Panic Attack Associated with Imatinib Mesylate?

Abstract

Objective:

To report a case of panic attacks in an individual on imatinib mesylate.

Case Summary:

A 34-year woman developed panic attacks a few days after starting imatinib. Investigations were negative, and the panic episodes were attributed to imatinib and possible interaction with paroxetine.

Discussion:

As of January 1, 2004, this is probably the first case reporting such an adverse event with imatinib. This adverse reaction was rated as possible based on a probability scale. It could have occurred due to a pharmacokinetic interaction between imatinib and paroxetine. Other possible hypotheses are discussed.

Conclusions:

Imatinib may be associated with panic attacks as a rare adverse event in predisposed individuals. Recognition of this phenomenon can be important in preventing or treating anxiety problems in patients taking imatinib.
