6.1 Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical Trials Experience with Amfetamine in Pediatric Patients with ADHD
There is limited experience with Amfetamine in controlled trials. Based on this limited experience, the adverse reaction profile of Amfetamine appears similar to other amphetamine extended-release products. The most common (≥2% in the Amfetamine group and greater than placebo) adverse reactions reported in the Phase 3 controlled study conducted in 108 patients with ADHD (aged 6–12 years) were: epistaxis, allergic rhinitis and upper abdominal pain.
|Preferred Term|| Amfetamine |
| Placebo |
|Respiratory, thoracic and mediastinal disorders|
|Abdominal pain upper||3.8%||2.1%|
6.2 Postmarketing Experience
The following adverse reactions have been identified during post approval use of other amphetamine products. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Endocrine: frequent or prolonged erections.
Musculoskeletal, Connective Tissue, and Bone Disorders: rhabdomyolysis.
Psychiatric Disorders: dermatillomania.
