Guaifenesin brand name?

What brand names does guaifenesin go by?

Guaifenesin is sold under many cough-syrup and expectorant brand names in different countries. Common brand-name examples include Mucinex and Robitussin (often in specific formulations that combine guaifenesin with other ingredients).

How do I find the exact brand for my product?

The surest way is to check the active ingredient on the label: look for “guaifenesin” in the Drug Facts/Active ingredient section. Brand names can vary by country, and some products mix guaifenesin with dextromethorphan or other cough/cold ingredients.

Is guaifenesin ever sold generically?

Yes. Guaifenesin is widely available as generic and store-brand “guaifenesin expectorant,” so you may see it sold without a branded name.

What if my bottle doesn’t say “guaifenesin”?

Some cough syrups use different expectorant ingredients or use combination “cough and cold” formulas. If you share the product label text (or a photo of the active ingredients section), I can help identify whether it contains guaifenesin and what the brand/formulation likely is.
