Great drug, used a lot in Sweden.
Its fairly lenient on side effects, the main advantage is that weight gain is not an issue. The main side affect is that the consumer may get extra-pyramidal effects and Parkinsons similar symtoms, ie cant sit still etc. It also has an alleged affect on white blood cells and the should be monitore although ive never witnessed this myself.
The parkinsons symptoms can be controlled with anti-parkinson medicine, "disipal" is one drug here, cant remember the name of the active substance though.
Its mainly used as an anti-phsychotic, i presume it would help concentration in school but only if the individual was being distracted by a phsychotic disorder or something likewise.
Long term anxiety, Buspiron seems to work well,
dixyrazin (esucos) is a similar but short term & fast working drug
