Handling and access
NIOSH hazardous drug
Table 2NIOSH lists leuprolide as a hazardous drug. AHFS class: 68:18.08 gonadotropins; 10:00 antineoplastic agents.
- Meets the NIOSH definition of a hazardous drug (carcinogenicity, developmental or reproductive toxicity, organ toxicity at low doses, or genotoxicity) without MSHI or a Group 1 or 2A carcinogen classification.
- Only a developmental and/or reproductive hazard: precautions matter most for workers who are pregnant, breastfeeding, or trying to conceive.
Handle with the precautions your facility uses for hazardous drugs (USP <800>). NIOSH's Managing Hazardous Drug Exposures lists controls by drug form and activity.

Enter a dose to see draw volume, final concentration, and rates.
Preparation Instructions Use aseptic technique throughout the procedure. As with other similar agents, the use of gloves is recommended during mixing and administration. Allow the product to reach room temperature before mixing. Once mixed, the product must be administered within 30 minutes or it should be discarded. VABRINTY is packaged in a carton containing: Tray containing pre-connected syringe system and desiccant pack Prescribing information Sterile safety needle and cap (located under the tray in carton) Follow the detailed instructions below to ensure correct preparation of VABRINTY prior to administration: [See table below.] Note: Should the needle hub appear to be damaged, or leak, the product should NOT be used.
The damaged safety needle and cap should NOT be replaced and the product should NOT be injected. In the event of damage to the needle hub, use a new replacement VABRINTY carton. mixing step2 step3 step4 step5 step6 step7
Administration Instructions 1. Select an injection site on the abdomen, upper buttocks, or another location with adequate amounts of subcutaneous tissue that does not have excessive pigment, nodules, lesions, or hair and hasn’t recently been used. 2. Cleanse the injection-site area with an alcohol swab (not enclosed). 3.
Using the thumb and forefinger, grab and bunch the area of skin around the injection site. 4. Using your dominant hand, insert the needle quickly at a 90° angle to the skin surface. The depth of penetration will depend on the amount and fullness of the subcutaneous tissue and the length of the needle. After the needle is inserted, release the skin. 5.
Inject the drug using a slow, steady push and press down on the plunger until the syringe is empty. Make sure all the drug has been injected before removing the needle. 6. Withdraw the needle quickly at the same 90° angle used for insertion. 7. Immediately following the withdrawal of the needle, activate the safety shield using a finger/thumb or flat surface and push until it completely covers the needle tip and locks into place. 8.
An audible and tactile “click” verifies a locked position. 9. Check to confirm the safety shield is fully engaged. Discard all components safely in an appropriate biohazard container. admin1 admin admin
Contraindications
Hypersensitivity VABRINTY is contraindicated in patients with hypersensitivity to GnRH, GnRH agonist analogs or any of the components of VABRINTY. Anaphylactic reactions to synthetic GnRH or GnRH agonist analogs have been reported in the literature. Known hypersensitivity to GnRH, GnRH agonist analogs or any of the components of VABRINTY ( 4 )
Safety data
Reported adverse events (FAERS)
Liver injury (LiverTox)
ELikelihood score E: Unlikely cause of clinically apparent liver injury.
Leuprolide is a parenterally administered, gonadotropin releasing hormone (GnRH) agonist which causes an inhibition of estrogen and androgen production and is used predominantly to treat advanced prostate cancer. Leuprolide has been associated with a modest rate of serum enzyme elevations during therapy, but has not been convincingly linked to instances of clinically apparent acute liver injury.
ABCDEA: well known cause; E: unlikely cause. [HD]: high doses only.
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Risk Summary Based on findings in animal studies and mechanism of action, VABRINTY may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology ( 12.1 )] . There are no available data in pregnant women to inform the drug-associated risk. Expected hormonal changes that occur with VABRINTY treatment increase the risk for pregnancy loss. In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation in rats. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus (see Data) .
Data Animal Data In animal developmental and reproductive studies, major fetal abnormalities were observed after administration of leuprolide acetate throughout gestation. There were increased fetal mortality and decreased fetal weights in rats and rabbits. The effects of fetal mortality are expected consequences of the alterations in hormonal levels brought about by this drug.
For breastfeeding, also see LactMed (National Library of Medicine), which summarizes milk levels and infant effects.
