No, not at all. Xanax R 0 3 9 is just a type of the Xanax medicine. Firstly, I used to take Xanax pills for my anxiety disorder. I purchased 0.5mg dose as my regular dosage wanted. But later when the doctor diagnosed me with panic disorder, he raised my dose and directed me to use 2mg Xanax every six hours.
Then I purchased yellow Xanax bars R 0 3 9. The medicine is a type of the popular Xanax bars that contain 2 mg dose. Xanax R 0 3 9 pills come in yellow color as rectangular bar-shaped tablets. They are not different from Xanax and work in the same way.
