Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall 10 contains a mixture of amphetamine salts (dextroamphetamine and levoamphetamine). Amphetamines are non-catecholamine sympathomimetic amines that promote the release of dopamine and norepinephrine from presynaptic neurons, inhibit their reuptake, and inhibit monoamine oxidase activity, thereby increasing extracellular levels of these neurotransmitters in the central nervous system.
Cabergoline is a long-acting dopamine D2 receptor agonist that inhibits prolactin secretion by the anterior pituitary gland.
Attention Deficit Hyperactivity Disorder (ADHD),Narcolepsy
Treatment of hyperprolactinemic disorders (e.g., amenorrhea, galactorrhea, infertility),Prolactin-secreting pituitary adenomas (microadenomas and macroadenomas)
10 mg orally once daily in the morning, with or without food; may increase by 5-10 mg weekly based on tolerability and response; usual effective dose 10-40 mg/day divided into 2-3 doses; maximum 60 mg/day.
0.25 mg orally twice weekly, up to 1 mg twice weekly; for hyperprolactinemia, initial 0.25 mg twice weekly, titrate by 0.25 mg every 4 weeks based on prolactin levels.
Terminal elimination half-life: dextroamphetamine 9-11 hours, levoamphetamine 11-14 hours (Adderall is a mixed salt). In adults, mean half-life ~10 hours; in children, slightly shorter (6-8 hours). Clinical context: steady-state reached in 2-3 days; dosing interval typically 4-6 hours for immediate-release.
Terminal elimination half-life is 63-68 hours in healthy subjects, allowing for once- or twice-weekly dosing. In hepatic impairment, half-life may be prolonged.
Amphetamine is metabolized primarily in the liver via cytochrome P450 enzymes, including CYP2D6, and undergoes deamination and oxidation to form inactive metabolites including 4-hydroxyamphetamine and norephedrine.
Extensively metabolized in the liver, primarily by hydrolysis and minor CYP3A4 involvement.
Renal: 70-80% (30-40% as unchanged amphetamine; remainder as deaminated and hydroxylated metabolites). Fecal: minimal (<5%). Biliary: negligible. Urinary p H affects excretion: acidic urine increases elimination, alkaline urine decreases.
Approximately 60-70% of the dose is excreted in feces (primarily as unchanged drug and metabolites), with about 20-30% excreted renally (mostly as metabolites).
Amphetamine: 15-40% bound to plasma proteins (primarily albumin). Binding is not extensive, thus significant free fraction available for distribution.
40-42% bound to plasma proteins, primarily albumin.
Apparent Vd: 3.0-4.0 L/kg (for total amphetamine). High Vd indicates extensive tissue distribution, including brain. Clinical meaning: loading dose may be needed for rapid effect; distribution half-life ~1 hour.
Approximately 100-150 L/kg, indicating extensive tissue distribution; Vd is large (≥100 L/kg) due to high lipophilicity and tissue binding.
Oral immediate-release: 100% (well-absorbed; first-pass metabolism minimal). Food delays absorption but does not affect extent. Extended-release: bioavailability similar to immediate-release with modified release profile.
Oral bioavailability is about 40-45% (range 30-60%) due to first-pass metabolism. No parenteral formulations are commonly used.
e GFR 15-29 m L/min: reduce dose by 50% and monitor for toxicity; e GFR <15 m L/min or dialysis: avoid use due to risk of accumulation; consider alternative therapy.
No dosage adjustment recommended for mild to moderate renal impairment (Cr Cl >10 m L/min); avoid use in severe renal impairment (Cr Cl <10 m L/min) due to lack of data.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: avoid use due to decreased clearance and increased risk of toxicity.
No specific guidelines; use with caution in severe hepatic impairment (Child-Pugh class C) as elimination may be reduced.
Children 3-5 years: 2.5 mg orally once daily; may increase by 2.5 mg weekly; usual range 2.5-20 mg/day divided 1-2 times. Children 6 years and older: initial 5 mg once daily; may increase by 5 mg weekly; usual range 5-40 mg/day divided 1-3 times; maximum 40 mg/day.
Not FDA approved for pediatric use; limited data: 0.025-0.05 mg/kg once weekly, titrated cautiously based on prolactin levels; maximum 0.1 mg/kg weekly.
Initiate at 2.5-5 mg orally once daily; titrate slowly in increments of 2.5-5 mg weekly; monitor for cardiovascular effects, insomnia, and weight loss; maximum 40 mg/day.
No specific adjustment recommended; start at lower end of dosing range (0.25 mg twice weekly) due to potential for increased sensitivity and age-related decline in renal function.
Potential for abuse and dependence. Amphetamines have a high potential for abuse, which may lead to dependence and serious cardiovascular adverse events. Misuse may cause sudden death and serious cardiovascular events.
Cabergoline is associated with an increased risk of cardiac valve regurgitation, especially at high doses used for Parkinson's disease. The risk appears lower at doses used for hyperprolactinemia, but caution is advised.
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems.,Blood pressure and heart rate increase; caution in hypertension and other cardiovascular conditions.,Psychiatric adverse events including exacerbation of psychosis, mania, and aggression.,Long-term suppression of growth in pediatric patients.,Peripheral vasculopathy including Raynaud's phenomenon.,Seizures: may lower seizure threshold.,Serotonin syndrome risk when co-administered with serotonergic drugs.
