Macrobid vs Cipro
Introduction
For patients with urinary tract infections (UTIs) and other bacterial infections, certain antibiotics that inhibit the growth of bacteria can be instrumental in alleviating symptoms and combating infection. Macrobid and Cipro are two such drugs that are commonly prescribed for UTIs. They each target different aspects of bacterial cell function, but both have antibacterial effects in patients with these types of infections. Macrobid is a nitrofuran antibiotic which inhibits several bacterial enzyme systems, particularly those involved in glucose metabolism. On the other hand, Cipro belongs to a class called fluoroquinolones; it works by interfering with bacterial DNA replication process thus stopping their multiplication.

What is Macrobid?
Nitrofurantoin (the generic name for Macrobid) is a type of antibiotic that was introduced as an effective treatment for urinary tract infections (UTIs). Nitrofurantoin was first approved by the FDA in 1953. Macrobid works by killing the bacteria causing the infection, and it accomplishes this by damaging their DNA. It is prescribed mainly for treating UTIs caused by E. coli or Staphylococcus saprophyticus strains of bacteria.
On the other hand, Ciprofloxacin (Cipro) belongs to a different class of antibiotics known as fluoroquinolones and has a broader range of bacterial coverage than nitrofurantoin does. First approved in 1987, Cipro disrupts two enzymes necessary for bacteria to multiply which helps clear up infections more quickly.
While both medications can effectively treat UTIs, they have different side effect profiles due to their mechanisms of action: Macrobid's are usually limited to gastrointestinal discomfort while Cipro may cause more systemic effects such as tendon rupture and nerve damage in rare cases.
What conditions is Macrobid approved to treat?
Macrobid is approved for the treatment of various types of bacterial infections, including:
- Urinary tract infections caused by Escherichia coli or Staphylococcus saprophyticus
- Prevention of urinary tract infections recurrence during surgery or catheter use
- It's not recommended for pyelonephritis or perinephric abscesses due to insufficient evidence supporting its efficacy.
How does Macrobid help with these illnesses?
Macrobid, also known as nitrofurantoin, is used to treat and prevent urinary tract infections (UTIs) by killing bacteria in the bladder and urinary tract. It accomplishes this by damaging bacterial DNA, thus inhibiting their growth and reproduction. On the other hand, Cipro or ciprofloxacin operates on a broader spectrum of bacteria. This antibiotic prevents bacterial proliferation by interfering with enzymes that are critical for their replication process - specifically DNA gyrase and topoisomerase IV.
While both Macrobid and Cipro can be effective against UTIs caused by Escherichia coli (E.coli), each drug may be more effective for specific strains of bacteria or particular types of infections within the urinary system. Therefore, understanding your condition well can help you choose between these medications effectively.
What is Cipro?
Cipro is a brand name for ciprofloxacin, an antibiotic belonging to the fluoroquinolones group. It works by inhibiting bacterial DNA gyrase and topoisomerase IV enzymes, which are necessary for bacteria replication. This means it prevents the spreading of bacteria in the body and is therefore used to treat various types of bacterial infections. Cipro was first approved by the FDA in 1987.
Unlike Macrobid (nitrofurantoin) that specifically targets urinary tract infections caused by E.coli and Staphylococcus saprophyticus, Cipro has a broader spectrum including skin, bone, joint, stomach or intestinal infections as well as treating anthrax exposure.
However its side-effect profile differs from that of Macrobid; common side effects include nausea, vomiting and diarrhea but more serious adverse reactions such as tendon ruptures have been reported. Its broad range antimicrobial action can be beneficial especially when treating patients who do not respond well to other antibiotics.
What conditions is Cipro approved to treat?
Cipro, or ciprofloxacin, is approved by the FDA for a broad range of bacterial infections including:
- Urinary tract infections
- Lower respiratory tract infections
- Bone and joint infections
- Skin and skin structure infections
- Typhoid fever (enteric fever) caused by Salmonella typhi
It's also beneficial in treating severe sinus or bronchial infections, infectious diarrhea, anthrax inhalation exposure and certain sexually transmitted diseases like gonorrhea. It's important to note that Cipro should only be used for these conditions if they are caused by certain types of bacteria.
How does Cipro help with these illnesses?
Ciprofloxacin, commonly known as Cipro, is an antibiotic that belongs to the fluoroquinolones class of drugs. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes necessary for bacteria to copy and repair their DNA, thus leading to bacterial death. This makes it effective against a broad range of bacteria.
Like Macrobid (nitrofurantoin), Cipro is often used in treating urinary tract infections (UTIs). However, Cipro has a broader spectrum of activity against various types of bacteria compared to Macrobid. Additionally, because it can enter tissues well and has a long half-life allowing twice-daily dosing only, Cipro is also prescribed for more serious systemic or deep-tissue infections where other antibiotics may not be as effective.
