I was prescribed Pramipexole for restless leg syndrome some years ago, and the information leaflet was pretty specific about the impulsive behavior side effects. The Spanish leaflet lists as "Frequent" (up to 1 out of 10 patients) things like: "Needs to behave in an unusual way", "Hallucinations", "Confusion", "abnormal dreams", "Insomnia"... I in fact had lots of weird dreams and nightmares. It also lists as "Less frequent" (up to 1 out of 100) things like: "Paranoia", "Delusion", "Amnesia", "Hyperkinesis", "Fainting", "Concerns", "Inability to resist the impulse, instinct or temptation to take an action that may be harmful to yourself or others, which may include: [buy/gamble/sex/eat]"... I thankfully had none of that, but 1% looks like a too high probability for me for that kind of effects.
