The two active ingredients in Sinutab Non-Drying are guaifenesen and pseudoephedrine hydrochloride. Guaifenesin is classified as the expectorant and it helps loosen phlegm from the throat and chest, which makes coughing productive. Pseudoephedrine is classified as the nasal decongestant and it helps to decrease swelling in the nasal passages and constrict blood vessels. Sinutab Non-Drying Maximum Strength contains 200 mg of guaifenesin and 30 mg of pseudoephedrine per caplet.

Sinutab Sinus Caplets
