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 168 HR ethinyl estradiol 0.00146 MG/HR / norelgestromin 0.00625 MG/HR Transdermal System RxCUI 1534809

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

  1. Ingredients 3

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

    • Norelgestromin 326374
    • Ethinyl estradiol / norelgestromin 352377
  2. Brand names 2

    • Xulane 1536581
    • Zafemy 2531280
  3. Dose forms 12

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

  4. Clinical & branded drugs 6

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

Showing up to 8 concepts per family — 19 of 23 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.
This product uses publicly available data from the U.S. National Library of Medicine (NLM), National Institutes of Health, Department of Health and Human Services; NLM is not responsible for the product and does not endorse or recommend this or any other product.
