When trying to relieve sinus pressure and nasal congestion, look for a decongestant. A decongestant will shrink the mucus membranes that have swollen in your sinuses. This will help the trapped mucus drain out.
Some Mucinex® products contain the decongestant pseudoephedrine. Some Mucinex® liquids contain phenylephrine, and Mucinex® nasal sprays contain oxymetazoline.
Oxymetazoline is only found in nasal sprays. It’s what is known as a “topical decongestant.” That means it needs to be applied to the affected areas in the nose rather than taken as a pill or liquid.
Products containing pseudoephedrine can be found behind your pharmacist’s counter.
Use as directed.
