Can I take Aspirin and Sertraline together?

Guide för läkemedelsinteraktioner

Taking aspirin and sertraline together increases your risk of bleeding, particularly in the stomach or gut. You may bruise more easily or notice that small cuts take longer to stop bleeding.

In more serious cases, it can lead to internal bleeding, which might show up as very dark or 'tar-like' stools, or vomiting blood.

Varför detta händer

Sertraline belongs to a group of antidepressants (SSRIs) that can lower the amount of serotonin in your blood platelets, which are the cells responsible for clotting.

Aspirin also thins the blood by preventing these platelets from sticking together. When used together, their effects combine, making it much harder for your blood to clot if a blood vessel is damaged.

  • If you must take both, watch out for signs of bleeding such as unusual bruising, nosebleeds, or dark poo (stools).

  • If you experience severe stomach pain or vomit blood (which may look like coffee grounds), seek medical help immediately.

  • Your doctor may suggest taking a 'stomach protector' medicine (such as omeprazole) to reduce the risk of ulcers.

Depression 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.

Increased bleeding risk

Taking aspirin and sertraline together significantly increases your risk of serious stomach bleeding. Seek urgent medical help if you vomit blood or pass black, tarry stools.

Astma

Do not take aspirin if you have a history of asthma triggered by aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), as it can cause a life-threatening asthma attack.

Low sodium (hyponatraemia)

Sertraline can cause a dangerous drop in blood sodium levels, particularly in the elderly. Seek medical advice if you experience persistent confusion, muscle weakness, or seizures.

Children and teenagers under 16

Never give aspirin to children or teenagers under 16 unless specifically prescribed by a doctor, due to the risk of Reye’s syndrome, a rare but fatal condition affecting the brain and liver.

Alkohol

Drinking alcohol while taking aspirin increases the risk of irritation and bleeding in your stomach and digestive tract. It is best to limit or avoid alcohol, especially if you take aspirin regularly.

It is best to avoid or strictly limit alcohol while taking sertraline. Combining alcohol with this medicine can increase side effects like drowsiness, dizziness, and impaired coordination. Additionally, both alcohol and sertraline can affect your mood, potentially making symptoms of depression or anxiety worse.

Caffeine

Sertraline can sometimes increase the effects of caffeine in your body. This may lead to feeling more jittery, anxious, or having difficulty sleeping. Monitor your caffeine intake to see how it affects you.

Grapefruit Juice

Grapefruit juice can increase the levels of sertraline in your blood, which may increase the risk of side effects. While the effect is usually modest, it is best to avoid drinking large amounts of grapefruit juice.
