(Cast your vote in the comments section below!)
📌 Background
The use of ADHD medications during pregnancy is increasing worldwide. Concerns remain about their potential long-term effects on children, particularly the risk of neurodevelopmental disorders (NDDs) such as ADHD or autism spectrum disorder (ASD). While earlier studies suggested no significant risks, evidence has been limited and fragmented, especially for non-stimulants like atomoxetine.
🧪 Study Design
Population: 861,650 children born in Sweden (2008–2017)
Exposure groups:
Continued ADHD medication during pregnancy
Discontinued before pregnancy
Unexposed (no medication)
Medications studied: Methylphenidate, amphetamines (including lisdexamfetamine/dexamfetamine), and atomoxetine
Outcomes: Any NDD, ADHD, or ASD diagnosis in offspring (≥ age 3)
Analysis: Adjusted Cox regression, sibling comparison, and meta-analysis combining Swedish + Danish data
📊 Key Results
No increased risk of any NDD, ADHD, or ASD in exposed children compared to those whose mothers discontinued treatment:
Any NDD: HR 0.95 (95% CI 0.82–1.11)
ADHD: HR 0.92 (95% CI 0.78–1.08)
ASD: HR 0.86 (95% CI 0.63–1.18)
Consistent findings across:
Medication type (methylphenidate, amphetamines, atomoxetine)
Timing (1st, 2nd, 3rd trimester)
Duration of exposure
Meta-analysis (Sweden + Denmark): pooled HR for any NDD = 1.00 (95% CI 0.83–1.20)
🩺 Clinical Implications
Results provide reassurance that ADHD medications—including methylphenidate, amphetamines, and atomoxetine—do not increase long-term risk of NDDs in children.
Supports the view that women who require ADHD medication during pregnancy do not need to discontinue treatment solely out of concern for offspring neurodevelopmental outcomes.
Methylphenidate remains the best studied, but evidence for amphetamines and atomoxetine is now expanding.
Important for updating clinical guidelines and counseling expectant mothers with ADHD.
⚖️ Limitations
Possible residual confounding (e.g., maternal lifestyle, genetics).
Smaller sample sizes for amphetamines and atomoxetine.
Registry-based data may underestimate exposure if medication adherence was inconsistent.
✅ Clinical Takeaway
This large, robust population-based study confirms and extends prior findings:
- ADHD medication use during pregnancy does not increase the risk of long-term neurodevelopmental disorders in offspring.
- Clinicians can use this evidence to better guide discussions with patients balancing ADHD symptom management and pregnancy safety.
