Do SSRIs and Other Antidepressants Increase Bleeding Risk During Cosmetic Surgery?
⚠️ Contact your surgeon right away if you notice these after surgery
Rapid swelling, firmness, or unusual tightness on one side of your surgical site, skin that feels warm and looks bruised or purple, or pain that is getting worse rather than better can be signs of a hematoma. This can develop hours to days after surgery. Call your surgeon's office immediately or go to the emergency room if you cannot reach them, as a hematoma sometimes requires urgent drainage.
Short answer
Yes, SSRIs and similar antidepressants can modestly increase bleeding risk during surgery. The effect appears most meaningful for breast procedures, where the risk of a hematoma requiring a return to the operating room roughly doubles to quadruples, while evidence for facial cosmetic procedures is more reassuring. The risk is generally not life-threatening, but it is real enough that your surgeon and prescribing doctor should discuss it together before your procedure.
What the research shows
SSRIs and related antidepressants (sometimes called serotonergic antidepressants) work partly by limiting how much serotonin platelets can absorb. Because platelets rely on serotonin to clump together and form clots, this can make bleeding harder to stop. [1] [2]
A 2025 systematic review focused specifically on plastic surgery found that SSRI users undergoing breast procedures had a 2.7- to 4.1-fold higher chance of needing a return trip to the operating room for a hematoma (a pocket of blood under the skin), though the absolute rate remained below 5%. [1] For facial procedures such as face-lifts, one cohort study found no meaningful difference in hematoma rates between SSRI users and non-users (about 1.7% vs. 2.0%). [6] A broader 2014 review of 13 studies across many surgery types found odds ratios for abnormal bleeding or transfusion ranging from 1.2 to 4.1 among antidepressant users. [8]
Studies in orthopedic surgery consistently show increased blood transfusion needs for SSRI users: one meta-analysis in hip and knee replacement patients found an odds ratio of 1.78 for needing a transfusion [7], and a separate study in hip surgery patients found an odds ratio of 1.7. [3] An orthopedic cohort study found that nearly 1 in 5 SSRI users required significant transfusion compared to about 1 in 14 non-users. [4] Even in cardiac bypass surgery, a meta-analysis found a small but statistically significant increase in red blood cell transfusion (odds ratio 1.15), though no increase in mortality. [5]
What this means for you
If you take an SSRI or related antidepressant and are planning cosmetic surgery, you are likely not facing a dramatically higher overall risk, but the risk is real and varies by procedure. Breast surgeries appear to carry a more meaningful increase in hematoma risk than facial procedures. [1] [2]
Stopping an antidepressant before surgery is not automatically the right answer either. Abruptly stopping can cause discontinuation syndrome (flu-like symptoms, dizziness, mood swings) and may worsen depression. [2] Some clinicians consider switching temporarily to an antidepressant with less effect on serotonin, such as bupropion or mirtazapine, in high-bleeding-risk situations. [2] This decision should always be made jointly by your surgeon and your prescribing psychiatrist or primary care provider.
What to ask your surgeon
- Does my specific procedure (breast, face, etc.) carry a higher bleeding risk with SSRIs?
- Should my prescribing doctor and you communicate before I schedule surgery?
- Is temporarily adjusting or switching my antidepressant an option, and is it safe for my mental health?
- What signs of a hematoma should I watch for after surgery, and when should I call you immediately?
Caveats
Most of the available studies are retrospective cohorts, meaning researchers looked back at records rather than running controlled experiments. This limits how certain we can be about cause and effect. [1] [8] Studies in facial cosmetic surgery are especially small and underpowered. [1] [6] The evidence is strongest for orthopedic and breast procedures; data for other cosmetic operations such as liposuction or rhinoplasty are very limited. Individual factors like your specific medication, dose, other health conditions, and the surgeon's technique all matter too.
