¿Puedo tomar Codeína y Paracetamol juntos?

Guía de interacción de medicamentos

Codeine and paracetamol are frequently used together to provide better pain relief than either medicine used alone. They do not have a negative interaction; instead, they work together in a helpful way. In fact, they are often sold combined in a single tablet (such as Co-codamol).

Generalmente se considera seguro tomar codeína y paracetamol together as these medicines work in different ways to stop pain.

Paracetamol works mainly in the central nervous system to reduce pain signals and lower fevers, while codeine is an opioid that changes how your brain and nervous system respond to pain.

Because they use different pathways, their effects are 'additive', meaning they provide a stronger combined effect.

How to take codeine and paracetamol together safely

  • Do not exceed the maximum dose for either medicine.

  • Check other cold or pain medicines to make sure they don’t already have paracetamol or codeine, as too much paracetamol can seriously damage your liver.

Precauciones importantes

Enfermedad hepática o consumo excesivo de alcohol

Taking paracetamol if you have liver problems or drink more than 14 units of alcohol per week significantly increases the risk of life-threatening liver damage, even at standard doses.

Asma o problemas respiratorios

Codeine can dangerously slow your breathing. You must not take it if you have severe asthma or chronic obstructive pulmonary disease (COPD), as it can lead to respiratory failure.

Opioid addiction or long-term use

Codeine is highly addictive. Using it for more than 3 days can lead to physical dependence and withdrawal symptoms; it should only be used for short-term pain relief.

Lactancia

No tome codeína mientras esté amamantando. Esta pasa a la leche materna y puede causar problemas respiratorios potencialmente mortales o somnolencia extrema en su bebé.

Advertencias sobre alimentos y bebidas

Alcohol

It is best to avoid or strictly limit alcohol when taking paracetamol and codeine. Combining alcohol with paracetamol increases the risk of serious liver damage. Combining alcohol with codeine can increase the sedative effects of the medicine, making you feel excessively sleepy, dizzy, or confused, and can lead to dangerous breathing difficulties.

Jugo de toronja

Grapefruit juice can interfere with how your body processes codeine. This may reduce the effectiveness of the pain relief or, in some people, increase the risk of side effects. It is best to avoid drinking large amounts of grapefruit juice while taking this medicine.

Cafeína (café, té, bebidas energéticas)

Be cautious with caffeine if you are taking 'co-codamol' (a combination of codeine and paracetamol) that already contains caffeine. Too much caffeine can cause tremors, a racing heart, and difficulty sleeping. If your medicine does not already contain caffeine, normal intake is usually fine.
