Special precautions to be taken by the person administering the veterinary medicinal product to animals
This product contains clenbuterol, a β-agonist. Take care to avoid skin contact. In case of skin contact wash affected area thoroughly. If irritation occurs/persists seek medical advice. Take care to avoid accidental eye contact. In the case of accidental eye contact, flush thoroughly with clean water and seek medical advice. When using do not eat, drink or smoke. Wash hands thoroughly after using the product.
Accidental self-injection may produce tachycardia and tremor. These effects may be reversed by the use of a non-selective beta-blocker. If accidental self-injection occurs seek medical advice immediately, avoiding driving if possible.
In clinical use, it has been noted that following intravenous administration to horses, cases of transient mild muscle tremor and sweating were observed. It is suggested that a ‘bolus’ effect may have occurred in these cases and caused transient peripheral vasodilation. This vasodilation is a feature exhibited by all beta-adrenergic drugs to a greater or lesser degree. These effects may be minimised by administering the product slowly.
If used during pregnancy, treatment must be discontinued at the expected time of delivery since uterine contractions may be abolished under its influence.
This product antagonises the effects of prostaglandin F2-alpha and oxytocin. This product is antagonised by beta-adrenergic blocking agents.
In case of accidental overdose, a β-blocker such as propanolol may be used.
