Recommended Vaccination and Prophylaxis

Vaccinate patients against encapsulated bacteria, including Streptococcus pneumoniae and Neisseria meningitidis (serogroups A, C, W, Y and B), according to current ACIP recommendations at least 2 weeks prior to initiation of EMPAVELI therapy [see Warnings and Precautions (5.1)].

If urgent EMPAVELI therapy is indicated in a patient who is not up to date with vaccines for Streptococcus pneumoniae and Neisseria meningitidis, according to ACIP recommendations, provide the patient with antibacterial drug prophylaxis and administer these vaccines as soon as possible.

Healthcare professionals who prescribe EMPAVELI must enroll in the REMS for EMPAVELI [see Warnings and Precautions (5.2)].

Recommended Dosage Regimen

The recommended dose of EMPAVELI is 1,080 mg administered subcutaneously twice weekly. EMPAVELI can be administered via a commercially available infusion pump with a reservoir of at least 20 mL or with EMPAVELI Injector.

Dosage for patients switching to EMPAVELI from C5 inhibitors

To reduce the risk of hemolysis with abrupt treatment discontinuation:

  • For patients switching from eculizumab, initiate EMPAVELI while continuing eculizumab at its current dose. After 4 weeks, discontinue eculizumab before continuing on monotherapy with EMPAVELI.
  • For patients switching from ravulizumab, initiate EMPAVELI no more than 4 weeks after the last dose of ravulizumab.

Dose Adjustment

  • For lactate dehydrogenase (LDH) levels greater than 2 × the upper limit of normal (ULN), adjust the dosing regimen to 1,080 mg every three days.
  • In the event of a dose increase, monitor LDH twice weekly for at least 4 weeks.

Missed Dose

  • Administer EMPAVELI as soon as possible after a missed dose. Resume the regular dosing schedule following administration of the missed dose.


EMPAVELI is for subcutaneous administration using:

  • an infusion pump OR
  • EMPAVELI Injector, a single-use, disposable on body injector

EMPAVELI is intended for use under the guidance of a healthcare professional. Train patients and/or caregivers on how to prepare and administer EMPAVELI prior to use. After proper training a patient may self-administer, or the patient's caregiver may administer EMPAVELI, if a healthcare provider determines that it is appropriate.

Follow the steps below and use aseptic technique to prepare and administer EMPAVELI, either by an infusion pump or EMPAVELI Injector:

  • Prior to use‚ allow EMPAVELI to reach room temperature for approximately 30 minutes. Keep the vial in the carton until ready for use to protect from light.
  • Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. EMPAVELI is a clear, colorless to slightly yellowish solution. Do not use if the liquid looks cloudy, contains particles, or is dark yellow.
  • Discard any unused portion of EMPAVELI.

Preparation with Infusion Pump

  • Refer to the EMPAVELI Instructions for Use and the infusion pump manufacturer's instructions for full preparation and administration information.
  • Use a needleless transfer device (such as a vial adapter) or a transfer needle to fill the syringe.
  • Rotate infusion sites (i.e., abdomen, thighs, hips, upper arms) from one infusion to the next. Do not infuse where the skin is tender, bruised, red, or hard. Avoid infusing into tattoos, scars, or stretch marks.
  • If multi-infusion sets are needed, ensure the infusion sites are at least 3 inches apart.
  • The typical infusion time is approximately 30 minutes (if using two infusion sites) or approximately 60 minutes (if using one infusion site).

Preparation with EMPAVELI Injector

  • Refer to the EMPAVELI Injector Instructions for Use, which comes with the device.
  • Use a needleless transfer device (such as a vial adapter).
  • EMPAVELI Injector is for abdominal subcutaneous use only. Rotate the site of each subcutaneous administration. Do not inject where the skin is tender, bruised, red, or hard. Avoid injecting into tattoos, scars, or stretch marks.
  • Injection time is approximately 30 to 60 minutes.
