Antibiotic use can increase nerve damage risk: Study

Press Trust of India  |  London 

A common class of -- used to treat -- may increase a patient's risk of suffering a serious and potentially permanent form of nerve damage by almost 50 per cent.

Scientists from the in the UK looked at a database of 1.3 million adults issued one or more prescriptions of fluoroquinolone or amoxicillin-clavulanate with no diagnosis of at the outset of treatment.

has long been recognised as a potential side effect of -- that are commonly used to treat a variety of illnesses such as

The study, published in the journal JAMA Neurology, found that current use of systemic appeared to increase the risk of by 47 per cent, causing an additional 2.4 cases per 10,000 patients per year of treatment.

A person prescribed with amoxicillin-clavulanate were not significantly more likely to experience peripheral neuropathy.

The risk was higher for men and rose with age and with the length of fluoroquinolone treatment. A peripheral neuropathy diagnosis remained more likely to be diagnosed for up to six months after the fluoroquinolone prescription.

Older men, the group most likely to experience the condition after taking a 28-day course of fluoroquinolones, were said to have a one in 34,000 chance of doing so.

While the absolute risk of a peripheral neuropathy diagnosis remained low, the findings should still be considered as one of the different potential side effects before prescribing antibiotics, researchers said.

"The safety of has received a lot of attention regarding their potential to cause long-term side effects in some people," said Daniel Morales, from the

"One of these is peripheral neuropathy where nerves, most commonly affecting the lower limbs, can be affected, leading to numbness, pain, or problems with balance," Morales said in a statement.

"Fluoroquinolones are effective antibiotics but care professionals should recognise that peripheral neuropathy may rarely occur following fluoroquinolone therapy," he said.

"We observed that treatment with fluoroquinolones could increase the risk of peripheral neuropathy by around 50 per cent and that this risk may last for up to six months following treatment," he said.
