Taking naproxen and quetiapine together may increase your risk of internal bleeding, particularly in the stomach or intestines. It can also increase the risk of bruising or bleeding from the gums. Additionally, both medications can affect your kidney function, and using them together might put extra strain on the kidneys.

Varför detta händer
Naproxen is an anti-inflammatory (NSAID) that can thin the blood slightly and irritate the stomach lining. Quetiapine, while an antipsychotic, can also interfere with how platelets (the cells that help your blood clot) work. When combined, these effects add up, making bleeding more likely. Both drugs also reduce blood flow to the kidneys.
Vad du bör göra
Tillbaka till innehållYou should use this combination with caution. Watch for signs of stomach irritation, such as indigestion, stomach pain, or dark, tarry stools. If you notice unusual bruising or bleeding that won't stop, contact your doctor. Your doctor may want to monitor your kidney function with occasional blood tests if you take these long-term.

Viktiga försiktighetsåtgärder
Tillbaka till innehållSuicidal thoughts and self-harm
Quetiapine can increase the risk of suicidal thoughts or self-harm, particularly in the first few weeks of treatment. Patients and carers should monitor for any sudden changes in mood, behaviour, or thoughts of hurting oneself.
Astma
Do not take naproxen if you have asthma that is sensitive to aspirin or other NSAIDs, as it can trigger a life-threatening asthma attack or severe breathing difficulties.
Stomach ulcers or bleeding
Naproxen can cause serious stomach ulcers and internal bleeding. This risk is higher if you have had ulcers before, are over 65, or take other blood-thinning medicines. Stop taking it and see a doctor immediately if you have black, tarry stools or vomit blood.
Pregnancy (third trimester)
Do not take naproxen if you are more than 20 weeks pregnant. It can cause serious kidney or heart problems in the unborn baby and may lead to complications during delivery.
Neuroleptic Malignant Syndrome (NMS)
Seek urgent medical attention if you develop a high fever, severe muscle stiffness, confusion, or sweating. This may be a sign of NMS, a rare but life-threatening reaction to quetiapine.
Heart disease (specifically heart rhythm disorders)
Quetiapine can affect your heart rhythm (QT prolongation). This risk is higher if you already have heart disease or take other medicines that affect the heart. Seek immediate medical help if you experience palpitations, fainting, or a racing heartbeat.
Drowsiness and impaired coordination
Quetiapine causes significant drowsiness and can affect your balance. Do not drive or operate machinery until you know how it affects you, and be careful to avoid falls, especially when getting up from a sitting or lying position.
Diabetes and blood sugar control
Quetiapine can cause a significant increase in blood sugar levels, even if you are not diabetic. If you have diabetes, you must monitor your blood sugar more closely as your medication dose may need adjusting.
Dementia in elderly patients
There is an increased risk of stroke and death when quetiapine used to treat dementia-related psychosis in elderly patients.
Varningar för mat och dryck
Tillbaka till innehållAlkohol
It is best to avoid or strictly limit alcohol while taking naproxen. Both alcohol and naproxen can irritate the lining of your stomach; combining them significantly increases your risk of developing stomach ulcers or internal bleeding.
It is best to avoid or strictly limit alcohol while taking quetiapine. Combining alcohol with this medicine can significantly increase drowsiness and dizziness, making you more likely to fall or have an accident. Both substances are processed by the liver, and combining them can put extra strain on your system.
Grapefruit juice
You should avoid drinking grapefruit juice or eating grapefruit while taking quetiapine. Grapefruit contains compounds that stop your body from breaking down the medicine properly. This can lead to dangerously high levels of quetiapine in your blood, increasing the risk of serious side effects.
Caffeine (Coffee, Tea, Energy Drinks)
Caffeine can interfere with how quetiapine works. It may reduce the effectiveness of the medicine or worsen certain side effects like restlessness. Try to keep your caffeine intake consistent and avoid consuming large amounts.
Food (General)
You should take naproxen with or just after a meal or a snack. This helps to protect your stomach lining and reduces the risk of indigestion or stomach pain.
Fettrika måltider
If you are taking the extended-release (XL) version of quetiapine, you should avoid taking it with a very heavy or high-fat meal. This can cause the medicine to be absorbed into your system too quickly (known as 'dose dumping'), which increases the risk of side effects. It is usually best to take it without food or with a light snack.
