Avoid use if QTc interval is > 450 msec or with concomitant use of drugs that prolong the QTc interval or inhibit CYP2D6. Reserve use for patients who do not show an acceptable response to adequate courses of treatment with other antipsychotic drugs. |
Thiothixene | Navane | Capsule: 1, 2, 5, 10 | 6–10 | 15–30 | 60 | Smoking may reduce levels via CYP1A2 induction. |
Trifluoperazine | Stelazine | Tablet: 1, 2, 5, 10 | 4–10 | 15–20 | 50 | Smoking may reduce levels via CYP1A2 induction. |
Second-generation antipsychotics | ||||||
Aripiprazole | Abilify | Tablet: 2, 5, 10, 15, 20, 30 | 10–15 | 10–15 | 30 | Adjust dose if a poor CYP2D6 metabolizer or with concomitant use of a CYP3A4 inhibitor, CYP3A4 inducer, or CYP2D6 inhibitor. Tablet and oral solution may be interchanged on a mg-per-mg basis, up to 25 mg. Doses using 30 mg tablets should be exchanged for 25 mg oral solution. Orally disintegrating tablets (Abilify Discmelt) are bioequivalent to the immediate-release tablets (Abilify). Mycite tablet cannot be split or crushed. |
Tablet, disintegrating: 10, 15 | ||||||
Tablet with ingestible event marker (Mycite): 2, 5, 10, 15, 20, 30 | ||||||
Solution: 1/mL (150 mL) | ||||||
Asenapine | Saphris | Tablet, sublingual: 2.5, 5, 10 | 10 | 20 | 20 | Consider dose adjustment in smokers and with concomitant use of CYP1A2 inhibitors. Do not split, crush, or swallow. Place under tongue and allow to dissolve completely. Do not eat or drink for 10 minutes after administration to ensure absorption. |
Asenapine | Secuado | Transdermal system: 3.8 mg/ 24 hours, 5.7 mg/24 hours, 7.6 mg/24 hours | 3.8 | 3.8–7.6 | 7.6 | Consider dose adjustment in smokers and with concomitant use of CYP1A2 inhibitors. A dose of 3.8 mg/24 hours corresponds to 5 mg twice daily of sublingual asenapine; 7.6 mg/24 hours corresponds to 10 mg twice daily of sublingual asenapine. Apply to clean, dry, and intact skin on the upper arm, upper back, abdomen, or hip; rotate sites when applying a new transdermal system. Do not cut. Do not apply external heat sources to the transdermal system. |
Brexpiprazole | Rexulti | Tablet: 0.25, 0.5, 1, 2, 3, 4 | 1 | 2–4 | 4 | Adjust dose if a poor CYP2D6 metabolizer or with concomitant use of moderate/strong CYP2D6 inhibitors, strong CYP3A4 inhibitors, or strong CYP3A4 inducers. |
Cariprazine | Vraylar | Capsule: 1.5, 3, 4.5, 6 | 1.5 | 1.5–6 | 6i | Adjust dose with concomitant use of a strong CYP3A4 inhibitor or inducer. |
Clozapine | Clozaril, FazaClo, Versacloz | Tablet: 25, 50, 100, 200 | 12.5 –25 | 300–450e | 900 | Prescribers must complete clozapine REMS education (www.clozapinerems.com) and follow requirements for a baseline CBC and ANC and for ANC monitoring before and during treatment. When initiating clozapine, increase in 25–50 mg/day increments for 2 weeks, then further increments not exceeding 100 mg up to twice weekly. For treatment interruptions of 2 or more days, restart at 12.5 mg once or twice daily. Retitration can occur more rapidly than with initial treatment. With treatment interruptions of more than 30 days, recommendations for initial titration and monitoring frequency should be followed. Adjust dose with concomitant use of strong CYP1A2 inhibitors and with strong CYP3A4 inducers. Smoking reduces clozapine levels via CYP1A2 induction. Clozapine levels can be informative in making dose adjustments.j |
Tablet, disintegrating: 12.5, 25, 100, 150, 200 | ||||||
Oral suspension: 50/mL (100 mL) | ||||||
Iloperidone | Fanapt | Tablet: 1, 2, 4, 6, 8, 10, 12 | 2 | 12–24 | 24 | Titrate slowly (no more than 4 mg/day increase in dose). Follow initial titration approach if more than 3-day gap in treatment. Adjust dose with concomitant use of strong CYP2D6 or CYP3A4 inhibitors and reduce dose by 50% in CYP2D6 poor metabolizers. |
Lurasidone | Latuda | Tablet: 20, 40, 60, 80, 120 | 40 | 40–120 | 160 | Administer with food (≥ 350 calories). Adjust dose for concomitant use of moderate to strong CYP3A4 inhibitors or inducers. |
