Sometimes mydriasis may occur instead of administrating atropine to minimize the risk of ventricular miosis. With sufficient exposure, other symptoms of fibrillation. Administer atropine sulphate intravenously, or cholinesterase inhibition may occur as described in acute intramuscularly if iv injection is not possible. In moderately inhalation. severe poisoning administer atropine sulphate, 0.4-2.0 mg Chronic exposure: repeated every 15 minutes, until atropinization is achieved Prolonged exposure may cause effects as described in (tachycardia, flushing, dry mouth, mydriasis). Maintain acute exposure. Some compounds have caused toxic atropinization by repeated doses for 2-12 hours, or longer, effects on the crystalline lens, conjunctival thickening and depending on the severity of poisoning.
