How can I search in Clinical Pharmacology using a National Drug Code (NDC)?

A National Drug Code (NDC) is a unique 10-digit, 3-segment number assigned to drug products regulated under Section 510 of the Federal Food, Drug, and Cosmetic Act (FDCA). The sections of this number identify the labeler/vendor, drug product, and package size.

• The first segment, the labeler code, is 4 or 5 digits and is assigned by the Food and Drug Administration. A labeler is any firm that manufacturers, repackages, or distributes a drug product.
• The second segment, the product code, is 3 or 4 digits and is assigned by the firm. It identifies a specific strength, dosage form, and formulation for a particular firm.
• The third segment, the package code, is 1 or 2 digits and is assigned by the firm. It identifies package forms and sizes.

On the product labeling, the NDC is provided in one of the following configurations: 4-4-2, 5-3-2, or 5-4-1.

How

1. From the 'Find by' drop-down menu (to the right of the Search field), select 'NDC'.

2. In the NDC text box, enter the 11-digit NDC number (with or without dashes). Please Note: If you do not enter the entire number, you will receive more search results.

• Clinical Pharmacology only accepts 11-digit NDC numbers. If the full 11-digit NDC number is not available, precede the appropriate segment with a leading zero followed by the NDC numbers as follows:

  •  For the 5-4-1 configuration, enter nnnnn-nnnn-0n.
  • For the 5-3-2 configuration, enter nnnnn-0nnn-nn.
  • For the 4-4-2 configuration, enter 0nnnn-nnnn-nn.
• Clinical Pharmacology also accepts just the 5-digit labeler code as well as the 9-digit labeler code/product code combination, which will display all products that include the labeler code only or labeler code/product code, respectively.

3. Click 'Search'.

4. Click on the drug name to view the detailed product information within the ‘How Supplied’ section of the drug monograph.

Please Note: Any drug product that has been taken off the market is noted with an off-market indicator (dagger symbol).
