Insights
Serotonin reuptake inhibitors (SRIs) significantly increase bleeding risk, especially when combined with NSAIDs. Alternative antidepressants may be suitable for high-risk patients.
Area of Science:
- Pharmacology
- Clinical Medicine
- Patient Safety
Background:
- Serotonin reuptake inhibitors (SRIs) are widely prescribed antidepressants.
- Understanding the bleeding risk associated with SRIs is crucial for patient safety.
- Concurrent use of SRIs with other medications can modify bleeding risk.
Purpose of the Study:
- To review the risk of bleeding associated with serotonin reuptake inhibitors (SRIs).
- To provide evidence-based recommendations for managing patients at risk of bleeding while on SRI treatment.
- To identify factors that influence bleeding risk in SRI users.
Main Methods:
- A nonsystematic review of English-language MEDLINE articles published before June 2018.
- Searches included terms related to SRIs, antidepressants, hemorrhage, and stroke.
- Meta-analyses and individual studies were used to assess bleeding risk with specific SRIs and concomitant medications.
Main Results:
- SRIs increase bleeding risk by 1.16- to 2.36-fold.
- Concomitant use of SRIs and NSAIDs shows synergistic bleeding risk (OR 3.17-10.9).
- Acid-reducing agents may reduce gastrointestinal bleeds in users of NSAIDs and SRIs.
Conclusions:
- Clinicians must recognize the increased bleeding risk with SRIs, particularly when co-prescribed with NSAIDs.
- Patient education regarding concurrent NSAID and SRI use is essential.
- Alternative antidepressants with lower serotonin transporter affinity may be considered for high-risk individuals.
Objective:
This nonsystematic review describes risk of bleeding in treatment with serotonin reuptake inhibitors (SRIs) and provide recommendations for the management of patients at risk of bleeding.
Data Sources:
Articles were identified by English-language MEDLINE search published prior to June 2018 using the terms SRI, serotonin and noradrenaline reuptake inhibitors, OR antidepressive agents, AND hemorrhage OR stroke.
Study Selection And Data Extraction:
Meta-analyses were utilized to identify information regarding risk of bleeding with antidepressants. Individual studies were included if they had information regarding bleeding risk with specific SRIs, timing of risk, or risk with medications of interest.
Data Synthesis:
SRIs increase risk of bleeding by 1.16- to 2.36-fold. The risk is synergistic between SRIs and nonsteroidal anti-inflammatory drugs (NSAIDs; odds ratio [OR] range between studies 3.17-10.9). Acid-reducing medications may mitigate risk of gastrointestinal bleeds in chronic NSAIDs and SRI users (OR range between studies 0.98-1.1). Antidepressants with low or no affinity for the serotonin transporter, such as bupropion or mirtazapine, may be appropriate alternatives for patients at risk of bleeding. Relevance to Patient Care and Clinical Practice: This review includes data regarding bleeding risk for specific antidepressants, concomitant medications, and risk related to duration of SRI use. Considerations and evidence-based recommendations are provided for management of SRI users at high bleeding risk.
Conclusions:
Clinicians must be aware of the risk of bleeding with SRI use, especially for patients taking NSAIDs. Patient education is prudent for those prescribed NSAIDs and SRIs concurrently.
