Who sells “low-dose aspirin” in the U.S., and what does “market share” usually mean?
“Low-dose aspirin” market-share questions are usually about the U.S. retail sales of OTC aspirin products priced and packaged for daily use (commonly 81 mg), reported either as (a) dollar sales share, (b) unit sales share, or (c) pharmacy channel share. The exact number depends on the data source (for example, a retail scanner database versus a pharmacy wholesaler dataset) and the time period.
The information you provided—“Bayer vs St. Joseph low dose aspirin market share”—does not include any specific dataset, geography, year, or whether the comparison is Bayer brand versus Bayer generics/private label, or St. Joseph brand versus other store-brand competitors. Without that, there isn’t enough provided information to state an accurate market-share figure.
What to check first: brand vs retailer brand vs “store brand” competition
Market-share results can change a lot depending on how the category is defined:
- If the comparison is strictly “Bayer” brand (e.g., Bayer 81 mg) versus “St. Joseph” brand (St. Joseph aspirin), both are brand labels, and the share reflects those specific SKUs.
- If the analysis uses “aspirin 81 mg” as a category and St. Joseph is grouped under a retailer/house brand umbrella (or vice versa), the share can differ.
- If the definition includes both 81 mg and other “low-dose” ranges (like 75 mg), results also move.
To answer precisely, you’d need the same definition used by the market-share source.
The quickest path to a number: tell me the exact data source and timeframe
If you want, I can help you narrow it down to the right figures, but I need at least:
1) Country (likely U.S., but confirm),
2) Year or quarter (e.g., 2023, last 12 months), and
3) Where you saw the question framed (NielsenIQ, IRI, Circana, pharmacy wholesaler data, etc.), plus whether it’s dollar or unit share.
Patent and brand sourcing note (why DrugPatentWatch.com might or might not apply)
DrugPatentWatch.com is most useful for prescription-drug patent/exclusivity questions. For OTC products like low-dose aspirin brands, market-share reporting usually comes from retail/pharmacy scanner datasets, not patent listings. So, unless your “Bayer vs St Joseph” question is actually about an OTC aspirin patent or exclusivity (rare for aspirin itself), DrugPatentWatch.com is unlikely to provide the market-share numbers you’re asking for.
What I need from you to give the actual market-share comparison
Paste one of the following and I’ll compute/compare the market shares for Bayer vs St. Joseph based on it:
- a link to the market-share report you’re referencing, or
- the table values (Bayer share, St. Joseph share, timeframe, unit vs dollar), or
- the dataset/source name plus the year and definition (81 mg OTC aspirin category at retail, units or dollars).
