Oral: 10-15 mg once daily; dose range 5-30 mg/day; titrate based on response and tolerability. The MYCITE sensor is applied to the tablet; the patch and app are for adherence monitoring only.
10 mg orally once daily; may increase to 20 mg once daily after at least 1 week.
Aripiprazole: 75 hours (range 48–146 h). Dehydro-aripiprazole: 94 hours (range 48–206 h). Steady state reached in 14 days.
27-32 hours (mean ~30 h); steady state reached in ~1 week; linear kinetics at therapeutic doses.
Aripiprazole is metabolized primarily by CYP2D6 and CYP3A4. The major active metabolite is dehydro-aripiprazole (formed by CYP2D6). Phase I reactions include dehydrogenation and hydroxylation. Phase II glucuronidation of hydroxylated metabolites occurs.
Primarily hepatic via CYP3A4 and CYP2C19; active metabolite S-desmethylcitalopram.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Primarily renal (approx. 80% as metabolites, 8% as unchanged drug); biliary/fecal elimination accounts for ~15%.
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
Approximately 56% bound to plasma proteins (mainly albumin and alpha-1-acid glycoprotein).
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
12-26 L/kg (mean ~20 L/kg); extensive extravascular distribution consistent with high lipophilicity.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
Oral: approximately 80% (range 60-90%) after a single dose; food does not significantly affect absorption.
No dose adjustment required for mild to moderate renal impairment (Cr Cl ≥15 m L/min). Not recommended for severe renal impairment (Cr Cl <15 m L/min) due to lack of data.
No dosage adjustment for mild to moderate impairment. Not recommended for severe impairment (Cr Cl <20 m L/min).
Child-Pugh Class A or B: No dose adjustment necessary. Child-Pugh Class C: Use with caution; maximum dose 10 mg/day due to increased exposure.
For Child-Pugh class A or B: 10 mg orally once daily. Use caution in severe impairment (Child-Pugh class C); limited data.
Not approved for patients <18 years; safety and effectiveness not established.
Adolescents 12-17 years: 10 mg orally once daily. Children <12 years: not approved.
No specific dose adjustment; use lower starting doses (e.g., 5 mg/day) due to increased sensitivity and risk of adverse effects, especially orthostatic hypotension and tardive dyskinesia.
Initial 5 mg orally once daily; maximum 10 mg once daily.
WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS. Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.
Increased risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders.

Hypersensitivity to aripiprazole or any component of the formulation,Concurrent use with ziprasidone (QT prolongation risk)
Concurrent use of MAOIs or within 14 days of discontinuing MAOI,Concomitant use of pimozide,Hypersensitivity to escitalopram or citalopram,QT prolongation or congenital long QT syndrome (for citalopram, caution for escitalopram)
No specific food interactions are reported for the sensor component. Aripiprazole can be taken with or without food. However, avoid excessive alcohol consumption as it may increase central nervous system depression or worsen side effects. Grapefruit and grapefruit juice do not significantly interact with aripiprazole metabolism (CYP3A4 minor pathway); no restriction needed.
Grapefruit juice may increase escitalopram exposure; avoid concurrent use. Alcohol can potentiate central nervous system depression; limit or avoid alcohol consumption. No significant food interactions; may be taken with or without food.
First trimester: Limited human data; animal studies show developmental toxicity (reduced fetal weight, delayed ossification) at doses similar to human exposure. Second/third trimester: Neonates exposed to antipsychotics (including aripiprazole) during late pregnancy may experience extrapyramidal symptoms and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, feeding disorder).
First trimester: Epidemiologic studies have shown a small increased risk of congenital cardiac defects (primarily ventricular septal defects) with exposure, with an absolute risk of approximately 1-2%. Second/third trimester: Late pregnancy exposure may increase risk for persistent pulmonary hypertension of the newborn (PPHN) and serotonin syndrome in the neonate. Third trimester use may lead to neonatal adaptation syndrome including irritability, respiratory distress, and feeding difficulties.
Aripiprazole is present in human breast milk; limited data suggest infant serum levels are low but can vary. M/P ratio not established. Caution advised; monitor infant for sedation, irritability, and feeding problems.
