Refer to the Full Prescribing Information of co-administered palbociclib, abemaciclib, or ribociclib, for dose modification guidelines in the event of toxicities, for use with concomitant medications, and other relevant safety information.
2.3 Administration Technique
Administer the injection according to the local guidelines for performing large volume intramuscular injections.
NOTE: Due to the proximity of the underlying sciatic nerve, caution should be taken if administering Fulvestrant Injection at the dorsogluteal injection site [see Warnings and Precautions (5.3) and Adverse Reactions (6.1)].
The proper method of administration of Fulvestrant Injection for intramuscular use is described in the following instructions.
For each single-dose prefilled syringe:
- Remove glass syringe barrel from tray and check that it is not damaged.
- Inspect drug product in glass syringe for any visible particulate matter or discoloration prior to use. Discard if particulate matter or discoloration is present.
- Peel open the safety needle (SafetyGlideTM) outer packaging.
Hold the syringe upright. Twist and remove the Luer tip cap (see Figure 1).
- Do Not Touch the Sterile Syringe Tip (Luer-Lok).
Attach the safety needle to the syringe tip (Luer-Lok). Twist needle until firmly seated (see Figure 2). Confirm that the needle is locked to the Luer connector before moving or tilting the syringe out of the vertical plane to avoid spillage of syringe contents.
- Pull needle cap straight off needle to avoid damaging needle point.
- Expel excess gas from the syringe (a small gas bubble may remain).
Administer intramuscularly slowly (1-2 minutes/injection) into the buttock (gluteal area). For user convenience, the needle ‘bevel up’ position is orientated to the lever arm, as shown in Figure 3.
After injection, immediately activate the lever arm to deploy the safety shield by applying a single finger stroke to the activation assisted lever arm to push the lever arm completely forward. Listen for a click. Confirm that the safety shield has completely covered the needle (see Figure 4). NOTE: Activate away from self and others.
- Discard the empty syringe into an approved sharps collector in accordance with applicable regulations and institutional policy.
- Repeat steps 1 through 11 for second syringe.
How To Use Fulvestrant Injection
For the 2 x 5 mL syringe package, the contents of both syringes must be injected to receive the 500 mg recommended dose.
