Dose Adjustments

Dose adjustments:

• Dose adjustments are not appropriate during Initial dose escalation.
• Adjustments may be needed for allergic reactions, missed doses, or patient management needs during Up-dosing or Maintenance.
• Use dose adjustment to actively manage allergic reactions (including gastrointestinal) that are severe, recurrent, bothersome, or last longer than 90 minutes.
• Use clinical judgement when considering maintaining dose levels longer than 2 weeks, reducing or withholding doses, or discontinuation.

Consecutive Missed Doses:

• If one or two consecutive doses are missed, continue at same dose level.
• There is insufficient data on resumption of a dose level after 3 or more missed doses.

Discontinue for:

• Patients unable to tolerate up to 3 mg dose during Initial Dose Escalation
• Suspected eosinophilic esophagitis
• Inability to comply with daily dosing requirements
• Recurrent asthma exacerbations or persistent loss of asthma control
