Daddy's Bug

This is the best medicine for a cold. It starts knocking out the chest congestion and nasal congestion in about 2 days.

Pricing

Great price if it is compared to CVS or Walgreens. Multiple dose convenience for individuals that need to take this medication on a daily basis.

Mucinex DM knocked out COVID19 coughing

I had a lingering COVID19 cough for 8 weeks. Went through 2 bottles of cough medicine and was still coughing. It wasn't until I changed to Mucinex DM that I finally had relief. It only took 2 doses before I finally got past the coughing!!!

Worked Well for Us

There was a horrible bug going around with the start of the new school year. (You would think people would have learned...) MucinexDM was suggested by our family doctor to combat the symptoms, and worked well.

New policy is not worth rhe price.

I hate that I will be canceling my membership when it’s time to renew, due to your new policies. I live an hour away and , with my club membership, I have enjoyed free shipping. Now, I will be charged for shipping unless I spend $50.00 on each order. That is not worth paying for a Club membership.

Works ok but not great

It works okay to calm a cough but I don't find it helps much for chest congestion.
