UTI (cystitis) Treatment

The best UTI treatment for most uncomplicated infections is a short course of antibiotics. Treating UTI infections promptly helps relieve symptoms quickly and reduces the risk of the infection spreading to the kidneys. A SwiftDoctor clinician will recommend the most appropriate urinary tract infection treatment for you based on your symptoms and medical history.

For most non-pregnant women with an uncomplicated UTI, Nitrofurantoin and Trimethoprim are the antibiotics most commonly recommended as first-line treatment in the UK. The best antibiotic for UTI in women depends on individual factors such as allergies, pregnancy, and recent antibiotic use, which your SwiftDoctor clinician will review during your consultation.

In England, community pharmacists can supply antibiotics for uncomplicated UTIs in women aged 16–64 through the NHS Pharmacy First service, without a GP appointment. SwiftDoctor offers a similar online route: our UK-registered clinicians can assess your symptoms remotely and issue a private prescription for UTI medication, often with same-day dispatch.

Most people notice their symptoms start to improve within 1–2 days of starting antibiotics for UTI, though it's important to complete the full course even if you feel better sooner. If your symptoms haven't improved after 2–3 days, contact your prescriber, as you may need a different antibiotic or further assessment.

If your symptoms don't improve on a first course of UTI medication, it may indicate resistant bacteria or a different underlying cause, and a urine sample may be needed to identify the right antibiotic. Recurrent UTIs may also need a longer course or a preventative approach but your SwiftDoctor clinician can advise on next steps.

Seek urgent medical attention if you develop a high temperature, chills, back or side pain, nausea or vomiting alongside UTI symptoms, as these can indicate a kidney infection. Pregnant women, men, and anyone with recurrent or worsening symptoms should also seek prompt clinical advice rather than self-treating.

Yes, men can get urinary tract infections, although they are less common in men than in women. UTIs occur when bacteria enter the urinary tract and cause an infection, which can lead to symptoms such as a burning sensation when urinating, needing to urinate more often, cloudy or strong-smelling urine, or lower abdominal pain. Men with symptoms of a UTI should speak to a healthcare professional, as UTIs in men may sometimes be linked to an underlying condition that needs treatment.
