Can I take Oxypro and Pregabalin together?

Drug interaction guide

Taking these two medicines together can significantly increase the risk of serious side effects. You may feel extremely drowsy, dizzy, or confused. Most importantly, this combination can slow down or stop your breathing (respiratory depression), which can be life-threatening. It can also lead to a deep sleep from which you cannot be woken (coma).

Why this happens

Both Oxypro (oxycodone) and pregabalin act as depressants on the central nervous system. When taken together, their effects 'stack' or add up. Oxycodone is an opioid painkiller that slows down the brain's control of breathing, and pregabalin enhances this effect, making it much more dangerous than taking either medicine alone.

What you should do

You must only take these two medicines together if they have been specifically prescribed by the same doctor who is aware you are taking both. Your doctor should start you on the lowest possible doses and monitor you closely.

Seek emergency medical help immediately if you or someone taking these medicines experiences:

  • Very slow or shallow breathing

  • Extreme sleepiness or inability to stay awake

  • Limp muscles or cold, clammy skin

  • Pinpoint pupils

  • A slow heartbeat or fainting
