How to effectively treat allergic cough symptoms?


Hello Doctor, I have had small red itchy rashes on my skin since childhood.
In recent years, I have started to experience phlegm in my throat, persistent coughing, and runny nose in the morning and evening.
Recently, the coughing has become severe, affecting my daily life, so I visited a family medicine clinic.
An X-ray showed that my lungs were filled with phlegm.
The family medicine doctor told me it was an allergy, and after taking medication for a week without improvement, I did not continue follow-up visits.
Later, I went to a dermatology clinic where the dermatologist prescribed medication that was effective; for the past two weeks, my coughing symptoms completely disappeared.
However, this week marks my third consecutive follow-up visit, and the coughing and rash symptoms have returned, which is really troubling.

I am considering allergy testing, but I have read online that many people say it is not useful, so I would like to ask if it is necessary to undergo allergy testing? Also, is allergy treatment solely about taking medication to relieve symptoms, or do I need to visit a major hospital to get more information? I suspect that my allergen might be caffeine, as I experience palpitations whenever I consume it, but since I rarely encounter it, I am unsure if it is related to my coughing and skin allergies.

Additionally, I had blood tests done at the dermatology clinic, and the report showed that my eosinophil count was 210/µL and my immunoglobulin E level was 96.3 IU/mL.
Both values appear to be within the normal range for adults, but I am still unable to control my coughing, which is quite distressing.
I have discarded the medication details from the family medicine clinic, but I remember that the dermatologist prescribed oral medications on three occasions: 1.
Prinate (1 dose), Tonfo (0.5 dose), Asumalife tab (0.5 dose), Cowemin (1 dose); 2.
Cetirizine (0.5 dose), Tonfo (0.5 dose), Asumalife tab (1 dose); 3.
Cetirizine (0.5 dose), Tonfo (0.5 dose), Asumalife tab (1 dose).
The contents of the third prescription bag included: SET Cetirizine (SET) oral, PDL2 Prednisolone (5 mg) oral, Tonfo (PDL2), ZADT Ketotifen (1 mg) oral, Kcfcn (ZADT).

I am unsure if the information I provided is useful and whether allergies can be completely cured.
Since it is inconvenient for me to visit a major hospital, I hope to consult with a doctor online first.
Thank you!

Hello, if there is significant improvement in symptoms with the use of antihistamines, it is indeed possible that the cough is allergy-related.
If symptoms continue to be poorly controlled, you may consider undergoing allergy testing to identify the allergens and reduce exposure, which can decrease the frequency of symptom flare-ups.
Caffeine-induced palpitations are related to the effects of caffeine rather than allergies.
If symptoms persist without improvement, it is advisable to continue follow-up visits or seek further evaluation at a hospital.
Wishing you safety and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Managing allergic cough symptoms can be quite challenging, especially when they interfere with daily life. Based on your description, it seems that you have been experiencing persistent cough, throat phlegm, and skin rashes, which have been diagnosed as allergic reactions. Here are some effective solutions and insights into managing your symptoms.


Understanding Allergic Cough
An allergic cough is often a response to allergens that irritate the respiratory system. Common triggers include pollen, dust mites, pet dander, mold, and certain foods. In your case, it seems that you might also have a sensitivity to caffeine, which can cause palpitations but is less commonly associated with respiratory symptoms.

Importance of Allergy Testing
You mentioned considering allergy testing but were unsure of its necessity. Allergy testing can be beneficial as it helps identify specific allergens that trigger your symptoms. Knowing your triggers allows you to avoid them, which can significantly reduce your symptoms. While some people report mixed results from allergy testing, it can still provide valuable insights and guide your treatment plan.


Treatment Options
1. Medications:
- Antihistamines: Medications like Cetirizine (which you have been taking) can help alleviate symptoms by blocking histamine, a substance your body releases during an allergic reaction.
- Corticosteroids: Prednisolone is a corticosteroid that can reduce inflammation in your airways. If your symptoms persist, you might need a longer course or a different formulation.

- Leukotriene Receptor Antagonists: These medications can also be effective in managing allergic symptoms and may be worth discussing with your doctor.

- Expectorants: If you have thick phlegm, expectorants can help thin it out, making it easier to cough up.

2. Avoidance of Triggers:
- Identify and avoid known allergens. This may involve lifestyle changes, such as using air purifiers, keeping windows closed during high pollen seasons, and regularly cleaning your living space to reduce dust and mold.

3. Lifestyle Modifications:
- Diet: If you suspect caffeine is a trigger, consider reducing or eliminating it from your diet.
- Hydration: Staying well-hydrated can help thin mucus and soothe your throat.

- Humidity Control: Using a humidifier can help keep your airways moist, which may alleviate coughing.

4. Consultation with Specialists:
- If your symptoms do not improve with the above measures, consider consulting an allergist or an immunologist. They can provide specialized testing and treatment options, including immunotherapy (allergy shots) if appropriate.

5. Regular Follow-ups:
- Since you have experienced fluctuations in your symptoms, regular follow-ups with your healthcare provider are essential. They can adjust your treatment plan based on your response to medications and any new symptoms that arise.


Conclusion
In summary, managing allergic cough symptoms involves a combination of identifying and avoiding triggers, using appropriate medications, and making lifestyle changes. Allergy testing can provide valuable information that can help tailor your treatment. If your symptoms persist despite these measures, seeking further evaluation from a specialist may be necessary. Remember, effective management of allergies often requires a multi-faceted approach, and ongoing communication with your healthcare provider is key to finding the right balance for your health.
