  • Maximum Strength OTC to aid with Chest Congestion
Size: 42 Count (Pack of 1) Configuration: Release Tablets
There are times that I have bad allergies. An allergist (doctor) put me onto Mucinex (more precisely, guaifenesin, the active ingredient). For me, it helps loosen the "gnarly stuff" so I can expel it, which in turn prevents build-up from causing more severe symptoms or even infection. Mucinex is my go-to for OTC variant of the drug, because they maintain known quality standards. It's the company's "flagship" for the guaifenesin drug group. This particular label is the Maximum Strength with Extended Release. I want to make clear what Mucinex is not. This is NOT intended as a cough suppressant, a replacement for asthma medicine, nor one of the "fix all symptoms" flu reliefs. It can help alleviate some of the chest congestion of a flu, and it might help prevent secondary infections. (Ask your medical provider if that's best for you--or your mom. :) ) Note: This specific product has no decongestant. You can buy two other forms of Mucinex with decongestants, usually packaged with DM on the label in the US. ... show more
