What Kalydeco (ivacaftor) NDC codes are active or inactive with the FDA?
I can’t list specific “active” vs “inactive” FDA NDC codes for Kalydeco from the information provided here. NDC status changes by labeler/manufacturer, dosage form, package size, and whether a product was discontinued, so the only reliable way to get the current active/inactive set is to pull it from the FDA NDC Directory (or download the directory data) and filter for “Kalydeco” and “ivacaftor.”
How to check Kalydeco NDC codes (active vs inactive) on the FDA NDC Directory
Use the FDA’s NDC Directory search, then verify the status flags for each NDC returned:
1. Go to the FDA NDC Directory.
2. Search for “Kalydeco” (and also “ivacaftor” if results are incomplete).
3. Record each matching NDC plus its dosage form and package size.
4. For each match, note whether the listing is marked active or inactive in the directory.
If you tell me which exact Kalydeco strength(s) and dosage form(s) you care about (for example, 150 mg tablets vs 50 mg/75 mg granules depending on formulation) and the package size, I can help you narrow down what to pull from the directory.
Why “active vs inactive” NDCs can differ even for the same drug
Even for the same branded drug, the FDA directory can show different NDCs as active/inactive because of:
- Different package sizes and bottle/count configurations
- Different dosage strengths or formulations
- Changes in the manufacturer/labeler over time
- Temporary discontinuations and later re-availability
If you want, I can format the results for your use case
Reply with either:
- The Kalydeco strength(s) and dosage form(s) you need, or
- A link/export from the FDA NDC Directory results you’re looking at,
and I’ll help you organize the NDCs into active vs inactive and map them to the exact product descriptions.
