Question

a pharmacy technician is filling a prescription for fluoxetine 10 mg capsules with an ndc number of 50111-0647-03. the technician pulls a stock bottle with an ndc number of 50111-0647-01. the technician should recognize which of the following?

• the manufacturer is incorrect.
• the strength is incorrect.
• the package size is incorrect.
• the dosage form is incorrect.

Explanation:

Analyze the NDC structure

Using the Drug Nomenclature knowledge point
An NDC (National Drug Code) number is a unique 10-digit, 3-segment identifier:

• Segment 1 (Labeler/Manufacturer): 50111
• Segment 2 (Product code - strength/dosage form): 0647
• Segment 3 (Package code - package size): 03 vs 01

Compare the NDC numbers

Using the Drug Nomenclature knowledge point

• Prescription NDC: 50111-0647-03
• Stock bottle NDC: 50111-0647-01
• The first segment (50111) matches, meaning the manufacturer is correct.
• The second segment (0647) matches, meaning the drug strength and dosage form are correct.
• The third segment differs (03 vs 01), indicating a difference in package size.

Answer:

• The manufacturer is incorrect.
• The strength is incorrect.
• The package size is incorrect. (Correct answer)
• The dosage form is incorrect.