Despite its effectiveness though, due to concerns about potential side effects such as tendon damage or heart rhythm problems, use of fluoroquinolones like Cipro are generally reserved for cases when no other suitable alternatives are available.
How effective are both Macrobid and Cipro?
Both nitrofurantoin (Macrobid) and ciprofloxacin (Cipro) are effective antibiotics with long histories of treating bacterial infections, primarily urinary tract infections (UTIs). They were initially approved by the FDA in 1953 and 1987 respectively. Since they act on different types of bacteria, they may be prescribed under different circumstances. The effectiveness of Macrobid and Cipro in combating UTIs was directly studied in multiple clinical trials; both drugs have consistently shown high efficacy rates as well as good safety profiles.
A meta-analysis conducted in 2001 reviewed numerous studies comparing these two antibiotics for UTI treatment. Results showed that while both medications effectively clear infection symptoms, patients taking Macrobid reported fewer side effects than those on Cipro. This could make Macrobid a preferable choice for some individuals who experience gastrointestinal upset or other adverse reactions from antibiotics.
Cipro is an extremely potent broad-spectrum antibiotic, making it suitable for severe or complicated infections where the causative microorganism may not yet be identified. However, its strength also means it's more likely to cause significant changes to gut flora and can come with serious side effects like tendon rupture or nerve damage.
Macrobid is generally preferred over broader spectrum agents like Cipro for uncomplicated UTIs due to its narrower range of impact on body's normal flora which reduces potential side-effects such as diarrhea or yeast infection. It does however require longer course of treatment compared to Cipro - usually seven days versus three.
Given recent concern about fluoroquinolone resistance among common uropathogens and increasing recognition of collateral damage caused by broad-spectrum antimicrobials including promotion of Clostridium difficile infection, use should ideally be reserved only when first-line therapies aren't appropriate.

At what dose is Macrobid typically prescribed?
Oral dosages of Macrobid for adults typically range from 50–100 mg every 12 hours, and it's usually used for treating urinary tract infections (UTIs). Children aged one month or older may be started on 5-7 mg/kg/day in divided doses. Dosage can be adjusted based on response to the medication. The maximum dosage that should not be exceeded in any case is 200 mg/day. In comparison, Cipro dosage ranges broadly depending upon the severity and type of infection but typically starts at 250-500mg every 12 hours for adults and varies greatly for children based on weight. Always consult your healthcare provider before starting either medication.
At what dose is Cipro typically prescribed?
Cipro (ciprofloxacin) treatment typically begins with a dosage of 250-750 mg taken every 12 hours. The dose can be adjusted based on the nature and severity of the infection being treated, but it should not exceed 1500 mg/day divided into two doses spaced approximately 12 hours apart. If there is no improvement in symptoms after a few days of therapy at this level, your healthcare provider may consider either increasing the dose or switching to an alternative antibiotic. Always follow your physician's advice when taking any medication, including Cipro.
What are the most common side effects for Macrobid?
Common side effects of Macrobid include:
- Nausea, vomiting
- Upset stomach, diarrhea
- Dizziness, lightheadedness
- Headache
- Gas and heartburn
On the other hand, Cipro has been known to cause:
- Nausea, diarrhea
- Dizziness, lightheadedness
- Trouble sleeping (insomnia)
- Rash or itching
- Abnormal liver function tests -Tendonitis/tendon rupture
If you experience any severe or persistent symptoms while taking either medication, it's crucial that you seek immediate medical attention.
Are there any potential serious side effects for Macrobid?
While Macrobid is generally well-tolerated, it can occasionally cause serious side effects such as:
- Symptoms of lung inflammation - difficulty breathing, sudden onset of fever or chills
- Signs of an allergic reaction: hives; difficult breathing; swelling in your face or throat
- Symptoms indicating liver problems: yellowing skin or eyes (jaundice), persistent nausea/vomiting, dark urine
- Neurological symptoms like numbness or tingling sensations in the extremities, muscle weakness and unsteady movement.
- Rapid heart rate or pounding in your chest.
On the other hand, Ciprofloxacin (Cipro) may lead to some significant adverse reactions including:
- Tendinitis and tendon rupture: severe pain/swelling in the joints especially within two months of treatment.
- Central nervous system issues leading to hallucinations, confusion and anxiety. -Severe sun sensitivity resulting in blistering peeling skin rash
For both drugs if you experience any unusual symptoms that are persistent or worsen over time get medical help right away.
What are the most common side effects for Cipro?
While using Cipro (Ciprofloxacin), you may encounter several side effects that are quite common:
- Nausea, vomiting, and diarrhea
- Headaches or dizziness
- Trouble sleeping and restlessness
- Abnormal liver function tests
- Rash or itching
- Abdominal discomfort and loss of appetite
- Increased heart rate or palpitations
- Muscular pain or bone pain
Remember to report any unusual symptoms to your doctor as some side effects can be serious such as tendon rupture, severe allergic reaction (anaphylaxis) or neurological problems.
