    As tapeworm infestation is unlikely to occur in horses before two months of age, treatment of foals below this age is not considered necessary.


    Do not use in foals under 2 weeks of age.

    Do not use in case of hypersensitivity to the active substances or to any of the excipients.


    Special precautions for use in animals

    Avermectins may not be well tolerated in all non target animals. Cases of intolerance are reported in dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and also in turtle and tortoises.

    Dogs and cats should not be allowed to ingest spilled paste or access to used syringes due to the potential for adverse effects related to ivermectin toxicity.  Also prevent them from eating poo from animals wormed with the product

    Adverse reactions (frequency and seriousness)

    Horses carrying heavy infection of Onchocerca microfilariae have experienced such reactions as swelling and itching after treatment. It is assumed that these reactions are the result of the destruction of large numbers of microfilariae.

    In case of very high levels of infestation, destruction of the parasites may cause a mild transient colic and loose faeces in the treated horse.

    Colic, diarrhea and anorexia have been reported in very rare occasions post treatment, in particular when there is heavy worm burden.

    In very rare occasions, allergic reactions such as hypersalivation, lingual oedema and urticaria, tachycardia, congested mucus membranes, and subcutaneous oedema have been reported following treatment with the product. A veterinarian should be consulted if these signs persist.

    Withdrawal period(s)
