Patients with psychosis warned of ‘energy drink’ dangers
PATIENTS treated for schizophrenia may be vulnerable to recurrence of psychosis after the consumption of caffeine-containing “energy drinks”, a psychiatrist warns.
Associate Professor David Menkes, from the University of Auckland, NZ, reported a transient relapse in a patient stabilised on risperidone who consumed several 60 ml bottles of the drink Demon Shot.
Promoted as “insanely intense”, it contains 200 mg of caffeine, plus taurine, guarana and B-group vitamins.
The drinks, popular among patients treated for schizophrenia, may partially reverse the unpleasant effects of a dopamine blockade, he said.