Are there any potential serious side effects for Cipro?
While Cipro (ciprofloxacin) is generally well-tolerated, it can cause severe side effects in some cases. These include:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Severe dizziness, fainting, fast or pounding heartbeats
- Muscle weakness or trouble breathing
- Serious changes in mood or behavior - nervousness, confusion, hallucinations
- Seizures (convulsions)
- Painful or difficult urination -Skin rash -- no matter how mild.
In case you notice any of these symptoms after taking Cipro(ciprofloxacin), stop its usage immediately and seek urgent medical help. It's important to note that these are not the only possible side effects associated with this medication. Always consult a healthcare professional for accurate information.
Contraindications for Macrobid and Cipro?
Both Macrobid and Cipro, like other antibiotics, can cause side effects such as nausea, vomiting or diarrhea. If these symptoms persist or worsen, seek immediate medical attention.
Neither Macrobid nor Cipro should be taken if you are using a medication called tizanidine (Zanaflex), as it may result in severe interactions. Always inform your physician about all the medications you are currently taking; tizanidine should not be used together with either of these antibiotics because of potential serious negative reactions.
If you have a history of myasthenia gravis, use caution when considering Cipro as it could potentially exacerbate muscle weakness associated with this condition. Similarly, those suffering from kidney disease should discuss alternatives to Macrobid with their healthcare provider due to an increased risk of side effects.
Individuals allergic to any ingredients in Macrobid or Cipro must avoid them entirely; likewise for those who had previous adverse reactions to similar drugs like quinolones group for Cipro and nitrofurantoin class for Macrobid. Lastly, while taking either medication always stay well hydrated and avoid excessive exposure to sunlight and ultraviolet light due to increased skin sensitivity caused by both drugs.
How much do Macrobid and Cipro cost?
For the brand name versions of these drugs:
- The price for 14 capsules of Macrobid (100 mg) averages around $150, which works out to approximately $10.70/day.
- The cost of a 20-tablet pack of Cipro (500 mg) is roughly $170, translating to about $8.50 per day.
Thus, if you are on higher dosage ranges or longer courses for Cipro treatment, then brand-name Macrobid could potentially be less expensive on a per-day basis. However, it's crucial to remember that costs should not be the primary deciding factor when choosing between these two medications.
As for their generic counterparts:
- Nitrofurantoin (the active ingredient in Macrobid) can significantly reduce your expenses with prices ranging from about $0.60 to $1.30 per day depending upon the daily dose and where you purchase it.
- Generic ciprofloxacin also presents more affordable options compared to its branded version; typically costing between $0.40 and $1 per day based on dosage levels and pharmacy pricing practices.
Popularity of Macrobid and Cipro
Nitrofurantoin, available in brand form as Macrobid, was prescribed to approximately 7.6 million people in the United States in 2020. Nitrofurantoin made up around 11% of urinary anti-infective prescriptions nationwide. It has a specific niche for uncomplicated urinary tract infections (UTIs), and is recommended as first-line treatment by many guidelines due to its lower resistance rates compared to other antibiotics.
Ciprofloxacin, also known by the brand name Cipro, was given out to some 12 million Americans during the same time period. This accounts for just over 30% of fluoroquinolone antibiotic prescriptions countrywide and makes it one of the most commonly used antibiotics overall. Fluoroquinolones like ciprofloxacin are broad-spectrum antibiotics that can treat a wide variety of bacterial infections beyond UTIs; however they are generally considered second-line treatment for uncomplicated UTIs due to concerns about antibiotic resistance.
Conclusion
Both Macrobid (nitrofurantoin) and Cipro (ciprofloxacin) are widely used antibiotics with established efficacy in the treatment of urinary tract infections. They function by inhibiting bacterial growth, but their mechanisms of action differ: Macrobid interferes with bacterial enzymatic processes, while Cipro is a fluoroquinolone antibiotic that disrupts DNA replication in bacteria.
Macrobid is often considered as a first-line therapy for uncomplicated urinary tract infections due to its targeted nature and lower risk of contributing to antibiotic resistance. Meanwhile, Cipro has broad-spectrum activity against various types of bacteria and may be prescribed when other treatments have failed or for more complex cases.
Both drugs are available generically, which can significantly reduce costs for patients paying out-of-pocket. As with many medications, it might take some time before the full benefit from these antibiotics is observed.
The side effect profiles between the two drugs do overlap somewhat, but each also carries unique risks. While both generally well-tolerated, Macrobid may cause lung reactions and should not be taken by individuals with poor kidney function; meanwhile, Cipro carries a black box warning due to potential tendon damage and nerve issues it may cause. As always when taking antibiotics like Macrobid or Ciproflaxin patients should monitor any unusual symptoms closely and check-in regularly with their healthcare provider.
