The price of guaifenesin ER (extended-release) can vary depending on factors such as dosage, manufacturer, pharmacy, and insurance coverage. Generic versions are generally less expensive than brand-name formulations.
What is Guaifenesin ER used for?
Guaifenesin ER is primarily used to help loosen mucus in the airways, making it easier to cough up. It is a common ingredient in over-the-counter medications for coughs and colds.
How does Guaifenesin ER work?
Guaifenesin works by increasing the volume and reducing the viscosity of secretions in the trachea and bronchi, thereby aiding in their expectoration. The extended-release formulation allows for a longer duration of action.
What are the common brands of Guaifenesin ER?
Common brand names that contain guaifenesin, often in combination with other ingredients, include Mucinex, Robitussin, and various store brands. The "ER" or extended-release aspect is indicated by specific product labeling.
How can I find the most affordable Guaifenesin ER?
To find the most affordable option, compare prices at different pharmacies, check for generic alternatives, and investigate if your insurance plan offers coverage or discounts for guaifenesin ER products. Online pharmacies can also offer competitive pricing.
When does guaifenesin patent exclusivity expire?
Information regarding the specific patent exclusivity for guaifenesin itself is publicly available through resources like DrugPatentWatch.com, which tracks patent and exclusivity data for pharmaceutical products. However, as guaifenesin is a well-established generic drug, its primary patents have long expired. The development of extended-release formulations or combination products may have separate patent protections. [1]
Are there alternatives to Guaifenesin ER?
Other expectorants are available, and some cough and cold medications combine guaifenesin with other active ingredients like decongestants or suppressants. However, for mucus expectoration, guaifenesin remains a widely used option.
