500 mcg = 2.500 mL

  • At a concentration of 200 mcg/mL, you need 2.500 mL to deliver 500 mcg.
  • That is 0.5000 mg, or roughly 0.500 teaspoons (50 drops).
  • Always double-check the concentration printed on the actual vial or bottle before drawing up any dose.

Next stepFor injections or any high-risk medication, have a second clinician verify the calculation before administration.
