Check before prescribing

• Asymptomatic bacteriuria should NOT be treated — especially in older adults, where positive dipstick without symptoms is common and not infection.
• Tighten exclusions: male patient, pregnancy, pyelonephritis symptoms (flank pain, fever, vomiting), recurrent, indwelling catheter, recent antibiotic course, known resistance.
• TMP-SMX: screen for hyperkalemia risk (ACEi/ARB/spironolactone, CKD) and warfarin interaction (INR spike) before prescribing.
• Reassess at 48–72 h; if no improvement, switch agent or refer.

Follow-up

Sets the reminder and the documents

Phone or in-person check-in 2-3 days after starting treatment to confirm symptom resolution and identify treatment failure.

Ontario billing

Bill as an Ontario minor-ailment service only after checking the current PIN (prescription/no prescription · in-person/virtual) in the Ministry notice. Ontario permits one claim per eligible recipient per minor ailment per day, regardless of outcome or pharmacy visited; annual maximums vary by PIN family.
