Patient Li**678 asked: Hello, Dr. Wen! I am your patient, I am allergic to dust mite and cypress, which caused cough variant asthma, now it seems that my asthma is coming back, sometimes I cough, can I get the AFL vaccine? When is the right time to do it? Dr. Wen’s answer: It is recommended to wait until your cold symptoms disappear for a while. My personal advice is: interval of about one week before and after the influenza A vaccine and allergen desensitization treatment, and avoid the injection on the same side of the arm! Patient Li**678 asked: Hello Dr. Wen! Thank you for your last answer, I still have a question for you. I seem to have a relapse of asthma, which is characterized by coughing at night and occasional coughing during the day, I started inhaling hormones again, and now I am better, but I still have some coughing at night or in the morning. Can I continue to take desensitization injections in this case? Should I still start from 0.1 of 3? Answer from Dr. Wen: The cough at night and in the morning should be taken seriously, because this is the low point of lung function, and the cough at this time indicates that your asthma or bronchial inflammation is not satisfactorily controlled! It is recommended to increase the dose of inhaled hormone appropriately, and you can use the combination of inhaled hormone + long-acting beta2 agonist for a period of time. Of course, considering the possible side effects of inhaled hormone, please make sure to rinse your mouth and throat carefully after inhalation! Wait until the symptoms are completely controlled before reducing the dose. About the relationship between asthma control and desensitization treatment: In the case that asthma can be well controlled, the injection can be continued as long as there is no uncomfortable reaction locally or systemically. If there are any questions, it is recommended to consult the doctor who took the medication in person. Patient Li**678 asked: I have another question for you, many Chinese medicines are written for allergy sufferers. Am I allergic to them? Is it because of the cough and asthma flare-ups caused by those pCms? Answer from Dr. Wen: Actually, a person with allergies is not necessarily allergic to everything. Dust mite and cypress allergies do not necessarily mean that Chinese medicines are allergic, and almost all medicines will state in the instruction manual that “use with caution or forbid if allergic to this product”. It is true that proprietary Chinese medicines can cause allergies and even liver and kidney dysfunction. Therefore, it is recommended to apply them under the guidance of a doctor and to observe them by yourself. Lastly, I would like to remind you that you cannot see the patient face-to-face to fully understand the condition, so the above suggestions are for reference only, please go to the hospital for specific treatment under the guidance of a doctor!
