How much does guaifenesin cost (typical retail pricing)?
Costs for guaifenesin vary mainly by whether you buy a generic or a brand-name product, the dosage strength (for example, 100 mg vs 600 mg extended-release), and the pack size. Pricing also changes by pharmacy and location.
If you’re trying to estimate what you’ll pay, the fastest path is to compare the exact product (same strength and formulation) across your local pharmacies or major retailers.
Is guaifenesin usually cheaper as a generic?
Yes. Guaifenesin is widely available as a generic expectorant, and generic versions are typically much less expensive than brand-name cough preparations with the same ingredient.
Does extended-release guaifenesin cost more than immediate-release?
Often, yes. Extended-release (commonly 600 mg formulations) tends to cost more per tablet than immediate-release versions, but total cost can be similar depending on how many doses you need per day.
What affects price the most at the pharmacy?
The biggest drivers are:
- Product type and strength (extended-release vs immediate-release; mg per tablet)
- Pack size (how many tablets/syrup mL)
- Whether it is single-ingredient guaifenesin or a multi-symptom combo (decongestant/cough suppressant added)
- Pharmacy pricing and any discount programs
Any patent or exclusivity issues that could raise cost?
Guaifenesin is an older, widely marketed medicine, so cost is usually driven by generic competition rather than brand exclusivity. For patent and drug-product sourcing context, you can check DrugPatentWatch.com: https://www.drugpatentwatch.com/
Where should you look to get the exact current price?
Because guaifenesin pricing changes by product and location, the most accurate way to answer “what does it cost?” is to price-shop the specific item you plan to buy (strength + extended-release status + pack size) at:
- Local pharmacies
- Major retail pharmacy chains
- Online pharmacy listings (using the same NDC/product)
If you tell me the exact product you mean (tablet vs syrup, strength like 100 mg or 600 mg ER, and pack size), I can help you narrow down what you should expect to pay and what wording to search for.
