Andembry has no safety program forms, no required blood tests and no dose build-up beyond a first-day loading dose. The first injections wait on a referral form, an insurance approval, a pharmacy delivery and injection training. After that the routine is one refrigerated autoinjector a month. This page lays out those weeks from the FDA label, CSL Behring's own Andembry pages and one insurer's written rules.

What has to happen before the first bottle ships

Andembry has no REMS, so the first dose waits on the referral form, a prior authorization, a pharmacy delivery and injection training. These are the 6 things in the way, in order.

The referral form

CSL Behring's prescriber site asks the office to complete a referral form and send it to ANDEMBRY Connect.

  • The office can use the electronic form or fax it.
  • ANDEMBRY Connect confirms receipt and may ask for more documents the insurer requests.HCP enrollment page

Three calls to answer

CSL Behring asks you to answer 3 calls.

  • ANDEMBRY Connect calls from 1-844-423-4273, and the specialty pharmacy calls from 1-855-393-3656 to schedule the shipment.
  • A training nurse calls from 1-941-556-8515 if you choose nurse training.ANDEMBRY Connect

The insurance approval

Plans such as Cigna require prior authorization.

  • Cigna asks for lab results showing HAE type I or type II and an allergist, immunologist or HAE specialist.Cigna policy

A QuickStart supply at no cost

ANDEMBRY Connect says the QuickStart Program ships a 1-month supply at no cost.

  • Eligible patients can continue and receive up to 2 months.
  • CSL Behring says the supply may be extended during the insurance approval process.ANDEMBRY Connect

  1. Referral form, then the insurance check

    The office sends the referral form to ANDEMBRY Connect online or by fax.

    • ANDEMBRY Connect confirms receipt and may ask the office for documents the insurer requests.
    • No source sets how long approval takes.
  2. Three calls

    Your case manager helps coordinate the QuickStart request, and the specialty pharmacy calls to schedule the shipment.

    • A nurse calls too if you choose nurse training.
  3. Delivery and injection training

    The autoinjectors go into the refrigerator in their original cartons.

    • The label says a healthcare provider should train you or your caregiver before the first injection.

    • The instructions say to take each autoinjector out of the refrigerator 30 minutes before use.
  5. Refills, one carton a month

    Each carton holds one single-dose autoinjector, so each monthly dose is one carton.

    • The label does not set how many cartons a pharmacy ships at once.
  6. First monthly dose, then every month

    The maintenance dose is 200mg, one autoinjector, once a month.

    • On a monthly schedule, the next doses fall around days 61 and 91.
  7. Refills, number 2

  8. First monthly dose, number 2

  9. Refills, number 3

  10. Three months in

    • It is not known whether it passes into breast milk.FDA label

What the label says to act on

The symptoms the label singles out, and what it tells patients and prescribers to do about each. If any of these happen, the label's instruction is the one to follow, with your care team.

A dose that may not have gone in

The instructions say to contact your healthcare provider right away if you think you did not get the full dose.

  • A full dose means the yellow plunger filled the window and stopped moving.FDA label

  • The allergist decides what they mean for the plan.FDA label

What CSL Behring says about rescue medicine

CSL Behring's Andembry patient site says attacks can still occur with all HAE medications.

Why the pharmacy or the insurer says no, and what fixes it

Most first-fill delays are one of these. Knowing which one tells you who to call.

  • Prior authorization pending or deniedCigna asks for a functional C1-INH level under 50% of normal and a low C4 level, each with lab documentation. It also wants an allergist, immunologist or HAE specialist, and a patient aged 12 or older.Cigna policy
  • Other medicines the plan wants tried firstFor employer plans, Cigna approves Andembry if the patient has tried both Haegarda and Takhzyro, or is already receiving Andembry. The policy lists this step in its table for employer plans.Cigna policy
  • HAE with normal C1-INHCigna's policy says HAE with normal C1-INH, also called type III, does not meet its diagnosis requirement. That holds for first approvals and for renewals.Cigna policy
  • Another preventive medicine at the same timeCigna lists Andembry used with other preventive HAE medicines, such as Cinryze, Haegarda, Orladeyo or Takhzyro, as not medically necessary. Medicines that treat an attack, or prevent one around a procedure, are allowed.Cigna policy
  • A dose the plan will not coverCigna approves a one-time 400mg loading dose, then 200mg no more often than once a month. Other doses go to case-by-case review by a Cigna clinician.Cigna policy
  • Paperwork the insurer asks forCSL Behring's checklist lists what major insurers most often ask for, including C4 and C1-INH lab results, attack history and earlier treatments. It says CSL Patient Services can help the office at 1-844-423-4273.CSL Behring PA checklist

What one insurer asks for, as an example

Cigna prior authorization policy, January 1, 2026

  1. Age 12 or older
  2. HAE type I or type II, with a functional C1-INH protein level under 50% of normal at baseline, with lab documentation
  3. A serum C4 level below normal at baseline, with lab documentation
  4. HAE with normal C1-INH, also called type III, does not meet the diagnosis requirement
  5. Prescribed by or in consultation with an allergist, immunologist or a physician who specializes in HAE
  6. For employer plans, a trial of both Haegarda and Takhzyro, unless the patient is already receiving Andembry
  7. A one-time 400mg loading dose, then 200mg no more often than once every month
  8. Not used together with another preventive HAE medicine such as Cinryze, Haegarda, Orladeyo or Takhzyro

Approval length. Approved a year at a time. Renewal asks for HAE type I or II and a favorable response, such as fewer, milder or shorter attacks.

This is a new policy that took effect January 1, 2026. It cites the June 2025 prescribing information, which is the current label. Its step through Haegarda and Takhzyro sits in the table for employer plans. Other plans set their own criteria. It is here as an example, not as a rule. Cigna policy

Five questions for the pharmacist or the support line

  1. How many autoinjectors come in the first shipment, since the first-day dose uses two?
  2. When will each monthly shipment arrive, and who do I call to schedule it?
  3. What do I do if a shipment arrives warm or frozen?
  4. Where can I get a sharps container for used autoinjectors?
  5. Which on-demand HAE medicine do I keep at home, and is that prescription current?

Questions people ask in the first weeks

How often is Andembry given?

Once a month, after a first-day loading dose. The label dose is 400mg on the first day, given as two 200mg injections, then 200mg once a month. The dose is the same for adults and children 12 and older.

Can I give Andembry myself?

Yes, the label says Andembry is meant for self-injection or injection by a caregiver, after training by a healthcare provider. The instructions say children should inject under the supervision of an adult. ANDEMBRY Connect offers injection training through its nursing team.

Does Andembry treat an HAE attack?

No, the label approves it only to prevent attacks. In the main trial, everyone could use on-demand medicine to treat attacks. The allergist or immunologist decides which on-demand medicine you keep on hand.

Do I need blood tests on Andembry?

No, the label sets no routine blood tests. Andembry can lengthen the aPTT clotting test because of how the test works. In the main trial, none of the longer clotting times came with bleeding.

How do I store Andembry?

In the refrigerator at 36°F to 46°F (2°C to 8°C), in the original carton, never frozen or shaken. Take it out 30 minutes before the injection. The instructions say not to put it back in the refrigerator after it reaches room temperature.

What if I miss a dose of Andembry?

The label says to give a missed dose as soon as possible. It gives no further detail, so the prescriber decides how the doses after it are timed.

Is there help paying for Andembry?

ANDEMBRY Connect lists co-pay support for people with commercial insurance, subject to program terms. It says it shares resources that can help people with government insurance. Its QuickStart Program ships a 1-month supply at no cost, with up to 2 months for eligible patients.
