Diarrax is a medical grade laxative that enjoyed a brief vogue in the mid-nineties United Kingdom, where it appeared on the scene just as the privatisation of the NHS really got going.
Diarrax would not be noteworthy at all except for its tangential connection to one of the worst scandals in Scottish medical history: a symposium on euthanasia it sponsored for the Midlothian NHS Trust, at which the head of the trust, Stephen Lime, recruited one Dr Jeremy Ponsonby to serve as a provider of involuntary euthanasia to several patients in the Trust’s geriatric facility.
It is believed that the resulting bad publicity may have tainted the brand, as Diarrax is no longer in common use in NHS facilities.
