Why do wrong words in Patient Counseling Information matter?

Because this section is the one written to be said aloud. 21 CFR 201.57 says Patient Counseling Information must contain the information patients need to use the drug safely and effectively, and must reference any FDA-approved patient labeling. Our view: a correctly spelled wrong word here can travel into what a prescriber or pharmacist tells a patient, and into the patient labeling it points to. Spellcheck passes it.

This page is general information, not legal or regulatory advice.

What the section is for

21 CFR 201.57 says the section must contain information necessary for patients to use the drug safely and effectively. Any FDA-approved patient labeling must be referenced here, with its full text reprinted after this section or accompanying the labeling. Highlights must carry a set cross-reference to this section, naming the patient labeling or Medication Guide when there is one.

The FDA's guidance on this section says it should start with a reference to the FDA-approved patient labeling, and that its content is typically ordered by clinical significance, with the most important first. It says the section shouldn't be a simple list of risks or a repeat of whole paragraphs that appear elsewhere in the labeling, and that topics in it should typically also appear in any FDA-approved patient labeling.

Action words for patients

The guidance says the section should typically use active voice, such as instructions that begin Advise the patient, rather than passive voice. It says the information should cover when a patient should contact a health care provider, seek emergency help or discontinue the drug.

Our view: those are the words a patient acts on. A swapped verb, a dropped negation, or a condition word that names the wrong sign changes what the patient is told to do, and it reads as normal advice.

The section and its twin

Our view: this section and the patient labeling describe the same topics in different voices, one for clinicians and one for patients. That makes them easy to check against each other, and easy to let drift apart.

• Read each topic here against the matching passage in the Medication Guide or patient information.
• Check that the action, the sign to watch for and any timing are the same in both.
• For the patient documents themselves, see Medication Guide and patient labeling errors and patient medication information wording.

How to read the section for meaning

Practice advice:

• Read each instruction aloud as you would say it to a patient. If it sounds wrong spoken, it is probably wrong written.
• Underline each action verb and the sign or condition it depends on, then read them together.
• Check the cross-referenced section for each topic, such as Warnings and Precautions. See wrong words in Warnings and Precautions.

This is our reading of public guidance, not legal or regulatory advice.

What is Patient Counseling Information?

The prescription labeling section that, under 21 CFR 201.57, must contain the information patients need to use the drug safely and effectively and reference any FDA-approved patient labeling.

Why do wrong words here matter?

In our view, because the section is written to be passed on, so a wrong word can carry into what patients are told and into the patient labeling.

Does it have to match the Medication Guide?

The FDA's guidance says topics in this section should typically also appear in the FDA-approved patient labeling. Practice advice: read the two against each other.

How do I check it?

Practice advice: read each instruction aloud as you would say it to a patient, then check the action and the sign it depends on against the patient labeling.
