The short answer is yes. The PI sheet lists it as one of the observed paradoxical reactions.
QUOTE
Psychiatric: Confusion, depression, amnesia, hallucinations, hysteria, increased libido, insomnia, psychosis, suicidal attempt (the behavior effects are more likely to occur in patients with a history of psychiatric disturbances).
The following paradoxical reactions have been observed: Excitability, irritability, aggressive behavior, agitation, nervousness, hostility, anxiety, sleep disturbances, nightmares, and vivid dreamshttp://www.rxlist.com/cgi/generic/clonaz_ad.htmI couldn't copy the text from the actual PI sheet, which is here:
http://www.rocheusa.com/products/klonopin/pi.pdfAs Chimpmaster said, with most drugs you can find somebody somewhere that had nearly anykind of adverse reaction. Usually they are pretty rare, but hey.
You should discuss this with your pdoc. A couple possibilities are: Take the med earlier so it doesn't disturb your sleep; possibililty that you may not need a benzo while you are sleeping; substituting a sleep aid for the benzo- probably a safer bet long term considering benzo addictability.
good luck.
