Drugs for urinary tract infection: what to know

Antibiotics target bacteria in the urinary system, but not every burning or frequent urination symptom is caused by bacteria. A clinician may ask about your symptoms and arrange a urine test, especially if symptoms are severe, recurrent, occur during pregnancy, or affect a child or man. The medicine, dose, and duration depend on the suspected infection and your medical history. Pain relief may help discomfort, but it does not clear an infection. Take an antibiotic exactly as directed and do not share leftover medicine.

Tell the prescriber about allergies, kidney problems, pregnancy, breastfeeding, and medicines or supplements you already take. Drink fluids regularly unless a clinician has told you to restrict them. Follow the label, complete the prescribed course unless the prescriber changes it, and seek advice if vomiting prevents you keeping doses down. Symptoms should be reviewed if they do not start improving after treatment begins or return soon after it ends. Repeated infections may need a different plan rather than repeated self-treatment.

Get urgent medical help for fever, shaking chills, pain in the side or back, confusion, faintness, severe weakness, or repeated vomiting. These can signal a kidney infection, dehydration, or a serious infection affecting the whole body. A child, pregnant person, older adult, or someone with a weakened immune system should seek prompt clinical advice for urinary symptoms. Call emergency services for collapse, trouble breathing, or rapidly worsening illness.

Ask which symptoms make an antibiotic appropriate, whether a urine test is needed, how to take each dose, which side effects need attention, and what to do if symptoms persist. Also ask whether another condition, such as prostatitis, could explain recurrent symptoms.
