Which means combining it with a decongestant only defeats the purpose. Besides, phenylephedrine is a placebo for 95% of people. Yes, it only works on 5% of the population. Pseudoephedrine is much more effective, but access is usually controlled and monitored due to the methamphetamine production industry. You should only want to use a decongestant to sleep.
This is the original, with no decongestant. It works as it was always intended to work. And it works well.
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.
