From the Guidelines

Developing asthma after COVID-19 infection requires immediate medical attention to prevent long-term lung damage and improve quality of life. COVID-19 infection can potentially trigger asthma symptoms or worsen pre-existing asthma in some individuals, as it can damage airways and trigger inflammatory responses that lead to airway hyperreactivity and asthma symptoms 1. If you've developed asthma-like symptoms after COVID-19, consult a healthcare provider for proper diagnosis and treatment. Treatment typically includes rescue inhalers like albuterol (2 puffs every 4-6 hours as needed) for immediate symptom relief and possibly controller medications such as inhaled corticosteroids (like fluticasone or budesonide, typically used daily) to manage inflammation 1.

Key Considerations

  • Identifying and avoiding triggers like allergens, irritants, and respiratory infections is crucial for management.
  • COVID-19 can cause damage to the respiratory muscles, leading to persistent dyspnea and other functional limitations 1.
  • Regular follow-up appointments are important to adjust your treatment plan as needed, especially as your lungs recover from COVID-19 infection.
  • Pulmonary function tests may be recommended to monitor your lung function over time.

Treatment Approach

  • Controller medications such as inhaled corticosteroids should be used daily to manage inflammation and prevent asthma exacerbations.
  • Combination inhalers containing both a corticosteroid and a long-acting bronchodilator may be prescribed for moderate to severe cases.
  • Respiratory muscle testing and training may be beneficial in improving dyspnea and other key functional outcomes in patients with COVID-19 1.

From the Research

Developing Asthma after Covid Infection

  • There is limited research directly addressing the development of asthma after Covid infection.
  • However, studies have investigated the relationship between Covid-19 and asthma, including the risk of severe disease and the use of corticosteroids in treatment 2, 3, 4.
  • One study found that asthma diagnosis may be a risk factor for severe Covid-19, especially for those with severe disease or nonallergic phenotypes 4.
  • Another study suggested that Covid-19 does not appear to provoke asthma exacerbations, and asthma therapeutics should be continued for patients with exposure to Covid-19 4.
  • Research on inhaled corticosteroids for the treatment of Covid-19 found that they may reduce admission to hospital or death and increase resolution of all initial symptoms at day 14 5.
  • The current literature on asthma and Covid-19 is rapidly evolving, and clinicians must make case-by-case decisions to implement or continue current asthma therapy 6.
  • Overall, while there is no direct evidence on developing asthma after Covid infection, the existing research provides insights into the complex relationship between asthma and Covid-19 2, 3, 4, 5, 6.
