Calcium Chloride

  • pH: 5.5-7.5
  • Strength: 10ml (10%) contains 13.5mEq (272mg) Ca
  • Dilution: Preferably diluted with an equal volume of Water/NS to 5%
  • Potency: 3 times more potent than calcium gluconate
  • Precautions: IV use only

Ca Gluconate

  • pH: 6.0-8.2
  • Strength: 10ml (10%) contains 4.65mEq (93mg) Ca
  • Dilution: May be diluted in up to 1L NS
  • Potency: 1/3 potency of calcium chloride
  • Precautions: IM use permitted in adults only if IV cannot be accomplished

(Note: Ca preparations other than Ca chloride are often preferred except in cardiac resuscitation or verapamil toxicity.)