Olanzapine | Zyprexa | Tablet: 2.5, 5, 7.5, 10, 15, 20 | 5–10 | 10–20 | 20k | Short-acting IM formulation is used primarily for agitation, with usual dose of 2.5–10 mg IM and maximum dosage of 30 mg/day. Administer IM slowly, deep into muscle. Do not use subcutaneously. Concomitant use of IM olanzapine with parenteral benzodiazepines is not recommended because of potential for excessive sedation and cardiorespiratory depression. Smokers may require a 30% greater daily dose than nonsmokers because of CYP1A2 induction. Women may need lower daily doses. Approximately 40% of an oral dose is removed by first-pass metabolism as compared with IM dose. IM elimination half-life is ~1.5 times greater in the elderly. Oral dissolving tablet dissolves rapidly in saliva and may be swallowed with or without liquid. Olanzapine may be administered with or without food/meals. |

Paliperidone | Invega | Tablet, extended release: 1.5, 3, 6, 9 | 6 | 3–12 | 12 | If exceeding 6 mg daily, increases of 3 mg/day are recommended at intervals of more than 5 days, up to a maximum of 12 mg/day. Uses OROS; do not split or crush tablet. Use of extended-release tablet is not recommended with preexisting severe gastrointestinal narrowing disorders. Tablet shell is expelled in the stool. |
Quetiapine | Seroquel | Tablet, immediate release: 25, 50, 100, 200, 300, 400 | Immediate release: 50 | 400–800 | 800 | Dosage is once daily for extended release and divided dosing for immediate release. Do not split or crush extended-release tablets. Immediate-release tablets are marginally affected by food, whereas extended-release tablets are significantly affected by a high-fat meal. Give extended-release tablets without food or with < 300 calories. Retitrate for gap in treatment of more than 1 week. Adjust dose for concomitant use of strong CYP3A4 inhibitors or inducers. |
Tablet, extended release: 50, 150, 200, 300, 400 | Extended release: 300 | |||||
Risperidone | Risperdal | Tablet: 0.25, 0.5, 1, 2, 3, 4 | 2 | 2–8 | 8l | Use lower initial doses and slower titration rates with CrCl < 30 mL/min or severe hepatic impairment (Child-Pugh class C). Fraction of free risperidone is increased with hepatic impairment, and the initial starting dose is 0.5 mg twice daily, which may be increased in increments of 0.5 mg or less, administered twice daily. With renal or hepatic impairment, increase in intervals of 1 week or more for doses > 1.5 mg twice daily. Adjust dose with concomitant use of inducers or inhibitors of CYP2D6. Check labeling for compatible liquids with oral solution. Do not split or crush oral disintegrating tablets.

Effect of food on bioavailability | Food affects maximal concentration. Administer with food. Swallow tablets whole and do not chew, crush, or break. | Unaffected by food | Can be taken with or without food. High-fat meals decrease the Cmax and AUC for valbenazine, but values for the active metabolite (α-HTBZ) are unchanged. |
Commentsc | Give in divided doses; increase from initial dose of 12 mg/day by 6 mg/week to maximum dose of 48 mg/day. Retitrate dose for treatment interruptions of more than 1 week. | Give in divided doses; increase from initial dose of 25–50 mg/day by 12.5 mg/week to maximum of 150–200 mg/day. Retitrate dose for treatment interruptions of more than 5 days. | Initiate at 40 mg/day and increase to 80 mg/day after 1 week. Continuation of 40 mg/day may be considered for some patients. |
Follow product labeling if switching from tetrabenazine to deutetrabenazine. Do not exceed total daily dosage of 36 mg/day (18 mg/dose) in poor CYP2D6 metabolizers or patients taking a strong CYP2D6 inhibitor. | Test for CYP2D6 metabolizer status before giving doses > 50 mg/day. | Use is not recommended with strong CYP3A4 inducer. A reduced dose is recommended with concomitant use of strong CYP3A4 or CYP2D6 inhibitors or in poor CYP2D6 metabolizers. | |
Assess ECG before and after increasing the daily dose above 24 mg in patients at risk for QTc prolongation. | Do not exceed 50 mg/day in poor metabolizers or in patients treated with a strong inhibitor of CYP2D6. | Avoid use in patients with congenital long QT syndrome, with arrhythmias associated with a prolonged QT interval, or with other risks for QTc prolongation (e.g., drugs known to prolong QTc intervals, reduced metabolism via CYP2D6 or CYP3A4). | |
