General Administration Instructions

FASENRA is for subcutaneous use only.

FASENRA is intended for use under the guidance of a healthcare provider. In line with clinical practice, monitoring of patients after administration of biologic agents is recommended.

Administer FASENRA into the thigh or abdomen. The upper arm can also be used if a healthcare provider or caregiver administers the injection. Prior to administration, warm FASENRA by leaving carton at room temperature for about 30 minutes. Visually inspect FASENRA for particulate matter and discoloration prior to administration. FASENRA is clear to opalescent, colorless to slightly yellow, and may contain a few translucent or white to off-white particles. Do not use FASENRA if the liquid is cloudy, discolored, or if it contains large particles or foreign particulate matter.

Prefilled Syringe

The prefilled syringe is for administration by a healthcare provider.

Autoinjector (FASENRA PEN™)

FASENRA PEN is intended for administration by patients/caregivers. Patients/caregivers may inject after proper training in subcutaneous injection technique, and after the healthcare provider determines it is appropriate.

In asthma patients aged 6 to 11 years weighing 35 kg or more, FASENRA PEN should only be administered by a caregiver or healthcare provider.

Prefilled Syringe Components

To prepare FASENRA prefilled syringe for subcutaneous administration, carefully read and adhere to these instructions for use. FASENRA is available in a 10 mg and a 30 mg prefilled syringe. Check the labels on the FASENRA carton and prefilled syringe to ensure the correct 10 mg or 30 mg product is being used (Figure 1). Refer to Figure 1 to identify the prefilled syringe components for use in the administration steps.

Do not touch the needle guard activation clips to prevent premature activation of the needle safety guard.

1	Grasp the syringe body, not the plunger, to remove prefilled syringe from the tray. Check the expiration date on the syringe. The syringe may contain small air bubbles; this is normal. Do not expel the air bubbles prior to administration.
2		Do not remove needle cover until ready to inject. Hold the syringe body and remove the needle cover by pulling straight off. Do not hold the plunger or plunger head while removing the needle cover or the plunger may move. If the prefilled syringe is damaged or contaminated (for example, dropped without needle cover in place), discard and use a new prefilled syringe.
3		Gently pinch the skin and insert the needle at the recommended injection site (i.e., upper arm, thigh, or abdomen).
4		Inject all of the medication by pushing in the plunger all the way until the plunger head is completely between the needle guard activation clips. This is necessary to activate the needle guard.
5		After injection, maintain pressure on the plunger head and remove the needle from the skin. Release pressure on the plunger head to allow the needle guard to cover the needle. Do not re-cap the prefilled syringe.
6	Discard the used syringe into a sharps container.

Refer to the FASENRA PEN ‘Instructions for Use’ for more detailed instructions on the preparation and administration of FASENRA PEN.

In patients aged 6 to 11 years weighing 35 kg or more, FASENRA PEN should only be administered by a caregiver or healthcare provider.
