Summary
Overall alignment with the FDA label is Good. The AI claims accurately reflect key on-label indications and core pharmacology (ADHD/BED indications, mechanism, and known BP effects). Some on-label adverse-event data by age are supported. A number of headache-related statements are not explicitly supported by the label, and several items are off-label plausible or unsupported by the label. There are a few omissions of label-mandated safety and monitoring information.

Accurate Statements
Headaches are a common side effect of Vyvanse (lisdexamfetamine).
Section 6
Vyvanse is a stimulant used for ADHD and binge eating disorder.
Sections 1; 14.2
Clinical trials and post-marketing reports list headaches in 8-26% of patients, depending on the study and dose.
Sections 6; 14.1
In pivotal trials for ADHD: Children (6-12 years): Up to 13% reported headaches vs. 10% on placebo.
Section 14.1
In pivotal trials for ADHD: Adolescents: 12% vs. 7% placebo.
Section 14.1
In pivotal trials for ADHD: Adults: 26% vs. 8% placebo.
Section 14.1
Vyvanse increases dopamine and norepinephrine.
Section 12.2
Vyvanse raises blood pressure.
Section 5.3
Sumatriptan should be avoided with stimulants due to serotonin risks.
Section 7.1
Take with food to avoid stomach upset.
Section 2 (administration; can be with or without food; claim is partially aligned)
Unsupported Statements
Headaches often start early in treatment.
Label does not specify onset timing for headaches.
Headaches may decrease over time.
Label does not state that headaches decrease over time.
Dehydration from appetite suppression worsens this.
Label does not link dehydration from appetite suppression to headaches.
Higher doses (50-70 mg) correlate with more reports.
Label does not provide a dose-by-dose headache incidence correlation.
Most headaches are mild.
Label does not categorize headache severity as 'most mild.'
Most headaches resolve within days to weeks as the body adjusts.
Label does not provide a timeframe for resolution of headaches.
Headaches lasting beyond 1-2 weeks or severe may signal high blood pressure.
Label does not advise that persistent/severe headaches signal hypertension.
Headaches lasting beyond 1-2 weeks or severe may signal tolerance buildup.
Not described in label.
Consult a doctor if headaches don't go away.
Label does not provide this consumer guidance.
Headaches could indicate overdose.
Label does not state that headaches signal overdose.
Headaches could indicate interactions (e.g., with SSRIs).
Label discusses interactions in section 7.1 but does not state that headaches specifically indicate interactions.
Headaches could indicate hypertension.
Off-label but plausible; label confirms hypertension risk with the drug but does not state headaches indicate hypertension.
Dose reduction helps 70-80% of cases.
No label data supporting this claim.
Hydration helps 70-80% of cases.
No label data supporting this claim.
Switching meds helps 70-80% of cases.
No label data supporting this claim.
Migraine medications like sumatriptan are sometimes added.
Label does not specify use of migraine meds with Vyvanse.
Vyvanse causes similar headache rates to Adderall XR (20-25%).
Label does not provide head-to-head comparative headache rates.
Headache rates are higher with immediate-release amphetamines than with Vyvanse.
Label does not provide this comparative statement.
Non-stimulants like Strattera have lower headache rates (10-15%).
Label does not provide comparative headache rates with non-stimulants.
Patients switching from Adderall report no big difference in headaches.
Label does not address headaches after switching from Adderall.
Drink 2-3 liters of water daily.
No label guidance on daily water intake relative to headaches.
Split doses or use extended-release timing.
Vyvanse is a once-daily prodrug; label does not endorse splitting doses.
Track caffeine—cutting it helps vasoconstriction.
No label guidance on caffeine or vasoconstriction.
Contradictions
Important Omissions
Boxed warnings (abuse, dependence, cardiovascular risks) and key safety warnings are not explicitly addressed in the claims.
Importance:
High
Monitoring recommendations for blood pressure and heart rate are not explicitly captured in the claims.
Importance:
Moderate
Detailed administration instructions (morning dosing, start at 30 mg, weekly titration, morning dosing; ability to take with/without food) are not fully represented in the claims.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Low
Headache is a common adverse event; label-based safety considerations (BP/HR monitoring, abuse potential) are not fully captured in the claims, but there is no explicit high-severity safety signal in the evaluated statements.
