I'm dealing with a lung infection because of the climate here in Delhi. My doctor suggested taking TelekastL and Sereflo. I'm just a bit concerned about using TelekastL for a long period. Is it really safe? And should I be reconsidering living in Delhi if this is causing health issues? I'd really appreciate some insight into this.

Telekast-L (montelukast and levocetirizine) is generally safe for long-term use under medical supervision, but it may not address the root cause of a recurring lung infection. If Delhi's air quality consistently worsens your health, it may be worth considering relocating to a cleaner environment for long-term well-being.
