Adderall Tapering Guide
amphetamine/dextroamphetamine
Boxed Warning
High potential for abuse and dependence. Misuse may cause sudden death and serious cardiovascular adverse events.
Overview
Adderall (mixed amphetamine salts) is a stimulant medication approved for attention-deficit/hyperactivity disorder (ADHD) and narcolepsy. It contains a 3:1 ratio of dextroamphetamine to levoamphetamine salts.
IR: 5, 7.5, 10, 12.5, 15, 20, 30mg; XR: 5, 10, 15, 20, 25, 30mg
IR tablets: 5mg, 7.5mg, 10mg, 12.5mg, 15mg, 20mg, 30mg; XR capsules: 5mg, 10mg, 15mg, 20mg, 25mg, 30mg
Category C (risk cannot be ruled out)
Mechanism of Action
Amphetamines increase synaptic dopamine and norepinephrine via reverse transport through DAT and NET, inhibition of monoamine oxidase, and promotion of vesicular release. Effects on prefrontal cortex underlie therapeutic action in ADHD.
Taper Notes
Adderall withdrawal includes rebound fatigue, low mood, increased appetite, and cognitive slowing. A staged taper using IR fractions, XR strengths, or compound pharmacy formulations can soften the landing.
Hyperbolic Tapering Guidance
Stimulant withdrawal is typically not medically dangerous but can be subjectively severe. Slow stepwise reductions (e.g., 25% per 1-2 weeks) and matching reductions to functional demands (work, school) reduce rebound. Monitor mood — depressive symptoms can be marked in the first 2 weeks.

Tapering Protocol
Evidence-based phased reduction schedule. Always taper under medical supervision.
| Phase | Duration | Notes |
|---|---|---|
| Initial reductions | 1-2 weeks | Reduce by 25% of total daily dose. For XR users, switch to IR equivalents to enable finer reductions. |
| Middle reductions | 2-3 weeks | Continue 25% reductions every 1-2 weeks. Adjust dosing schedule to match work/school demands. |
| Lower-dose reductions | 2-4 weeks | Below 10mg/day, smaller increments via tablet splitting or compounded liquid help. |
| Final discontinuation | 1-2 weeks | Final cuts to off. Plan low-demand window for rebound period. |
Withdrawal Timeline
Hours after the last dose (post-dose crash) or 1-2 days after a dose reduction
3-7 days
Acute rebound resolves within 1-2 weeks
Anhedonia, low motivation, and sleep changes can persist 2-8 weeks
Community Tips
Practical insights shared by members tapering Adderall. Not medical advice — always consult your prescriber.
- 1Plan your taper around a low-demand period — the first 2 weeks off can hit hard with fatigue, hunger, and low motivation.
- 2Switch from XR to IR before reducing — IR gives you more granular control over the daily dose curve.
- 3Sleep, hydration, and protein-forward eating in the rebound window are non-negotiable; appetite changes are not in your head.
- 4If you are tapering because of cardiovascular concerns or psychosis risk, do not improvise — work with your prescriber on an appropriate pace.
Common Withdrawal Symptoms
Interactions & Safety
Drug Interactions
- MAOIs — contraindicated (hypertensive crisis risk)
- Serotonergic agents (SSRIs, SNRIs, TCAs, tramadol, MDMA) — serotonin syndrome risk
- Antihypertensives — reduced efficacy
Food Interactions
- Acidic foods/juices reduce absorption (citrus, vitamin C)
- Alkalinizing agents (sodium bicarbonate) increase amphetamine levels
- Avoid combining with high-dose caffeine
Contraindications
- Concurrent or recent (within 14 days) MAOI use
- Advanced arteriosclerosis, symptomatic cardiovascular disease
- Moderate-to-severe hypertension
Toxicity
Cardiovascular events (sudden death in patients with structural cardiac abnormalities), psychosis, mania, serotonin syndrome (with serotonergic agents), seizures, severe dependence, and growth suppression in children.
Pharmacokinetics
ADME Profile
IR: Tmax ~3 hours. XR: dual-pulse release, Tmax ~7 hours. Food does not significantly affect total exposure but can delay Tmax.
~3-4 L/kg
Hepatic, primarily via CYP2D6 to 4-hydroxyamphetamine and other metabolites. Some renal excretion of unchanged drug, increased by acidic urine.
Renal (~30% unchanged at neutral urine pH; up to 70% in acidic urine).
~16-20%
Variable, urine pH-dependent
