Implement a Therapeutic Interchange for Obredon
Shortages of Rx cough meds (Tessalon, Tussionex, etc) mean more questions about treating cough in adults due to respiratory infections.
It's tempting to recommend a product with dextromethorphan and/or guaifenesin. But there's not much evidence they work.
Instead, recommend adults try an oral decongestant and FIRST-generation antihistamine (brompheniramine, etc). These help reduce the postnasal drip that can trigger coughs. Second-generation antihistamines (loratadine, etc) are NOT effective.
