How widely Chlorpheniramine is used (Medicaid data)

A general measure of how commonly Chlorpheniramine is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.

Think of this as a proxy for how widely Chlorpheniramine is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.

How commonly is Chlorpheniramine prescribed? Of the 1,601 medications we measure, Chlorpheniramine ranks #878 by Medicaid prescriptions — more than 45% of them.

Source: Medicaid State Drug Utilization Data (CMS), aggregated by generic ingredient — summed across every NDC (all brands, strengths, salt forms and dosage forms) of Chlorpheniramine, and across all states and both fee-for-service and managed-care claims. A general popularity signal; it excludes Medicare, commercial insurance and cash prescriptions, so it is not total U.S. use. Based on the 9 of 119 listed Chlorpheniramine NDCs with Medicaid activity.

The same medicine may be made and packaged by different companies, so a single drug can have many directory entries. (It’s also why a refill can look different — a new shape, color, or box — even though it contains the same medication.)
