What the FDA labels say
From the Sumatriptan and naproxen (Sumatriptan and Naproxen Sodium) label · effective 2025-10-30
Serotonin Syndrome Serotonin syndrome may occur with sumatriptan and naproxen sodium tablets, particularly during coadministration with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and MAO inhibitors [see Contraindications (4) and Drug Interactions (7.1)] .
Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome Clinical Impact: Cases of serotonin syndrome have been reported during coadministration of triptans and SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.11)] .
Other factors that increase the risk for gastrointestinal bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status.
The onset of symptoms usually occurs within minutes to hours of receiving a new or a greater dose of a serotonergic medication.
Co-morbid conditions such as coagulation disorders or concomitant use of warfarin, other anticoagulants, antiplatelet agents (e.g., aspirin), serotonin reuptake inhibitors (SSRIs), and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk.
From the Vilazodone (VIIBRYD) label · effective 2023-10-01
Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone.
If concomitant use of VIIBRYD with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.
Drugs Having Clinically Important Interactions With VIIBRYD Table 4: Clinically Important Drug Interactions with VIIBRYD Concomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation Monoamine Oxidase Inhibitors (MAOIs) The concomitant use of MAOIs and serotonergic drugs including VIIBRYD increases the risk of serotonin syndrome.
If serotonin syndrome occurs, consider discontinuation of VIIBRYD and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )].
Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk ( 5.3 )
