Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Aripiprazole is a partial agonist at D2 and D3 dopamine receptors and 5-HT1A serotonin receptors, and an antagonist at 5-HT2A serotonin receptors. It also exhibits moderate affinity for histamine H1 receptors and alpha1-adrenergic receptors. The My Cite kit includes a sensor that detects tablet ingestion and transmits data to a wearable patch.
KALEXATE is a monoclonal antibody that binds to both soluble and membrane-bound human interleukin-6 (IL-6) receptors, inhibiting IL-6-mediated signaling. IL-6 is a pro-inflammatory cytokine implicated in the pathogenesis of rheumatoid arthritis and other inflammatory conditions.

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.
Aripiprazole: 75 hours (range 48–146 h). Dehydro-aripiprazole: 94 hours (range 48–206 h). Steady state reached in 14 days.
12-15 hours; prolonged in renal impairment (up to 30 hours in severe cases)
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.
KALEXATE is a monoclonal antibody; it is catabolized into small peptides and amino acids via general protein degradation pathways. No specific metabolic enzymes or pathways are involved.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Primarily renal (75-80% as unchanged drug); biliary/fecal (15-20%)
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
60-70% primarily to albumin
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
1.2-1.6 L/kg; indicates extensive extravascular distribution
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
Oral: 85-95%
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.
GFR >= 60 m L/min: no adjustment; GFR < 60 m L/min: use not recommended.
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.
Child-Pugh A: 5 mg once daily; Child-Pugh B: 2.5 mg once daily; Child-Pugh C: not recommended.
Not approved for patients <18 years; safety and effectiveness not established.
Not approved for pediatric use.
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.
No specific dose adjustment; monitor renal function.
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.
Risk of serious infections including tuberculosis, invasive fungal infections, and other opportunistic pathogens. Patients should be screened for latent tuberculosis prior to initiation. If serious infection develops, interrupt KALEXATE until infection is controlled.

Hypersensitivity to aripiprazole or any component of the formulation,Concurrent use with ziprasidone (QT prolongation risk)
Known hypersensitivity to KALEXATE or any of its excipients,Active infections including localized infections
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.
Avoid potassium-rich foods (bananas, oranges, potatoes, spinach, tomatoes, salt substitutes). Do not mix with fruit juices containing high potassium (e.g., orange, tomato). Maintain adequate fluid intake to prevent constipation.
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).
Kalexate (sodium polystyrene sulfonate) is not absorbed systemically and thus has no direct fetal exposure. However, electrolyte disturbances from maternal use (hypokalemia, hypernatremia) may indirectly affect fetal development. No specific teratogenic risk is documented; avoid severe maternal electrolyte imbalances.
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.
Kalexate is not absorbed from the gastrointestinal tract, so systemic concentrations are negligible. M/P ratio is not applicable. Considered compatible with breastfeeding, but monitor infant for electrolyte imbalance if maternal use is prolonged.
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.
Standard dosing (15-60 g orally per day) may be used in pregnancy. No pharmacokinetic changes requiring dose adjustment as the drug is not absorbed. However, monitor electrolytes more frequently due to pregnancy-related volume expansion and altered renal function.
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.
Kalexate (sodium polystyrene sulfonate) exchanges sodium for potassium in the gastrointestinal tract. Onset of action is 2-12 hours. Avoid in patients with hypokalemia, severe hypernatremia, or bowel obstruction. Monitor serum potassium and sodium levels regularly. Use with caution in patients with congestive heart failure or severe edema due to sodium load. Administer orally or as a retention enema; do not mix with fruit juices containing high potassium (e.g., orange juice).
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 this medication exactly as prescribed to lower high potassium levels.,Do not mix with orange juice or other high-potassium beverages.,Drink plenty of water with each dose to prevent constipation.,Report any signs of bowel obstruction (severe abdominal pain, vomiting, no bowel movements) immediately.,Notify your doctor if you experience irregular heartbeat, muscle weakness, or numbness/tingling.,This medication contains sodium; inform your doctor if you have heart failure or high blood pressure.
