Sinupret® is an excellent sinus remedy, with no side effects. While standard decongestant products seem to clear nasal passages pretty well, they don't do much for clearing the sinuses - and they can keep you awake or give you the jitters. But if you take Sinupret®, your nasal passages clear, and gradually, the accumulated mucus in the sinuses goes away. Sinupret® seems to operate like a nutrient rather than a medicine, in that the best effects develop over day or two, rather than a quick yanking down of a specific symptom followed by a rebound, as in other OTC products or even prescription drugs. That means that some sort of healing process is taking place, rather than just a palliation of symptoms.
