It’s worth going to the drugstore if your cough won’t let you sleep.

This ingredient instructs the part of your brain that controls coughing to stop, which can help you get some rest if your coughing is interrupting or preventing sleep.
He also recommends nasal anti-inflammatory steroid sprays like Flonase, Nasacort, or other allergy medications, which may reduce coughing.

- A loud cough that sounds like a seal’s bark
- Producing blood or bloody mucus when you cough
- A cough that affects how you breathe
- A cough that lasts longer than three weeks
- Breathlessness
- A body temperature of 100.4 degrees F (38 degrees C) or higher that lasts longer than 48 hours
