> The "accidental OD" scenario where an innocent patient quadruple-doses is realistic, and anticipated, and the shrewd consumer will avoid this.
I think we need to do more around accidental overdoses than suggest that everyone should be a "shrewd consumer".
All you need to do is read the warnings and follow the instructions. It is not difficult. It does require literacy and intelligence, but a caregiver or the patient themselves should not have difficulty with the terminating the drug type and the dosage limits. If they do have difficulty, just see a nurse or a PCP. It's not rocket science!
All these overdoses are happening because people do not read the warnings and they do not follow the instructions; and if they cannot understand the warnings and if they cannot follow the instructions, nor even consult a professional, then perhaps they deserve an overdose?
