Summary
The response includes some label-supported information about approved uses, dizziness, somnolence, blurred vision, mechanism, and Schedule V status. However, it makes numerous label-unsubstantiated claims about athletic performance, specific neurotransmitters, dosing and sedation timing, performance studies, WADA rules, and alternative drugs. Several adverse-effect rates also do not match the rates reported in the supplied sections.
Category Scores
Accurate Statements
Lyrica is an anticonvulsant medication.
The label indicates Lyrica as adjunctive therapy for partial-onset seizures in patients 1 month of age and older, although it does not use the term “anticonvulsant.”
Lyrica is used to treat neuropathic pain.
The label supports this for neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, and spinal cord injury.
Pregabalin binds to voltage-gated calcium channels in the central nervous system.
The label states that pregabalin binds with high affinity to the alpha2-delta site, an auxiliary subunit of voltage-gated calcium channels, in CNS tissues.
Pregabalin can cause dizziness and somnolence, and can cause blurred vision.
The label reports dizziness and somnolence and warns that they may impair tasks such as driving or operating machinery; it also reports blurred vision.
Pregabalin is a Schedule V controlled substance.
Section 9.1 explicitly identifies Lyrica as a Schedule V controlled substance and discusses evaluation for misuse or abuse.
Gabapentin has a mechanism similar to pregabalin’s.
The label identifies gabapentin as a structurally related compound and says results involving related compounds suggest a role for alpha2-delta binding in pregabalin’s effects in animals. The broader claim of similar mechanisms is not established.
Unsupported Statements
Lyrica does not enhance athletic performance; no studies or athletic testing demonstrate ergogenic benefits; case reports do not link misuse to boosts in strength or speed.
The supplied label sections do not address athletic performance, ergogenic effects, or strength and speed outcomes.
Pregabalin reduces the release of glutamate, norepinephrine, and substance P, and calms overactive nerves.
The label describes reduced release of pro-nociceptive neurotransmitters in animal models but does not identify these specific neurotransmitters or characterize the effect as calming overactive nerves.
Pregabalin can cause fatigue, impair coordination, reduce motor skills, increase fall risk, or impair balance, decision-making, or proprioception.
The supplied text warns about dizziness and somnolence impairing certain tasks but does not identify these specific effects or consequences.
Pregabalin’s effects hinder physical exertion, reaction time, and endurance, and impair cognitive and physical function similarly to benzodiazepines.
The label warns about impairment of tasks such as driving or operating machinery. It does not make these athletic-function claims or compare impairment with benzodiazepines.
Somnolence occurs in up to 36% of users and dizziness in up to 45% of users.
The supplied section reports adult controlled-trial rates of 23% for somnolence and 30% for dizziness, and pediatric somnolence rates of 21% and 15% in specified seizure trials. It does not substantiate the stated “up to” figures across users.
Some athletes use pregabalin off-label for anxiety or minor recovery pain; pregabalin is banned in competition under WADA rules if it affects the CNS; beta-blockers are permitted by WADA in some cases.
The supplied label does not address athlete use, these uses, or WADA rules.
Case reports link pregabalin misuse to dependency and withdrawal.
The label discusses misuse and abuse monitoring but the supplied sections do not report these case findings or discuss withdrawal.
Taking 150–600 mg daily leads to peak sedation 1–2 hours after a dose, and pregabalin-related sedation lasts 6–12 hours.
The supplied sections do not establish this dose range or sedation timing and duration. The reported elimination half-life of about 6 hours does not establish how long sedation lasts.
Healthy-volunteer studies found worse fine motor tasks and 20–30% worse simulated driving performance.
The label warns that dizziness and somnolence may impair driving but does not describe these studies or results.
Ibuprofen is non-sedating; gabapentin may carry similar risks; topical lidocaine is an alternative; propranolol can be used for performance-related anxiety.
These drugs and comparisons are not addressed in the supplied label sections.
Lyrica requires a prescription.
The supplied sections do not state prescription requirements.
Lyrica is not approved for athletic use.
The label lists specific indications and does not include athletic use, but the supplied text does not explicitly state this regulatory conclusion.
Contradictions
Important Omissions
The neuropathic-pain indications should be stated with their label-defined scope: diabetic peripheral neuropathy, postherpetic neuralgia, and spinal cord injury.
Importance:
Moderate
The response should distinguish the label’s reported trial rates—30% for adult dizziness and 23% for adult somnolence—from unsupported broader maximum-rate claims.
Importance:
Moderate
The label specifically warns that dizziness and somnolence may impair driving or operating machinery.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Moderate
The response includes useful label-consistent warnings about dizziness and somnolence, but unsupported dose and sedation-duration claims and unsupported regulatory and performance assertions could mislead readers.

Recommendation
Poorly Aligned
Primary Issue
Numerous specific claims about athletic effects, WADA rules, studies, adverse-effect rates, and dose-related sedation are not supported by the supplied prescribing information.
Suggested Improvement
Restrict label-based claims to the listed indications, the specified alpha2-delta binding mechanism, and adverse effects and impairment warnings expressly reported in the supplied sections. Remove or clearly separate claims the label does not address.
