Is That Cough a Sign of Severe Eosinophilic Asthma? Experts Reveal New Treatment
A lingering cough. Tight chest. Shortness of breath. For most people, it might just seem like allergies or a mild cold. But for others—it could be something more serious: severe eosinophilic asthma. But here’s the good news: In 2025, game-changing new treatments are making a big impact—and experts say they could completely shift how eosinophilic asthma is managed.

🚨 The Symptoms Are Subtle—At First
A persistent cough that won’t go away. Breathlessness that worsens at night. Frequent use of rescue inhalers. If this sounds familiar—and traditional asthma meds aren't helping—it might be time to consider eosinophilic asthma.
What makes it different? It often resists typical inhaler treatments and worsens even with good asthma control plans.
đź’‰ The Breakthrough: Biologic Therapies
The biggest advance in 2025 is in biologic injections—targeted treatments that go straight to the source of the inflammation.
Top options include:
- Nucala (mepolizumab)
- Fasenra (benralizumab)
- Dupixent (dupilumab)
These biologics reduce eosinophil levels in the blood, which means fewer flare-ups, less coughing, and less reliance on steroids.
Many patients are seeing life-changing results in just a few weeks.
👩‍⚕️ Who Should Consider These Treatments?
Doctors now recommend biologics for people who:
- Have two or more asthma attacks per year
- Are using oral steroids frequently
- Have elevated eosinophil levels in blood tests
If you're constantly coughing or waking up at night wheezing—even when using controller meds—you may be a candidate.
đź§Ş Testing Makes It Clear
Simple blood tests now allow doctors to identify eosinophilic asthma quickly. In 2025, more clinics are routinely screening asthma patients with high inflammation markers—and tailoring treatments on the spot.
