Generic name: triptorelin pamoate
Dosage form: injectable suspension

TRELSTAR LA Must Be Administered Under the Supervision of a Physician.

The recommended dose of TRELSTAR LA is 11.25 mg incorporated in a long acting formulation administered every 84 days as a single intramuscular injection administered in either buttock. The lyophilized microgranules are to be reconstituted in sterile water. No other diluent should be used. Reconstitute in accord with the following:


  1. Using a syringe fitted with a sterile 20-gauge needle, withdraw 2 mL sterile water for injection, USP, and after removing the flip-off seal from the vial, inject into the vial.

  2. Shake well to thoroughly disperse particles to obtain a uniform suspension. The suspension will appear milky.

  3. Slowly withdraw the entire contents of the reconstituted suspension into the syringe.

  4. Inject the patient in either buttock with the contents of the syringe.

For the TRELSTAR LA Clip'n'Ject® single-dose delivery system, see adjacent INSTRUCTIONS FOR CLIP'N'JECT® USE section.

The suspension should be discarded if not used immediately after reconstitution.

As with other drugs administered by intramuscular injection, the injection site should be altered periodically.
