Sandy asked
is Mucinex DM effective for sinus congestion?
Answer
Mucinex DM likely isn't your best option for treating sinus congestion. Mucinex DM contains the following two active ingredients:
- Guaifenesin
- Dextromethorphan
Guaifenesin is an expectorant, which helps to thin and loosen mucus, easing expectoration. Guafenesin is most commonly used for chest congestion and for thick mucus that is hard to clear from the airways.
Dextromethorphan is an anti-tussive, used to treat a dry, unproductive cough.
A better option for sinus congestion and pressure would be to use a decongestant, either Sufafed (pseudoephedrine) or Sudafed PE (phenylephrine). These are decongestants, which will relieve sinus pressure and sinus congestion. Specifically, decongestants produce vasoconstriction, which shrinks swollen nasal mucous membranes, reduces excess blood in the tissues, increases drainage of sinus secretions and decreases nasal airway obstruction.
