Can I take Allegra and Tylenol Sinus together?

Tylenol Sinus (acetaminophen, pseudoephedrine) may have several different formulations. If you have the pain/decongestant combination, there are no direct drug interactions with Allegra (fexofenadine).

If you have high blood pressure or heart disease, please speak to your doctor before taking any oral decongestant.

Limit your daily total amount of acetaminophen (Tylenol) to not more than 4000mg. Take the Tylenol Sinus only as needed.
