Nitrofurantoine

Nitrofurantoin Tablets (100 mg): Antibiotic for Urinary Tract Infections

Nitrofurantoin tablets contain the active ingredient Nitrofurantoin, a bacteriostatic and bactericidal Antibiotic primarily used to treat lower urinary tract infections (UTIs). While approved for human use, veterinarians commonly prescribe this medication on an extra-label basis for dogs and cats. Nitrofurantoin is quickly eliminated from the body and concentrates in the urine, making it an effective option for targeting susceptible bacteria within the bladder. Its use has increased in veterinary medicine, particularly for UTIs caused by multidrug-resistant bacteria.

Prescription Required

Nitrofurantoin is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. This is crucial because it is used to treat infections diagnosed via urine culture and susceptibility testing, and its effectiveness is limited to the lower urinary tract. Veterinary supervision is necessary to determine the correct dosage, duration, and to monitor for side effects like gastrointestinal upset, especially in animals with underlying kidney issues.
