* Reconstitute and administer the lyophilized microspheres as a single intramuscular injection.
  * The suspension should be administered immediately after reconstitution.
  * As with other drugs administered by intramuscular injection, the injection site should be alternated periodically.
  * Visually inspect LEUPROLIDE ACETATE FOR DEPOT SUSPENSION powder (white to off-white powder). DO NOT USE the vial if clumping or caking is evident. A thin layer of powder on the wall of the vial is considered normal prior to mixing with the diluent. The diluent contained in the prefilled syringe should appear clear and colorless.
  * Use ONLY the provided diluent for reconstitution of LEUPROLIDE ACETATE FOR DEPOT SUSPENSION. DO NOT use other diluents.
  * The reconstituted product is a suspension of milky, white color appearance.



LEUPROLIDE ACETATE FOR DEPOT SUSPENSION is packaged in a commercial kit. Each kit contains:

  * One vial containing 22.5 mg of leuprolide acetate as lyophilized microspheres.
  * One prefilled syringe containing 2 mL of mannitol for injection.
  * One MIXJECT transfer device including one needle. 



Please read the instructions completely before you begin.

MIXJECT Preparation

Wash your hands with soap and hot water and put on gloves1 immediately prior to preparing the injection. Place the tray on a clean, flat surface that is covered with a sterile pad or cloth. Remove the MIXJECT device, the backstop, the prefilled syringe containing the solvent for reconstitution and the LEUPROLIDE ACETATE FOR DEPOT SUSPENSION vial.

Remove the Flip-Off button from the top of the vial, revealing the rubber stopper. Place the vial in a standing upright position on the prepared surface. Disinfect the rubber stopper with the alcohol wipe. Discard the alcohol wipe and allow the stopper to dry. Insert the backstop to the flange of the syringe until you feel it snap in place. Proceed to MIXJECT Activation.

MIXJECT Activation

  1. Peel the cover away from the blister pack containing the vial adapter (MIXJECT). Do not remove the vial adapter from the blister pack. Place the blister pack containing the vial adapter firmly on the vial top, piercing the vial. Push down gently until you feel it snap in place.
  2. Remove the cap from the syringe barrel and then, remove the blister pack from the vial adapter. Connect the syringe to the vial adapter by screwing it clockwise into the opening on the side of the vial adapter. Be sure to gently twist the syringe until it stops turning to ensure a tight connection.  

  3. While holding the vial, place your thumb on the plunger rod and push the plunger rod in all the way to transfer the diluent from the pre-filled syringe into the vial. Do not release the plunger rod.  

  4. Keeping the plunger rod depressed, gently swirl the vial for approximately one minute until a uniform milky-white suspension is obtained. This will ensure complete mixing of LEUPROLIDE ACETATE FOR DEPOT SUSPENSION and the sterile mannitol solution diluent. The suspension will now have a milky appearance. In order to avoid separation of the suspension, proceed to the next steps without delay.  

  5. Invert the MIXJECT system so that the vial is at the top. Grasp the MIXJECT system firmly by the syringe and pull back the plunger rod slowly to draw the reconstituted LEUPROLIDE ACETATE FOR DEPOT SUSPENSION into the syringe.  
Grasp only the plastic cap when removing.  

  6. Keep the syringe UPRIGHT. With the opposite hand pull the needle cap upward. Advance the plunger to expel the air from the syringe. The syringe containing LEUPROLIDE ACETATE FOR DEPOT SUSPENSION is now ready for administration. The suspension should be administered immediately after reconstitution.   

  7. After cleaning the injection site with an alcohol swab, administer the intramuscular injection by inserting the needle at a 90 degree angle into the gluteal area, anterior thigh, or deltoid; injection sites should be alternated (see Figure).  

  8. Inject the entire contents of the syringe intramuscularly.
  9. Withdraw the needle. Once the syringe has been withdrawn, immediately discard the needle into a suitable sharps container. Dispose the syringe according to local regulations/procedures.
