Drain it, flush it WELL. flush lines, If it was RV antifreeze, OK to drink, Radiator antifreeze, flush a lot more with city water, Maybe do the bleach sanitize thing, OK to use. Either case may have a bit of residual odor or taste, should not be any problem health wise. It will go away, but may take a while. Reason to use city water is for the chlorine used to purify. Bleach cycle does the same, bleach taste is better than antifreeze.
Most RV antifreeze is poisonous as it contains Ethanol, which is why the label has the poison symbol and the MSDS is some scary reading. It is also the cheap stuff that someone could afford to waste 5 gallons of. The non poisonous RV antifreeze is made from Glycol, and is safe for human consumption and actually tastes kinda fruity, but it is 5x more expensive and only available from RV dealers. Both are pink in color. I would assume worse case scenario to be safe.
See a write up I did on RV antifreeze with links to the MSDS for both Ethanol and Glycol versions. Also in many jurisdictions Ethanol based RV antifreeze is considered hazardous waste and has to be disposed of accordingly.
