What meds have guaifenesin?

What cough medicines contain guaifenesin?

Guaifenesin is a common expectorant, used to loosen mucus and make it easier to cough up. Many over-the-counter “cough and chest congestion” products include it, usually combined with other ingredients like dextromethorphan (a cough suppressant) or phenylephrine (a decongestant).

Because the exact list depends on the brand and strength sold in your country, the most reliable way to identify what’s available is to check the active ingredients on the label for “guaifenesin.”

How to find guaifenesin on a drug label

Look under “Active ingredients” for guaifenesin (sometimes written as “guaifenesin” or “guaifenesin, USP”). If it’s present, the product is typically described as:
- an expectorant,
- or “cough” and “chest congestion” medicine intended to loosen mucus.

Common product types where guaifenesin shows up

You’ll most often see guaifenesin in:
- Expectorant syrups
- Combination cough syrups (mucus + cough suppression)
- Some extended-release cough preparations

If you tell me your country and symptoms, I can narrow it down

What country are you in, and are you looking for (1) syrup, (2) tablets/capsules, or (3) something for nighttime cough with less coughing? Also tell me whether you want a product that includes only guaifenesin or one that’s combined with other ingredients.
