Key takeaways
Zyrtec-D (cetirizine/pseudoephedrine) and Mucinex Sinus-Max Severe Congestion and Pain (acetaminophen/guaifenesin/phenylephrine) are both over-the-counter medications used to relieve symptoms of allergies and the common cold, but they work differently. Zyrtec-D combines an antihistamine (cetirizine) and a decongestant (pseudoephedrine) to clear sinuses and reduce inflammation caused by allergies, making it effective for sneezing, itchy or watery eyes, and nasal congestion. In contrast, Mucinex Sinus-Max includes a pain reliever (acetaminophen), an expectorant (guaifenesin), and a decongestant (phenylephrine) to address sinus congestion or pressure, headaches, minor aches, and mucus in the lungs. Zyrtec-D is typically taken every 12 hours, while Mucinex Sinus-Max is taken every 4 hours. Zyrtec-D can cause trouble sleeping and may raise blood pressure, especially in people with heart conditions. Mucinex Sinus-Max has a risk of liver damage (if taken in excess) and can also raise blood pressure. Both medications should be used with caution if you have certain health conditions or are taking other medications.
