🕸️ Concept Web — How Diphenhydramine hydrochloride 50 MG Oral Capsule Connects

One RxCUI never lives alone. Follow the path from the raw ingredient down to the exact strength-and-form concepts FDA products carry — every stop is a real RxNorm concept with its own identifier. Hover or focus any chip for what it means.
This page's concept Diphenhydramine hydrochloride 50 MG Oral Capsule RxCUI 1020477

Every web starts here: one RxCUI, one fixed meaning in the RxNorm vocabulary.

  1. Ingredients 2

    The active substance itself — no strength, form, or brand attached yet.

    • Diphenhydramine 3498
    • Diphenhydramine hydrochloride 1362
  2. Brand names 8

    The same medicine's trade names. A brand name alone says nothing about strength or form.

    • Banophen 215558
    • Benadryl 203457
    • Compoz 1085965
    • Nytol 1092413
    • Sleep-Eze 1092744
    • Sleepinal 219956
    • Unisom Sleep 1093099
    • Wal-Som Maximum Strength 1090453
  3. Dose forms 41

    The ingredient poured into a form — tablet, solution, cream — still without one fixed strength.

    • Diphenhydramine Oral Capsule 371891
    • Diphenhydramine hydrochloride Oral Capsule 2647158
    • Diphenhydramine Oral Product 1158449
    • Diphenhydramine Pill 1158450
    • Diphenhydramine hydrochloride Oral Product 2659104
    • Diphenhydramine hydrochloride Pill 2659100
    • Diphenhydramine Oral Capsule [Banophen] 366259
    • Diphenhydramine Oral Capsule [Benadryl] 366257
    • +33 more in this family
  4. Clinical & branded drugs 17

    Ingredient + strength + dose form. These are the concepts real FDA products actually carry.

Showing up to 8 concepts per family — 26 of 68 stored related concepts drawn.
These are official RxNorm vocabulary relationships — how concepts name and organize the same medicine. They do not establish therapeutic equivalence or substitutability: two concepts appearing in one web is never a statement that products can be swapped.

🔀 Generic ⇄ Brand Crosswalk

The same medicine has an unbranded (generic) identity and one or more brand-name identities — each with its own RxCUI. This is a naming relationship in RxNorm, not a statement that any two products are substitutable.

  • A shared RxCUI does not prove interchangeability. Products mapped to the same concept are not thereby equivalent or substitutable — equivalence is a separate, product-level determination.
  • Listing here does not establish approval or coverage. Appearing in this snapshot is a data observation, not an FDA approval status or a payer coverage decision.
  • Missing data never means zero. A silent dataset (no price, no billing code, no utilization) means no observation — not that the real-world value is zero.
  • Counts describe the mapping footprint. Product, package, and labeler counts are the FDA-listed mapping footprint in this snapshot — not sales, inventory, availability, or market share.
