I’m Irene, a Taiwanese pharmacist working in a Japanese drugstore. A green Solmack bottle can catch your eye after a busy day of eating on a trip, but the full name matters. Solmack 胃腸液プラスR launched in Japan on November 6, 2026. It has its own formula and dosing schedule, and it is not a protective drink that makes heavier drinking safe.
Find the R at the end of the name
The full Japanese name is ソルマック胃腸液プラスR. It is a designated quasi-drug in Japan, not an ordinary beverage or a second-class OTC stomach medicine. The single-bottle JAN code is 45209680. The official launch date does not guarantee stock in a particular shop.
Taiho describes R as the successor to the discontinued ソルマック胃腸液プラス, retaining a similar formula and taste. Similar does not mean identical: do not use an old ingredient list, alcohol figure or photograph to identify the new R bottle. Solmack 5 and Solmack Q-Arl D are different products too.
What is it intended to relieve?
R is indicated for stomach discomfort and nausea caused by overeating or overdrinking, including queasiness associated with a hangover or drinking too much. That does not establish that it treats every hangover symptom, speeds up sobriety, lowers blood alcohol or prevents liver damage. Do not use it as a reason to drink more, or assume that feeling better means it is safe to drive.
If your main problem is diarrhea, persistent stomach pain, repeated vomiting or symptoms with no clear cause, seek medical advice rather than choosing another bottle by brand name alone.
One bottle, once a day: the use sequence
Take it once daily, before or between meals. “Between meals” means the interval between meals, not while eating. R is not labeled for an after-meal dose. More meals or another drinking occasion do not justify another bottle that day.
Herbal ingredients can settle, so shake well as directed. Do not keep leftover liquid after opening or transfer it to another container.
This original sequence explains the current R label. Read it together with the consultation, stopping and storage advice below.
Seven active ingredients: read the units carefully
Each 50 mL bottle contains turmeric extract 30 mg (equivalent to 300 mg turmeric), Isodonis herb extract 15.46 mg (equivalent to 201 mg herb), ginseng extract 90.4 mg (equivalent to 606 mg ginseng), cinnamon oil 1.5 mg, clove oil 5 mg, carnitine chloride 120 mg and dipotassium glycyrrhizinate 7.2 mg.
The amounts in brackets are crude-herb equivalents, not extra amounts to add to the extract figures. Comparing extract milligrams alone also does not establish that one version works better.
Inactive ingredients include fructose, glucose, menthol and ethanol. Current R information lists no more than 0.005 mL of alcohol per bottle; that is not an alcohol-free claim. If you need to avoid alcohol, sugars or a particular ingredient, show the complete current label to a pharmacist.
When should you ask or stop?
If symptoms do not improve after taking it for a while: stop and consult one of those professionals, taking the product with you. The R label does not specify a fixed multi-day course. Do not borrow a stopping interval from another product.
General safety advice: Seek medical advice for abdominal pain that persists or keeps returning. Sudden severe abdominal pain, vomiting blood or black, sticky stools need urgent assessment. Reduced consciousness or slow/irregular breathing after drinking can indicate alcohol poisoning: seek emergency medical help immediately. Do not wait for this product to work.
Storing it during a trip
Keep unopened bottles in a cool place away from direct sunlight and out of children’s reach. Do not take the product after its expiry date, save an opened bottle for the next day or remove the label you may need for checking instructions.
