Nitrofurantoin Brand Names

Nitrofurantoin is available as macrocrystals formulation, which is the generic name itself rather than a specific brand name. 1

Available Formulations

The FDA-approved formulation is:

  • Nitrofurantoin (macrocrystals) - This is the standard oral formulation used for uncomplicated urinary tract infections 1

Clinical Context for UTI Treatment

While you asked about brand names, it's important to note that nitrofurantoin is widely recommended as a first-line treatment for uncomplicated UTIs in otherwise healthy adult women 2, 3:

  • Standard dosing: 100 mg orally every 6 hours (four times daily) for uncomplicated cystitis 2
  • Alternative dosing: 100 mg twice daily for 5 days is also recommended by European guidelines 3
  • Treatment duration: 5 days is the recommended duration for acute uncomplicated cystitis 2

Key Clinical Advantages

Nitrofurantoin demonstrates several advantages that make it a preferred first-line agent 3, 4:

  • Superior microbiological cure rates compared to fosfomycin 3
  • Low resistance rates - maintains excellent activity against E. coli despite over 60 years of use 5, 6
  • Minimal collateral damage to intestinal flora compared to fluoroquinolones and cephalosporins 3

Important Contraindications

Do not use nitrofurantoin in patients with 5:

  • Renal impairment of any degree
  • Last three months of pregnancy
  • Pyelonephritis or upper UTIs (insufficient tissue penetration) 2, 4
