Compare Dayquil vs. Advil Cold and Sinus

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Acetaminophen/dextromethorphan/phenylephrine (Dayquil) and ibuprofen/pseudoephedrine (Advil Cold & Sinus) are both over-the-counter medications used to relieve symptoms of the common cold and flu, such as headaches, body aches, and nasal congestion. However, they have some important differences. Dayquil combines an analgesic, a cough suppressant, and a decongestant, while Advil Cold & Sinus combines a nonsteroidal anti-inflammatory drug (NSAID) and a decongestant. Dayquil is available in both pill and liquid forms and is typically taken every 4 hours, while Advil Cold & Sinus is taken every 4 to 6 hours and comes as a caplet. Dayquil can cause side effects like stomach upset and nervousness, whereas Advil Cold & Sinus may lead to difficulty sleeping, nausea, and stomach upset. Both medications should not be taken with monoamine oxidase inhibitors (MAOIs). Additionally, Dayqui should not be taken with alcohol, while Advil Cold & Sinus can increase the risk of stomach bleeding and heart problems.
