Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⏱️ Dosage and Administration ~1 min read ▾

DOSAGE AND ADMINISTRATION Carbinoxamine maleate is contraindicated in children younger than 2 years of age (see CONTRAINDICATIONS ). Carbinoxamine maleate should be taken on an empty stomach with water. DOSAGE SHOULD BE INDIVIDUALIZED ACCORDING TO THE NEEDS AND THE RESPONSE OF THE PATIENT.

Carbinoxamine maleate dosage should be based on the severity of the condition and the response of the patient. The drug is well tolerated in adults in doses as high as 24 mg daily, in divided doses, over prolonged periods. On the other hand, some patients respond to as little as 4 mg daily.

Clinical experience suggests the following dosage schedules: Tablets Usual Adult Dosage: 1 or 2 tablets (4 to 8 mg) 3 to 4 times daily Usual Child's Dosage: Six to eleven years – ½ to 1 tablet (2 to 4 mg) 3 to 4 times daily. Oral Solution Usual Adult Dosage: 1 or 2 teaspoonfuls (4 to 8 mg) 3 to 4 times daily Usual Child's Dosage (approximately 0.2 to 0.4 mg/kg/day, divided into 3 to 4 doses): Six to eleven years– ½ to 1 teaspoonful (2 to 4 mg) 3 to 4 times daily. Dosing for children 2 to 5 years of age should be based on weight whenever possible.

The usual dosage for children 2 to 5 years of age is approximately 0.2 to 0.4 mg/kg/day, divided into 3 to 4 daily doses. In general, this corresponds to a dose of ¼ to ½ teaspoonful (1 to 2 mg) 3 to 4 times daily.

⛔ Contraindications 42 words ▾

🔄 Drug Interactions 29 words ▾

Drug Interactions Monoamine oxidase inhibitors prolong and intensify the anticholinergic (drying) effects of antihistamines. Carbinoxamine maleate has additive effects with alcohol and other CNS depressants (hypnotics sedatives, tranquilizers, etc.).

🤰 Pregnancy 50 words ▾

Pregnancy Pregnancy Category C Animal reproductive studies have not been conducted with carbinoxamine maleate. It is also not known whether carbinoxamine maleate can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Carbinoxamine maleate should be given to a pregnant woman only if clearly needed.

🧒 Pediatric Use 52 words ▾

Pediatric Use Carbinoxamine maleate is contraindicated in children younger than 2 years of age (see CONTRAINDICATIONS ). Neonates have an increased susceptibility to anticholinergic side effects, such as CNS excitation, which may lead to convulsions. Carbinoxamine maleate may diminish mental alertness in children. In the young child, particularly, they may produce excitation.

🧓 Geriatric Use 72 words ▾

Geriatric Use Carbinoxamine maleate is more likely to cause dizziness, sedation, and hypotension in elderly patients (approximately 60 years or older). Sedating drugs may also cause confusion and over sedation in the elderly. Therefore, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic renal, or cardiac function, and of concomitant disease or other drug therapy.

🆘 Overdosage 134 words ▾

OVERDOSAGE Manifestations Antihistamine overdosage reactions may vary from central nervous system depression to stimulation. Stimulation is particularly likely in children. Atropine-like signs and symptoms - dry mouth; fixed, dilated pupils; flushing; and gastrointestinal symptoms may also occur.

Especially in infants and children, antihistamine overdosage may cause hallucinations, convulsions, or death. The oral LD 50 of carbinoxamine maleate in guinea pigs is 411 mg/kg. Treatment The treatment of overdosage with carbinoxamine maleate is essentially symptomatic and supportive.

Vital signs (including respiration, pulse, blood pressure, and temperature) and EKG should be monitored. Induction of vomiting is not recommended. Activated charcoal should be given and gastric lavage should be considered after ingestion of a potentially life-threatening amount of drug.

In the presence of severe anticholinergic effects, physostigmine may be useful. Vasopressors may be used to treat hypotension.

🧬 Clinical Pharmacology ~2 min read ▾

CLINICAL PHARMACOLOGY Mechanism of Actions Carbinoxamine maleate, an ethanolamine derivative, is an antihistamine with anticholinergic (drying) and sedative properties. Carbinoxamine appears to compete with histamine (type H1) for receptor sites on effector cells in the gastrointestinal tract, blood vessels and respiratory tract. Pharmacokinetics and Metabolism Carbinoxamine is well absorbed from the GI tract and appears to be extensively metabolized by the liver, and excreted in the urine as inactive metabolites within 24 hours.

Virtually no intact drug is extended in the urine. In a study comparing a controlled-release suspension and a solution of carbinoxamine, healthy volunteers were administered a single dose of 8 mg carbinoxamine. A time to maximum concentration (Tmax) was between 1.5 hours to 5 hours, a peak plasma concentration (Cmax) of about 24 ng/mL was observed and extent of exposure (AUC) was about 286 ng hr/mL.

The serum half-life is reported to be 10 to 20 hours. Drug/Food Interactions Carbinoxamine should not be used in patients with hypersensitivity to carbinoxamine. Carbinoxamine may increase the effects of other drugs such as barbiturates, TCAs, MAO inhibitors such as Phenelzine (Nardil), Tranylcypromine (Parnate), or Selegiline (Eldepryl), alcohol, other antihistamines, and CNS depressants.

Carbinoxamine can be taken with or without food. Cardiovascular Effects Cardiac effects, including prolongation of QT interval have not been adequately studied. Unlike other newer antihistamines, severe adverse cardiovascular effects are uncommon, and usually limited to over dosage situations.

Special Populations Pediatric Patients Carbinoxamine should not be used in newborn or premature infants. Neonates have an increased susceptibility to anticholinergic side effects, such as CNS excitation, which may lead to convulsions. Pregnancy and Lactation Safe use of carbinoxamine during pregnancy has not been established.

Therefore, carbinoxamine should not be used in women who are, or may become pregnant. Carbinoxamine is in the FDA pregnancy Category C. Women who are breast-feeding should avoid use of carbinoxamine, since small amounts appear to be distributed into breast milk.

Geriatric Patients Carbinoxamine is more likely to cause dizziness, sedation, and hypotension in elderly patients. The incidence of adverse reactions is higher in the elderly; therefore, a dosing adjustment may be necessary in this sub-population.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Carbinoxamine Maleate. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.
