Cough
"I was traveling and started having dry, allergy-related cough. Trying to suppress it long enough to give a presentation and Delsym worked perfectly. But as others noted, started to have diarrhea. I didn&#039;t connect it right away to Delsym, because when traveling everything is disrupted. Now home, everything had mostly cleared up and took the last dose last night, and sure enough diarrhea back today. I take no other meds."
