Vyvanse is NOT used for erectile dysfunction
Vyvanse (lisdexamfetamine) is FDA-approved only for ADHD and binge eating disorder—it has no role in treating erectile dysfunction and may actually worsen sexual function. 1
Why This Matters
The FDA drug label for Vyvanse explicitly lists its approved indications as ADHD and binge eating disorder only 1. There is no mention of erectile dysfunction as an indication, and importantly, the safety data reveals that erectile dysfunction was observed in 2.6% of males taking Vyvanse versus 0% on placebo in adult ADHD trials 1. This means Vyvanse may actually cause erectile dysfunction rather than treat it.
Evidence-Based Treatment for ED
First-line treatment for erectile dysfunction should be oral PDE5 inhibitors (sildenafil, tadalafil, vardenafil, or avanafil) unless contraindicated 2. This is a strong recommendation based on high-quality evidence from the most recent AUA guidelines (2018).
The treatment algorithm is:
- First-line: PDE5 inhibitors with proper dosing instructions and titration 2
- Second-line: Intraurethral or intracavernosal alprostadil, vacuum erection devices 3, 4
- Third-line: Penile prosthesis implantation 2, 5
The Stimulant-Sexual Dysfunction Connection
Recent research (2025) demonstrates that stimulant medications like Vyvanse are actually linked to increased sexual dysfunction, particularly in males who report higher rates of erectile dysfunction 6. A 2021 study showed lisdexamfetamine improved early ejaculation but this was for a completely different sexual dysfunction, not ED 7.
Critical Caveat
Before treating ED with any medication, cardiovascular risk must be assessed 2. ED is a risk marker for cardiovascular disease as strong as smoking or family history of MI 2. Patients should be stratified into low, intermediate, or high cardiovascular risk categories, with high-risk patients requiring cardiac stabilization before ED treatment 3.
PDE5 inhibitors are absolutely contraindicated with nitrate therapy due to dangerous blood pressure drops 8.
