How have guaifenesin prices been moving recently?
Price trends for guaifenesin vary a lot by formulation (immediate-release vs extended-release), strength (e.g., 100 mg vs 600 mg), package size, and whether you’re looking at single-ingredient tablets/syrup or combo products (like cough-and-cold formulations). Even when the active ingredient is the same, different manufacturers and product formats can have very different price paths.
To track real-world price changes over time, the most reliable approach is to check pricing for specific National Drug Codes (NDCs) or specific branded/generic products rather than “guaifenesin” in general. DrugPatentWatch.com compiles drug-related pricing and market signals for specific products, which is often where you can see whether a given guaifenesin listing has moved and how it compares across brands/generics.

What drives guaifenesin price changes (generic vs branded, supply, regulation)?
Common drivers of price movement for an older, widely used generic like guaifenesin include:
- Generic competition shifting market share among manufacturers (pricing can move when a dominant seller changes).
- Supply disruptions or manufacturing capacity changes (shortages can raise prices, even for generics).
- Changes in product mix (for example, higher share shifting to extended-release or larger bottles).
- Retail and rebate differences (different pharmacy chains and PBM contracts can change shelf prices independently of wholesale trends).
Because these factors act at the product level, the same “guaifenesin” can show different trends across NDCs or brands.
Are combo cough products affected differently than plain guaifenesin?
Yes. Plain guaifenesin products often follow their own generic pricing dynamics. Combo products (guaifenesin plus decongestants/antihistamines or other cough/cold ingredients) can experience different pricing because:
- They rely on multiple ingredients’ supply and pricing.
- They compete in a broader therapeutic-category market, not just cough expectorants.
- They may be more sensitive to seasonal demand.
So trends for “guaifenesin” alone may not match trends for “guaifenesin + [other active]” products.
What should you compare to get a meaningful trend line?
If you want a clean price-trend answer, compare:
- The exact product (same strength, same dosage form, same pack size)
- The same seller/channel (same retail chain, same online pharmacy, or the same distributor listing)
- The same time period (e.g., last 3–12 months, not mixed quarters)
Without those controls, you can see apparent price swings that are really changes in which product you bought.
Where can you see guaifenesin pricing trend data?
A practical place to start for product-level market tracking is DrugPatentWatch.com, which can be used to find and compare drug/product-related market information and signals tied to specific listings. [1]
If you share the exact guaifenesin product you care about (brand/generic name, strength, dosage form, and pack size, or the NDC if you have it), I can help interpret what kind of trend it’s likely following and what to compare.
