Croup

Definition:  Croup is a bad cough usually caused by a viral infection in and around the larynx (voice box).  It usually is accompanied by cold symptoms and possibly by fever, and causes laryngitis and a tight cough that sounds like a seal’s bark.  In severe cases, you may hear a harsh, raspy sound as your child breathes in.  This is called stridor.  Some people describe stridor as a crowing noise.  

Croup usually lasts 5-6 days and becomes worse at night.  Your child is contagious for about five days, but can return to school or day care after the fever is gone.

Home Care:
  1. Dry air makes croup worse.  Run a warm mist humidifier in the bedroom.
  2. For coughing spasms in children older than 4 months, give warm fluids to relax the airway (warm apple juice or caffeine-free tea).
  3. For mild cough, children 12 months or older can take 2-5 mL of corn syrup, which may thin the mucus secretions and loosen the cough.  However, this is less helpful than warm mist.  Children age 6 or older can suck on cough drops or hard candy.
  4. For severe cough, you may use dextromethorphan (DM), which is present in most over-the-counter cough syrups.
  5. If croup is accompanied by elevated temperature over 102°F, you may give acetaminophen or ibuprofen.
  6. It may be worthwhile to sleep in the same room with your child for a few nights; croup can suddenly become severe at night.
  7. Your child should avoid tobacco smoke; passive (second-hand) smoke makes coughs much worse.
  8. For stridor, try having your child inhale warm mist from a wet washcloth, a warm mist humidifier, or a foggy bathroom for 20 minutes.  If that fails, inhale cool air from breathing near an open refrigerator for a few minutes, or by taking your child outside for 10 minutes.
Contact our office urgently if:
  1. Your child is less than 12 months old and has difficulty breathing not helped by cleaning the nose.
  2. Your child is older than 12 months and has difficulty breathing when not coughing.
  3. Your child’s ribs are mildly pulling in with each breath.
  4. Stridor doesn’t respond to 20 minutes of warm mist or cool air.
  5. Your child can’t bend his/her neck forward.
  6. Your child has sudden onset of stridor and fever after two days of croup.
Contact our office during regular hours if:
  1. Stridor attacks do not respond to mist.
  2. Your child has continuous (non-stop) cough.
  3. Your child is less than 3 months old and has had a cough for more than 3 days.
  4. Your child also has an earache (pulling at ears, fussy).
  5. Your child has had a barky cough for more than 5 days.
  6. Croup is a frequently occurring problem for your child.
