People who take Adderall may be at a much greater risk of having a mental breakdown, a study suggests.
Those with a prescription for the ADHD drug or other stimulants were over 60 percent more likely to suffer psychosis or mania than people not using the meds.
Stronger doses raised the risk further – people who took the max dose recommended by the FDA were at a fivefold higher likelihood.
The research looked at two groups of people who had a history of depression, anxiety or other mental health issues that put them at risk of psychosis.
Study author Lauren Moran, a researcher at Mass General Brigham, said: ‘Our results show that it is clear that dose is a factor in psychosis risk and should be a chief consideration when prescribing stimulants.’
