If your asthma symptoms are getting in the way, you may want to speak with a specialist—such as an allergist or pulmonologist—about your symptoms.

[H3]
Eosinophilic Asthma

[H3]
What are eosinophils?

Everyone has eosinophils (e-o-SIN-o-phils). They’re white blood cells, a normal part of your immune system. But for some people, too many can cause airway inflammation and lead to asthma attacks. If you have eosinophilic asthma, you are not alone. In fact, approximately 4 out of 5 adults with severe asthma may have eosinophilic asthma.* A simple blood test may help determine if you have eosinophilic asthma.
*A registry study considered ~84% of severe asthma patients most likely to have eosinophilic asthma based on several factors, including increased blood eosinophil levels (≥150 cells/μL).

[H3]
How do I know if I have eosinophilic asthma?

Your healthcare provider can review your current medications, history with asthma, and breathing tests, as well as measure your eosinophil count with a simple blood test to help determine if your asthma is eosinophilic asthma.

[H3]
About FASENRA

[H3]

Do not stop taking your other asthma medicines unless instructed to do so by your doctor.

Tell your healthcare provider or get emergency help right away if you have any of the following symptoms of an allergic reaction:
swelling of your face, mouth and tongue
breathing problems
fainting, dizziness, feeling lightheaded (low blood pressure)
rash

[H3]
What is FASENRA?

FASENRA is a prescription medicine used with other asthma medicines for the maintenance treatment of asthma in people 6 years and older whose asthma is not controlled with their current asthma medicines. FASENRA helps prevent asthma attacks (exacerbations) and may improve your breathing. Medicines such as FASENRA reduce blood eosinophils.* Eosinophils are a type of white blood cell that may contribute to your asthma.
FASENRA is not used to treat other problems caused by eosinophils and is not used to treat sudden breathing problems.
*The mechanism of action of FASENRA in asthma is not fully understood.

[H3]
What are the potential benefits of FASENRA?

When added to current asthma treatments, FASENRA has been clinically proven to help:

prevent asthma attacks
improve lung function better than standard asthma medicines alone

For people who rely on oral steroids, FASENRA can help:

lower oral steroid use*
some people completely stop using oral steroids†

Your results may vary.
Do not stop taking your other asthma medicines unless your healthcare provider tells you to.
*For people taking oral steroids daily.
† Complete reduction of daily steroid use was only in patients taking a daily dose of 12.5 mg or less.

[H3]
How is FASENRA administered?

The FASENRA prefilled syringe is an injection administered under the skin (subcutaneously) by a healthcare provider.
The FASENRA Pen is an injection administered under the skin (subcutaneously) by the patient, caregiver or healthcare provider. Do not try to inject the FASENRA Pen until you have been trained by your healthcare provider.

[H3]
How does FASENRA work?

FASENRA is designed to target and remove eosinophils, a key cause of asthma. The mechanism of action of FASENRA in asthma is not fully understood.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?

💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

FASENRA presents a high-substance clinical narrative that effectively neutralizes its marketing fluff with granular, FDA-audited trial data. The site is a rare example of a drug brand that prioritizes technical dosing protocols and quantified outcomes over generic emotional appeals. Its only significant failures are technical, specifically the lack of modern structured data to anchor its authority in the semantic web.

Implement MedicalWebPage and Organization schema to formally link the product to AstraZeneca and regulatory bodies. Add direct outbound links to ClinicalTrials.gov for each study referenced in the footnotes to provide a neutral verification path. Include Person schema for patient stories and named experts to remove the ‘unverifiable expert’ penalty. Update the patient treated count with a ‘current as of’ date to avoid credibility decay as the temporal anchor shifts beyond 2026.

The site is an exact match for the pharmaceutical and biotech industry, adhering to strict FDA-mandated structures such as the Important Safety Information (ISI) blocks and detailed indications for use. The language is technically precise, utilizing category-specific terminology like biologic, subcutaneous, and eosinophilic asthma.

“The score of 25 reflects a low BS environment. The primary penalties come from the Identity and Authority pillar (9 points) due to missing schema and the Trust and Proof pillar (5 points) for citing internal review counts without external verification. The site achieved a perfect 0 in Semantic Coherence, indicating absolute alignment between its marketing signals and clinical substance.”
