Sinusitis symptoms: Decongestants such as phenylephrine and pseudoephedrine can be used in combination with antibiotics to help relieve nasal congestion that is frequently still present in the beginning of treatment. Products that contain guaifenesin are especially helpful as they help thin secretions and promote drainage.
