ADDERALL 12.5 vs BAFIERTAM
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall 12.5 is a combination of dextroamphetamine and amphetamine. It increases the levels of dopamine and norepinephrine in the central nervous system by inhibiting their reuptake and promoting their release from presynaptic neurons.
BAFIERTAM (monomethyl fumarate) is a prodrug that is rapidly hydrolyzed to monomethyl fumarate, which activates the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway, leading to upregulation of antioxidant response elements and cytoprotective proteins. It also modulates immune responses by shifting from a pro-inflammatory to an anti-inflammatory state.
Attention deficit hyperactivity disorder (ADHD),Narcolepsy (off-label)
FDA-approved: Treatment of relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease.,Off-label: None widely documented.
5-60 mg orally once or twice daily; immediate-release: initial 5 mg once or twice daily, increase by 5 mg weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly.
120 mg orally once daily.
The terminal elimination half-life of d-amphetamine is approximately 10–13 hours in adults (range 9–14 h) and 6–8 hours in children. Clinical context: Typically allows twice-daily dosing; extended-release formulations provide 8–12 hours of effect.
Approximately 12 hours (range 8–15 hours); permits twice-daily dosing in multiple sclerosis.
Amphetamine and dextroamphetamine are extensively metabolized in the liver via CYP2D6 and other pathways. The primary metabolites are 4-hydroxyamphetamine and 4-hydroxynorephedrine.
BAFIERTAM is a prodrug that is rapidly metabolized by esterases in the gastrointestinal tract, blood, and tissues to monomethyl fumarate. Monomethyl fumarate is further metabolized via the tricarboxylic acid (TCA) cycle, with no significant involvement of cytochrome P450 enzymes.
Approximately 30% of the dose is excreted unchanged in urine; the remainder is metabolized primarily via deamination and oxidation. Renal elimination of unchanged amphetamine is p H-dependent: acidic urine increases elimination, alkaline urine decreases it. Fecal excretion accounts for <5%.
Primarily via renal excretion as unchanged drug (approximately 80% of the dose); minimal biliary/fecal elimination (<5%).
Approximately 15–20% bound to plasma proteins, primarily albumin.
30–40% bound to plasma proteins, primarily albumin.
Mean volume of distribution is 3.5–4.6 L/kg, indicating extensive tissue distribution. Clinical meaning: Large Vd reflects sequestration in tissues (including brain), contributing to prolonged presence.
Approximately 0.5–0.7 L/kg; indicates distribution into total body water with limited tissue binding.
Oral bioavailability is highly variable, ranging from 75–100% for immediate-release tablets; food does not significantly affect overall absorption but may delay time to peak concentration. Extended-release capsules have bioavailability approximately 96% relative to immediate-release.
Oral: Approximately 50% (due to first-pass metabolism); administer with food to reduce GI irritation.
GFR 15-29 m L/min: reduce dose to 50% of usual; GFR <15 m L/min: use 50% of usual dose; hemodialysis: not removed, avoid use.
No dose adjustment required for GFR ≥30 m L/min. Not recommended for GFR <30 m L/min.
Child-Pugh A: no adjustment; Child-Pugh B: use 50% of usual dose; Child-Pugh C: avoid use.
Use with caution in hepatic impairment; reduce dose to 60 mg once daily in Child-Pugh Class B or C.
Immediate-release: 3-5 years: initial 2.5 mg once daily, increase by 2.5 mg weekly up to 40 mg/day; 6+ years: initial 5 mg once or twice daily, increase by 5 mg weekly up to 40 mg/day. Extended-release: 6-12 years: initial 10 mg once daily, increase by 10 mg weekly up to 30 mg/day; 13-17 years: initial 10 mg once daily, increase by 10 mg weekly up to 40 mg/day.
Not established in pediatric patients.
Start at lowest dose (5 mg immediate-release or 10 mg extended-release) and titrate slowly due to increased risk of adverse cardiovascular and CNS effects; monitor for hypertension, tachycardia, and agitation.