Cardiac valvulopathy: monitor with echocardiography before and during therapy,Pleural, pericardial, and retroperitoneal fibrosis,Postural hypotension,Impulse control disorders (e.g., pathological gambling, hypersexuality),Remission of prolactinomas may reduce pituitary function
Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Known hypersensitivity or idiosyncrasy to sympathomimetic amines,Glaucoma,Agitated states,History of drug abuse,During or within 14 days following the administration of monoamine oxidase inhibitors (hypertensive crises may occur)
Hypersensitivity to cabergoline or ergot derivatives,Uncontrolled hypertension,History of cardiac valvular disease,Pregnancy: use only if clearly needed (category B)
High-fat meals can delay absorption; avoid acidic foods (e.g., citrus, cola) within 1 hour of dosing as they decrease absorption. Avoid caffeine; may increase stimulant effects.
Avoid high-fat meals that may increase absorption variability. No specific food restrictions, but take consistently with meals to maintain stable levels. Grapefruit juice may theoretically increase cabergoline exposure (CYP3A4 inhibition); avoid excessive consumption.
Pregnancy Category C. First trimester: potential increased risk of congenital malformations (e.g., gastroschisis, oral clefts) based on limited human data. Second and third trimesters: risk of fetal growth restriction, preterm delivery, and neonatal withdrawal symptoms (irritability, poor feeding).
FDA Pregnancy Category B. No evidence of teratogenicity in animal studies; limited human data. In first trimester, theoretical risk of ergot alkaloid-induced uteroplacental vasoconstriction may cause fetal hypoxia; use only if benefit outweighs risk. Second and third trimesters: risk of postpartum hemorrhage and uterine atony if used for lactation suppression; avoid in pregnancy due to potential for fetal harm from dopamine agonist effects.
Excreted into breast milk; relative infant dose estimated at 2-4% of maternal weight-adjusted dose. M/P ratio not well established. Manufacturer recommends caution; potential for infant agitation, insomnia, and growth suppression.
Cabergoline suppresses lactation; contraindicated in breastfeeding women because it reduces milk production. If used, discontinue breastfeeding or avoid drug. M/P ratio not established; drug is excreted in rat milk, unknown in humans.
Increased plasma volume and enhanced hepatic metabolism may reduce amphetamine levels; dose adjustments should be individualized based on clinical response, but controlled studies lacking. Avoid abrupt discontinuation due to risk of withdrawal symptoms in mother and neonate.
No standard dose adjustment recommended; avoid use during pregnancy unless absolutely necessary (e.g., prolactinoma). Pregnancy may alter cabergoline pharmacokinetics (increased volume of distribution, decreased clearance) but specific dose modifications are not established. If used, monitor prolactin levels and clinical response.
Adderall 10 mg contains immediate-release amphetamine salts. Onset of action is 30-60 minutes, duration 4-6 hours. Monitor for appetite suppression, insomnia, and cardiovascular effects. Avoid in patients with structural cardiac abnormalities or history of substance abuse. Use with caution in hypertension or hyperthyroidism. Drug holidays may reduce tolerance.
Start with 0.25 mg twice weekly, titrate by 0.25 mg every 2-4 weeks based on prolactin levels and tolerability. Maximum dose typically 1 mg twice weekly. May cause orthostatic hypotension; caution when rising from supine position. Use lowest effective dose to minimize risk of valvulopathy, especially with cumulative doses >2 mg/day. Discontinue if signs of cardiac fibrosis. Monitor for impulse control disorders (e.g., hypersexuality, gambling). Avoid in patients with uncontrolled hypertension or pre-existing cardiac valvular disease.
Take exactly as prescribed; do not crush or chew tablets.,Take early in the day to prevent insomnia.,May cause weight loss; monitor growth in children.,Avoid alcohol and decongestants (risk of hypertensive crisis).,Report chest pain, palpitations, or shortness of breath immediately.,Do not drive if you feel dizzy or impaired.

No interactions on record
"Trazodone, a serotonin antagonist and reuptake inhibitor, and cabergoline, a dopamine D2 receptor agonist, exhibit opposing effects on the dopaminergic and serotonergic systems, potentially leading to reduced therapeutic efficacy and increased risk of adverse effects such as serotonin syndrome or dopaminergic toxicity. The combination may precipitate hypertensive crises or cardiac valvulopathy due to additive effects on 5-HT2B receptor activation by cabergoline, while trazodone's blockade of serotonin reuptake can exacerbate serotonin excess. Clinical outcomes include unpredictable blood pressure fluctuations, neuropsychiatric disturbances, and rare but serious cardiovascular events."
"Cabergoline, a dopamine D2 receptor agonist used for hyperprolactinemia, may inhibit the metabolism of methylene blue, a monoamine oxidase inhibitor (MAOI) used for methemoglobinemia. This interaction can lead to elevated methylene blue levels, increasing the risk of serotonin syndrome, characterized by hyperthermia, agitation, and neuromuscular abnormalities. Clinically, patients may present with confusion, tachycardia, and hypertension, necessitating cautious use."
"Cabergoline, a dopaminergic ergot derivative, acts as a vasoconstrictor via agonism of serotonin 5-HT2B and dopamine D1 receptors in vascular smooth muscle. Nadolol, a non-selective beta-blocker, inhibits beta-2 adrenergic receptor-mediated vasodilation, leaving alpha-adrenergic vasoconstriction unopposed. The combined vasoconstrictive effects can lead to additive peripheral and coronary vasoconstriction, potentially causing severe hypertension, myocardial ischemia, or Raynaud's phenomenon."
