Sinus congestion occurs when the lining of the sinus cavity becomes inflamed and swollen. When the sinuses are swollen, it can bring on symptoms like stuffy nose and/or pressure or pain around the forehead, in-between your eyes, on either side of your nose, or in your upper mouth. Like nasal congestion, it is often caused by allergies or a cold virus. Sometimes, sinus pressure can also lead to a sinus headache as a result of mucus built up in the sinuses.

Decongestants can also help relieve sinus congestion, working in the same way to provide symptom relief in the sinus cavities. If you are also experiencing sinus pain, look for an OTC medicine with a pain reliever, like acetaminophen, in it. Vicks has plenty of OTC multi-symptom medicines available, so be sure to check each label for the active ingredients, so you can pick a product that addresses more of your symptoms.
