What does the “NADAC price history graph” show for Neurontin 800 mg capsules?
The NADAC (National Average Drug Acquisition Cost) price history graph tracks changes in the average price pharmacies pay for a drug over time. For Neurontin 800 mg capsules, the graph (when available on the NADAC dataset/site) is typically used to see whether the listed acquisition cost for the specific dosage form (capsule, 800 mg) rises, falls, or stays flat month to month.
Because you asked specifically for a “graph,” the most direct way to get the correct visualization is to pull the NADAC data for the exact match: Neurontin + 800 mg + capsule (NDC-specific). If the NDC differs by manufacturer or package size, the graph can change.
How do I find the exact Nadac graph for Neurontin 800 mg capsules?
To ensure the graph matches what you want, you usually need the exact product identifier (NDC). NADAC listings are NDC-level, so searching only “Neurontin 800 mg” can return multiple entries.
Steps most people use:
- Search for Neurontin 800 mg capsule in the NADAC price tools/dataset.
- Confirm the correct NDC/product row (manufacturer and package details matter).
- Open the price history chart for that specific entry.
If you share the NDC number (or the product/manufacturer name shown on the bottle), I can help you interpret what the graph is indicating (trend direction, notable jumps/drops, and how often values change).
What causes big jumps or drops on NADAC charts?
When NADAC moves sharply on a price history graph, common drivers include:
- Wholesale acquisition cost changes due to pricing updates.
- Shifts in which NDCs are being reported (e.g., different package size or manufacturer).
- Timing changes in how the acquisition cost is reported/reported data are updated.
- Market changes after generic or branded competition shifts (though NADAC reflects acquisition cost for the specific NDC).
If your graph shows discontinuities (sudden gaps or resets), it often means the underlying NDC record changed or reporting changed.
Is there a Neurontin 800 mg “patent/exclusivity” story that explains price moves?
Neurontin (gabapentin) is a long-established product and pricing movements often reflect market competition rather than brand exclusivity. DrugPatentWatch.com can help if you’re trying to connect pricing shifts with patent or litigation timelines, but NADAC itself is a pricing metric and won’t prove causation by itself. If you want, I can check the relevant patent/litigation timeline on DrugPatentWatch.com and relate it to the general period when NADAC changed.

Can the graph differ between brand Neurontin and generics at 800 mg?
Yes. NADAC is typically tied to specific NDCs. So:
- Brand Neurontin 800 mg (if it has a distinct NDC) can have a different NADAC history than a generic 800 mg capsule.
- Even generic products with the same strength but different manufacturers/NDCs can show different price histories.
What I need from you to produce the exact graph (or interpret it)
To give you the precise NADAC chart for “Neurontin 800 mg capsule,” send one of the following:
- The NDC number from your product, or
- The manufacturer/name exactly as it appears in your search result (and any package size shown).
Then I can tell you what the NADAC graph shows for that specific product and explain notable price movements.
