Question 2

I'm dealing with chronic urticaria and have tried different antihistamines like Cetirizine, Fexofenadine, Desloratadine, and Levocetirizine, but they all cause me severe heartburn and acid reflux. I noticed that when I take Monlevo, which combines Montelukast Sodium and Levocetirizine Hydrochloride, I don't experience these side effects. Why do you think that is? Is there something about this combination that prevents the usual issues? What should I consider or discuss with my doctor about this?

Accepted Answer

because its prevents allergic conditions

Question 3

I've been noticing that whenever I touch something colder than the usual temperature, I start to sneeze. It's also happening with the early morning breeze sometimes, giving me that sneezing sensation. Is this something I should be concerned about or is it just a common reaction?

Accepted Answer

Chronic cold and cough can be frustrating.

Considering your allergy-like symptoms, possible causes include:

- Allergies (dust, pollen, pet dander)
- Environmental factors (pollution, tobacco smoke)
- Sinusitis or respiratory infections

For relief, try:

- Antihistamines (e.g., cetirizine, loratadine)
- Decongestants (e.g., pseudoephedrine)
- Nasal sprays (e.g., saline, oxymetazoline)
- Drinking plenty of fluids
- Using a humidifier

Consult a doctor or allergist to determine the underlying cause and receive personalized guidance.
