Hi there Its called something else over in the USA Retorin or something similar to this anyway it is a anti depressant anti anxiety anti insomnia medication with little or no side affects (apparently) i have no yet filled my script as i havent finished loving my valium and serepax. Well i say that but i too have begun to notice my tolerance level has begun blocking the effects of these two meds. I definatley will start taking Avanza though um i think if u contact member suzanne66 from memory she gave me a wonderful comment list regarding this med. im sorry i couldnt be anymore of help. But i can say that people were raving about this med.
