UTI's Flashcards
Uncomplicated UTI Symptoms
Also called cystitis
dysuria hematuria pyuria frequency urgency suprapubic discomfort
Lower UTI (cystitis) First Line Treatment
- nitrofurantoin
- TMP/SMX (sulfa drug)
- fosfomycin
due to effectiveness and low risk for resistance
IF one of these dose not work, try another before going to beta lactam or fluoroquinolone
IF you cannot take these due to allergy, tolerating, or concern for resistance THEN take beta-lactam or fluoroquinolone

AVOID IN PYELONEPHRITIS
Notes:
MIX WITH 3-4oz of WATER
Recurrent UTI Outline
2 or more infections in 6 months
OR
3 or more infections in 1 year
With recurrent: each episode has resolution to symptoms
Recurrence is caused by same bacterium
Collateral Damage
- Ecological A/E of antibiotic Therapy
ie CDIFF
2ND LINE for Recurrent UTI or Alternative Needed
- Cannot tolerate due to allergy or s/e of first liners
- Women whose urine culture shows resistance to preferred antibiotics
- beta lactams and fluoroquinolones have higher risk of collateral damage
Beta-Lactams (5-7 days) PCN -Amoxicillin-Clavulanate 500mg BID Cephalosporins -Cefadroxil 500mg BID -Cefdinir 300mg BID -Cefpodoxime 100mg BID
- Amoxicillin or Ampicillin should NOT be used due to limited effectiveness and resistance concerns*
- Less efficacy and more side effects than first liners*
Fluoroquinolones
- ciprofloxacin 250mg BID
- ciprofloxacin ER 500mg daily
- levofloxacin 250mg daily
- ofloxacin 200mg daily
- Fluoroquinolones reserved for more complicated UTI’s*
- Concern with A/E: seizures, QT prolong, tendonitis, tendon rupture, peripheral neuropathy, aortic rupture, CDIFF
- moxifloxacin is not used bc lower concentration in urine*
- More effective than beta lactams but higher risk of resistance and greater risk of collateral damage*
Complicated UTI’s
Any of the following features:
- fever over 99.9
- signs of systemic (chills, rigors, significant fatigue, malaise beyond baseline)
- Flank Pain/ CVA pain
- Pelvic or Perineal Pain (men can suggest prostatitis)
Treatment: Fluoroquinolones
Acute Pyelonephritis
- Common in kids, older adults and women of child bearing ages
- Fever, chills, flank pain, dysuria, frequency, urgency, pyuria, usually bacturia
- EColi 90% of infections
> mild-mod: treat with abx at home
> severe: hospital IV abx
Treatment of Acute Pyelonephritis
Hospitalization: s/s sepsis, critically ill, persistant high fevers over 101, cant maintain hydration or take meds
Ciprofloxacin 500mg BID x 7 days
Ciprofloxacin ER 1000mg Daily x 7 days
Ofloxacin 400mg BID x 7 days
Levofloxacin 750mg Daily x 5 days
Phenozopyridine
OTC: pyridium, uristat, AZO
- No more than 2 days
- Can mask symptoms
- Not replacement of Abx or Medical Treatment
S/E: orange/red urine staining of contacts orange/red HA Dizziness Rash Fever Itching Serious S/E are usually dose dependent (over dose, using too long)
Non Pharm UTI Prevention
Good Hygiene - wiping - pre/post coital voiding - avoiding tampons, hottubs, douching Cranberry Juice Increase water intake
Pharm UTI Prevention
- Highly effective against reoccurrence > usually with colonization - Collateral damage high risk > Cdiff, resistance - Continuous 6-12 mo - Intermittment pre post coital - Treatment could be for years - Only effective while taking the abx > UTI frequency resumes after stopping abx
