Guaifenesin is an expectorant. It works by thinning and loosening mucus in your airways, clearing congestion, and making it easier for you to cough out through your mouth.

Guaifenesin 1200 mg extended release is mainly used to treat coughs and congestion caused by common cold or flu. Guaifenesin 1200 mg is not used to treat an ongoing cough from smoking or long-term breathing conditions (such as chronic bronchitis, asthma, emphysema) unless directed by your doctor.

Guaifenesin 1200 mg starts to work pretty quickly. Most people can expect to feel its full effect within 30 minutes of taking; however, for some, it can take up to 2 days before full effects are seen after first taking guaifenesin 1200 mg.

For adults and children 12 years of age and older, you may take 1 tablet of guaifenesin 1200 mg every 12 hours. But do not exceed 2 tablets within 24 hours.  Do not use this product in children under 12 years of age.

While guaifenesin 1200 mg and guaifenesin 600 mg are the same ingredient, the strength is different so the dosing instructions and uses are different between guaifenesin 600 mg vs 1200mg. For adults or children 12 years of age or older, if guaifenesin 600 mg does not provide you with adequate symptom relief, you may try taking guaifenesin 1200 mg every 12 hours. However, if a cough persists for more than 7 days, comes back, or occurs with fever, rash, or persistent headache, stop using this product and consult your doctor immediately.

Curist Mucus Relief and Mucinex 1200 mg are two brands that both contain the same medicine at the same strength, guaifenesin 1200 mg. Guaifenesin treats mucus and congestion caused by ailments like the common cold or flu. Unlike Mucinex, Curist Mucus Relief does not include any color dyes and is less expensive.

Unfortunately no, guaifenesin is an expectorant and does not help for a dry cough. Guaifeneisn helps loosen mucus so you can have more productive coughs but it does not stop coughing. It works by increasing the water content of the mucus, thinning it out, and making your cough more productive (aka wet cough). Dry cough, on the other hand, does not produce mucus and it can be treated by cough suppressants such as dextromethorphan.

Yes, Curist Mucus Relief (guaifenesin 1200 mg) is both dye-free (the tablets are all white in color) and salicylate-free.

Yes, there are generic versions of Mucinex which contain the same medicine, guaifenesin. For instance, both Mucinex 1200 mg and Curist Mucus Relief Guaifenesin 1200 mg have the same strength of guaifenesin (1200 mg), so the mucus relief is the same between the Mucinex 1200 mg and Curist Mucus Relief 1200 mg, but Curist is much less expensive and dye-free.

As an expectorant, Mucus Relief (guaifenesin 1200 mg) does not commonly cause serious side effects but it can cause dizziness, drowsiness and rash. If any of these effects persist or worsen, consult your doctor or pharmacist promptly.
