Inclusion Criteria:

• Participants must be greater than or equal to (>=)18 years of age and less than or equal to (<=)70 years.
• The participant has 2 or more of the following clinical signs and symptoms of uncomplicated urinary tract infections (uUTI) with onset less than or equal to (<=) 72 hours of the screening assessment: dysuria, frequency, urgency, or lower abdominal pain.
• Participant has nitrite and pyuria from a pretreatment clean-catch midstream urine sample
• Participants with body mass index (BMI) greater than or equal to (>=) 19.0 kilograms per square meter (kg/m^2).

• A female participant is eligible to participate who is not pregnant (as confirmed by a highly sensitive pregnancy test before the first dose of study intervention) or breastfeeding and one of the following conditions apply:

  1. Woman participant of non-childbearing potential (WONCBP) Or
  2. Woman participant of childbearing potential (WOCBP) using a contraceptive method that is highly effective, with a failure rate of less than (<) 1 percentage (%), during the study intervention period
• Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and protocol.

Exclusion Criteria:

• The participant has a BMI greater to or equal (>=) 40.0 kg/ m^2 or a BMI >=35.0 kg/ m^2 with obesity related health conditions such as high blood pressure or uncontrolled diabetes (non-fasting glucose value >300 milligram/deciliter [mg/dL]).
• The participant is immunocompromised or has altered immune defenses that may predispose the participant to a higher risk of treatment failure and/or complications.
• The participant has symptoms known or suspected to be caused by another disease process, such as asymptomatic bacteriuria, overactive bladder, chronic incontinence, or chronic interstitial cystitis.
• The participant has an anatomical or physiological anomaly that predisposes the participant to UTIs or may be a source of persistent bacterial colonization, including calculi, obstruction of the urinary tract, primary renal disease, or neurogenic bladder, or the participant has a history of anatomical or functional abnormalities of the urinary tract.
• The participant has an indwelling catheter, nephrostomy, ureteral stent, or other foreign material in the urinary tract.
• The participant who, in the opinion of the investigator, has an otherwise complicated UTI, an active upper UTI (e.g., pyelonephritis, urosepsis), signs and symptoms onset >=96 hours before the screening assessment, or a temperature >=101 degree Fahrenheit (°F) (>=38 degree Celsius [°C]), flank pain, chills, or any other manifestations suggestive of upper UTI.
• The participant has anuria, oliguria, or significant impairment of renal function.
• The participant presents at enrollment with a suspected sexually transmitted infection.
• A positive confirmation of Coronavirus Disease 2019 (COVID-19) infection, or high clinical index of suspicion for COVID-19.
• The participant has received treatment with other systemic antimicrobials or systemic antifungals within 4 weeks before study entry.
• Regular alcohol consumption within 6 months prior to the study with an average weekly intake of >14 units for females and one unit is equivalent to approximately 8 g of alcohol: a half-pint (250 ml) of beer, one glass (125 mL) of wine or one (35 mL) measure of spirits.
• Unable to take nitrofurantoin. E.g. hypersensitivity to the active substance.
