Illinois Department of Public Health: 5 things to know about psychotropics (including the right to informed consent)
The Illinois Dept. of Public Health states that consent forms for administering psychotropics must be signed by patients or someone with power of attorney. In general, consents must say what drug will be given, how much and how often. If a doctor wants to add a drug, the consent must be re-signed. The patient must be fully informed of risks.
