Hello XXXXXXX

Thanks for your query.

1. Levocetirizine dihydrochloride is an active principle of cetirizine, which is more effective & has less side effects than cetirizine.
Montelukast preparations, is used as a maintenance therapy to relieve symptoms of seasonal allergies.
I think that you may consult your physician about taking cetrizine instead.

2. In your post you have mentioned your location as Bangalore.
Climate-wise Bangalore is a very nice place.
However, one thing you need to be concerned about is the traffic & pollution in certain areas of the city.
A face mask should be used while traveling through those areas as well as when exposed to bed dust.
Alternatively you can take tablet Allegra (Fexofenadine) 60 mg twice a day, under the guidance of your Doctor.

3. Sputum can be thinned out by maintaining adequate hydration & avoiding cold food and drinks.
Steam inhalation therapy will also be helpful.

4. The reasons of not getting enough Oxygen (difficulty in breathing) is due to the hyper responsiveness of your respiratory mucosa to the allergens like dust.
Saturation levels of 99% indicate that your Hemoglobin is saturated with oxygen.
So, the main problem lies in the region of intake, that is, respiratory tract.

5. The individuals with GERD often present with respiratory symptoms.
This is attributed to the refluxed acid entering the respiratory tract & irritation of the respiratory mucosa.
And as you are taking medications for GERD, the risk factor is decreased.

Hope I have been able to answer your questions.
Kindly let me know if you have any further queries.
Take care.
