3. Background
• In recent years, there has been an increase in the
length, detail, and complexity of prescription drug
labeling, making it harder for health care practitioners
to find specific information and to discern critical
information.
• Therefore, the FDA placed regulations governing the
content and format of labeling for prescription drug
products.
4. Importance of Drug Labeling
• A prescription drug product’s FDA-approved labeling is a
compilation of information about the product, which must be
approved by the FDA, based on the agency’s thorough analysis
of the new drug application (NDA).
• The labeling contains information necessary to consider the
product safe and effective for use.
• These labeling regulations make it easier for health care
practitioners to access, read, and use information in prescription
drug labeling.
• They also enhance the safe and effective use of prescription
drug products and reduce the number of adverse reactions
resulting from medication errors due to misunderstood or
incorrectly applied drug information.
6. General Labeling Provisions
Drug labels are generally expected to
contain the following:
• Drug name
• Name and place of business of manufacturer,
packer, or distributor.

9. General Labeling Provisions
(continued)
• Drugs containing sulfites
– This chemical is used to prevent oxidation of the active
drug ingredient and maintain drug potency.

bronchial asthma) in susceptible individuals.
• Prescription drugs containing sulfites:
– Statement must appear in “Warnings” section of labeling
• Epinephrine injection containing sulfites:
– Statement must appear in “Warnings” section of labeling
but should also include the following: “The presence of a
