Abstract:
The authors report the case of a patient arrived in psychiatric ambulatory with a panic-like symptomatology. The patient refers that the symptomatology appeared after taking sibutramine. She took it with the intent to lose weight. After the disturbance beginning, the patient interrupted the sibutramine treatment but the psychiatric symptomatology didn't regress completely. It is supposed, in the light of this new evidence and in conformity of DSM-IV criteria, the diagnosis of substance-induced anxiety disorder with panic attack. Paroxetine and alprazolam were administered to the patient, with the resolution of the anxious symptoms. After eight months the treatment was suspended, since the patient referred to be pregnant; in any case, during the pregnancy no other panic attacks occurred. After six months from the suspension of the drugs, the patient can no longer be classified as affected by panic attack according to the DSM-IV criteria.
