Mucinex Side Effects

Before reading this article please understand that this list may not contain every single possible side effect of Mucinex. This is because some instances may have not been documented or reported. Make sure to talk to a doctor for medical advice pertaining specifically to your needs.

If you didn’t already know, the main and most important ingredient in Mucinex is guaifenesin. It is an expectorant that allows for the loosening of mucus in lungs. Apart from Mucinex, it is also the base ingredient in medications such as Robitussin and MucaPlex. Thus, guaifenesin side effects are the same for most of the aforementioned medications.

Generally, the Mucinex expectorant is tolerated well by a healthy person.
