Friend was prescribed hydrocodone bitrate 1mg/mlother ingredients other than hydrocodone, what to do?

Dont understand? As far as I know, the lowest hydrocodone dose in oral meds is 5 mg. If it was prescribed for an appropriate reason, he should take it as prescribed and not overuse it. If there are pills left over, he should discard them safely afterwards. I don't know what your question is. What do you have to do with a friend getting a prescription, and what exactly are you asking?
