What can I do to prevent or relieve the symptoms of chronic cough?

To prevent chronic cough:

• Quit smoking, or don't start smoking, since this is the most common reason for chronic cough.
• Avoid contact with anyone you know who may have bronchitis or pneumonia.
• Eat fruit and foods that contain fiber. Research suggests that a combination of fiber and flavonoids found in fruit may prevent chronic cough.

To relieve the symptoms of chronic cough:

• Drink plenty of water (at least eight 8-ounce glasses a day).
• Gargle with warm saltwater to help remove any mucus.
• Inhale steam.
• Avoid inhaling dust, smoke or other pollutants as much as possible.
• Use extra pillows at night to prop up your head and upper body.
• Try cough lozenges.
• Try over-the-counter cough medicines that contain guaifenesin and/or dextromethorphan.
