Does tramadol cause seizures?

There's a nice evidence summary over at Emergency Medicine PharmD which concludes:

In summary, the risk of seizures in patients taking tramadol alone appears to be equal to patients not taking tramadol. However, certain risk factors may contribute to an increased risk of seizures in patients receiving tramadol. Co-morbid conditions predisposing patients to seizures, alcohol use and/or abuse, TCAs, SSRIs, MAOIs, other opiate use, other antidepressants and other drugs that may reduce the seizure threshold in conjunction with tramadol use have been associated with increased incidence of seizures. In addition, chronic users and abusers of tramadol seem to be at an increased risk of seizures.
