Omalizumab adherence in an observational study of patients with moderate to severe allergic asthma

Adherence to omalizumab is characterized by distinct factors. Patients receiving the 4-week dosing regimen achieved better adherence than those treated every 2 weeks. Improved adherence could be associated with better asthma control. Age and lung function could interact with dosing frequency to affect patient adherence, thus warranting prospective planning at the time of prescribing to support long-term adherence.
