Summary
The AI claims largely do not match the provided FDA label excerpts for the actual product in scope (Promethazine DM: promethazine HCl + dextromethorphan). Several specific ingredient/mechanism/indication/sedation/controlled-substance statements are unsupported or contradicted by the provided label excerpts.
Category Scores
Accurate Statements
Promethazine hydrochloride is an antihistamine.
Supported by label clinical pharmacology excerpt: “Promethazine… H1 receptor blocking agent… antihistaminic action…”.
Unsupported Statements
The active ingredients in Actavis promethazine with codeine syrup are promethazine hydrochloride and codeine phosphate.
Label excerpt provided is for Promethazine DM (promethazine HCl + dextromethorphan hydrobromide) and lists those actives; codeine is not supported by the supplied label excerpts.
Codeine phosphate is a narcotic cough suppressant.
The provided label excerpts concern dextromethorphan as the antitussive; codeine phosphate is not supported by the supplied label excerpts.
Promethazine with codeine syrup is prescribed to relieve symptoms of the common cold and allergies, such as coughing, sneezing, runny nose, and itchy throat.
No supported FDA label indication text for common cold/allergies is included in the provided excerpts.
Promethazine with codeine syrup is used to alleviate nausea and vomiting.
The supplied excerpts do not provide an approved indication statement for nausea/vomiting.
Promethazine with codeine syrup is used as a sedative before medical procedures.
The supplied excerpts do not provide an indication/usage statement for pre-procedural sedation.
Promethazine works by blocking the effects of histamine.
While supported generally by the label excerpt as H1 receptor blocking (antihistaminic action), the statement is not tied to the correct product ingredients in the rest of the AI claims; however, on its own it is consistent with the provided mechanistic excerpt. (Marked unsupported because other codeine-based context indicates mismatch; see contradictions/overall.)
Codeine acts on the cough center in the brain to reduce the urge to cough.
The provided label clinical pharmacology excerpt describes dextromethorphan as an antitussive that centrally elevates the cough threshold; codeine mechanism is not supported.
Promethazine with codeine syrup is a prescription-only medication.
The provided excerpts do not state prescription-only status.
Promethazine with codeine syrup is not available for purchase over the counter due to the presence of codeine as a controlled substance.
The provided excerpts do not address OTC status or controlled-substance status.

High
AI Statement
The active ingredients in Actavis promethazine with codeine syrup are promethazine hydrochloride and codeine phosphate.
Label Reference
Provided label excerpts are for Promethazine DM containing “Dextromethorphan hydrobromide 15 mg” and “Promethazine hydrochloride 6.25 mg”; codeine is not listed in the supplied label context.
High
AI Statement
Codeine phosphate is a narcotic cough suppressant.
Label Reference
Provided label clinical pharmacology describes dextromethorphan as the antitussive (“antitussive agent… acts centrally…”); codeine is not described in the supplied label excerpts.
Important Omissions
Key contraindication/warning about promethazine pediatric use: contraindicated in children <2 years due to potential for fatal respiratory depression, and caution with pediatric use >=2 years.
Importance:
High
Avoid concomitant MAOI use with dextromethorphan (dextromethorphan-related contraindication/avoidance in CONTRAINDICATIONS).
Importance:
Moderate
Dose limits by age (pediatric and adult maximum daily volume) and the explicit contraindication by age in DOSAGE AND ADMINISTRATION.
Importance:
Moderate
Respiratory depression/apnea as potentially fatal adverse reactions and related monitoring/avoidance with other respiratory depressants.
Importance:
High
Safety Assessment
Potential Patient Risk:
High
Claims mismatch the provided labeled product (codeine vs dextromethorphan), and the response omits major boxed/warning-level pediatric respiratory depression contraindication information present in the supplied label excerpts.

Recommendation

Primary Issue
Multiple ingredient/product and mechanism/indication claims reference “promethazine with codeine” but the supplied label excerpts are for Promethazine DM (promethazine HCl + dextromethorphan). Major pediatric safety contraindication and respiratory depression warnings are omitted.
Suggested Improvement
Use the correct labeled product (Promethazine DM: promethazine HCl + dextromethorphan hydrobromide) and base ingredient/mechanism statements on the provided label excerpt; include the contraindication for children <2 years and respiratory depression warnings, plus avoid/contraindication statements relevant to the label excerpts.
