When horses work hard during exercise, the unsupported tissues overlying the nasal passages collapse, making it harder to breathe.

FLAIR® Equine Nasal Strips are drug-free, gently support the horse's nasal passages and are clinically proven to make breathing easier.

Developed by veterinarians, the proprietary adhesive and shape memory supports provide gentle support to the nasal passages to improve airflow to the lungs, reduce fatigue, conserve energy, quicken recovery and reduce lung bleeding

FLAIR Equine Nasal Strips

Lung bleeding, also known as Exercise Induced Pulmonary Hemorrhage (EIPH), is a silent injury that can go undetected by trainers and riders because it occurs deep within the lungs. EIPH occurs when fragile pulmonary blood vessels in the lungs rupture during exercise. This lung bleeding is best detected by lung washes or endoscopic examination. During the scoping, a long thin tube with a camera on the end is passed through the horse to view the upper airway and trachea. Blood in the lungs and lower airways has been shown to be an irritant that leads to further bleeding.

Numerous studies show that essentially all exercising horses experience some degree of EIPH during intensive exercise. Only 5% of horses show blood at the nostrils.

FLAIR® Strips are proven to reduce resistance to breathing so less stress is put on the pulmonary blood vessels, which helps them from rupturing. Even if a horse doesn’t compete with FLAIR Strips, using them in training will limit the damage occurring to the lungs so that the horse is in the best condition possible for competing.


It's common for many low and intermediate level bleeders to show no symptoms of lung bleeding; however symptoms include:

  • Poor Performance
  • Coughing
  • Extended Cooling-Out
  • Frequent Swallowing

There's potential for more damage if a horse: 

  • Gallops Fast and Often
  • Works on Extreme Foots (very hard or soft surfaces)
  • Carries More Weight (the more weight, the worse the bleeding)

Each incidence of EIPH contributes to scar tissue formation within the lungs and potentially future bleeding episodes. The lung damage from repeated episodes of EIPH can shorten a horse's competitive career.

Horses don't have to gallop to bleed. Research in Japan shows that horses only cantering at speeds of up to 20 mph (a very slow canter for a racehorse) all had damage to their lungs as a result of broken blood vessels. Some studies report that horses bleed even when doing mild exercise such as trotting on a treadmill.

Each time a horse does more than a slow canter, some blood vessels in the lung are broken. At first, this damage only affects a small area at the top back part of the lung; but, with repeated cantering, galloping and racing, the damage accumulates and affects more of the lung. The severity and frequency of bleeding observed by scoping after exercise or racing almost always increases with age.

Scar tissue forms in the lungs each time bleeding occurs. The blood vessels that break in the lung are almost always the blood vessels of the pulmonary circulation. When the vessels rupture, they may become blocked or not function normally. If the vessels are repaired, they may become stiff since scar tissue is not as flexible as normal healthy lung tissue. Damaged lung tissue, even if it is repaired, doesn’t function as well, leaving the horse’s lung capacity and function reduced.

The lung is a limiting factor for performance in horses; so, even small losses of lung function can have significant, unfavorable effects on performance and shorten a horse's competitive career.

Reducing bleeding not only helps a horse perform better in the short term, but may also help long term by reducing the possibility of inflammatory airway disease and chronic lung damage due to repeated bleeding episodes.
