Yes, the injectable form has to be administered by a doctor or nurse. I could not find any info on the pill form of Midazolam but I found the syrup form. I think that this info can be applied as well to the pill form.
I still beleive that Midazolam is nothing to be experimenting with. A quote from rxlist:

VERSED Syrup should be used only in hospital or ambulatory care settings, including physicians' and dentists' offices, that are equipped to provide continuous monitoring of respiratory and cardiac function. VERSED Syrup must only be administered to patients if they will be monitored by direct visual observation by a health care professional. If VERSED Syrup will be administered in combination with other anesthetic drugs or drugs which depress the central nervous system, patients must be monitored by persons specifically trained in the use of these drugs and, in particular, in the management of respiratory effects of these drugs, including respiratory and cardiac resuscitation of patients in the age group being treated.
