Because antidepressants influence blood serotonin levels, their use may be associated with an increased risk of abnormal bleeding.
Why do antidepressants cause bleeding?
SSRIs inhibit the serotonin transporter, which is responsible for the uptake of serotonin into platelets. It could thus be predicted that SSRIs would deplete platelet serotonin, leading to a reduced ability to form clots and a subsequent increase in the risk of bleeding.
Can antidepressants cause internal bleeding?
If you’re on antidepressants, or are considering taking them, it’s worth examining some of the risks. That’s because selective serotonin reuptake inhibitors (SSRIs), one of the most widely prescribed classes of drugs to treat depression, have been found to carry a significantly increased risk of internal bleeding.
Does escitalopram make you bleed more?
SSRI antidepressants including escitalopram may increase the risk of bleeding events. Combined use of aspirin, nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen), warfarin, and other anti-coagulants may increase this risk.
How do SSRI increase bleeding risk?
SSRIs selectively inhibit presynaptic serotonin (5-HT) reuptake. Generally, it is supposed that SSRIs increase the risk of abnormal bleeding events by inhibiting the uptake of serotonin into platelets, thus leading to impairment in the platelet hemostatic response.
Does fluoxetine increase bleed risk?
Conclusion: In patients with depression, fluoxetine increases bleeding time whereas escitalopram has no effect on coagulation profile. However, both the drugs can be used safely for long-term treatment.
Does serotonin cause bleeding?
An increased risk of abnormal bleeding was strongly associated with the degree of serotonin reuptake inhibition. Case reports and observational studies have both shown an association between use of antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), and abnormal bleeding.
What are the signs of internal bleeding?
Signs and symptoms of internal bleeding
- weakness, usually on one side of your body.
- numbness, usually on one side of your body.
- tingling, especially in hands and feet.
- severe, sudden headache.

What are the signs of a GI bleed?
Vomiting blood, which might be red or might be dark brown and resemble coffee grounds in texture. Black, tarry stool. Rectal bleeding, usually in or with stool.
Symptoms of shock
- Drop in blood pressure.
- Not urinating or urinating infrequently, in small amounts.
- Rapid pulse.
Do antidepressants cause stomach problems?
Antidepressants can cause unpleasant side effects. Signs and symptoms such as nausea, weight gain or sleep problems can be common initially. For many people, these improve within weeks of starting an antidepressant.
Does Lexapro make you feel happy?
Escitalopram won’t change your personality or make you feel euphorically happy. It’ll simply help you feel like yourself again. Don’t expect to feel better overnight though. Some people feel worse during the first few weeks of treatment before they begin to feel better.
What are the bad side effects of Lexapro?
Side effects of Lexapro
- sleeping trouble.
- sexual problems, such as decreased sex drive and erectile dysfunction.
How long after stopping antidepressants before I feel normal again?
In studies on adults with moderate or severe depression, 40–60% report improvements within 6–8 weeks. Those who wish to come off antidepressants because they feel better should ideally wait for at least 6–9 months after complete symptom remission before stopping their medication.
Why do platelets release serotonin?
Serotonin is transported by platelets and released upon activation. This induces constriction of injured blood vessels and enhances platelet aggregation to minimize blood loss.
Do SSRIs thin your blood?
Platelets need the brain chemical serotonin to function properly. The most popular antidepressants on the market block the absorption of serotonin. The result, the researchers speculate, is that the drugs effectively act like blood thinners, increasing the risk of abnormal bleeding and hemorrhagic stroke.
Do SSRIs cause gastrointestinal bleeding?
There is evidence from observational studies to suggest that selective serotonin re-uptake inhibitors (SSRIs) increase the risk of developing gastrointestinal bleeding to about three times that in patients not using such drugs.
