GoodRx Nitrofurantoin: What You Need to Know About Cost, Use, and Benefits
When it comes to treating urinary tract infections (UTIs), nitrofurantoin is one of the most trusted antibiotics prescribed by doctors. But with rising healthcare costs, many patients are turning to platforms like GoodRx to manage their medication expenses. In this blog post, we’ll explore everything you need to know about Nitrofurantoin, how GoodRx can help you save money on your prescription, and why this medication remains a top choice for uncomplicated UTIs.
What Is Nitrofurantoin?
Nitrofurantoin is an antibiotic that fights bacteria in the urinary tract. It’s commonly prescribed to treat uncomplicated urinary tract infections caused by E. coli, Enterococci, and other bacteria. The medication is typically taken in either macrocrystalline form (Macrodantin) or monohydrate/macrocrystals (Macrobid).
Nitrofurantoin works by damaging bacterial DNA, making it hard for the bacteria to survive and multiply. It is especially effective in the urinary system because it is excreted primarily through urine, directly reaching the site of infection.
Why Do Doctors Prescribe Nitrofurantoin?
Nitrofurantoin is most often prescribed for:
- Acute uncomplicated UTIs (especially in women)
- Prevention of recurrent UTIs
- Post-surgical urinary infection prevention
It’s not typically used for kidney infections (pyelonephritis) or systemic infections because it doesn’t reach high concentrations outside the urinary tract.
Common Brand Names:
- Macrobid – Taken twice daily
- Macrodantin – Usually taken four times daily
- Generic Nitrofurantoin – A cost-effective option with the same active ingredient
Nitrofurantoin Dosage and Use
Typical adult dosage:
- Macrobid: 100 mg twice daily for 5–7 days
- Macrodantin: 50–100 mg four times daily
The medication is best taken with food, as it enhances absorption and minimizes stomach upset.
Important Tips:
- Complete the full course even if symptoms improve early.
- Drink plenty of water to help flush the bacteria from the urinary tract.
- Inform your doctor if you have kidney problems, as the drug may not be suitable in cases of reduced kidney function.
Possible Side Effects of Nitrofurantoin
Like all medications, nitrofurantoin may cause side effects. Most are mild and temporary.
Common Side Effects:
- Nausea
- Loss of appetite
- Headache
- Urine discoloration (usually dark yellow or brown)
Serious Side Effects (rare):
- Lung issues (especially with long-term use)
- Liver problems
- Nerve damage (especially in people with diabetes or kidney disease)
If you experience shortness of breath, persistent cough, jaundice, or tingling/numbness, seek medical help immediately.

Nitrofurantoin vs Other UTI Antibiotics
Doctors choose antibiotics based on the patient’s health, bacterial resistance, and the infection’s severity. Let’s see how Nitrofurantoin compares:
| Antibiotic | Common Use | Duration | Effectiveness for UTIs |
|---|---|---|---|
| Nitrofurantoin | Uncomplicated UTIs | 5–7 days | Very effective |
| Trimethoprim-Sulfamethoxazole (Bactrim) | UTIs, other infections | 3–5 days | Effective, but resistance increasing |
| Fosfomycin | UTIs (one-dose treatment) | 1 day | Moderate |
| Ciprofloxacin | Complicated UTIs | 3–7 days | Effective, but often avoided due to side effects |
Nitrofurantoin is a first-line choice due to its narrow spectrum, low resistance, and safety profile in most women.
Who Should Avoid Nitrofurantoin?
Nitrofurantoin is not suitable for everyone. It should be avoided or used with caution in:
- Pregnancy (late third trimester)
- Infants under 1 month old
- Patients with kidney impairment (eGFR <60 mL/min)
- Those with a history of lung/liver/nerve reactions to the drug
Always inform your healthcare provider of your full medical history before starting nitrofurantoin.
