Decades of drug side-effectsNow, many years ago, Brian Deer's investigation for The Sunday Times of London shone the first light on an appalling toll of sickness, disability and death caused by the drug known most often as Bactrim, Septra, Sulfatrim and Septrin
His reports led to an almost complete ban in the UK, but elsewhere around the world use of Bactrim - Septra continues unabated, and continues to cause damage from its side-effects
Deer's website continues to inform, and receives large numbers of emails recounting real stories of what can happen. If you have a story, please contribute, which may help others |

Toll of suffering: The first reports in the newspaper series exposed deaths and injuries in the UK, kept hidden for decades, caused by the antibiotic known most commonly as Bactrim, Septra, Septrin, Apo-Sulfatrim, SMZ-TMP and co-trimoxazole, but with many other names worldwide. The opening story appeared on page 1 of The Sunday Times of London |

Small victory: Aware of the impending magazine report on Kate Reid, the British government abruptly altered the drug's official prescribing indications, as reported in the newspaper on Sunday July 9 1995. But in the rest of the world little changed. The worldwide web is today loaded with sites recommending the product |

Bactrim by other names: The British campaign focused on the dominant brands in the UK - Septrin and Bactrim. But the drug's contents - a combination of sulfamethoxazole (from Roche) and trimethoprim (from Wellcome) - is marketed worldwide in dozens of guises, causing confusion for those who wish to avoid these chemicals, and obscuring side effects.

A doctor writes: Having prescribed a needlessly-dangerous pharmaceutical for most of their professional careers, many family doctors were outraged by the challenge over Bactrim - Septrin - Septra. Some felt their patients were alarmed unfairly by Deer's reports which stressed side-effects, rather than typical experiences. A number couldn't believe what they were reading

Inventors of trimethoprim in Bactrim-SeptraHard sell: The Bactrim - Septrin - Septra - SMZ-TMP investigation sprang from Brian Deer's inquiries for The Sunday Times into the extraordinary Wellcome organization, a part-drug-company-part-charity, which was broken up after the campaign. Here's also a memo on Henry Wellcome, the American-born founder

Wellcome's world: Septrin was the foundation upon which the Wellcome organization rose. But, as this chart from The Sunday Times reveals, a research funding money-go-round may have led regulators and experts on side-effects to give it an easy ride. Specialists and researchers who promoted Wellcome drugs often thought they might be helped by the charity
