Frequently Asked Questions About Nitrofurantoin
What type of bacteria does nitrofurantoin kill?
Nitrofurantoin kills bacteria that most often cause urinary tract infections . It generally targets bacterial strains of Escherichia coli , Klebsiella, Enterococci, and Staphylococcus aureus. It only kills bacteria in the urinary tract and wonât work for infections found in other areas of the body.
Who shouldnât take nitrofurantoin ?
You shouldnât take nitrofurantoin if you have a history of severe kidney or liver problems, if you are urinating less than usual or not at all, or if you are in the last 2 to 4 weeks of a pregnancy. In addition, some versions of nitrofurantoin shouldnât be used in certain age groups of children, because there havenât been any good studies to see how safe and how well the antibiotic works in these children. Macrobid and its generics arenât FDA-approved for use in children under 12 years old, while Macrodantin capsules, Furadantin oral suspension, and their generics arenât FDA-approved for use in children under 1 month of age.
What type of antibiotic is nitrofurantoin ?
Nitrofurantoin is known as a nitrofuran antibiotic. This is currently the only product available in the United States that belongs to this class of medication. It isnât related to other antibiotics, such as penicillin or sulfa medications ), so providers might prescribe nitrofurantoin if you are allergic to other antibiotics.

Bladder Infection Vs Kidney Infection
The main difference between a bladder infection and a kidney infection is when bacteria have built up and infected the urinary tract system. Although most kidney infections result from untreated bladder infections that migrate to the kidneys, a kidney infection can occur in other ways.
Overall, bladder infections are more common than kidney infections and considered less complicated, especially since kidney infections can lead to serious illness if infections spread through the bloodstream.
A critical difference between bladder infection and kidney infection symptoms is the increased likelihood of illness associated with the infection migrating to the kidneys. The signs and symptoms of a bladder infection that can remain the same even after the infection spreads to the kidneys include:
- A fever remaining under 101 degrees Fahrenheit
- Pain and pressure in the pelvis
- Painful or burning urination
- Dark and cloudy urine that may appear red from blood
- Bad-smelling urine
- Pain in the abdomen
Additional signs and symptoms that indicate an infection has spread to the kidneys include nausea, vomiting, chills, shaking, a fever exceeding 101 degrees Fahrenheit, and, particularly in the elderly, confusion.
What Are The Causes Of A Uti
UTIs develop when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. The urinary system is designed to exclude microscopic invaders, but the defense of the urinary system can indeed fail. Once that occurs, bacteria latch on and grow into a full-scale infection.
If youre in recovery from alcohol addiction, its essential to avoid alcohol. Dehydration from consuming too much alcohol can contribute to the development of a UTI, but will also not directly cause one. Other factors that can encourage the growth of bacteria, leading to a UTI, are:
- Not drinking enough fluids
- Purposely holding in urine for long periods
- Spinal cord injuries or other nerve damage that makes the bladder difficult to empty regularly and completely
- Conditions or situations that block the flow of urine, such as a tumor, kidney stone, enlarged prostate, or sexual intercourse
- Diabetes and other conditions that reduce the ability of the bodys immune system to fight off infection
- Hormonal changes in the urinary tract of pregnant women make it easier for bacteria to spread through the ureters and to the kidneys

