Can I take Oxycodone and Quinine together?

Varför detta händer

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.

You should speak to your doctor before taking these two medicines together. If your doctor confirms you must take both, they may need to lower your dose of oxycodone. Seek medical help immediately if you feel unusually sleepy, have trouble breathing, or feel your heart racing or skipping a beat. Avoid driving or operating machinery while taking this combination.

Opioid dependence/Addiction

Oxycodone is highly addictive. Long-term use can lead to physical dependence and withdrawal symptoms if stopped suddenly.

Respiratory depression

Oxycodone can dangerously slow or stop your breathing, especially when first starting or if the dose is increased. This risk is much higher if taken with alcohol or other sedatives.

Heart rhythm disorders (e.g. Long QT syndrome)

Quinine can cause serious, potentially fatal heart rhythm changes; avoid if you have a history of heart rhythm problems.

Blood disorders (e.g. Thrombocytopenia)

Quinine can cause a sudden, severe drop in platelets which can lead to life-threatening bleeding; stop immediately if you notice unexplained bruising or bleeding.

Tinnitus (ringing in the ears) or hearing loss

Quinine can cause permanent hearing damage or worsen existing tinnitus. Stop taking the medicine immediately if you notice any changes to your hearing or ringing in your ears.

Alkohol

It is best to avoid or strictly limit alcohol when taking oxycodone. Combining alcohol with this medicine significantly increases the risk of dangerous side effects, such as severe drowsiness, breathing difficulties, and a potentially fatal overdose.

It is best to avoid or strictly limit alcohol while taking quinine. Both alcohol and quinine can affect your heart rhythm and cause dizziness; combining them may increase these risks.

Grapefruit juice

Avoid drinking grapefruit juice or eating grapefruit. Grapefruit can increase the levels of these medicines in your blood, making side effects more likely and potentially more severe.

Tonic water

Be aware that tonic water contains small amounts of quinine. While usually safe in small amounts, consuming large quantities of tonic water alongside quinine tablets could increase the risk of side effects like ringing in the ears or blurred vision.
