What are the best nonprescription cough medicines?
Dextromethorphan (DM) and codeine are commonly found in nonprescription cough and cold medicines. Both are good, but codeine remains the gold standard. It’s usually behind the counter, and it requires a prescription in some states. Codeine is prone to side effects, including stomach distress. It’s important to follow the directions and report any side effects to your physician or pharmacist.
