Special warnings

Special warnings for each target species

Special care should be taken when administering the veterinary medicinal product. To ensure an efficacious administration, the breath indicator in the chamber wall of the nostril adapter needs to be observed: when the horse inhales, the membrane of the breath indicator curves inwards. During exhalation, the membrane of the breath indicatior curves outwards. The spray should be released at the beginning of inhalation, i.e. when the breath indicator starts curving into the chamber. If the movement of the breath indicator cannot be observed, assure the correct positioning of the nostril adapter. If movement of the breath indicator is still not visible or the movement is too rapid, the product should not be administered. Efficacy of the product has not been established in horses with acute exacerbations (<14 days duration) of clinical signs.

listen

Special precautions for use in animals

Safety of the veterinary medicinal product has not been established in horses weighing less than 200 kg body weight, or in foals.

The prescribing veterinarian should assess if the horse has a temperament suitable for a safe and efficacious administration of the Aservo® EquiHaler® in agreement with good veterinary practice. Horses might not adapt to an easy and safe application of the Aservo® EquiHaler® within a couple of days. An alternative treatment should be considered if the horse does not adapt to the treatment with Aservo® EquiHaler®.

The onset of clinical improvement may take several days. The use of concomitant medication (such as bronchodilators) and environmental control may need to be considered in cases of severe clinical signs of respiratory obstruction, at the discretion of the attending veterinarian.

listen

Special precautions to be taken by the person administering the veterinary medicinal product to animals

Follow closely the instructions for handling and use of the Aservo® EquiHaler® as provided in the package leaflet section “Other Information”.

Acclimatising the horse with a training device, available from the marketing authorisation holder, prior to treatment start has shown to ease the administration of the veterinary medicinal product. Surveillance has shown cases where the horses were non-cooperative and therefore could not be treated according to the product information. In case a horse has a tendency towards defensive behavioural reactions, additional safety precautions could be considered (e.g. employ a second person to handle the horse).

Administration of the product should take place in well ventilated surroundings.

People with known hypersensitivity to ciclesonide or any of the excipients should avoid contact with the veterinary medicinal product.

Inhalative and intranasal corticosteroids may cause rhinitis, nasal discomfort, nosebleed, upper respiratory tract infection and headache. An aerosol filtering mask must be worn during handling and administration. This prevents inadvertent inhalation in case of unintended release of actuations outside the nostril or without the nostril adapter.

The product can cause irritation to the eyes due to its ethanol content. Avoid contact with eyes. In case of accidental eye contact, rinse with large quantities of water.

In case of experiencing an adverse reaction due to accidental inhalation, and in case of eye irritation, seek medical advice and show the package leaflet or the label to the physician.

These precautions should be followed by the person administering the product and persons in close proximity to the horse’s head during administration.

The safety of ciclesonide after inhalatory exposure has not been established in pregnant women. In animal studies ciclesonide has been shown to induce malformations in foetuses (cleft palate, skeletal malformations). Pregnant women should therefore not administer the product.

If the Aservo® EquiHaler®

is visually damaged it should not be used any more.

It is essential to keep the product out of reach for children.

listen

Pregnancy and lactation

The safety of the veterinary medicinal product has not been established during pregnancy or lactation.

Use only according to the benefit/risk assessment by the responsible veterinarian.

The product was shown to be teratogenic following oral administration after high doses in rabbits but not in rats.

listen

Interaction with other medicinal products and other forms of interaction

Concomitant use of clenbuterol in a field study in seven horses with severe equine asthma did not indicate any safety concerns.

listen

Overdose (symptoms, emergency procedures, antidotes)

After administration of the veterinary medicinal product at up to the 3-fold recommended dose for 3 times the recommended treatment duration no relevant clinical signs could be observed.

listen

Special precautions for the disposal of unused product or waste materials

Medicines should not be disposed via wastewater or household waste. Ask your veterinary surgeon how to dispose of medicines no longer required. These measures should help to protect the environment. The cartridge contains residual amount of the product at the end of the course of administration. This should be taken into account at disposal of the used veterinary medicinal product.

When the horse exhales, the membrane of the breath indicator curves outwards (picture 11b).

The optimum time for release is at the beginning of the horse ́s inspiration when the breath indicator B begins to curve inwards.

Please note: In order for the breath indicator to demonstrate when the horse inhales or exhales, the nostril adapter A must be correctly placed in the nostril and should fit tightly.

If the movement of the breath indicator cannot be observed, assure the correct positioning of the nostril adapter. If still no movement is visible, the product should not be administered.

Every actuation should be performed following the steps explained in pictures 6, 7, and 8.
