What does rx o.d mean?

Answer by  Ryochan (214)

RX is generally used by doctors as an abbreviation of the word "Prescription", while O. D. in this case is probably "Overdose". So depending on the situation, RX OD is just saying someone overdosed on drugs one can get via prescription rather than via illegal means.

I'm guessing that it means "prescription overdose. " The common abbreviation for prescription is actually ℞, but it's often typed or written as Rx. Likewise, OD is a common abbreviation for overdose. ℞ is actually the abbreviated form of the Latin word "recipere," which is the imperative of the verb "to take. "
