Summary
Several safety-related claims include specific incidence rates and additional warnings that are not supported by the provided label excerpts. The label excerpts do support general infection risk and TB evaluation/avoid active TB, as well as hypersensitivity and infection monitoring language, but multiple detailed claims cannot be verified from the supplied text and a few appear inconsistent with the provided label scope (e.g., boxed warnings).
Category Scores
Accurate Statements
Cosentyx may increase the risk of infections.
Label 5.1: “COSENTYX may increase the risk of infections.”
Pre-treatment evaluation for tuberculosis is required (evaluate for active or latent TB before starting).
Label 5.3: “Evaluate patients for active or latent TB infection prior to initiating treatment with COSENTYX.”; Medication Guide excerpt: “Your healthcare provider should check you for TB before starting treatment with COSENTYX.”
Do not use Cosentyx in patients with active TB infection.
Label 5.3: “Avoid administration of COSENTYX to patients with active TB infection.”; Medication Guide excerpt: “Do not use COSENTYX if you have an active TB infection.”
Hypersensitivity reactions can occur and include serious allergic reactions such as anaphylaxis (with discontinuation instructions).
Label 5.2: “Serious hypersensitivity reactions including anaphylaxis, angioedema, and urticaria have been reported…”; includes discontinuation guidance.
Patients should be instructed to seek medical advice if signs/symptoms suggestive of infection occur, and serious infection requires close monitoring and discontinuation until resolution.
Label 5.1: “Instruct patients to seek medical advice if signs or symptoms suggestive of an infection occur. If a patient develops a serious infection, monitor…closely and discontinue COSENTYX until the infection resolves.”
Unsupported Statements
Cosentyx is an IL-17 inhibitor used for psoriasis, psoriatic arthritis, and ankylosing spondylitis.
The provided excerpts confirm IL-17 mechanism references in the context of infection/warnings, but the excerpt text supplied does not explicitly list approved indications (psoriasis, psoriatic arthritis, ankylosing spondylitis).
Cosentyx most often causes upper respiratory tract infections in 14–18% of patients.
Label 5.1 includes nasopharyngitis and upper respiratory tract infection rates (e.g., nasopharyngitis 11.4% vs 8.6%; URTI 2.5% vs 0.7%) but does not support a “most often…14–18%” statement for URTI specifically.
Cosentyx can cause diarrhea in up to 11% of patients.
No diarrhea incidence is present in the supplied label excerpts.
Cosentyx can cause nasopharyngitis (cold-like symptoms).
The supplied excerpts list nasopharyngitis as an example of common infections with incidence (11.4% vs 8.6%) but do not explicitly equate it to “cold-like symptoms.”
Injection site reactions (such as redness or itching) affect about 3–5% of patients treated with Cosentyx.
No injection site reaction incidence is present in the supplied label excerpts.
Cosentyx increases the risk of infections such as tuberculosis.
Label supports TB as an infection risk in general terms (Medication Guide) and requires TB evaluation, but the specific phrasing “increases the risk…such as tuberculosis” is not stated verbatim in the provided excerpts.
Cosentyx increases the risk of fungal infections.
Label 5.1 states candida infections and dose-dependent fungal infection risk trend, but it does not use the exact wording “increases the risk of fungal infections” (support exists indirectly, however specific fungal incidence claim beyond examples is not explicitly quantified in the provided excerpts).
Cosentyx can cause inflammatory bowel disease (Crohn's or ulcerative colitis) flares in 1–2% of patients.
No IBD/Crohn’s/ulcerative colitis flare incidence is present in the supplied label excerpts.
Cosentyx can cause hypersensitivity reactions such as anaphylaxis in less than 1% of patients.
Label 5.2 confirms anaphylaxis is reported, but the supplied excerpts do not provide a <1% incidence.
The FDA warns of potential suicidal thoughts with Cosentyx.
No suicidal thoughts/psychiatric warning text is present in the supplied excerpts.
The FDA warns of neutropenia with Cosentyx.
No neutropenia warning text is present in the supplied excerpts.
The FDA warns of new psoriasis onset with Cosentyx.
No warning about new psoriasis onset is present in the supplied excerpts.
In patients with psoriasis or psoriatic arthritis treated with Cosentyx, diarrhea and oral herpes are more common.
No diarrhea incidence and no oral herpes incidence are present in the supplied excerpts.
Uveitis (eye inflammation) occurs in 0.1–2% of patients treated with Cosentyx for psoriasis/psoriatic arthritis.
No uveitis incidence is present in the supplied excerpts.
In patients with ankylosing spondylitis treated with Cosentyx, candida infections occur in 1–3% of patients.
The supplied excerpts provide candida infection incidence in the context of PsO trials (1.2% vs 0.3%), but do not provide ankylosing spondylitis candida incidence of 1–3%.
Hypersensitivity occurs in less than 1% of patients treated with Cosentyx.
No hypersensitivity incidence rate is present in the supplied excerpts.
Symptoms of hypersensitivity to Cosentyx include rash, swelling, breathing difficulty, or low blood pressure.
The supplied excerpts mention serious hypersensitivity including anaphylaxis/angioedema/urticaria but do not list this symptom set.
Pre-treatment screening for latex allergy (syringe component) is required for Cosentyx.
No latex allergy screening requirement is present in the supplied excerpts.
Cosentyx is not approved for allergies.
The provided excerpts do not address approval/indications in relation to allergies.
Mild side effects with Cosentyx often resolve without stopping treatment.
No guidance on “mild side effects” resolution without stopping is present in the supplied excerpts.
Patients should be monitored for infections while using Cosentyx.
The provided excerpts instruct patients to seek medical advice for infection signs and provide monitoring/discontinuation for serious infection, but do not explicitly state a general “monitor for infections while using” sentence.

Important Omissions
Boxed warning status: The response asserts FDA warnings (e.g., suicidal thoughts) without the supplied label excerpt content confirming such warnings, and the provided excerpt set explicitly notes “Boxed Warnings: Not provided.”
Importance:
Moderate
Safety Assessment
Potential Patient Risk:
Medium
While general infection risk and TB evaluation/avoid active TB are supported, multiple safety claims with specific incidence rates and additional warnings (suicidal thoughts, neutropenia, new psoriasis onset, IBD flares, latex allergy screening, multiple rate claims) are not supported by the supplied label excerpts. This could lead to over/underestimation of risks and incorrect monitoring expectations based on unverified claims.

Primary Issue
Many detailed incidence-rate and warning claims are not supported by the provided FDA label excerpts, including specific percentages for infections/adverse events and assertions about FDA warnings not contained in the excerpts.
Suggested Improvement
Restrict claims to text directly supported by the supplied label excerpts (e.g., general infection risk; TB evaluation/avoid active TB; hypersensitivity includes anaphylaxis with discontinuation; immunization guidance for live vaccines). Remove or rephrase unsupported quantitative rates and warning categories unless the corresponding label sections are provided.
