If on antibiotics less than 30 days, individual can enroll after they have stopped their current antibiotic for 72 hours. Individuals on biologics can be enrolled if they have been on a stable dose for > 6 months and meet the ACT or exacerbation criteria as well as all other criteria after being on the stable does of the biologic.
• Specified medications for which close monitoring has been recommended in the setting of macrolide administration (digoxin, warfarin, theophylline, ergotamine or dihydroergotamine, cyclosporine, hexobarbital, phenytoin or nelfinavir).

• On a medication with known risk (i.e., that is associated with prolonged QT and associated with torsades de pointes even when taken as recommended)- absolute contraindication to eligibility- Full lists in Appendix B;

Egyéb

• Another family member living in the same household already enrolled in study;
• Life expectancy <1 year (operationalized by the question to the patient's asthma care clinician "Would you be surprised if this person died in the next 12 months? If yes - include, if no - exclude);
