Warnings/Precautions

Concerns related to adverse effects:

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).

Disease-related concerns:

• Asthma: Use with caution in patients with a history of asthma.

• Cardiovascular disease: Use with caution in patients with cardiovascular disease (including hypertension and ischemic heart disease).

• Increased intraocular pressure: Use with caution in patients with increased intraocular pressure and/or narrow angle glaucoma.

• Prostatic hyperplasia/urinary obstruction: Use with caution in patients with prostatic hyperplasia and/or GU obstruction.

• Pyloroduodenal obstruction: Use with caution in patients with pyloroduodenal obstruction (including stenotic peptic ulcer).

• Thyroid dysfunction: Use with caution in patients with hyperthyroidism.

Special populations:

• Pediatric: Use is contraindicated in children <2 years of age; deaths have been reported in children <2 years of age who were taking carbinoxamine-containing products. Use may diminish mental alertness in children; in young children particularly, carbinoxamine-containing products may produce excitation.

Dosage form-specific issues:

• Sulfites: Some products may contain sodium metabisulfite, a sulfite that may cause allergic-type reactions including anaphylaxis and life-threatening or less severe asthmatic episodes, in susceptible patients.

Warnings: Additional Pediatric Considerations

Safety and efficacy for the use of cough and cold products in pediatric patients <4 years of age is limited; the AAP warns against the use of these products for respiratory illnesses in young children. Serious adverse effects including death have been reported. Many of these products contain multiple active ingredients, increasing the risk of accidental overdose when used with other products. Health care providers are reminded to ask caregivers about the use of OTC cough and cold products in order to avoid exposure to multiple medications containing the same ingredient (AAP 2018; CDC 2007; FDA 2017; FDA 2018).

Some dosage forms may contain propylene glycol; in neonates large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults including hyperosmolality, lactic acidosis, seizures and respiratory depression; use caution (AAP 1997; Shehab 2009).

Medication Safety Issues

High alert medication:

The Institute for Safe Medication Practices (ISMP) includes this medication among its list of drugs (pediatric liquid medications requiring measurement) which have a heightened risk of causing significant patient harm when used in error (High-Alert Medications in Community/Ambulatory Care Settings).

Older Adult: High-Risk Medication:

Beers Criteria: Carbinoxamine, a first-generation antihistamine, is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older (independent of diagnosis or condition) due to its highly anticholinergic properties including risk of confusion, dry mouth, constipation, and other anticholinergic effects and toxicities, reduced clearance with advanced age, and tolerance associated with use as a hypnotic. Exposure to concurrent anticholinergic drugs also increases risk of falls, delirium, and dementia; consider total anticholinergic burden when conducting medication reviews (Beers Criteria [AGS 2023]).

Pediatric patients: High-risk medication:

KIDs List: Carbinoxamine, when used in infants <1 year of age, is identified on the Key Potentially Inappropriate Drugs in Pediatrics (KIDs) list and should be avoided due to risk of death (strong recommendation; low quality of evidence) (PPA [Meyers 2020]).

Metabolism/Transport Effects

None known.