Treatment Strategies For Recurrent Utis
Recurrent urinary tract infections, defined as three or more UTIs within 12 months, or two or more occurrences within six months, is very common among women these but arent treated exactly the same as standalone UTIs. One of the reasons: Continued intermittent courses of antibiotics are associated with allergic reactions, organ toxicities, future infection with resistant organisms, and more.
Because of this, its strongly recommended that you receive both a urinalysis and urine culture from your healthcare provider prior to initiating treatment. Once the results are in, the American Urological Association suggests that healthcare professionals do the following:
- Use first-line treatments. Nitrofurantoin, TMP-SMX, and fosfomycin are the initial go-tos. However, specific drug recommendations should be dependent on the local antibiogram. An antibiogram is a periodic summary of antimicrobial susceptibilities that helps track drug resistance trends.
- Repeat testing. If UTI symptoms persist after antimicrobial therapy, clinicians should repeat the urinalysis, urine culture, and antibiotic susceptibility testing to help guide further management.
- Try vaginal estrogen. For peri- and post-menopausal women with recurrent UTIs, vaginal estrogen therapy is recommended to reduce risk of future UTIs.
Antibiotics For A Kidney Infection
Antibiotics are the main treatment for a kidney infection, and are usually the only treatment thats needed.
If your doctor strongly suspects that you have a kidney infection based on your symptoms, you may be immediately prescribed an antibiotic that targets the most common bacteria that cause kidney infections.
Once your lab test results are in, your doctor may adjust your prescription based on the exact type of bacteria causing your infection. These antibiotics may be taken by mouth or IV.
Usually, your symptoms will start to get better within a few days of starting on antibiotics. But even if you feel better, its important to take the full course of antibiotics youve been prescribed.
Depending on the specific drug you take, your course of antibiotics will typically last for 5 to 14 days. Taking the full course ensures that all bacteria causing your infection are eliminated.
Antibiotics used to treat kidney infections include:

Antibiotics That Shouldn’t Be A First Choice For Uncomplicated Utis
Other antibiotics appear to be overused, and some physicians may misuse non-recommended antibiotics as first-line treatments. Ciprofloxacin is used in 35% of uncomplicated UTIs, while levofloxacin is used in 2%. These antibiotics can be important treatments in some cases of more complicated UTIs, but can have dangerous side effects.
The U.S. Food and Drug Administration warns that the use of these drugs should be restricted because of their potentially disabling side effects involving tendons, muscles, joints, nerves and the central nervous system. Additionally, in many parts of the country, bacteria commonly causing UTIs are becoming resistant to these antibiotics.
Who Can And Cannot Take Nitrofurantoin
Nitrofurantoin can be taken by adults including pregnant and breastfeeding women.
Nitrofurantoin is not suitable for everyone. To make sure its safe for you, tell your doctor if you have:
- ever had an allergic reaction to nitrofurantoin or any other medicines in the past
- either of the rare inherited conditions: porphyria or glucose-6-phosphate dehydrogenase deficiency
- severe kidney disease
- any illness causing severe weakness
- anaemia or vitamin B deficiency
When Should You Go To The Hospital For A Kidney Infection
Kidney infection is a potentially hazardous illness. Early diagnosis and treatment are crucial to prevent potentially permanent loss of kidney function. If you notice kidney infection symptoms such as pain in your side, fever, or nausea, see a doctor immediately. If you canât make an appointment with your regular doctor, do not hesitate to visit urgent care or an emergency room.

When Should I Give Nitrofurantoin
For the treatment of a UTI
- Nitrofurantoin is usually given four times each day. This is usually first thing in the morning, at about midday, late afternoon and at bedtime. Ideally, these times should be about 4 hours apart .
- Modified-release capsules are taken twice each day, once in the morning and once in the evening. Ideally, these times are 1012 hours apart, for example some time between 7am and 8 am, and 7pm and 8 pm.
For the prevention of UTI
- Nitrofurantoin is given once a day, usually in the evening.
Give the medicine at about the same time each day so that this becomes part of your childs daily routine, which will help you to remember.

