There is limited evidence to support the efficacy and safety of Clofera in the management of cough and nasal congestion associated with the common cold; therefore, it should not be recommended. Clofera is formulated to contain no dyes, sugar, alcohol, or gluten and will be marketed as an option for patients who need to avoid these substances. Other formulations that are available for patients with sensitivities include Scot-Tussin Diabetes CF(dextromethrophan) (dye-free, alcohol-free, gluten-free, and kosher), Robitussin Cough Control Diabetic(dextromethorphan/guaifenesin) (dye-free, sugar-free, alcohol-free, does not contain sorbital or fructose and is low in sodium), and Diabetic Tussin (dextromethorphan/guaifenesin) (dye-free, sugar-free, alcohol-free, does not contain sorbital, or fructose and is low in sodium).
