Accurate Statements
Promethazine should not be used in pediatric patients less than 2 years of age because of the potential for fatal respiratory depression.
WARNINGS (boxed warning): "PROMETHAZINE HYDROCHLORIDE SHOULD NOT BE USED IN PEDIATRIC PATIENTS LESS THAN 2 YEARS OF AGE BECAUSE OF THE POTENTIAL FOR FATAL RESPIRATORY DEPRESSION."; WARNINGS — Use in Pediatric Patients: "PROMETHAZINE PRODUCTS ARE CONTRAINDICATED FOR USE IN PEDIATRIC PATIENTS LESS THAN TWO YEARS OF AGE."
Postmarketing cases of respiratory depression (including fatalities) have been reported with promethazine use in pediatric patients <2 years.
WARNINGS (boxed warning): "POSTMARKETING CASES OF RESPIRATORY DEPRESSION, INCLUDING FATALITIES, HAVE BEEN REPORTED... IN PEDIATRIC PATIENTS LESS THAN 2 YEARS OF AGE."
Promethazine may lead to potentially fatal respiratory depression.
WARNINGS — Promethazine (Respiratory Depression): "Promethazine may lead to potentially fatal respiratory depression."
Caution should be exercised when administering promethazine to pediatric patients 2 years of age and older; lowest effective dose recommended and avoid concomitant administration of other respiratory depressants.
WARNINGS (boxed warning): "CAUTION SHOULD BE EXERCISED..." and "It is recommended that the lowest effective dose... be used... and concomitant administration of other drugs with respiratory depressant effects be avoided."
Respiratory depression and apnea are potentially fatal and are strongly associated with promethazine products in pediatric patients.
WARNINGS — Use in Pediatric Patients: "RESPIRATORY DEPRESSION AND APNEA, SOMETIMES ASSOCIATED WITH DEATH, ARE STRONGLY ASSOCIATED WITH PROMETHAZINE PRODUCTS..."; ADVERSE REACTIONS: "... respiratory depression (potentially fatal) and apnea (potentially fatal)."
People with breathing problems (compromised respiratory function) can be at higher risk with codeine.
WARNINGS — Promethazine (Respiratory Depression): "Use of promethazine in patients with compromised respiratory function (e.g., COPD, sleep apnea) should be avoided."

No supporting label text provided for self-medication guidance.
Suitability of promethazine with codeine depends on age, other medicines, and medical history.

Certain genetic factors affecting codeine metabolism can increase risk.
No genetic/pharmacogenomic codeine statements are included in the provided excerpts.
Clinicians often consider non-opioid options for cough relief depending on the cause of the cough.
No indications/therapy comparison text is included in the provided excerpts.
Non-opioid options for cough relief may be considered for viral illness, allergies, asthma, and reflux.
No label excerpt provided listing these alternative conditions/options.
The right cough treatment choice depends on symptoms and duration, not just what is “strongest.”
No label excerpt provided for cough-treatment selection criteria.
To obtain promethazine with codeine legally, an evaluation is typically needed for the cause of the cough and whether an opioid-containing product is appropriate.
No label excerpt provided for evaluation requirements or prescribing workflow.
To obtain promethazine with codeine legally, a prescription must be sent to a licensed pharmacy.
No label excerpt provided for how prescriptions are transmitted/dispensed.

AI Statement
People with breathing problems can be at higher risk with codeine.
Label Reference
WARNINGS — Promethazine (Respiratory Depression) addresses promethazine, not codeine.
Important Omissions
The label excerpt provides pediatric dosing tables (including maximum daily amounts for specific age ranges), but the evaluated response did not accurately present any label dosing details (dose and frequency by age, maximum daily volumes) for the product/formulation.
Importance:
Moderate
The label excerpt includes contraindications related to MAOI use for dextromethorphan and contraindication of antihistamines for lower respiratory tract symptoms (including asthma). The evaluated response did not mention these contraindications.

Safety Assessment
Potential Patient Risk:
Moderate
Some pediatric safety claims (promethazine <2 years fatal respiratory depression; apnea/respiratory depression risks; caution/avoid concomitant respiratory depressants) align with provided boxed warning/excerpts. However, many other claims attribute risks/medicinal effects to codeine and provide regulatory/clinical guidance not supported by the supplied label excerpts, which could mislead users about codeine-specific hazards and prescribing context.

Primary Issue
Large portion of claims are unsupported by the provided label excerpts, especially those attributing sedation/constipation/respiratory depression and genetic risk specifically to codeine and those making regulatory/clinical counseling statements.
Suggested Improvement
Limit claims to what is present in the provided label excerpts (e.g., promethazine boxed warning for pediatric <2 years, respiratory depression/apnea potentially fatal, caution in ≥2 years, avoid concomitant respiratory depressants, and the MAOI/asthma-related contraindication text shown). Avoid adding codeine-specific risks or general prescribing workflow/regulatory statements unless directly supported by the corresponding label sections.
