Dosage/Direction for Use
For patients who have never taken oral paliperidone or oral or injectable risperidone, it is recommended to establish tolerability with oral paliperidone or oral risperidone prior to initiating treatment with INVEGA SUSTENNA.
Dosage: Schizophrenia: Recommended initiation of INVEGA SUSTENNA is with a dose of 150 mg on treatment day 1 and 100 mg one week later, both administered in the deltoid muscle. The recommended monthly maintenance dose is 75 mg; some patients may benefit from lower or higher doses within the recommended range of 25 to 150 mg based on individual patient tolerability and/or efficacy. Following the second initiation dose, monthly maintenance doses can be administered in either the deltoid or gluteal muscle.
Schizoaffective disorder: Recommended initiation of INVEGA SUSTENNA is with a dose of 150 mg on treatment day 1 and 100 mg one week later, noth administered in the deltoid muscle. The recommended monthly maintenance dose is within the range of 50 to 150 mg adjusted based on tolerability and/or efficacy using available strengths. The 25 mg strength was not studied in schizoaffective disorder. Following the second initiation dose, monthly maintenance doses can be administered in either the deltoid or gluteal muscle.
Adjustment of the maintenance dose may be made monthly. When making dose adjustments, the prolonged-release characteristics of INVEGA SUSTENNA should be considered (see Pharmacology: Pharmacokinetic under Actions), as the full effect of the dose adjustment may not be evident for several months.
Missed doses: Avoiding missed doses. It is recommended that the second initiation dose of INVEGA SUSTENNA be given one week after the first dose. To avoid a missed dose, patients may be given the second dose 2 days before or after the one-week timepoint. Similarly, the third and subsequent injections after the initiation regimen are recommended to be given monthly. To avoid a missed monthly dose, patients may be given the injection up to 7 days before or after the monthly timepoint.
If the target date for the second INVEGA SUSTENNA injection (one week ± 2 days) is missed, the recommended reinitiation depends on the length of time which has elapsed since the patient's first injection.
Missed second initiation dose (< 4 weeks from first injection). If less than 4 weeks have elapsed since the first injection, then the patient should be administered the second injection of 100 mg in the deltoid muscle as soon as possible. A third INVEGA SUSTENNA injection of 75 mg in either the deltoid or gluteal muscles should be administered 5 weeks after the first injection (regardless of the timing of the second injection). The normal monthly cycle of injections in either the deltoid or gluteal muscle of 25 mg to 150 mg based on individual patient tolerability and/or efficacy should be followed thereafter.
Missed second initiation dose (4-7 weeks from first injection). If 4 to 7 weeks have elapsed since the first injection of INVEGA SUSTENNA, resume dosing with two injections of 100 mg in the following manner: a deltoid injection as soon as possible followed by another deltoid injection one week later, then resumption of the normal monthly cycle of injections in either the deltoid or gluteal muscle of 25 mg to 150 mg based on individual patient tolerability and/or efficacy.
Missed second initiation dose (> 7 weeks from first injection). If more than 7 weeks have elapsed since the first injection of INVEGA SUSTENNA, initiate dosing as described for the initial recommended initiation of INVEGA SUSTENNA previously.
Missed maintenance dose (1 month to 6 weeks). After initiation, the recommended injection cycle of INVEGA SUSTENNA is monthly. If less than 6 weeks have elapsed since the last injection, then the previously stabilized dose should be administered as soon as possible, followed by injections at monthly intervals.
Missed maintenance dose (> 6 weeks to 6 months). If more than 6 weeks have elapsed since the last injection of INVEGA SUSTENNA, the recommendation is as follows: For patients stabilized with doses of 25 to 100 mg: 1. A deltoid injection as soon as possible at the same dose the patient was previously stabilized on.
2. Another deltoid injection (same dose) one week later (day 8).
3. Resumption of the normal monthly cycle of injections in either the deltoid or gluteal muscle of 25 mg to 150 mg based on individual patient tolerability and/or efficacy.
For patients stabilized with 150 mg: 1. A deltoid injection as soon as possible at the 100 mg dose.
2. Another deltoid injection one week later (day 8) at the 100 mg dose.
3. Resumption of the normal monthly cycle of injections in either the deltoid or gluteal muscle of 25 mg to 150 mg based on individual patient tolerability and/or efficacy.
Missed maintenance dose (> 6 months). If more than 6 months have elapsed since the last injection of INVEGA SUSTENNA, initiate dosing as described for the initial recommended initiation of INVEGA SUSTENNA previously.
