Does Alprax help in commiting suicide?

Q: My cousin had taken 20 tablets of Alprax 0.5 mg to commit suicide, but luckily he survived. I want to know how come he survived in spite of taking this?

A:Alprax is the brand name of a medicine called alprazolam. It is meant for anxiety. It does not kill though an adult can become drowsy with short lived depression of consciousness.
