While coughing, as the air is forced up through the passageway which has narrowed due to the swollen voicebox or larynx, it produces a sound which is similar to a  barking seal. Croup is not a very serious condition and can be treated at home as well. There  are mainly 3 types of croups:

  • Allow your kid to inhale the cool air during the night by opening a door or window
  • OTC(Over The Counter) medications such as acetaminophen or ibuprofen should be given to your children for treating the fever.
  • The coughing can be easily treated by using warm water since it loosens the mucus in the vocal cord or larynx.
  • Prop up your kid’s head using extra pillows while he or she is sleeping. This should be avoided if your kid is lesser than 12 months or 1 year old.
  • Oral syrups containing glucocorticoids are dexamethasone and prednisolone are given to your kid.
  • Intravenous (IV) or Intramuscular (IM) injections containing Dexamethasone are also used in the case of the treatments for the kids who are frequently vomiting and can’t keep liquids down.

  • Humidifying of the air that is being breathed in by your kid is very necessary.
  • In the case of dehydration in your child due to fever or fast-paced breathing, IV(Intravenous) fluids are used for treating it.
  • Constant monitoring of oxygen levels, heart rate, skin colour is needed. And the level of the alertness is also evaluated to understand the status of the child i.e. whether your kid is responding to the treatment or not.
  • A breathing tube is placed in the throat of your kid in the case of severe Croup. Less than 1% of children are seen in the emergency department require this treatment.
  • The most commonly used medication for the treatment of moderate and severe Croup consists of Dexamethasone. It provides a long-lasting treatment. It reduces the swelling of the larynx within 6 hours. It can also be used as oral syrup as well as an IV(Intravenous) or Intramuscular(IM) injection. 
  • A nebulizer is used for giving epinephrine(also known as adrenaline) to your kid if he or she is suffering from moderate or severe Croup. It works for a very short period and can be given every 15 minutes to 20 minutes to your kid in the case of severe symptoms.
