Can I take Oxycodone and Paracetamol together?

Guía de interacción de medicamentos

Oxycodone and paracetamol are often prescribed together to provide better pain relief than either medicine alone. However, taking them together increases the risk of side effects like constipation, nausea, and drowsiness. The most serious risk is that many oxycodone products already contain paracetamol (co-proxamol or similar brands); taking extra paracetamol on top of these can lead to a dangerous overdose and severe liver damage.

Por qué sucede esto

These drugs work in different ways to block pain (oxycodone works on the brain and central nervous system, while paracetamol works more on the peripheral nerves). Because they use different pathways, they have an 'additive' effect, meaning they boost each other's pain-killing power. They do not significantly change how the other is absorbed or broken down by the body.

It is usually safe to take these together if they have been prescribed that way by a doctor. However, you must check the packaging of your oxycodone carefully to see if it already contains paracetamol. Do not exceed the maximum daily dose of paracetamol (usually 4000mg or eight 500mg tablets in 24 hours). It is best to avoid or strictly limit alcohol when taking this combination, as both paracetamol and alcohol can strain the liver, and alcohol increases the sedative effects of oxycodone.

Opioid dependence/Addiction

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

Depresión respiratoria

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.

Liver damage (Overdose)

Taking more than the recommended dose of paracetamol can cause fatal liver failure. You must check all other medicines (like cold and flu remedies) to ensure they do not also contain paracetamol.

Alcohol

It is best to avoid or strictly limit alcohol when taking these medicines. Combining alcohol with paracetamol increases the risk of liver damage. Combining alcohol with oxycodone can cause dangerous levels of drowsiness, breathing difficulties, and a fatal overdose.

Jugo de toronja

Avoid drinking grapefruit juice or eating grapefruit while taking oxycodone. Grapefruit can increase the amount of oxycodone in your blood, which makes side effects like extreme sleepiness and slowed breathing more likely.
