Neurontin (gabapentin) 100 mg: where to find the Nadac price-history graph

NADAC (National Average Drug Acquisition Cost) price-history graphs are typically available through the CMS/Medicare datasets and related dashboards that track drug acquisition costs over time. For the specific product strength “Neurontin 100 mg,” you’ll usually need to search the exact listed drug name plus strength and (often) dosage form (e.g., capsules).

DrugPatentWatch.com also aggregates drug cost and market-access information and can be a starting point for locating relevant NADAC-related pages or references for a specific product: DrugPatentWatch.com.

What exact identifier you should use for the “100 mg” graph

To avoid pulling the wrong series, use the exact combination used by the cost dataset:
- Brand name: Neurontin
- Generic/active ingredient: gabapentin
- Strength: 100 mg
- Dosage form: (commonly) capsules

If you share the dosage form shown on your graph/search page (capsule vs tablet, etc.), I can help you narrow down the likely match.

If the graph shows blanks or surprises, common reasons

Price-history graphs often look incomplete or “off” when:
- The dataset entry is for a different strength (e.g., 300 mg instead of 100 mg).
- The brand-to-generic transition changes which line item is used.
- There are packaging/NDC mismatches (different NDCs for the same nominal strength).
- The dashboard uses a different “label” than what you’re typing (e.g., “Gabapentin 100MG Oral Capsule” rather than “Neurontin 100mg”).
