The lowest-cost alternatives to Guaifenesin-Codeine are OTC medications that contain dextromethorphan (a cough suppressant) and guaifenesin. If these work, it may be both safer and less expensive to use them rather than Guaifenesin-Codeine. Another possibility is to combine over-the-counter guaifenesin with a prescription antitussive such as hydrocodone or benzonatate. The price may be lower than Guaifenesin-Codeine, but these drugs have their own risks. Ask the prescribing healthcare provider for medical advice. Both guaifenesin and prescription cough suppressants can be purchased for as much 80% off the retail price with a SingleCare discount card.
