Clinical overview

First-generation antihistamine

Brompheniramine has public medication-list entries in BAAS 2019, KABS 2020 open validation supplement, and CALS 2022 Table 4. These are 3 separate source versions, each with its own evidence and definitions.

How to read this: 0 means the source explicitly assigned zero. “Not listed” means the source did not provide a score for this medication. Scores from different scales are not averaged.

How to interpret the evidence

3 of 7 public source versions contain an explicit medication-list entry for brompheniramine.

The available rows for brompheniramine display the same numeric value. Agreement of the displayed numbers does not establish identical methods, clinical meaning or patient-level risk.

None of the public rows in this profile is an explicit zero. An unlisted source still supplies no value.

Class context — first-generation antihistamines

The 2023 AGS Beers Criteria identifies this class as highly anticholinergic in older adults and notes age-related clearance and cumulative anticholinergic exposure as relevant considerations. Drug-specific exceptions or route qualifications should be shown separately when present.

Older-adult medication context

AGS Beers context: classification and criteria

AGS Beers 2023 · Strong anticholinergicBeers: Avoid / generally avoid in older adults
  • Table 7: Strong-anticholinergic reference listing.
  • Table 2: General older-adult medication criterion.

Source-scale observations and geriatric criteria answer different questions. The Beers material does not alter any score above.

Adults 65 years and older; intended for ambulatory, acute, and institutional care except hospice/end-of-life settings.

Condition-specific and medication-combination contexts

Table 3: clinical conditions

Condition-specific contexts: delirium or high delirium risk, dementia or cognitive impairment, and history of falls or fractures. Applicability depends on the condition and the relevant source criterion.

Table 5: cumulative anticholinergic exposure

Concurrent use of more than one anticholinergic medication should be minimized because cumulative exposure increases geriatric safety concerns.

American Geriatrics Society 2023 updated AGS Beers Criteria — Tables 2, 3, 5 and 7; selected criterion context.

Potentially inappropriate does not mean absolutely contraindicated. Apply the criterion in clinical context and use shared decision-making.

What this page does not establish

  • No medication-list entry is available here from JARS 2025, Yamada-ABS 2023, Swe-ABS 2023, and GABS 2018. These gaps remain “Not listed”; no score is inferred from another source or from class membership.
  • No route inference unless present in the source label.
  • These source records do not estimate an individual’s probability of harm or establish whether to start, stop or change a medication. Ordinal source scores are not averaged into a UnifiedACB score.
