## Description

These expectorant tablets relieve chest congestion and thin and loosen mucus, making your coughs more productive.

Review: Good Price, Works For Me - If you’ve done a review on desertcart then you know that they ask questions like “how is the flavor?” I’ll tell you how the flavor is….awful. Do not ever bite one of these tablets. If you’re brave, you can try to swallow one whole. I usually cut them in half. Value for the money….Terrific. They may cost a few dollars less at Costco, but who wants to go to Costco. The location in S Ogden, UT, is so busy that I dread going there. I have resorted to buying some of their products on desertcart. Good value and works just as advertised.
Review: Only thing so far that helps with my chronic gagging and coughing on phlegm - I had this new and sealed large bottle in my cabinet and was thinking of throwing it because I have increasingly bad reactions to Nyquil, Benadryl (hyperactive bladder reaction, dizziness). But I notice it was not the same ingredient so kept it. Just a couple days ago I tried it for my wretched chronic allergy cough due to phlegm from lungs and post nasal drip. Miraculously it worked! I can't tell you what a blessing it is to have any relief at all. I take one pill with a large glass of water every four hours. It does wear off after four hours, so take some with you. It does not seem to have any side affects either. It is also reasonably priced. I highly recommend if you've tried everything with no success. A violent allergy cough can be debilitating and is not solved for very long with cough medicine, even the prescription kind.

## Questions & Answers

**Q: Does this have any other active ingredients other than Guaifenesin?**
A: I am reading directly from the bottle and it reads: Active ingredient in each immediate-realease tablet :Guiafenesin 400mg  ................Expectorant

**Q: are these the 4 hr. dose or the 12 hr.?**
A: 4 hours @ 400mg.  The 12-hour versions have 1200mg in slow release pill.Same with cough suppressant Dextromethorphan Hbr; 4 hours @ 20mg, and slow release 12hours @ 60mg.  True for all OTC pharma -  12-hour versions are 3x "normal" 4-6 hour ingredients at also about the same unit price (3x normal).

**Q: What is 400mg guaifenesin 20mg dexdrmedthorpan hbr?**
A: As others said, guaifenesin, thins mucus so the body can expel it easier; Dextromethorphan Hbr is an OTC cough suppressant.  You need a cough suppressant to stop coughing so your lungs can heal or get sleep.   It depends on your condition whether an expectorant or a suppressant is needed.  I suppose if your lungs are stuffy, but not coughing, this (Gua. ..  only) is OK.  But if your have a hacking cough, your condition needs a doctor to listen to your lungs and a suppressant is needed (like prescription codeine).The dosage you cited is 4-6 hours; 12-hour version has triple the active ingredients in a slow release pill (1200mg Guaif, and 60mg Dex Hbr).Generally, every version is "maximum strength", so the only difference is 4 hour or 12-hour version.

**Q: What was the expiration date on the bottle you received?  Was it fresh?**
A: The two bottles we are using now expire July 2016 and the two new ones expire August 2016. We have been using this brand for two years now and have never had a problem and they have always worked for us using our Doctor's guidelines for allergies and colds to dry us up and keep our nasal passages clear.

### ⭐⭐⭐⭐⭐ Only thing so far that helps with my chronic gagging and coughing on phlegm
*by M***M on December 29, 2018*

I had this new and sealed large bottle in my cabinet and was thinking of throwing it because I have increasingly bad reactions to Nyquil, Benadryl (hyperactive bladder reaction, dizziness). But I notice it was not the same ingredient so kept it. Just a couple days ago I tried it for my wretched chronic allergy cough due to phlegm from lungs and post nasal drip. Miraculously it worked!

### ⭐⭐⭐⭐⭐ These worked great for me (were COPD-friendly) and helped end my bout with Bronchitis
*by M***N on December 4, 2014*

I have been using this 3 times within the last 5 ears. The prescription version is 600mg (M*U*C*I*N*E*X), and this is 400mg per tablet. It is not fast-working as it takes at least three weeks for the phlegm to loosen up and get out while 2 in the morning and 1-2 at night "Every-other-day". Oftentimes when we are in need, we expect immediate results. This is one that has to be incorporated over a period of time to see results. I have allergies to things such as vehicle emissions, dust, pollenation, grass-cutting, furry pets, etc. I have been using this for 2 and a half months and I am pleased with this product. In 2010 I have a bad bout with bronchitis and this helped me to get rid of fluids that might of led to pneumonia. Also, you have to exercise your lungs by taking deep breaths in and doing "hoo", "huuh", and "haww" short bursts outward. Sort of forcing my lungs to work. And keep your nasal passages clear by blowing your nose frequently. This may work for some, and others not. I am just sharing my experience with this.
