Flexineb: Innovative Equine Nebulizer

FlexinebRespiratory problems are frequent in performance horses. The most frequently occurring respiratory tract disorders are Recurrent Airway Obstruction (RAO) also known as heaves, Inflammatory Airway Disease (IAD) and Exercise-Induced Pulmonary Hemorrhage (EIPH). Typically, their treatment includes systemic administration of drugs using injections or the oral route; however, administration via aerosol devices is now considered to be a viable alternative way to treat respiratory issues. Flexineb™ is an easy-to-use veterinary medical device that produces a very fine mist of aerosolized drug, enabling this method of treatment for the horse.

Flexineb™ is a silent, efficient, portable equine nebulizer device that is simple to use, comfortable and affordable. It operates without the noise of loud compressors or the inconvenience of cumbersome hoses and electrical cords.

Flexineb™ utilizes proprietary technology and is extremely portable allowing in excess of three hours of operation before the lithium-ion battery needs recharging.



The Flexineb has proven itself useful when nebulizing antibiotics, bronchodilators, corticosteroids and mucolytics. Read the Flexineb™ Drugs Table for medications.

Cleaning and Disinfecting:

Cleaning is easy. Simply wash with warm, soapy water. Disinfecting is done by using cold sterilization methods. Read more about how to properly clean your Flexineb™ with the Medication Cup Cleaning Instructions.

Volume of Medication:

A standard 10 milliliter medication cup is included. A 20 milliliter extension is provided to facilitate volumes of up to 30 milliliters. No medication remains wasted in the cup after treatment.

Comfort and Tolerance:

Flexineb™ fits comfortably onto the horse’s nose as a result of the flexible material. An adjustable regulator allows full control of the exit valve, enabling the caregiver to bypass the valve for easy breathing or to facilitate inhalation of the medication deep into the lungs.


The transparent aerosol-holding chamber allows the user to see the aerosol mist being generated by the Flexineb™ system, in conjunction with the horse’s breathing emptying the chamber and receiving the fine particle aerosol.


System accessories include an AC power supply to charge the internal battery, a 20 milliliter extension cup, a cover plug for cleaning the med cup, a user manual, medication chart and a hard sided case.

The FLEXINEB controller is set to run for 18 minutes each time the POWER button is depressed.  After this time, if there is still medication to dispense or if you are using the extension cup, you will need to depress the POWER button again to resume nebulizing.

Although the Flexineb™ mask material is soft and flexible, the front aerosol chamber and battery controller are made of hard plastic. Therefore, caregivers should be mindful of the risk posed by the horse moving its head when the Flexineb™ is fitted on the animal.
