After taking Mengluste it is best to take the New Crown vaccine after the asthma symptoms are relieved and when the condition is stable, depending on the condition of the disease, and the New Museum vaccine should not be injected during the disease flare-up period. Montelukast is mainly a drug for the treatment of bronchial asthma and bronchial inflammation. If there is a recent acute attack of asthma and the symptoms are not controlled such patients are not suitable for the New Crown vaccine. If you have been taking Menlustat orally for a long time for asthma, but your asthma has been very stable, for example, for more than six months, you can get the new crown vaccine. If you are taking montelukast only to treat acute respiratory inflammation, you can go for the new crown vaccine after your symptoms have subsided for more than a week after stopping the montelukast. If this type of patient needs to have the New Crown vaccine, it is recommended to consult with the vaccination center.
