How long after taking tizanidine, can i take prescribed oxycodone?

You need to consult your Prescriber. These medications have risks with their benefits, and they can be more than additive when if taken together, however at times are prescribed that way, for specific needs of individual patients. If you are unclear, you should definitely follow up with your Doctor or Pharamcist.

Potentially, this could be a hazardous combination as side effects could well be additive. Risks of apnea at night in sleep, overdose potentials, addiction, tolerance, and habituation all come into play. You do not reveal why this combination is being planned, and I would remark, that these drugs are closely monitored in your home state.
