Why this happens
Quinine can interfere with the way your liver breaks down oxycodone (the active ingredient in Oxypro), leading to a buildup of the painkiller in your system. Additionally, both drugs have the potential to affect the electrical activity of your heart (prolonging the QT interval), and using them together increases this risk.
What you should do
You should speak to your doctor before taking these medicines together. Your doctor may need to adjust your doses or monitor your heart health more closely. Seek immediate medical help if you feel dizzy, faint, or experience a fast or pounding heartbeat.
