Desvenlafaxine and Fluoxetine interaction

• Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents, but also when taken alone.

Serotonin Syndrome Serotonin-norepinephrine reuptake inhibitors (SNRIs) and selective-serotonin reuptake inhibitors (SSRIs), including PRISTIQ, can precipitate serotonin syndrome, a potentially life-threatening condition.

If concomitant use of PRISTIQ with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

Bleeding events related to SSRIs and SNRIs have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.

Drugs Having Clinically Important Interactions with PRISTIQ Table 8: Clinically Important Drug Interactions with PRISTIQ Monoamine Oxidase Inhibitors (MAOI) Clinical Impact The concomitant use of SSRIs and SNRIs including PRISTIQ with MAOIs increases the risk of serotonin syndrome.

If concomitant use of PROZAC with other serotonergic drugs is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases ( 5.2 )

If concomitant use of PROZAC with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

Bleeding reactions related to SNRIs and SSRIs use have ranged from ecchymoses, hematomas, epistaxis, and petechiae to life-threatening hemorrhages.

If serotonin syndrome occurs, consider discontinuation of PROZAC and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.2 )] .

The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, meperidine, methadone, buspirone, amphetamines, and St.
