Miscelleneous
How it works
Rex Syrup is a combination of Guaifenesin, Terbutaline, Bromhexine and Menthol. Guaifenesin works by reducing the thickness of mucus in your air passages; this makes it easier to cough out the mucus and clear your airways. Terbutaline works by relaxing and opening the blocked air passages leading to your lungs. Bromhexine works by thinning the mucus in your airway and promoting mucus clearance. Menthol causes a feeling of coolness and also reduces itching and pain.
