Background: Selective Serotonin Reuptake Inhibitors (SSRIs) have been associated with upper gastrointestinal haemorrhage (UGIH) but the magnitude and characteristics of this reaction and possible interaction with concurrent Non-Steroidal Anti-Inflammatory Drug (NSAID) therapy are unknown.
Aim: To systematically evaluate risk of UGIH with SSRIs, including interaction with NSAIDs.
Methods: We searched PubMED, Science Citation Index, and trial registries for data on SSRIs, NSAIDs and UGIH. We evaluated spontaneous case reports from pharmacovigilance databases.
Results: Random effects meta-analysis of 4 observational studies involving 153,000 patients showed an odds ratio of 2.36 (95% CI: 1.44–3.85; p = 0.0006) for SSRI associated UGIH. The odds ratio increased to 6.33 (95% CI: 3.40–11.8); p < 0.00001) with concomitant NSAIDs.
In patients aged above 50 years age with no UGIH risk factors, the Number-Needed-to-Harm per year is 411 for SSRIs alone, and 106 with concomitant NSAIDs. Analysis of 101 spontaneous reports showed that UGIH occurred after a median of 25 weeks with SSRIs. Around 67% of these patients were on NSAIDs.
Conclusions: SSRI use, alone and in combination with NSAIDs, substantially increases the risk of UGIH. Clinicians should consider this when managing patients at risk of, or presenting with UGIH.
