no data available

4.3 Indication of immediate medical attention and special treatment needed, if necessary

/VET:/ Decontamination may not be practical due to the rapid absorption and onset of clinical signs. Heart rate and rhythm and blood pressure should be assessed, and an ECG obtained if needed. IV fluids should be given, along with atropine at 0.02 mg/kg, IV, if bradycardia is present. Diazepam (0.25-0.5 mg/kg, IV) can be given if CNS signs (eg, apprehension, shaking) are present. Serum electrolytes (ie, potassium, sodium, chloride) should be assessed and corrected as needed. Yohimbine, which is a specific a2-adrenergic antagonist, can also be used at 0.1 mg/kg, IV, and repeated in 2-3 hr if needed. /Imidazoline decongestants/
