INVEGA SUSTENNA® 2nd Initiation Dose: <4 weeks since 1st injection
Consistent with the INVEGA SUSTENNA® Prescribing Information:
- If the target date for the second INVEGA SUSTENNA® injection (one week ± 4 days) is missed, the recommended reinitiation depends on the length of time which has elapsed since the patient's first injection.
- It is recommended to administer a third injection of 117 mg in either the deltoid or gluteal muscle 5 weeks after the first injection (regardless of the timing of the second injection).
- Thereafter, resume regular monthly dosing in either the deltoid or gluteal muscle.
- Administration: Each injection must be administered only by a healthcare professional. INVEGA SUSTENNA® is intended for intramuscular use only. Do not administer by any other route. Avoid inadvertent injection into a blood vessel.
