Summary
The provided FDA label excerpts do not contain the specific claims about cardiovascular effects (e.g., bradycardia/heart-rate changes, associated symptom list, risk factors like rhythm/conduction disease, dehydration/electrolyte problems, or specific other drugs slowing heart rate). The response therefore includes multiple unsupported statements relative to the supplied label text.
Category Scores
Accurate Statements
LYRICA may cause dizziness and somnolence; inform patients these may impair driving/operating machinery.
Label 5.5 Dizziness and Somnolence: 'LYRICA may cause dizziness and somnolence.'
Risk of PR interval prolongation is associated with LYRICA treatment (mean increase 3–6 msec at doses ≥300 mg/day).
Label 5.13 PR Interval Prolongation: 'LYRICA treatment associated with PR interval prolongation.'
Unsupported Statements
Lyrica (pregabalin) can affect the cardiovascular system in some people.
The supplied label excerpts mention PR interval prolongation but do not state general 'cardiovascular system' effects as a claim of cardiovascular-system impact in some people.
A slowed heart rate (bradycardia) is not one of the most common side effects of Lyrica.
The supplied excerpts do not identify or rank bradycardia as a common/most common adverse effect.
Heart-rate–related adverse effects associated with Lyrica have been reported in real-world use and in labeling/safety information.
The provided label excerpts do not mention heart-rate adverse effects or real-world reporting; only PR interval prolongation is explicitly described.
If Lyrica is causing heart-rate changes, symptoms may include dizziness, fainting (or feeling like you might), unusual fatigue, weakness, shortness of breath, or chest discomfort.
The supplied label excerpts do not list these symptom patterns as associated with 'heart-rate changes.'
Fainting, near-fainting, or chest pain associated with Lyrica needs urgent medical evaluation.
The supplied label excerpts do not provide instructions regarding urgent evaluation for fainting/near-fainting/chest pain.
Risk of heart-rate changes on Lyrica is higher if a person already has a heart rhythm problem or conduction disease.
No such risk stratification is described in the supplied label excerpts.
Risk of heart-rate changes on Lyrica is higher if a person takes other medicines that can slow heart rate or affect heart rhythm.
The supplied interactions section excerpt does not state additive effects related to slowing heart rate or heart rhythm.
Risk of heart-rate changes on Lyrica is higher if a person has other conditions that predispose to low heart rate, such as dehydration or electrolyte problems.
No such risk factor discussion appears in the supplied label excerpts.
Risk of heart-rate changes on Lyrica is higher if a person starts or increases the dose recently.
The supplied label excerpts do not link 'heart-rate changes' risk to initiation or dose increase timing.
Other medications that can slow heart rate include beta-blockers, some calcium channel blockers, and certain antiarrhythmics.
This is a general drug-class claim not supported by the supplied label excerpt.
Contradictions
Low
AI Statement
A slowed heart rate (bradycardia) is not one of the most common side effects of Lyrica.
Label Reference
No bradycardia prevalence ranking or commonality statement is provided in the supplied label excerpts.
Important Omissions
If discussing cardiovascular electrical effects, the label excerpt provided specifically supports PR interval prolongation; the response does not align its cardiovascular discussion to PR interval prolongation as the on-label cardiovascular finding.
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
High
The response asserts multiple heart-rate/bradycardia-related effects and urgent-evaluation guidance without support in the supplied label excerpts. While dizziness is supported by the label, the broader heart-rate-change symptom list and risk-factor assertions are unsupported relative to the provided FDA labeling text.

Recommendation
Not Aligned
Primary Issue
Major mismatch: multiple claims about bradycardia/heart-rate changes, associated symptoms, risk factors, and drug classes are not supported by the supplied FDA label excerpts. Only PR interval prolongation (and dizziness) are directly supported.
Suggested Improvement
Limit cardiovascular statements to what the supplied label supports (e.g., PR interval prolongation) and avoid claiming bradycardia, heart-rate-change symptom sets, urgent evaluation thresholds, or specific risk factors/drug classes unless those details are present in the provided labeling text.
