Summary
Combining an SSRI with an NSAID substantially increases the risk of upper gastrointestinal bleeding compared with either drug alone. The risk is greater in older patients and those with prior ulcers or on anticoagulants.
What this interaction means in plain words
Naproxen and Sertraline can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Naproxen belongs to Musculoskeletal; Sertraline belongs to Central Nervous System.
Why it happens
SSRIs deplete platelet serotonin and impair aggregation, while naproxen inhibits platelet thromboxane and damages gastric mucosa, producing additive bleeding risk.
What to do
Avoid the combination where possible, or add a proton pump inhibitor for gastroprotection. Monitor for GI bleeding and anemia, and consider paracetamol as an alternative analgesic.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
