Some serious medicines called biologics help treat severe asthma, and many can be given by patients at home instead of going to a clinic.
A study looked at how well these home treatments work, finding that most patients (over 95%) were successful at giving themselves the medicine and preferred doing it at home.
Patients felt confident and found it easy to use the self-administration devices, which also helped their asthma control and health quality, although more research is needed.
