If your doctor just prescribed Fasenra (pronounced fah-SEN-rah; generic name benralizumab), you've probably already done a few things: googled the name, seen a price tag with a lot of zeros, and maybe felt a little overwhelmed. That's normal. Here's what's actually involved in starting Fasenra - and what changes when a specialty pharmacy handles the details for you.
Fasenra is a biologic that blocks a receptor for interleukin-5 (IL-5), a protein that drives certain white blood cells (eosinophils) linked to airway inflammation. It's approved as an add-on treatment for severe eosinophilic asthma in patients 12 and older, and for eosinophilic granulomatosis with polyangiitis (EGPA), a rare inflammatory blood vessel condition.
Fasenra is a subcutaneous injection, available as a prefilled syringe or the Fasenra Pen - an autoinjector that may allow self-administration after training, though many patients also receive it from a healthcare provider in-office. Ask your doctor which approach fits your situation. Typical starting dosing is monthly for the first three doses, then less frequently for maintenance - always follow your doctor's specific schedule.
Fasenra is prescribed on the basis of test results, which your prescriber confirms before the first dose is scheduled.
The list price for Fasenra is real, and it's startling - commonly cited between $5,200 and $6,440 per dose. But almost nobody pays that number. With commercial insurance and the Fasenra Savings Program from AstraZeneca, eligible patients can pay as little as $0 per injection, with up to $13,000-$14,000 in annual savings, for up to 24 months. If you're on Medicare or uninsured, the AZ&Me Prescription Savings Program may be able to help based on income.
The catch is that getting to that lower number involves paperwork: prior authorization, savings program enrollment, and sometimes an appeal if your insurance initially denies coverage. This is the single biggest thing a specialty pharmacy does that a regular retail pharmacy doesn't.
