Treatment Options for Respiratory Syncytial Virus (RSV) in Infants
Respiratory Syncytial Virus (RSV) is a common respiratory virus that can cause cold-like symptoms and infections in the lungs and respiratory tract. For many people, RSV infection causes a mild illness. Infants are at higher risk of developing more severe RSV illness that may require hospitalization.
The objective of treatment for RSV in infants is to control symptoms and prevent complications. Treatment for RSV is primarily supportive, meaning it focuses on relieving symptoms and providing comfort while the body fights off the infection.
It's important to note that specific antiviral medications may be used in certain cases of severe RSV infection. However, these medications are not curative but rather aim to slow down the progression of the illness and reduce the severity of symptoms.
The initial recommended treatment for RSV in infants is supportive care. Supportive care measures may include:
- Ensuring proper hydration by encouraging fluids intake
- Using saline nasal drops or sprays to relieve nasal congestion
- Providing fever-reducing medications such as acetaminophen or ibuprofen, if necessary, under the guidance of a healthcare professional.
- Using a cool-mist humidifier in the room to help ease breathing and reduce congestion.
- Keeping the baby's environment clean and free from irritants, such as tobacco smoke.
- Monitoring the baby's breathing and seeking medical attention if there are signs of respiratory distress or worsening symptoms.
In some cases, doctors may prescribe medications to manage certain symptoms or complications associated with RSV infection. These may include:
- Bronchodilators: These medications can help relax the muscles around the airways and improve breathing in infants with wheezing or respiratory distress.
- Corticosteroids: In some cases, corticosteroids may be prescribed to reduce airway inflammation and improve respiratory symptoms.
- Antiviral medication: Ribavirin is an antiviral drug that works by inhibiting the replication of the virus. Inhaled ribavirin is the only FDA-approved medication for RSV. It is used to treat hospitalized infants and young children with severe lower respiratory tract infections due to RSV.

While not a treatment for active RSV infection, preventive strategies can help reduce the risk of severe RSV illness in infants. These strategies include:
- Good hand hygiene: Regularly washing hands with soap and water or using alcohol-based hand sanitizers can help prevent the spread of RSV.
- Avoiding close contact with sick individuals: Infants should be kept away from people who have respiratory infections, especially if they have symptoms like coughing or sneezing.
- Immunization: There is currently no approved RSV vaccine for infants. However, two preventive strategies to protect a newborn against RSV are:
- Maternal RSV vaccine: The Centers for Disease Control and Prevention (CDC) recommends Abrysvo, the only FDA-approved maternal RSV vaccine, for people who 32 to 36 weeks pregnant. This helps the mother pass RSV antibodies to the baby to provide protection against RSV after the baby is born.
- RSV monoclonal antibody: Newborns whose mothers did not receive maternal RSV vaccine during the pregnancy may receive a nirsevimab shot to provide RSV antibodies to protect against RSV infection. Nirsevimab may also be used in young children (8-19 months) who are at high risk of severe RSV infection.
It's important to note that treatments are still being studied and evaluated for their effectiveness in treating RSV in infants. Always consult with your child's healthcare provider before considering any specific treatment options.
