: morning, midday and evening | Swallow with water or warm water; before or after food is acceptable |
| T Cool granules | 1 sachet (1.3 g) | 3 times daily: morning, midday and evening | Swallow with water or warm water; before or after food is acceptable |
| Sweet Pineapple S / Blueberry S | 2 drops | 5–6 times daily; at least 2 hours apart | Dissolve slowly in the mouth without chewing |
For T tablets, push the tablets out of the blister before swallowing. Keep the foil pouch opening date on the box: use within six months after opening the pouch and within the printed expiry. If a Cool sachet is divided for a child’s labelled dose, fold the opening closed and use the remainder within two days. A Sweet stick pack contains four drops, not one adult dose; the adult dose is two. Use an opened stick pack promptly and keep all medicines away from children.
T tablets a and Cool granules are not for children under 7. For ages 7–14, the labelled single dose is one tablet or half a sachet, three times daily. Sweet is not for under-5s; ages 5–7 take one drop per dose, while ages 8 and over take two, 5–6 times daily with at least two hours between doses. Children need adult supervision.
The safety check that matters most
For either T product: do not take another oral medicine containing tranexamic acid, licorice (甘草／カンゾウ) or glycyrrhizin at the same time. These ingredients can also appear in cold, rhinitis, pain, cough or other throat medicines. Do not use T tablets and T granules together or use them continuously for a long period.
Ask before taking T if you are receiving medical/dental treatment, may be pregnant, are older, have a drug-allergy history, swelling, hypertension, heart/kidney disease, a blood clot or a risk of thrombosis. Stop and obtain prompt medical care for progressively worsening limb weakness, stiffness or muscle pain, which the label identifies as possible serious adverse effects.
For Sweet: do not combine with other cough/expectorant medicines, cold medicines or sedatives. Ask before use with treatment, pregnancy, breastfeeding, older age, drug-allergy history, high fever, heart disease, hypertension, diabetes or thyroid disease. “Sugar-free” does not override these cautions.
The stop-and-consult timing differs: T tablets/Cool granules: no improvement after 5–6 days; Sweet: no improvement after 5–6 doses. Stop earlier for suspected side effects such as rash, nausea or dizziness. Do not wait for the stated interval if symptoms are worsening or severe.
A current shelf note
As checked on October 13, 2026, the manufacturer temporarily suspends sales of the 20-sachet Cool granules pack and Sweet Lime S for production reasons, stating that this is not a quality issue. The 10-sachet granules pack, T tablets a, Sweet Pineapple S and Blueberry S remain listed without those notices. Listings do not guarantee a particular shop's stock.
The short version: T tablets a versus Cool is mainly a swallowed-form choice; Sweet is a separate cough/phlegm branch. Match the symptoms and duplication warnings first, then the form and flavour.