Administration information: INVEGA SUSTENNA is intended for intramuscular use only. Inject slowly, deep into the muscle. Care should be taken to avoid inadvertent injection into a blood vessel. Each injection should be administered by a health care professional. Administration should be in a single injection. Do not administer the dose in divided injections. Do not administer intravascularly or subcutaneously.
The recommended needle size for administration of INVEGA SUSTENNA into the deltoid muscle is determined by the patient's weight. For those ≥ 90 kg (≥ 200 lb), the 1½ inch, 22-gauge needle is recommended. For those < 90 kg (< 200 lb), the 1-inch, 23 gauge needle is recommended. Deltoid injections should be alternated between the two deltoid muscles.
The recommended needle size for administration of INVEGA SUSTENNA into the gluteal muscle is the 1½-inch, 22 gauge needle. Administration should be made into the upper-outer quadrant of the gluteal area. Gluteal injections should be alternated between the two gluteal muscles.
Since paliperidone is the major active metabolite of risperidone, caution should be exercised when INVEGA SUSTENNA is coadministered with risperidone or with oral paliperidone for extended periods of time. Safety data involving concomitant use of INVEGA SUSTENNA with other antipsychotics is limited.
Special populations: Pediatrics (less than 18 years of age): Safety and effectiveness of INVEGA SUSTENNA in patients < 18 years of age have not been studied.
Elderly (65 years of age and older): In general, recommended dosing of INVEGA SUSTENNA for elderly patients with normal renal function is the same as for younger adult patients with normal renal function. As elderly patients may have reduced renal function, see Renal impairment as follows for dosing recommendations in patients with renal impairment.
Renal impairment: INVEGA SUSTENNA has not been systematically studied in patients with renal impairment (see Pharmacology: Pharmacokinetic under Actions). For patients with mild renal impairment (creatinine clearance ≥ 50 to < 80 mL/min), recommended initiation of INVEGA SUSTENNA is with a dose of 100 mg on treatment day 1 and 75 mg one week later, both administered in the deltoid muscle. Thereafter, follow with monthly injections of 50 mg in either the deltoid or gluteal muscle, adjusted within the range of 25 to 100 mg based on patient tolerability and/or efficacy.
INVEGA SUSTENNA is not recommended in patients with moderate or severe renal impairment (creatinine clearance < 50 mL/min).
Hepatic impairment: INVEGA SUSTENNA has not been studied in patients with hepatic impairment. Based on a study with oral paliperidone, no dose adjustment is required in patients with mild or moderate hepatic impairment. Paliperidone has not been studied in patients with severe hepatic impairment. (See Pharmacology: Pharmacokinetics under Actions.)
Other populations: No dose adjustment for INVEGA SUSTENNA is recommended based on gender, race, or smoking status. (For pregnant women and nursing mothers, see Use in Pregnancy & Lactation.)
Switching from other antipsychotic agents: There are no systematically collected data to specifically address switching patients with schizophrenia or schizoaffective disorder from other antipsychotics to INVEGA SUSTENNA, or concerning concomitant administration with other antipsychotics. For patients who have never taken oral paliperidone or oral or injectable risperidone, tolerability should be established with oral paliperidone or oral risperidone prior to initiating treatment with INVEGA SUSTENNA (see Dosage & Administration).
Previous oral antipsychotics can be immediately or gradually discontinued at the time of initiation of treatment with INVEGA SUSTENNA. INVEGA SUSTENNA should be initiated as described at the beginning of Dosage & Administration previously.
When switching patients currently at steady-state on a long-acting injectable antipsychotic, initiate INVEGA SUSTENNA therapy in place of the next scheduled injection. INVEGA SUSTENNA should then be continued at monthly intervals. The one-week initiation dosing regimen as described at the beginning of Dosage and Administration previously is not required.
Patients previously stabilized on different doses of paliperidone extended-release tablets can attain similar paliperidone steady-state exposure during maintenance treatment with INVEGA SUSTENNA monthly doses as depicted in Table 3. (See Table 3.)

Discontinuation of the previous antipsychotic should be made in accordance with the appropriate prescribing information. If INVEGA SUSTENNA is discontinued, its prolonged-release characteristics must be considered. As recommended with other antipsychotic medications, the need for continuing existing extrapyramidal symptoms (EPS) medication should be re-evaluated periodically.
