Tenex and clonodine are hypertensives which are used off label for behavior issues in our kids.
the stimulant category of medications are used for adhd/add on this board. They can also be used for some other things but I dont think anyone on here is on them for anything else.
Mood stabilizers are used in one of the mood spectrum disorders which can run from pure mania all the way down to major depressive disorder but is most often used with bipolar disorder.
The SSRI's/SNRI's are the "newer" forms of anti-depressants such as prozac, paxil, zoloft, cymbalta, wellbutrin. You are on one of the older tricyclics such as amytripiline, noratripiline, trazadone. There is also a class called MAOI inhibitors that you really dont want to go to. Yucky stuff.
The anti-psychotics are mostly used on this board as an adjunct to either a mood stabilizer or an anti-depressant. Sometimes a psychiatrist will use an AP alone but in my opinion that is foolish and just a stop gap and not the end of the game.
Oh, there is another class that you are on and that is the benzodiazapams. Those are for anxiety and most doctors will only leave a person on them for a short period of time. That is the lorazapam you are on. I believe that is restoril if I am not mistaken. Restoril is used mostly for sleep and I have trialed it before but it doesnt work well for me. I have about a quarter of a bottle here.
Not knowing exactly what you need to know and what you have tried, I felt the best thing I could do is give you the medication info so you could have some working knowledge before you talked to the doctor.
