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.