Treatment For Uncomplicated Utis
UTIs can often be successfully treated with antibiotics prescribed over the phone. In such cases, a health professional provides the people with 3 to 5-day antibiotic regimens without requiring an office urine test. This course is recommended only for women who have typical symptoms of cystitis, who are at low risk for recurrent infection, and who do not have symptoms suggesting other problems. It is always best to have a urine culture done before starting antibiotics when possible.
Oral antibiotic treatment cures nearly all uncomplicated UTIs, although the rate of recurrence remains high. To prescribe the best treatment, the doctor should be made aware of any drug allergies of the person.
The following antibiotics are commonly used for uncomplicated UTIs:
After an appropriate course of antibiotic treatment, most people are free of infection. If the symptoms do not clear up within the first few days of therapy, doctors may suggest an alternate course of antibiotics. This may depend on the result of the urine culture. A urine culture may be ordered in order to identify the specific organism causing the condition if not done prior to starting antibiotics.
It should be noted that resistance to many of the commonly used antibiotics is growing and this is why it is now recommended to culture the urine before starting antibiotics. This helps reduce the overuse of these medications.

Is Nitrofurantoin Safe For Breastfeeding Or People With Kidney Problems
Its not recommended to breastfeed on Nitrofurantoin if a baby is less than one month old. As Nitrofurantoin can pass via the breast milk.
Id talk to your doctor about other medicines that are safer to use with breastfeeding. Specifically penicillin medicines.
The same goes for people who have kidney problems as the medication can build up in the bloodstream to very high levels and other antibiotic choices may be a better fit for you.
Overall, this is really good medicine for urinary tract infections but some people cant take it for the various reasons that I mentioned before. I think it as an antibiotic that its often overlooked but its quite effective.
The more common side effects of nitrofurantoin can include:

What Is A Uti Anyway
A UTI, or urinary tract infection, happens when bacteria enters into any part of your urinary system, which includes the urethra, the bladder, the kidneys or the uterus. If not flushed out of the system, the bacteria can lead to an infection, or a UTI.
If youve ever had a UTI , you probably havent forgotten the symptoms. UTIs are very unpleasant, to say the least, and are often accompanied with one or more of the following:
A burning sensation when urinating
A strong urge to urinate often, usually passing only small amounts of urine at a time.
Cloudy and/or strong smelling urine

A Lesser Risk To Develop An Antibiotic
When you take a pill your small intestines quickly absorb nitrofurantoin, 75% of the dose is quickly metabolized by the liver, and 25% of the dose is excreted in the urine.
The antibiotic enters the bacterial cells and damages the genetic material of the offending bacteria, affects respiration, certain metabolic processes, and other macromolecules within the bacterial cell and eventually leads to the death of the bacteria.
This means that the bacteria cannot reproduce and repair themselves. Since the mechanism of action is unique and complex it is harder for the bacteria to develop resistance.

What Is The Difference Between A Bladder Infection And A Kidney Infection
Kidney and bladder infections are both considered urinary tract infections. Although they share similar symptoms, there are differences between the two. A kidney infectionâs signs and symptoms vary significantly from person to person and normally develop within a day or as fast as a few hours.
Understanding the difference between a bladder and kidney infection can ensure you take the proper steps towards healing and speeding up doctor consultation sessions.

What Is Nitrofurantoin
Nitrofurantoin is the generic name for an FDA-approved antibiotic sold under the brand names Macrobid, Macrodantin, and Furadantin. This prescription is usually taken in pill or capsule form. It works by killing the bacteria that cause urinary tract infections in the urethra, bladder, and/or kidneys.
How To Take And Store
Nitrofurantoin should be taken with food, which improves drug absorption. The oral suspension can also be mixed with fruit juice, milk, or formula to improve its taste.
To reduce the risk of drug resistance, it is important to take the antibiotics as prescribedâand to completionâeven if you are feeling better. Stopping early or missing doses allows resistant bacteria to “escape” and proliferate, reducing the effectiveness of the antibiotic the next time around.
Nitrofurantoin is most effective if the doses are divided evenly throughout the day. If you have to dose every six hours, set an alarm clock to remind you. If a six-hourly dose is too difficult, ask your healthcare provider for 12-hourly Macrobid.
Nitrofurantoin capsules and oral suspension can be stored at room temperature, ideally between 68 to 77 F . Keep the medicine in a dry cupboard away from heat and direct sunlight.
