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.
List of Common Side Effects:
- dizzy feeling (lightheadedness)
- headache (feeling of discomfort or pain in your head)
- rashes (an area of your skin that changes in appearance and/or texture)
- upset stomach (discomfort in stomach)
- vomiting (puking, throwing up)
- nausea (feeling like you need to vomit)
- anaphylactic reaction (a serious allergic reaction)
If you are allergic to Mucinex (aka guaifenesin), side effects can potentially include:
- trouble breathing
- swelling or puffing
*Seek immediate medical help if any of these occur.
If you have experienced a side effect not listed here, please report it to the Food and Drug Administration.
