text: IV dose 1-1.5mg/kg or 3 to 5 x ED
  Paralysis occurs in one to two minutes.
  Clinical duration of action (time from drug administration to recovery of single twich to 25% of baseline) is 7-12 minutes.
  If IV access is unavailable, intramuscular administration 3-4mg/kg. Paralysis occurs at 4 minutes.
  Use of succinylcholine infusion or repeated bolus administration increase the risk of Phase II block and prolonged paralysis. Phase II block occurs after large doses (>4mg/kg). This occurs when the post-synaptic membrane action potential returns to baseline in spite of the presence of succinylcholine and causes continued activation of nicotinic acetylcholine receptors.
