Phenylfenesin is a guaifenesin, phenylephrine and phenylpropanolamine combination. Guaifenesin belongs to a group of medicines known as expectorants. It works by thinning mucus to make breathing easy. Guaifenesin enhances lubrication of the respiratory tract, thereby increasing the removal of mucus. Phenylephrine and phenylpropanolamine belong to a class of medicines known as decongestants. Both work by shrinking blood vessels, an action that reduces the swelling of the mucous membranes in areas such the sinuses and the nose. Phenylfenesin should be taken with caution if you have diabetes, glaucoma or high blood pressure. You may require special attention or dosage adjustment during treatment if you have these conditions.
