Selective Janus-kinase inhibitor

Abrocitinib (أبروسيتينيب)

Abrocitinib suppresses part of the immune system to treat moderate-to-severe atopic dermatitis when topical treatment is unsuitable or insufficient. It can increase the risk of serious infection, blood clots, major heart problems and cancer, so an experienced doctor must start and monitor it.

This medicine is used under close medical supervision, usually by a specialist. Never start, stop or change it without your doctor.
