This is an urgent request. Just need to know what the lethal dose of tizanidine is and how it interacts with oxycodone and hiv meds as well? Trying to help someone be safe.

Hi Michael - Sorry to hear about your friend. I checked MedlinePlus, and with a muscle relaxer such as Tizanidine, it would be very dangerous to take it with an opiate drug such as Oxycodone. Both medications can slow breathing to a dangerous level. May I ask what HIV medication they are currently taking? At the very least, taking a higher dose than what has been prescribed can cause unpleasant effects, such as:

- extreme fatigue / drowsiness
- mental fog / confusion
- dizziness
- show / shallow breathing
- slowed heartbeat
- fainting / loss of consciousness
