Human Toxicity

After injection,inhalation,or ingestion,the first symptoms to appear are muscle spasms.They appear very quickly after inhalation or injection within as few as five minutes and take somewhat longer to manifest after ingestion,typically approximately 15 minutes.With a high dose,the onset of respiratory failure and brain death can occur in 15 to 30 minutes.If a lower dose is ingested,other symptoms begin to develop,including seizures,cramping,stiffness,agitation and hypervigilance.Seizures caused by poisoning can start as early as 15 minutes after exposure and last 12–24 hours.They are often other adverse symptoms, including hyperthermia,rhabdomyolysis,myoglobinuric,kidney failure,metabolic acidosis,and respiratory acidosis.As poisoning progresses,tachycardia(rapid heart beat),hypertension(high blood pressure),tachypnea(rapid breathing), cyanosis(blue discoloration),diaphoresis(sweating),water-electrolyte imbalance, leukocytosis(high number of white blood cells),trismus(lockjaw),risus sardonicus (spasm of the facial muscles),and opisthotonus(dramatic spasm of the back muscles,causing arching of the back and neck)can occur.
