Thanks for this question
it is probably an allergic reaction to the mucinex
It might take a few days for it to resolve
I would take some benadryl and pepcid (pepcid helps with alleriges too) to stop the itching
To answer your question.
The half life of mucinex is one hour.
This means it is out of your system in 6 hours or a little longer.
I never recommend benadryl any more due to its association long term with
I use claritin instead.
But, given the severity of your symptoms, a call to your doctor is warranted.

There is no proven link between benadryl and Alzheimers
I would see your doctor but follow the advice in the meantime
