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.
Combination of ethinyl estradiol and desogestrel: ethinyl estradiol suppresses gonadotropin release, inhibiting ovulation; desogestrel (progestin) causes cervical mucus thickening and endometrial atrophy, preventing implantation.
Schizophrenia,Acute manic/mixed episodes associated with bipolar I disorder,Maintenance treatment of bipolar I disorder,Major depressive disorder (adjunctive therapy),Irritability associated with autistic disorder,Tourette's disorder
Prevention of pregnancy,Treatment of moderate acne vulgaris (in females ≥15 years with no contraindications)
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.
1 tablet (ethinyl estradiol 0.03 mg / levonorgestrel 0.15 mg) orally once daily for 21 days, followed by 7 placebo days.
Aripiprazole: 75 hours (range 48–146 h). Dehydro-aripiprazole: 94 hours (range 48–206 h). Steady state reached in 14 days.
Levonorgestrel: terminal elimination half-life 25±10 hours; ethinyl estradiol: 13±7 hours. Clinical context: steady-state concentrations achieved within 5-7 days; contraceptive efficacy requires consistent daily dosing.
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.
Ethinyl estradiol: primarily metabolized by CYP3A4; undergoes sulfation and glucuronidation. Desogestrel: rapidly converted to active metabolite etonogestrel via CYP2C9 and CYP2C19; further metabolism by CYP3A4.
Aripiprazole: ~25% renal, ~55% fecal; unchanged drug accounts for <1% renal. Dehydro-aripiprazole (active metabolite): excreted similarly.
Renal excretion of metabolites and unchanged drug: ~30% (levonorgestrel) and ~20% (ethinyl estradiol) in urine; biliary/fecal elimination: ~40-50% as conjugates and metabolites.
Aripiprazole: >99% bound to albumin and alpha-1-acid glycoprotein. Dehydro-aripiprazole: >99% bound.
Levonorgestrel: 98-99% bound to sex hormone-binding globulin (SHBG) and albumin; ethinyl estradiol: 98% bound to albumin.
Aripiprazole: 4.9 L/kg (IV). High Vd indicates extensive tissue distribution.
Levonorgestrel: Vd ~1.8 L/kg (suggesting extensive tissue distribution). Ethinyl estradiol: Vd ~2.4 L/kg.
Oral: 87% (absolute). Tablet and orally disintegrating tablet are bioequivalent.
Oral bioavailability: levonorgestrel ~100% (nearly complete); ethinyl estradiol ~45-50% (first-pass hepatic metabolism).
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 dose adjustment required for mild to moderate renal impairment. Contraindicated in severe renal disease or acute renal failure due to potential fluid retention.
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.
Contraindicated in severe hepatic dysfunction (Child-Pugh class B or C). Use caution in mild to moderate impairment (Child-Pugh A); monitor liver enzymes.
Not approved for patients <18 years; safety and effectiveness not established.
Not indicated for use before menarche. For postmenarchal adolescents, same dosing as adults (1 tablet daily, 21/7 regimen) after evaluation of risks.
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.
Not indicated for postmenopausal women. No specific geriatric dosing; consider increased risk of thromboembolism, cardiovascular disease, and metabolic effects in older women of reproductive age.
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.
Cigarette smoking increases risk of serious cardiovascular events from combined oral contraceptives. Risk increases with age (especially >35 years) and with number of cigarettes smoked. Women who use combined hormonal contraceptives should be strongly advised not to smoke.

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.
No significant food interactions. Alcohol does not affect efficacy but may increase risk of adverse effects such as nausea. Grapefruit juice has no known interaction. Avoid excessive alcohol consumption due to potential hepatotoxicity.
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).
ALTAVERA contains ethinyl estradiol and levonorgestrel. First trimester: Inadvertent exposure during organogenesis is associated with a very low absolute risk of cardiovascular defects (relative risk 1.2-1.4) and no consistent increase in other major malformations. Second and third trimesters: No known teratogenic effects, but theoretical risks from estrogenic effects (e.g., feminization of male fetus). Postnatal: No increased risk of long-term developmental effects from pregnancy exposure.
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.
Combined oral contraceptives may reduce milk production and quality, especially in early lactation. Ethinyl estradiol transfers into breast milk at low levels (M/P ratio approximately 0.1-0.2), excluding clinical effects in term infants. Levonorgestrel transfer is minimal (M/P ratio ~0.2-0.4). Use is generally avoided in breastfeeding women, especially during the first 6 weeks postpartum. Progestin-only methods are preferred.
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.
Contraindicated in pregnancy. No dose adjustment recommended because use is discontinued upon confirmed or suspected pregnancy. Pharmacokinetic changes in pregnancy (e.g., increased hepatic clearance, altered binding proteins) are not relevant for this indication.
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.
ALTAVERA is a combined oral contraceptive (COC) containing ethinylestradiol and levonorgestrel. It inhibits ovulation via suppression of gonadotropins. Counsel patients to take at the same time daily to maintain efficacy. Missed pill management: if missed within 12 hours, take immediately; if >12 hours, take last missed pill and use backup contraception for 7 days. Be aware of increased VTE risk, especially in smokers over 35. May reduce effectiveness of lamotrigine; monitor seizure control. Initiate on the first day of menses or first Sunday after onset.
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 one tablet daily at the same time each day, with or without food.,If you miss a pill by less than 12 hours, take it as soon as you remember. If more than 12 hours, take the missed pill and use a backup method (e.g., condoms) for the next 7 days.,Smoking increases your risk of serious cardiovascular side effects, especially if you are over 35 years old. Do not smoke while taking this medication.,Seek immediate medical attention if you experience sudden severe headache, chest pain, leg pain/swelling, or vision changes (symptoms of blood clots).,This medication does not protect against HIV or other sexually transmitted infections.,If you are taking lamotrigine or other anticonvulsants, tell your doctor; your seizure medication may be less effective.,Store at room temperature away from moisture and heat.
