Cough : When to see a doctor?

  • Coughing up thick, greenish-yellow phlegm
  • Wheezing
  • Experiencing a fever more than 100 F (38 C)
  • Experiencing shortness of breath

Seek emergency care
Seek emergency care if you or your child is:

  • Choking
  • Having difficulty breathing or swallowing
  • Coughing up bloody or pink-tinged phlegm

Self-care measures
To ease your cough, try these tips:

  • Suck cough drops or hard candies. They may ease a dry cough and soothe an irritated throat. Don't give them to a child under age 3, however, because they can cause choking.
  • Moisturize the air. Use a vaporizer or take a hot, steamy shower.
  • Drink fluids. Liquid helps thin the mucus in your throat. Warm liquids, such as broth, tea or lemon juice and honey in warm water, can soothe your throat.
