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.
Taking sertraline with abciximab can raise your chance of bleeding. Sertraline is an antidepressant, and one of its lesser-known effects is that it makes your platelets (the cells that help you form clots) a little less sticky. Abciximab is a strong blood thinner given in the hospital that also blocks platelets from clumping. Put together, they work in the same direction, so bruising or bleeding can happen more easily.
You might notice things like nosebleeds, easy bruising, or tiny red spots on the skin. This is manageable. Your care team knows how to watch for this, and they can keep a close eye on you while you are on both. Let them know right away if you notice unusual bleeding or bruising.
Effect: Additive antiplatelet/hemostatic impairment, increasing bleeding risk. Neither agent is a prodrug; this is a pharmacodynamic (not metabolic) interaction.
- Mechanism: Sertraline depletes platelet serotonin (via serotonin reuptake inhibition in platelets), impairing serotonin-mediated aggregation; abciximab is a GPIIb/IIIa inhibitor. Effects are additive on hemostasis.
- Direction/magnitude: Increased bleeding risk; magnitude not quantified.
- Onset: Unspecified.
- Evidence: Theoretical, supported by case-control/cohort data with SSRI plus antiplatelet combinations.
- Management: Monitor for epistaxis, ecchymosis, hematoma, petechiae, and overt hemorrhage; counsel patient. Given abciximab is acute/procedural, weigh bleeding risk in that setting.

An increased risk of bleeding
Interaction Deep Dive
Care should be taken when an SSRI is given together with an antiplatelet agent, since the combination may heighten the likelihood of bleeding events32. Using sertraline alongside an antiplatelet can amplify bleeding risk, a phenomenon possibly attributable to sertraline's influence on platelet serotonin release. Data 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 documented range from epistaxis, ecchymosis, hematoma, and petechiae to hemorrhages that are life-threatening. During concurrent administration of sertraline and an antiplatelet agent, observe the patient for indications of heightened bleeding and advise patients regarding the elevated bleeding risk 1.
Why it happens (mechanism)
Release of serotonin by platelets; additive effects on hemostasis
How to manage this interaction
Keep taking both exactly as prescribed unless your care team tells you otherwise. Abciximab is given in a hospital or procedure setting, so your team is already watching you closely.
- Your team may monitor you more closely for bleeding while you are on both.
- Watch for and report nosebleeds, easy bruising, tiny red skin spots (petechiae), blood in urine or stool, or any bleeding that will not stop.
- Tell your pharmacist or prescriber that you take sertraline, especially before any procedure.
- Do not start or stop either medication on your own; raise any concerns with your care team.
Management is individual — confirm any change with your pharmacist or prescriber.
Literature reports
3 reports — tap to read
a) A retrospective study involving patients older than 50 years diagnosed with acute myocardial infarction (N=27,058) found that using an SSRI together with any antiplatelet therapy significantly raised bleeding risk by 1.42-fold relative to aspirin alone. The combination of aspirin, clopidogrel, and an SSRI significantly elevated the risk by 2.35-fold versus aspirin alone and by 1.57-fold versus combined clopidogrel and aspirin therapy 2.
b) A systematic review and meta-analysis covering 22 observational studies found that SSRI use was linked to a significant 1.55-fold rise in the risk of upper gastrointestinal bleeding (UGIB). Using SSRIs together with antiplatelet drugs was linked to a 2.48-fold increase in UGIB risk (3 studies) 3.
c) Case reports and epidemiological studies (case-control and cohort designs) have shown a link between the use of agents that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. According to data from published observational studies, exposure to SSRIs, especially during the month before delivery, has been linked to a less than 2-fold increase in the risk of postpartum hemorrhage. Bleeding events associated with SSRIs and SNRIs have spanned from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages 1.
Common questions
Can I take Sertraline and Abciximab together?
Sertraline and abciximab both reduce platelet function, so combining them can increase bleeding risk; keep taking both as prescribed and report any unusual bleeding or bruising to your care team. Always confirm with your pharmacist or prescriber before making any change.
How serious is the Sertraline and Abciximab interaction?
It is rated major. Potentially serious — often needs a change or close monitoring.
How quickly could this interaction happen?
The documented onset is "unspecified". The timing of this interaction is not well characterized.
How is the Sertraline and Abciximab interaction managed?
Keep taking both exactly as prescribed unless your care team tells you otherwise. Abciximab is given in a hospital or procedure setting, so your team is already watching you closely. Your team may monitor you more closely for bleeding while you are on both. Watch for and report nosebleeds, easy bruising, tiny red skin spots (petechiae), blood in urine or stool, or any bleeding that will not stop.… Management is individual — always follow your own care team's guidance.
How strong is the evidence for this interaction?
The evidence is graded "theoretical". Predicted from the drugs' pharmacology; not yet confirmed in people.
