Most urinary tract infections need a short course of antibiotics prescribed by a doctor. Drinking plenty of water and pain relief help, but self-buying antibiotics drives resistance and can miss a kidney infection.
Antibiotics need a doctor. This lists medicines commonly used for this condition to help you understand your options — it is NOT a prescription. Do not self-medicate: the right choice and dose depend on the cause, your health and other medicines, and prescription drugs (especially antibiotics) need a doctor. Misusing antibiotics drives resistance.
Frequently asked questions
What antibiotic is used for a UTI?
Common choices include nitrofurantoin, fosfomycin and cotrimoxazole, chosen by a doctor and guided by a urine test. Do not self-medicate with antibiotics.
Can a UTI be treated without antibiotics?
Mild cases can sometimes settle with fluids, but most bacterial UTIs need antibiotics. Fever or back pain suggests a kidney infection needing urgent treatment.
Why should I not self-buy UTI antibiotics?
Wrong or unnecessary antibiotics drive resistance, may not match the bacteria, and can mask a more serious kidney infection. A doctor should guide treatment.
