Several case reports describe the development of 
serotonin syndrome, in patients taking fluoxetine, 
paroxetine or sertraline with 
tramadol. Another patient developed hallucinations when taking 
tramadol with 
paroxetine. 
 There would seem to be little reason for totally avoiding the concurrent use of the 
SSRIs and 
tramadol but it would clearly be prudent to use the combination cautiously and monitor the outcome closely. 
Tramadol should be used with caution with 
SSRIs because of the possible increased risk of seizures.
