What is the strongest antibiotic for severe UTI?
For severe or complicated UTIs, intravenous antibiotics like ceftriaxone or gentamicin may be used in hospital settings. The choice depends on the bacteria and your medical history.
Detailed Medical Explanation
Severe UTIs, especially those involving the kidneys (pyelonephritis) or leading to sepsis, often require intravenous antibiotics such as ceftriaxone, gentamicin, or piperacillin-tazobactam. These are administered in hospital after urine and blood tests. The exact antibiotic is chosen based on sensitivity results and clinical assessment. NICE BNF: Severe UTI treatment.
Clinical Context
Clinics refer patients with severe or complicated UTI symptoms urgently to hospital for specialist care and IV antibiotics.
Evidence-Based Approaches
NHS and NICE recommend hospital care and IV antibiotics for severe or resistant UTIs to prevent complications.
