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.
You're taking sertraline (an antidepressant) along with ticagrelor (Brilinta, which helps keep your blood from clotting). Both of these can make bleeding a little more likely. Sertraline affects how your platelets, the cells that help you clot, use a chemical called serotonin. Ticagrelor already works by making platelets less sticky. Put together, they can add up.
This means you might bruise more easily or notice nosebleeds. Rarely, bleeding can be more serious. The good news is your care team can manage this by keeping an eye on you. Keep taking both as prescribed and let your doctor or pharmacist know if you notice unusual bruising or bleeding.
Effect: Additive bleeding risk with concurrent sertraline (SSRI) and ticagrelor (P2Y12 inhibitor).
- Mechanism: Pharmacodynamic, not pharmacokinetic. SSRIs deplete platelet serotonin, impairing serotonin-mediated platelet aggregation; this adds to ticagrelor's antiplatelet effect on hemostasis.
- Direction: Increased antiplatelet/bleeding effect (neither is a prodrug relevant here).
- Evidence: Theoretical for this pair, though case-control/cohort data support increased bleeding with SSRI plus antiplatelet combinations.
- Onset: Unspecified.
- Management: Monitor for epistaxis, ecchymosis, hematoma, petechiae, and GI or major hemorrhage. Counsel patient on bleeding signs; dose/therapy individualized by the care team.

An increased risk of bleeding
Interaction Deep Dive
Caution is advised when a SSRI is given together with an antiplatelet agent, since the combination may raise the likelihood of bleeding events32. Taking sertraline alongside an antiplatelet may heighten bleeding risk, an effect that may stem from the way sertraline influences serotonin release by platelets. Findings from case-control and cohort studies have linked the joint use of selective serotonin and norepinephrine reuptake inhibitors (sertraline among them) with antiplatelet agents to a greater bleeding risk. The bleeding events that have been documented include epistaxis, ecchymosis, hematoma, petechiae, and hemorrhages that are life-threatening. If sertraline and an antiplatelet agent are used at the same time, watch the patient for indications of increased bleeding and warn patients about the elevated bleeding risk1.
Why it happens (mechanism)
Release of serotonin by platelets; additive effects on hemostasis
How to manage this interaction
Keep taking both medications as prescribed unless your doctor tells you otherwise. This combination is manageable with awareness and monitoring.
- Your care team may watch you more closely for signs of bleeding and may individualize your therapy if needed.
- Watch for and report nosebleeds, easy bruising, small red skin spots, blood in urine or stool, black stools, or bleeding that won't stop.
- Tell your pharmacist before adding NSAIDs (like ibuprofen), aspirin, or other blood thinners.
- Bring up any concerns about bruising or bleeding with your pharmacist or prescriber.
Management is individual — confirm any change with your pharmacist or prescriber.
Literature reports
3 reports — tap to read
a) A retrospective study examined patients older than 50 years who were diagnosed with acute myocardial infarction (N=27,058). In this population, the combination of an SSRI with any antiplatelet therapy raised the bleeding risk significantly, by 1.42-fold, relative to aspirin alone. The regimen of aspirin, clopidogrel, and an SSRI raised the risk significantly by 2.35-fold compared with aspirin alone, and by 1.57-fold compared with combined clopidogrel and aspirin therapy 2.
b) In a systematic review and meta-analysis encompassing 22 observational studies, the use of SSRIs was linked to a significant 1.55-fold rise in the risk of upper gastrointestinal bleeding (UGIB). The combined use of SSRIs and antiplatelet agents was linked to a 2.48-fold rise in UGIB risk (3 studies) 3.
c) Case reports along with epidemiological investigations (case-control and cohort studies) have shown a link between the use of agents that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Based on evidence from published observational studies, exposure to SSRIs, especially during the month prior to delivery, has been associated with a less than 2-fold increase in the risk of postpartum hemorrhage. Bleeding events associated with SSRIs and SNRIs have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages 1.
Common questions
Can I take Sertraline and Ticagrelor together?