No specific dose adjustment; use with caution due to age-related decline in renal function.
Adderall has a high potential for abuse and dependence. Prolonged use may lead to drug dependence. Misuse may cause sudden death or serious cardiovascular adverse events.
No black box warning.
Risk of abuse and dependence,Serious cardiovascular events including sudden death, stroke, and myocardial infarction,Blood pressure and heart rate increases,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggression,Seizures in patients with seizure disorders,Visual disturbances,Growth suppression in children,Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk when used with serotonergic drugs
Lymphopenia: May cause reduction in lymphocyte counts; monitor complete blood count before and periodically during treatment.,Hypersensitivity reactions: Anaphylaxis and angioedema may occur; discontinue if severe.,Progressive multifocal leukoencephalopathy (PML): Reported in patients with prolonged lymphopenia; consider holding therapy if lymphocyte counts drop below 0.2 x 10^9/L.,Hepatic injury: Elevations of liver enzymes have been reported; monitor in patients with pre-existing liver disease.,Flushing and gastrointestinal events: Common; may be managed by taking with food or using aspirin.
Known hypersensitivity to amphetamine products or other sympathomimetic amines,Concomitant use with MAOIs or within 14 days of MAOI therapy,Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease including moderate to severe hypertension, advanced arteriosclerosis, symptomatic cardiovascular disease, or tachyarrhythmias
Known hypersensitivity to BAFIERTAM, monomethyl fumarate, or any excipient.,Concomitant use with dimethyl fumarate or other fumaric acid esters.
Avoid acidic foods and beverages (e.g., citrus fruits, soda) within 1 hour of administration as they may decrease absorption. High-fat meals may delay absorption of extended-release formulations. Avoid caffeine and other stimulants. Grapefruit juice may increase amphetamine levels.
Administer with food to reduce flushing and gastrointestinal adverse effects. Avoid alcohol consumption during treatment as it may exacerbate flushing. No specific dietary restrictions are required.
First trimester: Increased risk of congenital malformations, particularly cardiovascular defects (e.g., septal defects) and oral clefts based on amphetamine exposure. Second and third trimesters: risk of preterm delivery, low birth weight, and neonatal withdrawal syndrome (irritability, feeding difficulties, respiratory distress). Premature delivery and growth restriction have been reported.
BAFIERTAM (monomethyl fumarate) is contraindicated in pregnancy. Animal studies show malformations at subclinical doses. No human data; avoid in all trimesters due to teratogenic potential.
Contraindicated due to potential for infant toxicity. M/P ratio not established; amphetamine is excreted into breast milk in small amounts but may accumulate in breastfeeding infants. Adverse effects include irritability, poor feeding, and decreased weight gain.
No data on presence in human milk. M/P ratio unknown. Risk of infant exposure cannot be excluded. Discontinue breastfeeding or drug, considering importance to mother.
Pharmacokinetics altered: increased hepatic metabolism and renal clearance in pregnancy may reduce amphetamine exposure; however, safety data do not support dose adjustment. Use lowest effective dose only if necessary; consider alternative non-amphetamine therapies.
No dose adjustment data; contraindicated in pregnancy. If unintentional exposure occurs, discontinue immediately. Pharmacokinetic changes unknown but drug should not be used.
ADDERALL 12.5 mg is a fixed-dose combination of amphetamine and dextroamphetamine. Monitor for cardiovascular events, especially in patients with pre-existing heart conditions. Onset of action occurs within 30-60 minutes; duration of action is approximately 4-6 hours. Avoid late afternoon doses to prevent insomnia. Use with caution in patients with a history of drug abuse. May cause growth suppression in children; monitor height and weight. Do not crush or chew extended-release capsules.
BAFIERTAM (monomethyl fumarate) is a prodrug of monomethyl fumarate, indicated for relapsing forms of multiple sclerosis. Administer with food to reduce flushing and gastrointestinal adverse effects.