Escitalopram is excreted into human breast milk with a milk-to-plasma ratio (M/P) of approximately 2.0. Infant serum levels are typically low, but some cases of adverse effects such as irritability, feeding problems, and sleep disturbance have been reported. The American Academy of Pediatrics considers escitalopram compatible with breastfeeding, but caution is advised, especially in premature or compromised infants.
No specific dose adjustment recommended; however, pregnancy may alter aripiprazole pharmacokinetics (decreased exposure due to increased volume of distribution and clearance). Monitor clinical response and consider dose adjustment if efficacy or tolerability changes. Use lowest effective dose.
Pharmacokinetic changes during pregnancy (increased volume of distribution, increased clearance) may require dose adjustments. Escitalopram clearance increases by approximately 50% in the third trimester. Dose increases may be needed to maintain efficacy, with gradual reduction postpartum to pre-pregnancy dose over 2-4 weeks. Therapeutic drug monitoring of escitalopram and its metabolite S-DCT is recommended if available, targeting trough levels of 15-80 ng/m L.
Abilify My Cite is aripiprazole tablets embedded with an ingestible sensor (Ingestible Event Marker, IEM) that communicates with a wearable patch to record medication ingestion. It is used for schizophrenia, bipolar I disorder, and as adjunctive therapy for major depressive disorder. The sensor does not monitor drug levels or efficacy; it only confirms ingestion. Ensure the patient has a compatible smartphone and the My Cite app. The patch must be replaced weekly. Avoid MRI, CT, or diathermy near the patch; remove if undergoing these procedures. Monitor for aripiprazole side effects: akathisia, metabolic changes, tardive dyskinesia, and neuroleptic malignant syndrome. The ingestible sensor contains copper, magnesium, and silicon; allergy risk is low but possible.
LEXAPRO (escitalopram) is the S-enantiomer of citalopram with less cytochrome P450 inhibition, minimizing drug interactions compared to racemic citalopram. QT prolongation risk is dose-dependent; maximum dose is 20 mg/day. Avoid co-administration with MAOIs and other serotonergic drugs due to serotonin syndrome risk. Abrupt discontinuation may cause withdrawal symptoms; taper over 1-2 weeks. Onset of therapeutic effect is 2-4 weeks. Use with caution in hepatic impairment (max dose 10 mg) and elderly patients.
Take Abilify My Cite by mouth as directed. The sensor in the tablet activates upon contact with stomach fluid. Wear the My Cite patch on your left upper abdomen, replacing it weekly. Use the My Cite app to scan the tablet's QR code and confirm ingestion. Do not crush or chew the tablet. If a dose is missed, take it as soon as remembered unless it is close to the next dose. Do not double doses.,The patch is not MRI compatible; remove it before any MRI, CT scan, or diathermy procedure. Inform all healthcare providers that you use this system. The patch contains no latex. You may feel a mild sensation when the patch communicates with your phone. Keep your phone nearby (within Bluetooth range) for recording.,Common side effects of aripiprazole include nausea, vomiting, constipation, headache, dizziness, insomnia, restlessness, and weight gain. Seek medical attention for severe muscle stiffness, fever, confusion, irregular heartbeat, or suicidal thoughts. Avoid alcohol and activities requiring mental alertness until you know how this medication affects you.,The ingestible sensor is generally safe, but if you have a sensitivity to copper, magnesium, or silicon, discuss with your doctor. The patch may cause skin irritation; if it persists, stop use and contact your provider.,Do not rely solely on the app to confirm ingestion; it is not a substitute for clinical judgment. Store tablets at room temperature, away from moisture and heat. Keep out of reach of children.
Take LEXAPRO once daily, either in the morning or evening, consistently with or without food.,Do not stop taking this medication suddenly; consult your doctor for a gradual dose reduction to avoid withdrawal symptoms.,Inform your doctor of all medications you are taking, especially MAOIs (e.g., linezolid, methylene blue), other antidepressants, and blood thinners.,Avoid alcohol and grapefruit juice as they may increase side effects.,Contact your doctor immediately if you experience suicidal thoughts, serotonin syndrome symptoms (e.g., agitation, hallucinations, rapid heart rate, fever, muscle stiffness), or prolonged QT interval symptoms (e.g., palpitations, fainting).,It may take several weeks to feel the full benefit; continue taking as prescribed.,Monitor for worsening depression or anxiety, especially during the first few months of treatment.,If pregnant or planning to become pregnant, discuss risks with your doctor (may cause neonatal complications).
