RESULTS 22 ADRs were reported in our PVD involving fluoroquinolone and quinolone antibiotics in the period considered and that affected peripheral or central nervous system, tendons, muscles and joints. The mean patient age was 67,3 years (range: 17-92 years). 63,7% of the ADRs reported were serious, of which 22,7% caused hospitalization and 4,5% caused persistent/severe disability. 81,8% of the ADRs were reported by a healthcare professional (physician, pharmacist or other) and 18,2% by patient or a non-healthcare professional. -

Disabling and Potentially Permanent Side Effects Lead to Suspension Or Restrictions of Quinolone and Fluoroquinolone Antibiotics
16 November 2018 EMA/795349/2018 Disabling and potentially permanent side effects lead to suspension or restrictions of quinolone and fluoroquinolone antibiotics EMA has reviewed serious, disabling and potentially permanent side effects with quinolone and fluoroquinolone antibiotics given by mouth, injection or inhalation. The review incorporated the views of patients, healthcare professionals and academics presented at EMA’s public hearing on fluoroquinolone and quinolone antibiotics in June 2018. EMA’s human medicines committee (CHMP) has endorsed the recommendations of EMA’s safety committee (PRAC) and concluded that the marketing authorisation of medicines containing cinoxacin, flumequine, nalidixic acid, and pipemidic acid should be suspended. The CHMP confirmed that the use of the remaining fluoroquinolone antibiotics should be restricted. In addition, the prescribing information for healthcare professionals and information for patients will describe the disabling and potentially permanent side effects and advise patients to stop treatment with a fluoroquinolone antibiotic at the first sign of a side effect involving muscles, tendons or joints and the nervous system. Restrictions on the use of fluoroquinolone antibiotics will mean that they should not be used: • to treat infections that might get better without treatment or are not severe (such as throat infections); • to treat non-bacterial infections, e.g. non-bacterial (chronic) prostatitis; • for preventing traveller’s diarrhoea or recurring lower urinary tract infections (urine infections that do not extend beyond the bladder); • to treat mild or moderate bacterial infections unless other antibacterial medicines commonly recommended for these infections cannot be used. Importantly, fluoroquinolones should generally be avoided in patients who have previously had serious side effects with a fluoroquinolone or quinolone antibiotic. -

Fluoroquinolone and Quinolone Antibiotics: PRAC Recommends Restrictions on Use New Restrictions Follow Review of Disabling and Potentially Long-Lasting Side Effects
5 October 2018 EMA/668915/2018 Fluoroquinolone and quinolone antibiotics: PRAC recommends restrictions on use New restrictions follow review of disabling and potentially long-lasting side effects EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) has recommended restricting the use of fluoroquinolone and quinolone antibiotics (used by mouth, injection or inhalation) following a review of disabling and potentially long-lasting side effects reported with these medicines. The review incorporated the views of patients, healthcare professionals and academics presented at EMA’s public hearing on fluoroquinolone and quinolone antibiotics in June 2018. Very rarely, patients treated with fluoroquinolone or quinolone antibiotics have suffered long-lasting and disabling side effects, mainly involving muscles, tendons and bones and the nervous system. Following its evaluation of these side effects, the PRAC has recommended that some medicines, including all those that contain a quinolone antibiotic, should be removed from the market. This is because they are authorised only for infections that should no longer be treated with this class of antibiotics. The PRAC recommended that the remaining fluoroquinolone antibiotics should: • not be used − to treat infections that might get better without treatment or are not severe (such as throat infections); − for preventing traveller’s diarrhoea or recurring lower urinary tract infections (urine infections that do not extend beyond the bladder); − to treat patients who have previously had serious side effects with a fluoroquinolone or quinolone antibiotic; − to treat mild or moderately severe infections unless other antibacterial medicines commonly recommended for these infections cannot be used; • be used with caution especially for the elderly, patients with kidney problems, patients who have had an organ transplantation or those who are being treated with a systemic corticosteroid. -

Disabling and Potentially Permanent Side Effects Lead to Suspension Or Restrictions of Quinolone and Fluoroquinolone Antibiotics
11 March 2019 EMA/175398/2019 Disabling and potentially permanent side effects lead to suspension or restrictions of quinolone and fluoroquinolone antibiotics On 15 November 2018, EMA finalised a review of serious, disabling and potentially permanent side effects with quinolone and fluoroquinolone antibiotics given by mouth, injection or inhalation. The review incorporated the views of patients, healthcare professionals and academics presented at EMA’s public hearing on fluoroquinolone and quinolone antibiotics in June 2018. EMA’s human medicines committee (CHMP) endorsed the recommendations of EMA’s safety committee (PRAC) and concluded that the marketing authorisation of medicines containing cinoxacin, flumequine, nalidixic acid, and pipemidic acid should be suspended.
