Three most prescribed ADHD stimulants. Millions take one. Which is actually best? We reviewed the comparative evidence.
I was surprised by some of these findings when I first dug into the research.
Head-to-Head
| Feature | Ritalin | Adderall | Vyvanse |
|---|---|---|---|
| Effect size | 0.78 | 0.96 | 0.96 |
| Duration | 3-4hr IR, 8hr ER | 4-6hr IR, 10hr XR | 12-14hr |
| Onset | 20-30 min | 30-45 min | 60-90 min |
| Crash severity | Moderate | Significant | Mild |
| Abuse potential | Moderate | High | Low (prodrug) |
| Generic cost/month | $15-30 | $20-40 | $30-60 |
What Data Says
Amphetamines (Adderall/Vyvanse) are slightly more effective than methylphenidate (Ritalin) on average. The 2018 Lancet meta-analysis (Cortese et al., 52,000 participants) confirmed this for adults.

But 30% of patients respond better to methylphenidate. The only way to know is to try both.
In my experience, the biggest mistake people make is
Which to Try First?
- Most psychiatrists start with: Vyvanse or Adderall XR
- Side effects bad? Switch to methylphenidate class
- Cost matters? Generic Ritalin or Adderall IR $15-30/month
- Abuse concern? Vyvanse (prodrug, cannot be snorted)
The Crash Problem
Adderall IR is notorious for the crash. Vyvanse was designed to solve this with a smoother curve. If Adderall crashes ruin your evenings, Vyvanse is the upgrade.
