Nervous system reaction symptoms and conditions

My 15 year old daughter was prescribed this medication for a sinus infection. By the 2nd day she had a headache and by that night she was having nightmares bad enough that she wanted me to watch her fall asleep. She is now paranoid, anxious, she has slept the entire day for the last 5 days and hasn't wanted to leave the house. I left the house and she called me on the phone very paranoid to the point she asked me not to hang up the phone and she kept asking how long until I come home. I was just a few blocks away and she kept telling me to hurry home. I put her in the car with us just to get out of the house then she said she felt sick and threw up. She hasn't held a full conversation in 5 days and says she feels like she's crazy. I called the on-call doctor's hospital and they surprised a doctor prescribed this to a teenager.

I have had moderate to severe pain in my hip due to joint deformity and subsequent deterioration and arthritis. I am unable to take even one dose of any NSAIDs as they cause stomach bleeding. Ten months ago a doctor prescribed Ultracet for me and it has provided tremendous pain relief for me. However, one of the side effects that I first noticed was it aggravated neck pain that I had from a couple of degenerated disks. I couldn't figure that out until a few months later when I read the Ultracet could cause muscle tightness. That explained that, and that finally subsided in the last few months. I had some of the side effects others described the first couple of days but then they subsided. I find that if I stick with just one tablet nstead of the two prescribed, I don't have all of the central nervous system reaction that some describe...nerve twitching, itching, sleeplessness and agitation, but if I take 2 at a time, I have all of the above. I always take one in the morning and usually don't have to take another the rest of the day unless I overdo. Sometimes I will need to take more doses but I take it knowing that I will be itching and agitated. I have had a couple of doctors since that have had bad experiences with Ultracet personally, and they always try to switch me to a narcotic. I have not had any decrease in effectiveness or increased need or dependency, but I also figure that if I only take my one in the morning on a normal basis, and only supplement as needed, I won't have problems with addiction.
