My Patients Ask — Should asthmatics on Singulair or Symbicort stop these meds before or after the COVID vaccine?

Symbicort is an inhaled combination of a corticosteroid and a bronchial dilator used for asthma and chronic obstructive pulmonary disease while Singulair is a leukotriene receptor antagonist that has anti-inflammatory properties and is used in asthma and allergy treatment.

The American Academy of Allergy, Asthma, and Immunology says, “There is no data to suggest that inhaled corticosteroids and/or leukotriene receptor antagonists impact on the immunogenicity of the mRNA COVID-19 vaccines.”

As to whether patients with asthma should stop either or both medications before or after the vaccine, the AAAAI says, “No!”

They add, “There is no impact on an individual’s ability to respond to the vaccine, and control of asthma is essential!”
