ASERVO® EQUIHALER® (ciclesonide inhalation spray)

Managing Severe Equine Asthma

Severe equine asthma (SEA), also known as heaves, is a chronic, noninfectious inflammatory respiratory disease affecting approximately 12% of horses — 7 years of age or older. Clinical signs of SEA include a frequent cough and exercise intolerance, and it requires a veterinarian’s examination to diagnose.

Managing equine asthma is a two-step process: reducing dust and debris in the environment that can irritate and inflame the airway and lungs, and treating the inflammation with a glucocorticoid like ASERVO EQUIHALER.

Additional Product Information

Dosage & Administration

Severe equine asthma can only be diagnosed by a veterinarian. Therefore, ASERVO EQUIHALER can only be prescribed by a veterinarian. However, ASERVO EQUIHALER is made to be easily administered by an owner.  

The nostril adapter fits inside the horse’s left nostril, and the lever is used to release each puff of medication. The product is administered with the left hand, leaving the right hand free to hold the horse. ASERVO EQUIHALER contains enough medication to treat a horse for the labeled 10 days of administration (8 puffs twice a day for the first 5 days, then 12 puffs once a day for the next 
5 days). 

Before using the treatment, make sure to read the product leaflet inside the box carefully, and follow the instructions on how to pierce, prime and administer the product safely. The User Manual is also available digitally on AservoEquihaler.com/how-to-use. The scannable QR code on the box and in the user manual provides an instructional video.
