Summary
Several statements about dizziness/somnolence and additive CNS/cognitive/motor impairment with alcohol are supported by the label’s ethanol interaction data and the general warnings for dizziness/somnolence. However, multiple claims go beyond the provided label excerpts—especially regarding alcohol’s effect on “effectiveness,” clinicians’ advice to “avoid/limit” alcohol, and specific urgency signs—so overall alignment is partial.
Category Scores
Accurate Statements
LYRICA can cause sedation and impaired coordination.
WARNINGS 5.5: LYRICA may cause dizziness and somnolence. DRUG INTERACTIONS 7: additive effects on cognitive and gross motor functioning when co-administered with ethanol (additive impairment).
Alcohol plus Lyrica can increase dizziness or drowsiness.
WARNINGS 5.5: dizziness and somnolence are adverse reactions with LYRICA. DRUG INTERACTIONS 7: additive effects on cognitive and gross motor functioning with ethanol.
Alcohol plus Lyrica can increase trouble with balance or thinking clearly.
DRUG INTERACTIONS 7: additive effects on cognitive and gross motor functioning with co-administration of LYRICA and ethanol.
Alcohol plus Lyrica can increase the risk of accidents such as falls and driving impairment.
Only partially supported: DRUG INTERACTIONS 7 supports additive impairment of cognitive and gross motor functioning with ethanol; label excerpts do not explicitly mention falls/driving.
Alcohol is a central nervous system depressant.
Not directly supported by provided label excerpts.
When alcohol and Lyrica are used together, their CNS depressant effects can add up and increase impairment risk even if the medicine still works as intended.
DRUG INTERACTIONS 7: no pharmacokinetic interactions seen; additive effects on cognitive and gross motor functioning when co-administered with ethanol.
The provided information does not indicate that alcohol makes Lyrica stop working.
DRUG INTERACTIONS 7: no pharmacokinetic interactions were seen with ethanol (supports lack of PK “cancellation,” though not explicitly about “effectiveness”).
Unsupported Statements
Alcohol does not typically cancel Lyrica’s effectiveness in the way a chemical interaction would.
Label excerpt 7 states no pharmacokinetic interactions with ethanol and additive cognitive/gross motor effects, but it does not explicitly address “cancelling effectiveness.”
Lyrica’s main effect comes from how pregabalin acts on the nervous system by changing the way nerve signals are processed.
Mechanism excerpt 12.1 describes binding to the alpha2-delta site; provided text does not support the specific phrasing about nerve signals.
Combining alcohol with Lyrica can raise the risk of problems because both can affect the brain and coordination.
Label excerpt supports additive effects on cognitive and gross motor functioning, but does not support “both can affect the brain and coordination” as stated.
Alcohol plus Lyrica can increase the risk of accidents such as falls and driving impairment.
Label excerpt does not mention falls or driving impairment explicitly; only cognitive/gross motor additive effects are described.
Alcohol plus Lyrica can increase sleepiness, dizziness, and impaired judgment.
Label supports dizziness and somnolence, and additive cognitive effects; the specific term “impaired judgment” is not in the provided excerpts.
Alcohol plus Lyrica can be dangerous for driving, operating machinery, or walking safely.
Label excerpt 7 does not mention driving/machinery/walking safety.
Most clinicians advise avoiding or limiting alcohol while taking Lyrica, or at least not drinking until you know how you personally react to the combination.
Not supported in the provided label excerpts.
If a person needs to drink while taking Lyrica, it is safest to talk with the prescriber first, especially if the person is also taking other sedating medicines.
Label excerpt provided does not include this prescriber/advice guidance. (It does discuss respiratory depression risk with co-administered CNS depressants, but not this specific “safest to talk” recommendation.)
Urgent medical help is needed if alcohol plus Lyrica causes severe sleepiness, confusion, fainting, trouble breathing, or inability to stay awake.
The provided label excerpts do not include this specific emergency threshold list or instruction.
Alcohol is a central nervous system depressant.
Not supported by provided label excerpts.

AI Statement
If alcohol is drunk while taking Lyrica, the main concern is increased side effects rather than loss of effectiveness.
Label Reference
DRUG INTERACTIONS 7 and WARNINGS 5.5 excerpts provided do not explicitly state that loss of effectiveness is not a concern; they only describe additive cognitive/gross motor effects and no pharmacokinetic interactions.
Important Omissions
The label excerpted interaction data specifically notes: no pharmacokinetic interactions with oxycodone/lorazepam/ethanol, additive effects on cognitive/gross motor functioning, and no clinically important effects on respiration. The response omits the respiration statement.
Importance:
Moderate
The response attributes risks to “CNS depressant effects can add up,” but does not mention the label’s specific framing that additive effects on cognitive/gross motor functioning were seen with ethanol (and that no clinically important respiratory effects were seen in the excerpt).
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Moderate
The response contains multiple accurate, label-consistent points about additive CNS/cognitive/gross motor impairment and LYRICA-related dizziness/somnolence, but also includes unsupported specifics (falls/driving safety, emergency symptom thresholds, and advice statements). These could mislead users about certainty and urgency relative to what the provided label excerpts actually state.

Primary Issue
Several claims are not supported by the provided LYRICA label excerpts, especially around “effectiveness cancellation,” clinician advice, driving/falls safety, and emergency thresholds; the label excerpt also notes no clinically important respiratory effects with ethanol, which is omitted.
Suggested Improvement
Limit statements to what the label excerpts support: LYRICA may cause dizziness/somnolence, and co-administration with ethanol shows additive effects on cognitive and gross motor functioning without pharmacokinetic interactions. Avoid unsupported guidance (clinician advice, driving/falls specificity) and avoid claiming specific emergency criteria not present in the excerpts.
