How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
An increased risk of bleeding
Interaction Deep Dive
Exercise caution when coadministering a SSRI and an antiplatelet agent as this may increase the risk of bleeding events12. Concomitant use of sertraline with an antiplatelet may potentiate the risk of bleeding. This may be due to the effect of sertraline on the release of serotonin by platelets. Case-control and cohort studies have shown that the combined use of selective serotonin and norepinephrine reuptake inhibitors (such as sertraline) and antiplatelet agents has been associated with an increased risk of bleeding. Bleeding events reported have included epistaxis, ecchymosis, hematoma, petechiae, and life-threatening hemorrhages. When sertraline and an antiplatelet agent are given concurrently, monitor patient for signs of increased bleeding and caution patients about the increased risk of bleeding 3.
Why it happens (mechanism)
Release of serotonin by platelets; additive effects on hemostasis
Literature reports
3 reports — tap to read
a) In a retrospective study of patients over 50 years of age with the diagnosis of acute myocardial infarction (N=27,058), SSRI use with any antiplatelet therapy significantly increased the risk of bleeding by 1.42-fold compared with aspirin use alone. Therapy with aspirin, clopidogrel, and an SSRI significantly increased risk by 2.35-fold compared with aspirin use alone and by 1.57-fold compared with clopidogrel and aspirin combination therapy 2.
b) In a systematic review and meta-analysis of 22 observational studies, SSRI use was associated with a significant 1.55 fold increase in risk of upper gastrointestinal bleeding (UGIB). Concomitant use of SSRIs and antiplatelet drugs was associated with a 2.48-fold increase in risk of UGIB (3 studies) 1.
c) Case reports and epidemiological studies (case-control and cohort studies) have demonstrated an association between the use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Based on data from published observational studies, exposure to SSRIs, particularly in the month before delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage. Bleeding events related to SSRIs and SNRIs have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages 3.
