When to Start Your Renewal Process

Start 60-90 days before your current authorization expires. Humana typically approves Takhzyro for 12-month periods, but some patients receive shorter authorizations (6 months) if their case requires closer monitoring.

Renewal Triggers to Watch For:

  • Pharmacy notification: Your specialty pharmacy will typically contact you 30-45 days before expiration
  • Insurance card changes: New plan year (January 1st) often requires reauthorization even if your previous approval hasn't expired
  • Dosing changes: Moving from every-2-weeks to every-4-weeks dosing requires new documentation
  • Provider changes: New prescriber means starting the authorization process fresh
Tip: Set a calendar reminder 90 days before your authorization expires. Many patients discover expiration only when their pharmacy can't fill their next dose.

If Coverage Lapses: Bridge Options

If your Takhzyro authorization expires before renewal approval, discuss these temporary bridge therapies with your HAE specialist:

  • Have your emergency action plan readily available
Critical: Takhzyro is not approved for acute attack treatment. Never delay emergency care during a coverage gap.
