The two active ingredients in Advil Cold and Sinus are 200 milligram ibuprofen and 30 milligram pseudoephedrine HCI, according to the product label viewable on the Advil website. Advil Cold and Sinus caplets also have a number of inactive ingredients that do not contribute to symptom relief.
Advil Cold and Sinus caplets work to relieve symptoms associated with the common cold and flu, such as headache, sinus pressure, fever, nasal congestion, and minor aches and pains, notes Advil. Ibuprofen is a nonsteroidal anti-inflammatory drug that acts as both a pain reliever and a fever reducer, while pseudoephedrine HCL relieves nasal congestion. Advil Cold and Sinus is a non-drowsy formula that allows cold sufferers to get relief for symptoms throughout the day.
Sinus pain and pressure occurs because of a combination of nasal swelling due to inflammation and increased mucus, both of which block airways, explains Advil.com. The active ingredients in the medication work to reduce swelling and clear mucus, all while relieving pain and fever. The recommended dosage for a person aged 12 or older is one to two tablets every four to six hours while symptoms persist. An individual should take no more than six caplets in a 24-hour period, unless directed by a doctor.
