DOSAGE AND ADMINISTRATION

Dosing Information

TRELSTAR must be administered under the supervision of a physician.

TRELSTAR is administered by a single intramuscular injection in either buttock. Dosing schedule depends on the product strength selected (Table 1). The lyophilized microgranules are to be reconstituted in sterile water. No other diluent should be used.

Due to different release characteristics, the dosage strengths are not additive and must be selected based upon the desired dosing schedule.

The suspension should be administered immediately after reconstitution.

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

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
