<s>[INST] Hi,  My VA doctor has prescribed Lorazepam 1 mg tablets for me for over three years for anxiety.  He also is giving me Bupropian HCL 100 mg for depression.  Both are for Post Tramatic Stress from combat in Vietnam.  My question is should I be taking these drugs for so long, especially the Lorazepam? [/INST] hello thanks for choosing healthcare magic.comIn Post traumatic stress disorder duration of treatment is 6 to 9 months. rest depends upon the flashabacks and anxiety symptoms. if patients is asymptomatic, medicine could be stopped by 9 months. In presence of anxiety symptoms medicine would go for longer time. Lorazepam should be stopped or take on SOS basis to avoid dependence.Thanks </s>
