Furadantin (Nitrofurantoin) Buyer and Patient Handbook in Singapore
What is Furadantin?
Furadantin (Nitrofurantoin) is a urinary antiseptic belonging to the nitrofuran class, used to treat uncomplicated urinary-tract infections (UTIs). It is approved by the US FDA and the European Medicines Agency and is available in Singapore as oral tablets. The medication works locally in the urinary tract, where it reaches concentrations high enough to eradicate the common bacteria that cause UTIs.
Who Should Use Furadantin?
- Adults diagnosed with uncomplicated cystitis (Bladder Infection)
- Patients with a confirmed nitrofurantoin-sensitive pathogen
- Individuals without significant kidney impairment (creatinine clearance ≥ 30 mL/min)
- Those who can swallow tablets and follow a short-course regimen
How Does It Work?
Nitrofurantoin is reduced by bacterial enzymes to reactive intermediates that damage bacterial DNA, proteins, and enzymes. This multi-target attack prevents the bacteria from reproducing, allowing the immune system to clear the infection. Because the drug is concentrated in urine, systemic side effects are limited.
Why Choose Furadantin?
- Proven efficacy for most strains of E. coli and other common UTI pathogens.
- Low resistance rates compared with many broad-spectrum Antibiotics.
- Cost-effective - the brand name is widely available, and a generic version containing the same active ingredient offers a cheaper option.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- 50 mg tablet: 1 tablet every 6 hours (four times daily) for 5-7 days.
- 100 mg tablet: 1 tablet every 12 hours (twice daily) for 5-7 days.
How to Take
- Swallow the tablet whole with a full glass of water.
- Take with food or milk to reduce stomach irritation.
- Do not crush or chew the tablet.
Missed Dose
If you miss a dose, take it as soon as you remember unless the next scheduled dose is within 2 hours, in which case skip the missed dose. Do not double-dose.
Overdose
Seek immediate medical help if you suspect an overdose. Symptoms may include Nausea, Vomiting, dizziness, or rapid breathing.
Special Populations
- Elderly: Use the 50 mg dose and monitor renal function.
- Pregnancy: Classified as Category B (generally safe in the second and third trimesters for short courses).
- Renal impairment: Avoid if creatinine clearance < 30 mL/min.
Lifestyle & Diet
- Avoid taking antacids or supplements containing magnesium/aluminum within 2 hours of the dose, as they may reduce absorption.
- No specific food restrictions, but maintain adequate hydration to help flush bacteria from the urinary tract.
Precautions and Warnings
- Do not use if you have a known allergy to nitrofurantoin or other nitrofurans.
- Discontinue if you develop rash, fever, or signs of liver injury (jaundice, dark urine).
- Long-term use may cause pulmonary toxicity; limit therapy to the shortest effective duration.

Frequently Asked Questions
How long does a typical course of Furadantin last?
A usual treatment lasts 5-7 days, depending on the severity of the infection and the dose prescribed.
Can I take Furadantin if I am pregnant?
It is generally considered safe in the second and third trimesters for short courses, but you should discuss any concerns with your healthcare professional.
Will Furadantin interact with my daily vitamin C supplement?
Vitamin C does not affect nitrofurantoin absorption, so it can be taken together.
Is it okay to drink alcohol while on Furadantin?
Moderate alcohol consumption does not interfere with the medication, but excessive drinking may increase stomach irritation.
What should I do if I forget to take a dose before bedtime?
Take the missed dose as soon as you remember unless the next dose is due within 2 hours, then skip and continue with your regular schedule.
Why does my urine turn a dark yellow colour?
Nitrofurantoin can cause a harmless colour change in urine. Stay hydrated; the colour will clear once the drug is eliminated.
Can I use Furadantin for recurrent UTIs without a doctor's review?
Repeated courses should be evaluated by a healthcare professional to ensure appropriate use and to rule out underlying issues.

Reviews
First day on Furadantin for a stubborn UTI. Doctor said it's the go-to here in SG. Already feeling that weird, almost metallic taste in my mouth. Hoping it kicks in fast because the burning is no joke. Taking it with a full meal like the pharmacist said, but my stomach's still a bit iffy.
Got prescribed this for a kidney infection. The 100mg dose is strong. Nausea hit me like a truck after the first pill. Saw online to take it with yogurt or a banana, and it's a lifesaver. Seriously, don't take it on an empty stomach. The side effects are rough but the infection is worse.
Been on Furadantin long-term for chronic UTIs. It's kept me infection-free for over a year now. The key is timing: I take my 50mg pill right after dinner, never had nausea. The trade-off is the brownish urine - freaked me out at first, but it's normal. Also, my lips get super dry, lip balm is a must.
This is my third course. It works, but you have to be smart about it. I split the 100mg pill in half and take it twice a day with a big glass of milk. Completely eliminates the stomach upset. The only downside is the fatigue; I'm just wiped out for the whole week I'm on it. Small price to pay for relief.
After trying everything, Furadantin is the only thing that works for my recurrent UTIs. Been on a low-dose prophylaxis for 6 months. You get used to the side effects. The hack: avoid caffeine while you're on it. Makes the jitters and headaches way worse. It's a bit of a drag, but better than constant antibiotics.
I keep a stash for whenever I feel a UTI coming on. Taking one 100mg pill at the first sign of symptoms usually nips it in the bud. But yeah, the lung feeling is real - sometimes I get a bit short of breath, so I never take it for more than 3 days without seeing a doc. It's powerful, but you have to be cautious.
Furadantin cleared my UTI in two days, which was amazing. But it also gave me a horrible yeast infection. So it's a double-edged sword. I had to get fluconazole after finishing the course. It works great for the bacteria, just be prepared for the fungal fallout. Probiotics didn't really help me, sadly.
Took this for a UTI after a surgery. It worked, but the brain fog was intense. I couldn't concentrate at all. Also had these weird, vivid dreams. I'm glad I only needed a 5-day course. Would I take it again? Maybe, but only if I didn't have to work or study. The side effects are no joke for your mind.
