Amphetamine side effects: what 7,975 FDA adverse event reports show
Drug class
Central Nervous System Stimulant
Who reports
7,975 reports · 84% serious · 3,899 with death outcome · 45% female
Used for
Amphetamine extended-release orally disintegrating tablets are a central nervous system (CNS) stimulant indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older . Limitat.
What it is
Amphetamine extended-release orally disintegrating tablets contain a 3 to 1 ratio of d- to l-amphetamine, a central nervous system stimulant. The labeled strengths reflect the amount of amphet.
Boxed warning
ABUSE, MISUSE, AND ADDICTION Amphetamine extended-release orally disintegrating tablets have a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. .
Causality screen of the 40 strongest signals
What the badges mean
- Labeled — boxed warning The term (or its clinical synonym) appears in the FDA boxed warning: causality is regulator-recognised and considered serious.
- Labeled (related wording) The label describes this effect under different wording (e.g. 'neutropenia' for 'neutrophil count decreased'). Treated as known.
- Reporting / coding artifact An administrative, monitoring or exposure term (product issue, off-label use, 'test normal', overdose...). Not a biological reaction; a high PRR here reflects how reports are coded.
- Lab value / disease marker A laboratory result, investigation or disease-activity marker (antibody positive, CRP abnormal, swollen joint count) not described in the label. These usually mirror the monitored disease or testing protocol rather than a drug effect; not screened further.
- Outcome field, not a reaction Death is a report outcome, not a reaction term. It is dominated by the underlying illness; see the seriousness profile and the boxed warning instead.
- Not in label — unassessed Not found in the label text, not an artifact pattern. This is a genuine candidate for a formal causality assessment (Bradford Hill / WHO-UMC); it has NOT had one here.
Strongest disproportionality signals
Flagged terms (PRR ≥ 2, χ² ≥ 4, n ≥ 10), ranked by PRR; infinite PRRs (no comparator reports) excluded. The EBGM column is a second, shrinkage-based estimate (MGPS) with its 5th percentile EB05 and the BCPNN IC025; a pair flagged by PRR alone is marked PRR-only and should be read as fragile. The strata column recomputes the PRR on serious reports only and flags pairs whose reports are unusually skewed by sex or come mostly from consumers rather than clinicians. 969 further terms are in the interactive explorer.

Unlabeled candidate signals
These flagged terms were not found in the FDA label text and do not match an artifact pattern. They are the pairs that would merit a structured assessment (temporality, dose-response, biological plausibility, consistency across databases, trial or cohort evidence). The screen has not done that; string-matching misses label wording, and a strong PRR can still be stimulated reporting, co-medication, or the disease itself.

Common questions
What are the most reported side effects of Amphetamine?
In FDA FAERS, the most frequently co-reported reaction terms for Amphetamine are toxicity to various agents, cardiac arrest, cardio-respiratory arrest, respiratory arrest, fatigue, headache. These are report counts, not rates: FAERS has no denominator, reporting is voluntary and uneven, and a term can be reported because of the illness being treated rather than the drug.
Does Amphetamine have an FDA boxed warning?
Yes. The current FDA label carries a boxed warning: ABUSE, MISUSE, AND ADDICTION Amphetamine extended-release orally disintegrating tablets have a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. .
Do FAERS signals prove that Amphetamine causes these side effects?
No. A disproportionality signal (PRR, ROR) means a reaction is reported more often with this drug than with others in the database. That can reflect a real effect, but also the disease being treated, stimulated reporting after news or litigation, co-medications, or how reports are coded. Causality needs temporality, dose-response, biological plausibility, consistency across data sources and, ideally, trial or cohort evidence. This page screens each term against the FDA label and ClinicalTrials.gov results; it does not establish causation.
