My 15 year old daughter has asthma that i have trouble controlling it. any suggestions?

15yo should B respon: Asthma control can be an issue of medications, events or compliance.Teens often have more compliance problems out of a sense of "why me" or presumed invulnerability.By 15 responsibility for maintaining control should be theirs.They need to figure out a good daily routine that incorporates preventive and rescue meds & be willing to stick with it or ask their doc to fine tune the process.

Add maintenance meds: If your daughter is only on a rescue inhaler (e.g. Albuterol) then add inhaled corticosteroid to treat inflammation; if on inhaled corticosteroid, add long acting beta agonist (laba) to relax bronchial muscles and open airways; if on inhaled corticosteroid and laba, increase dose of corticosteroid. You should be working closely with an md skilled in asthma management.

Control: I agree with dr. Ferguson that the teens are often a difficult time..Your doctor can help give your teen more control, and better control, by discussing and giving you both an asthma action plan, with a peak flow meter to get more objective data on how their asthma is doing. I would not rely on air purifiers etc although environmental control can sometimes help. ?Any smoking around them?
