Donald Trump’s health secretary is no stranger to controversy.

Known for espousing discredited claims on everything from vaccines to paracetamol, Robert F Kennedy Jr has used his position as Secretary of Health and Human Services (HHS) within the Trump administration to ride roughshod over the medical establishment in his mission to “Make America Healthy Again”.

Yet one of his recent policies could be his most radical yet – with significant consequences for millions of Americans.

Last month, the HHS outlined plans to prevent what it called the “overmedicalisation” of mental health by curbing “psychiatric overprescribing”.

Kennedy said he was taking “clear and decisive action to confront our nation’s mental health crisis by addressing the overuse of psychiatric medications – especially among children”.
