Summary
The provided AI statements were not matched to the supplied FDA label text excerpts with sufficient specificity; therefore alignment cannot be verified. The label excerpt set is incomplete for key claims (e.g., dependence/withdrawal, specific benzodiazepine/alcohol statements, and extended-release/IR product-specific dosing), making multiple statements at high risk of being unsupported relative to the provided label text.
Category Scores
Accurate Statements
Taking hydrocodone more frequently than directed increases risk of overdose.
Label excerpt provided includes: "Following an acute overdosage, toxicity may result from hydrocodone or acetaminophen." and "Serious overdose with hydrocodone is characterized by respiratory depression … extreme somnolence …" (Section OVERDOSAGE).
Unsupported Statements
Hydrocodone dosing frequency depends on the specific product formulation (immediate-release vs extended-release) and the prescribed strength.
No immediate-release vs extended-release formulation-specific dosing guidance for hydrocodone/acetaminophen tablets was provided in the supplied label excerpts.
Different hydrocodone products are dosed on different schedules.
No cross-product schedule comparison was provided in the supplied label excerpts.
Immediate-release hydrocodone is typically taken more frequently (often every few hours).
No immediate-release-specific statement was provided for the hydrocodone bitartrate and acetaminophen tablets in the supplied excerpts.
Extended-release hydrocodone is designed to be taken less often (typically once or twice daily).
No extended-release hydrocodone dosing schedule statement was provided in the supplied label excerpts.
On prescription instructions, 'frequency' commonly appears as 'Take X tablets by mouth every Y hours.'
No such formatting or general prescription-writing convention was provided in the supplied label excerpts.
On prescription instructions, 'frequency' commonly appears as 'Take X tablets by mouth twice daily' or 'once daily.'
No such formatting or schedule statement was provided in the supplied label excerpts.
Taking hydrocodone more frequently than directed increases risk of serious side effects, including slowed or stopped breathing.
The label excerpt states hydrocodone may produce dose-related respiratory depression and includes respiratory depression in overdose descriptions, but the specific claim tying 'more frequently than directed' to 'slowed or stopped breathing' is not explicitly supported in the provided excerpts.
Taking hydrocodone more frequently than directed increases risk of serious side effects, including extreme sleepiness.
The label excerpt describes "extreme somnolence" in serious overdose with hydrocodone, but does not explicitly link this to taking more frequently than directed.
Taking hydrocodone more frequently than directed increases risk of serious side effects, including death.
No label excerpt provided states death as a direct consequence of taking more frequently than directed.
Taking hydrocodone more frequently than directed increases risk of dependence.
While the adverse reaction list includes "psychic dependence," the specific linkage to taking more frequently than directed was not provided in the excerpts.
Taking hydrocodone more frequently than directed increases risk of withdrawal if use is stopped suddenly.
The supplied excerpts do not include withdrawal or abrupt discontinuation guidance.
Hydrocodone is especially dangerous when combined with benzodiazepines (alprazolam, clonazepam, diazepam).
The drug interaction excerpt provided includes other CNS depressants (including alcohol) but does not specifically mention benzodiazepines or list the named agents.
Hydrocodone is especially dangerous when combined with other opioids.
No specific interaction warning for combining with other opioids beyond the general "other narcotic analgesics" additive CNS depression language was provided; the claim uses stronger wording ('especially dangerous') than the label excerpt.
Hydrocodone is especially dangerous when combined with alcohol.
The label excerpt mentions "other CNS depressants (including alcohol)" may exhibit additive CNS depression, but the provided excerpts do not support the phrase 'especially dangerous.'
The combination of hydrocodone with sedating medicines may change safety risk even at the prescribed frequency.
The label excerpt supports additive CNS depression with other CNS depressants and suggests reducing doses when combined, but it does not explicitly state 'even at the prescribed frequency' or 'change safety risk' in that phrasing.
Contradictions
Important Omissions
The AI list does not clearly state the label-supported dosing regimen for this product ("one or two tablets every four to six hours as needed" and "total daily dosage should not exceed 12 tablets").
Importance:
Moderate
The AI list does not reflect label-supported major acetaminophen warning specifics (e.g., not using more than one acetaminophen-containing product; seek care if exceeding 4000 mg/day).
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
High
Multiple statements are likely unsupported relative to the provided label excerpts (e.g., immediate-release vs extended-release schedules; named benzodiazepines; dependence/withdrawal; death; 'especially dangerous' phrasing). Unsupported or overconfident safety claims increase risk of misinforming prescribers/patients when compared only to the supplied label text.

Primary Issue
Many safety/interaction and formulation-specific claims are not supported by the provided FDA label excerpts, and some claims use stronger wording ('especially dangerous', 'death') than is explicitly present.
Suggested Improvement
Limit claims to the provided label language: use the label’s specific dosing instruction for this product (every 4–6 hours as needed; max 12 tablets/day), describe respiratory depression as dose-related and in overdose, and for interactions use the label’s general statement about additive CNS depression with other CNS depressants (including alcohol) without naming benzodiazepines or asserting 'especially dangerous/death/withdrawal' unless the provided label excerpts explicitly state them.
