Taking co-codamol and sertraline together can increase the risk of a rare but serious condition called serotonin syndrome. It can also make you feel more drowsy, dizzy, or confused than usual.
Additionally, sertraline may stop the codeine in co-codamol from working properly, meaning you might not get the pain relief you expect.

Cómo funcionan
Both drugs affect a chemical in the brain called serotonin; when levels get too high, it causes side effects.
Sertraline blocks a specific liver enzyme (CYP2D6) that the body needs to convert codeine into morphine. If this conversion doesn't happen, the pain-killing effect is lost.
How to take co-codamol and sertraline safely
Volver al contenidoSpeak to your doctor before taking these medicines.
If you must take both, be alert for signs of serotonin syndrome, such as shivering, diarrhoea, fever, sweating, or muscle stiffness.
If you find that co-codamol is not helping your pain, your doctor may suggest an alternative painkiller such as paracetamol (without codeine) or ibuprofen.

Precauciones importantes
Volver al contenidoDepression and anxiety disorders
You may experience an increase in suicidal thoughts or the urge to self-harm when first starting sertraline or changing the dose. This is more common in young adults under 25. Contact your doctor or go to hospital immediately if you notice any changes in your mood or behaviour.
Síndrome serotoninérgico
Taking these together increases the risk of serotonin syndrome, a potentially life-threatening condition. Seek immediate medical help if you experience agitation, hallucinations, rapid heart rate, or severe muscle twitching.
sobredosis de paracetamol
Co-codamol contains paracetamol. Do not take it with any other paracetamol-containing products (such as cold and flu remedies), as this can lead to fatal liver damage.
Adicción a los opioides y abstinencia
Co-codamol contains codeine, which can cause addiction if used for more than 3 days. Stopping suddenly after long-term use can cause withdrawal symptoms.
Dificultades respiratorias
No tome co-codamol si tiene asma severa o problemas respiratorios, ya que la codeína puede ralentizar peligrosamente su respiración.
Aumento del riesgo de sangrado
Sertraline increases your risk of serious bleeding, especially in the stomach. This risk is significantly higher if you also take aspirin, ibuprofen (NSAIDs), or blood-thinning medications such as warfarin.
Low sodium levels (hyponatremia)
Sertraline can cause a serious drop in blood sodium levels, especially in older patients or those taking diuretics. Seek medical help if you experience extreme confusion, weakness, or unsteady gait.
Advertencias sobre alimentos y bebidas
Volver al contenidoAlcohol
You must avoid drinking alcohol while taking co-codamol. Combining alcohol with codeine increases the risk of serious side effects, such as extreme sleepiness, breathing difficulties, and loss of consciousness. Additionally, both alcohol and paracetamol can affect the liver; combining them regularly increases the risk of liver damage.
It is best to avoid or strictly limit alcohol while taking sertraline. Combining alcohol with this medicine can increase side effects such as drowsiness, dizziness, and impaired coordination. It may also make your depression or anxiety symptoms worse.
Jugo de toronja
Grapefruit juice can interfere with how your body processes codeine, potentially making the medicine less effective or increasing the risk of side effects. It is best to avoid grapefruit juice while taking this medicine. Avoid drinking large amounts of grapefruit juice. Grapefruit can increase the levels of sertraline in your blood, which may increase the risk of side effects.
Cafeína
Some versions of co-codamol already contain caffeine. If you consume extra caffeine from coffee, tea, or energy drinks, it may make you feel shaky, anxious, or cause a racing heart.
Sertraline can sometimes cause nervousness or tremors. Consuming high amounts of caffeine may worsen these side effects or increase feelings of anxiety. It is advisable to monitor your caffeine intake.
