Why Albuterol Is No Longer Used for Bronchiolitis

Bronchiolitis is a lower respiratory tract infection that commonly occurs in children under 2. It is usually caused by the respiratory syncytial virus (RSV), which triggers inflammation of the smaller air passages (bronchioles). The inflammation causes the partial or complete constriction of the bronchioles, resulting in wheezing and shortness of breath.

Bronchiolitis is the leading cause of hospitalization in infants and young children. Since there is no cure for bronchiolitis, treatment is primarily aimed at alleviating symptoms of fever and breathing difficulties. If hospitalization is required, the treatment may also include supplemental oxygen and intravenous fluids to prevent dehydration.

In the past, the drug albuterol was commonly used in hospitals to help the child breathe. Albuterol is classified as a bronchodilator that works by relaxing muscles in the air passages. It is available in inhaled, oral, and injectable formulations and is commonly prescribed to people with chronic obstructive pulmonary disease (COPD) and asthma.

While it would seem reasonable to use albuterol in cases of severe bronchiolitis, updated guidance from the American Academy of Pediatrics (AAP) now recommends against its use.

Why the AAP Advises Against Albuterol

In their updated 2014 recommendations, the AAP acknowledged that albuterol can provide transient relief in children with bronchiolitis in the same way that it does asthma. However, the actual effectiveness of the drug in this scenario was largely subjective.

Research published in 2013 has shown that the use of albuterol in hospitalized children did nothing to improve outcomes or reduce hospital stays. Moreover, the AAP recommends against other treatments commonly used in the past, including nebulized hypertonic saline, systemic corticosteroids, antibiotics, and chest physiotherapy.

When to Go to the Hospital

Bronchiolitis in children will usually develop after two to three days of the common cold. It typically starts with nasal congestion and discharge, a mild cough, and a fever over 100.4 F.

If the infection progresses and the lower air passages are involved, the condition can become serious and lead to symptoms of:

  • Rapid breathing
  • Wheezing
  • Persistent coughing
  • Difficulty feeding
  • Gaps in breathing (apnea)

A parent will know that it's time to take the child to the emergency room if the wheezing lasts for more than seven days or progresses to grunting.

Another indication that a trip to the ER is warranted is if a child is using the muscles between the ribs or at the neck to take in breaths, is belly breathing (meaning the belly is going up and down severely with each breath), or cannot complete sentences without taking breaths in-between.

If the child weakens considerably and has a bluish tinge to the skin or lips (cyanosis), the parent should consider it a medical emergency and call 911.

Current Hospital Recommendations

Approximately 2-3% of all children will require hospitalization for bronchiolitis. Treatment involves the monitoring of vital signs and supportive care based on the child's condition and symptoms.

Supplemental oxygen may be needed for children who are unable to catch their breath. This is usually done by placing a tube, called a nasal cannula, under a child's nose or by using a face mask. For infants, an oxygen headbox may be used.

If the child is unable to eat or drink, either because the respiratory rate is too fast or breathing is severely impaired, fluids and nutrition may need to be delivered intravenously (into a vein).To prevent the spread of the virus, the child would be isolated from siblings and other children until the condition is fully resolved.

Most children hospitalized for bronchiolitis are well enough to return home after three to four days.

Frequently Asked Questions

  • Is Albuterol used for a COVID-19 cough?

    No, Albuterol is not used for a COVID-19 cough. In October 2020, the Food and Drug Administration (FDA) approved the use of a antiviral injection named Veklury (Remdesivir) to treat COVID-19 symptoms. The injection is administered by a healthcare professional for adults and children 12 years or older weighing at least 88 pounds.

  • How often can you use Albuterol?

    How often you can use Albuterol will depend on the instructions given by a healthcare provider. It also depends on the drug's intended purpose; for example, if Albuterol is meant to help with breathing during physical activity or exercise, it can be used 15 to 30 minutes beforehand. If someone uses it to relieve symptoms of a lung disease, they might take it every four to six hours. This frequency may vary from one person to another.

  • Does Albuterol help with congestion?

    No, Albuterol is not meant to help with congestion. Albuterol is a bronchodilator that is used as a treatment for people diagnosed with asthma or COPD. It can help prevent and relieve wheezing, chest tightness, coughing, and trouble breathing.
