I just have a question regarding analgesics. A contraindication for acetaminophen is use of it within the last 4 hours. Lets say for an adult patient they took 500mg prior to EMS arrival, would it then be okay to administer an additional 500mg to complete the full max single dose of 1000mg or should you withhold the acetaminophen in honour of the contraindication?


In this described situation, medical council supports paramedics providing the additional 500 mg dose. Please ensure rationale is provided for this administered dose within the ACR, as this will likely result in an audit given the dose discrepancy.  Documentation of rationale will ensure the auditor is aware of the reason for the lower dose of acetaminophen that has been administered and will result in one less email in your inbox!
