After standard antibiotics failed to shift a severe lung infection, Jane Allan was more than happy when her GP suggested she move onto a stronger antibiotic, ciprofloxacin.
Jane, who suffers from asthma, was a hospital pharmacist and remembered the excitement when ciprofloxacin became available in the early Nineties.
'It caused quite a buzz as it was one of a new class of powerful antibiotics that could be given as a pill, so patients could have treatment at home, and it quickly became very popular,' she recalls.
Yet Jane now blames the drug for the litany of health problems she suffers, including widespread muscle pain and weakness and severe fatigue.
Three years on, the once fit and sporty 50-year-old is unable to work. After 25 years in the NHS, she retired early on health grounds.
