The Short Version
Essentials
Adderall is a stimulant that helps you focus by increasing dopamine and norepinephrine in your brain. It's mainly prescribed for ADHD and narcolepsy.
It works fast, usually within 30-60 minutes and lasts 4-6 hours (immediate release) or 10-12 hours (XR/extended release).
The most common side effects are loss of appetite (35%) and trouble sleeping (30%). Most people also notice a faster heartbeat and dry mouth.
90% of ADHD drug trials were funded by pharmaceutical companies, and key ADHD researchers have financial ties to stimulant manufacturers. Independent studies show behavioral therapy has comparable long-term outcomes.

Non-Drug & Behavioral ADHD Approaches
Behavioral therapy shows comparable long-term outcomes in several large trials, may be preferred first-line for some patients
Important context: Evidence quality varies across these approaches. Some are well-studied with randomized controlled trial data; others are based on observational or smaller studies. These interventions are not guaranteed to replace medication for all patients. Discuss with your doctor whether any of these are appropriate for your clinical situation.

Risk of premature birth, low birth weight. Avoid if possible.
Passes into breast milk. Avoid.
Estrogen directly affects the brain's dopamine system, the same system ADHD medications work on. As estrogen fluctuates and drops during perimenopause, many women notice new attention difficulties, brain fog, and mood swings. Some women are first diagnosed with ADHD in their 40s when hormonal change, not a lifelong attention disorder, may be the actual cause. Ask your doctor about ruling out perimenopause before or alongside any ADHD evaluation.
Monitor growth; not recommended under age 3. Importantly: processed foods and excess sugars/carbs cause a blood sugar spike followed by an insulin overcorrection, blood sugar crashes, and the body releases adrenaline to compensate. This adrenaline surge causes shakiness, anxiety, restlessness, and inability to focus, symptoms that are frequently diagnosed as ADHD. A trial of whole foods with reduced sugar and processed carbs should always be attempted before or alongside medication in children.
Greater cardiovascular risk. Lower doses.
Use lower doses; monitor

Stopping This Medication Safely
Stimulant withdrawal causes significant fatigue, low mood, and increased sleep. Dopamine and norepinephrine systems need time to re-regulate after stimulant dependence.

- ·Published tapering protocols describe dose reduction of 25% every 1–2 weeks (e.g., 20mg → 15mg → 10mg → 5mg → stop)

Questions for Your Doctor

Questions to Ask
- 1.Has my child's diet been looked at first? High-sugar and processed-carb foods spike blood sugar, then the body overreacts with insulin and blood sugar crashes. The body then releases adrenaline to bring it back up, causing shakiness, anxiety, restlessness, and inability to focus. This can look exactly like ADHD. Has a dietary trial been tried before medication?
- 2.Have we tried behavioral therapy alongside or before medication?
- 3.What monitoring will we do for heart health?
- 4.Are there drug holidays on weekends or summers?
- 5.What are the long-term effects on growth?
Lab Tests to Request
- Blood pressure
- Heart rate
- Height/weight (children)
- Fasting blood sugar, to check for reactive hypoglycemia
- Anxiety screening
