Croup

Your child has been diagnosed with croup.

We know this can be a stressful time with lots of information from healthcare providers. It can be difficult to absorb everything.

We hope the following pages will be helpful in providing you with the education and resources you need to support your child from home.

What is Croup?

Croup is an acute respiratory illness most common in children between the ages of 6 months and 3 years.

It is due to inflammation of the larynx (voice box) and trachea (windpipe) most often caused by a viral infection. Viruses that can cause croup include parainfluenza, influenza, RSV and SARS-CoV-2.

Symptoms of Croup

The main symptom of croup is a harsh, barking cough that can sound like a seal barking.

Other symptoms might include:

  • fever
  • runny nose
  • hoarse voice
  • stridor (high pitched sound when the child breathes in)
  • difficulty breathing

Hospital Care

If you have been seen by a medical professional, they may have treated your child with medications. Click below to learn more about these medications.

A. Epinephrine

Epinephrine helps to reduce inflammation in the airways and improve breathing. It is usually given via a nebulizer or puffer in the emergency department. It works quickly to help improve symptoms but does not provide long-lasting relief.

B. Dexamethasone

Dexamethasone is a steroid that acts to reduce inflammation. In croup, it acts to reduce inflammation in the airways to help improve breathing. Dexamethasone usually takes a few hours to start to work but lasts over 24 hours. Therefore, it helps provide long-lasting relief and generally only one dose is required to treat croup.

If your child was prescribed this medication, please follow the instructions of the doctor and if you have any questions, speak to your doctor or pharmacist.

Help your child stay hydrated

As with other viral illnesses, it is important to ensure your child remains well hydrated by offering fluids containing not only water but sugar and electrolytes (e.g., breastmilk or formula in infants, electrolyte drinks in older children) WebMD - Treating Dehydration in Children

Help with fever and discomfort

To help reduce fever and alleviate discomfort, you can give your child acetaminophen (Tylenol) or, if they are over 3 months old, ibuprofen (Advil), so long as your child does not have allergies or other reasons not to take these medications.

Note: fever in infants under 4 weeks of age is a medical emergency and these children should be seen in their local emergency department. Caring for Kids - Fever and temperature taking

Unless your doctor advises you otherwise, give the dose recommended on the medication package. Safe Acetaminophen Dosing for Infants and Children Mount Sinai - Ibuprofen Dosing for Infants and Children

Help with your child's cough

Cold, humid air can help reduce inflammation of the windpipe. Parents may consider turning on the shower and having the child breath in the humid air or exposing the child to cold air from outside, being careful that the child's body temperature remains normal Mayo Clinic - What to do if your child has croup

Does my child need antibiotics?

Antibiotics are not used to treat viral infections, like croup.

Viruses and bacteria can both cause infection but are different bugs. Bacteria can be killed using antibiotics. Viruses cannot be killed by antibiotics.

Although antibiotics are not used to treat croup, some children may have other infections requiring antibiotics such as an ear infection. Please follow the advice of your physician and if you have any questions, speak to your doctor or pharmacist.
