My 12 year old son has exercise induced asthma.  He just finished cross country running season and would take one puff of an inhaler before running a 2 mile race (about a 6 minute mile +/-).  It worked wonders.  Now he is starting basketball tryouts and the practices are 2 hours long (for tryouts) with a ton of sprinting.  Is it safe for him to use the inhaler once before practice and once half way through?
Namaste Welcome to Chat Doctor Greetings of the day Its totally safe to take.  Apart from it steam inhalation before sleeping and after Getting up will also be helpful. Take care Regards
