Ordering this from Sams is a much better price then I have paid in any other store. Another perk is fast delivery and I dont have to drive an hour to shop.

I suffer with allergies and my ENT recommended to use a mucus relief product. I was using the name brand until I found Members Mark and I have notice any difference in how it works from the name brand.

I like the dosage at 1200 mg and the 12 hour interval. So many others are down to 200 mg every 4 hours. Why bother? When you're not feeling well, you want it to be effetive and not the short intervals. Well done Members Mark!

These work great!! My father has COPD and allergies, living in Indiana with the weather chaning every 20mins. These are great for my Dad, also for anybody who has a cold. Great value and works great!!

12 hour extended release guaifenesin, the same medication, and Robitussin and Mucinex. It's an expectorant that thins out your mucus. Just be sure to drink lots of water great price, better than the namebrand with more tablets.

I switched from brand name Mucinex to this and used it twice daily for 2 weeks. This Member's Mark generic Mucinex was like taking nothing. I have been taking brand name Mucinex 1200mg twice daily for over 2 years. Since then, my sinus headaches have reduced from 3 per week to 3 per year! Trying to save some money, I tried this generic. I am not against generics and use them all the time. It took me about 2 weeks to realize why I was waking up with nasal stuffiness and sinus headaches and having to take Sudafed (which can raise blood pressure and blood sugar) 2 to 3 times during the day. I quit taking this and switched back to Mucinex and my sinus headaches are gone! Don't waste your money on this generic. It's not worth it.

I have had a lot of excessive mucus in my throat that I am not easily able to bring up and it makes it difficult to talk. My Pulmonary Doctor recommended that I take Musinex to help with this problem. I purchased the Members Mark Mucus Relief Extended Release Tablets and have been taking them for about a week. These seem to be working better than I expected and I am not having mucus problems anymore. I am very happy with this product

I see mixed reviews below - either great or terrible. Luckily I fall on the great side. These work as well as Musinex for me at 1/2 the price. FIRST Check with your doctor or pharmacist - I did - and found some need a bit more meds to cover the time. I take an extra 400 mg along with 2-1200 mg per day to cover the 24 hours.

The active ingredient may be the same as in name brand mucinex, but sometimes when the active ingredient is mixed differently with the inactive ingredients, u just don't get the same drug! This is one of those examples. This medication does absolutely nothing & I've been taking mucinex for well over a decade. Do not buy! Stick with name brand. Sam's needs to stop carrying this & go back to the drawing board.

Work just like the name brand for less.
