I was treated at a local hospital for an overdose of xanax. The treatment at the hospital also was for hypertension. My family doctor had no priviledges at this out of county hospital so i was assigned a doctor who also was an attending physician at a local drug/mental health institution. This doctor changed my prescriptions from that of my family doctor (who had my hypertension at reasonable readings) to other precscriptions that included anti-psychotic medicines, stomach medicines, sleeping medicines and different hypertension medicines. I was at the hospital for four days to overcome the xanax overdose. My blood pressure readings never stabilized in the hospital on the new meds. I was then transported to a local drug/mental health hospital, which i was the only patient. At this institution my blood pressure never stabilized and was consistently at 200/120+ readings. The hospital was doing bedcheck on me, checking to see if i was in my bed and not hanging myself or whatever. I was given a bp check after the nurse found me awake and not feeling well. She took a reading on me and my blood pressure hit a high of 240/122 on the left arm. She contacted an ambulance for transport to a local hospital for treatment, telling me the institution had no way of helping this. While in transport to the hospital my blood pressure suddenly fell from 240/122 to 80/56 and i almost passed out, the ambulance crew stating i was bottoming out from all the drugs the institution had given me during the 4-12 shift of caretakers. I felt cold, extremely sick with dry heaves, sweating and completely scared. The hospital stabilized my condition. I was retransported back to the drug/mental health institution after 3+hrs treatment in the ER. When back at this institution my blood pressure hit a new high of 250 in the righ arm and neither nurse could read the bottom number. This was at appx. 430am with wakeup time at 6am. Feeling miserable after this ordeal i still got up, made my bed and sit in the day room awaiting my morning 'group meetings'. No one came to see me. I ate breakfast alone, being the single only patient and awaited daily activities which never came. At 10am that morning i was released from the institution. Bottom line: I overdosed myself at home with xanax and the institution overdosed me at their place with new medicines i had never taken. Is this common? Why didnt anyone contact my family doctor? What would have happened to me if the nurse at the drug/mental health unit had not checked my bed at midnight and I had started bottoming out in bed, alone? Was this a serious mistake on the institution for NOT listening to me and causing me to overdose? This was the single most freighting few moments of my entire life. Im 52, male.
