Is it okay for a 17-year-old boy to use an asthalin inhaler? If I start using it, do I need to carry it everywhere I go? Could it actually lead to more breathing issues after using it? I checked online and found info saying the inhaler works for about 4-6 hours after taking two puffs. Does that mean the breathing problems will definitely return after those hours?

consult pulmonologist he will guide you about good inhalers that u have to take for only one or two times according to your requirements
