Levaquin vs Cipro
Introduction
For patients suffering from bacterial infections, certain antibiotics that target and kill the harmful bacteria are essential in managing symptoms and fighting off the infection. Levaquin (levofloxacin) and Cipro (ciprofloxacin) are two such drugs commonly prescribed for various types of bacterial infections. They both belong to a class of antibiotics known as fluoroquinolones, which interfere with bacterial DNA replication, thus inhibiting their growth. Even though these medications work similarly, they differ slightly in their specifics.
Levaquin is primarily used for treating serious respiratory tract infections like pneumonia while Cipro is typically used for urinary tract infections due to its higher concentration levels in urine after administration. It's important to note that while both these drugs can be effective at combating different bacterium caused diseases, they come with potential risks including tendon rupture or inflammation which should be considered when choosing an antibiotic treatment.
What is Levaquin?
Levofloxacin (the generic name for Levaquin) and ciprofloxacin (known as Cipro) are both part of the fluoroquinolone class of antibiotics, renowned for treating severe bacterial infections. Levofloxacin was first approved by the FDA in 1996. It works to kill bacteria or prevent their growth within the body, thereby aiding in curing many different types of infections. Similar to how Prozac selectively influences serotonin with only a minor influence on dopamine and norepinephrine, Levaquin has a broad spectrum effect against Gram-negative and Gram-positive bacteria but minimal impact on anaerobes, leading to fewer side effects compared to other antibiotics with stronger effects on these types of microbes. On the other hand, ciprofloxacin also treats various forms of bacterial infections but may have more side-effects due to its less selective nature when dealing with different bacteria types.
What conditions is Levaquin approved to treat?
Levaquin is approved for the treatment of various types of bacterial infections, including:
- Acute bacterial sinusitis
- Acute bacterial exacerbation of chronic bronchitis
- Community-acquired pneumonia
- Complicated skin and skin structure infections (in combination with other drugs)
- Uncomplicated skin and skin structure infections
- Chronic bacterial prostatitis
- Urinary tract infectious conditions (including pyelonephritis) in adults.
How does Levaquin help with these illnesses?
Levaquin, also known as levofloxacin, and Cipro, or ciprofloxacin, are both fluoroquinolone antibiotics that work to combat bacterial infections by interfering with the bacteria's ability to multiply. They do this by inhibiting a specific enzyme called DNA gyrase that is crucial for bacterial DNA replication. By blocking the action of this enzyme, these antibiotics prevent bacteria from duplicating and repairing their genetic material (DNA), thus stopping the spread of infection.
While Levaquin and Cipro belong to the same class of antibiotics and function similarly in terms of killing bacteria, there are some differences between them. For instance, Levaquin has a broader spectrum activity against different types of bacteria compared to Cipro. It can be used for more severe forms of pneumonia while Cipro is often reserved for urinary tract infections because it concentrates well within the kidneys and bladder.
As always with any medication regimen though it's important patients consult their healthcare provider before deciding on which antibiotic may best suit their needs given possible side effects or interactions with other medications they might be taking.
What is Cipro?
Cipro, the brand name for ciprofloxacin, is a broad-spectrum antibiotic that belongs to the fluoroquinolones class, which means it interferes with bacteria's DNA replication process. It was first approved by the FDA in 1987 and has been extensively used to treat a variety of bacterial infections since then. As Cipro is not directly comparable to Levaquin (levofloxacin), another fluoroquinolone antibiotic, it functions differently in terms of its spectrum and potency against certain types of bacteria. Its lack of activity on specific strains means its side-effect profile may also differ from that of Levaquin - most notably in regards to gastrointestinal issues such as nausea or diarrhea (common side effects among antibiotics like Levaquin). The benefits provided by ciprofloxacin can be crucial for treating various bacterial infections, especially those unresponsive or resistant to other "typical" antibiotics.
What conditions is Cipro approved to treat?
Cipro, also known as ciprofloxacin, is an antibiotic that has been approved by the FDA for treating a wide range of bacterial infections such as:
- Urinary tract infections (UTIs)
- Skin and bone infections
- Respiratory tract infections like pneumonia
- Bacterial diarrhea.
How does Cipro help with these illnesses?
Ciprofloxacin, commonly known as Cipro, is a broad-spectrum antibiotic that works by inhibiting the bacterial DNA gyrase enzyme, which is critical for the replication of bacteria. This mechanism effectively hampers the growth and multiplication of bacteria in the body. It's often prescribed for a variety of infections such as urinary tract infections, respiratory tract infections, and skin infections among others. Similar to Levaquin (levofloxacin), Cipro belongs to the fluoroquinolone class of antibiotics but it has a broader spectrum of activity against Gram-negative bacteria making it more suitable in situations where these types of bacteria are suspected or confirmed. However, like all fluoroquinolones, Cipro should be used with caution due to potential severe side effects including tendon rupture and negative impacts on mental health.
How effective are both Levaquin and Cipro?
Levofloxacin (Levaquin) and ciprofloxacin (Cipro) are both fluoroquinolones, a class of broad-spectrum antibiotics that have shown significant success in treating bacterial infections. They were approved by the FDA within a few years of each other, with Cipro receiving approval in 1987 and Levaquin in 1996. Both drugs work by inhibiting DNA gyrase and topoisomerase IV, enzymes necessary for bacteria to replicate their DNA.
In comparative studies, Levofloxacin has been found to be similar in efficacy to Ciprofloxacin for treating various infections such as urinary tract infections[1], respiratory tract infections[2], skin and soft tissue infections[3]. A meta-analysis released in 2010 demonstrated that both antibiotics showed comparable effectiveness for these types of bacterial infection.[4]
However, it's important to note that there may be some differences between the two medications when it comes to side effects. A study published in Clinical Infectious Diseases reported that patients taking levofloxacin were less likely than those on ciprofloxacin to stop treatment due to adverse events.[5]
These factors might make one drug preferred over another depending on patient-specific considerations such as comorbid conditions or potential interaction with other medications being taken concurrently.

At what dose is Levaquin typically prescribed?
Oral dosages of Levaquin (levofloxacin) range from 250-750 mg/day, depending on the type and severity of the bacterial infection. For most infections, a 500 mg/day dose is sufficient. Children and adolescents may be started on lower doses based on body weight. In either population, dosage can be adjusted after a few days if there is no response or if side effects occur. The maximum dosage that should not be exceeded in any case is 750 mg/day.

At what dose is Cipro typically prescribed?
Cipro (ciprofloxacin) treatment typically begins at a dosage of 250–500 mg every 12 hours. Depending on the severity and type of infection, your doctor might then increase the dose up to 750 mg every 12 hours. In some cases, if there is no significant improvement in symptoms or if the infection is particularly severe, your healthcare professional may test a maximum dose of up to 1500 mg divided into two doses per day spaced twelve hours apart. As with any medication, it's crucial not to exceed the prescribed dosage without consulting with your healthcare provider first.
What are the most common side effects for Levaquin?
Common side effects of Levaquin (levofloxacin) include:
- Headache
- Dizziness
- Gastrointestinal issues, such as nausea, diarrhea and constipation
- Insomnia (trouble sleeping)
- Changes in taste
- Abdominal pain or discomfort

- Vaginal itching and discharge
It's important to be aware that some individuals may experience more serious side effects such as tendonitis or tendon rupture. Always discuss potential risks with your healthcare provider before starting a new medication.
Are there any potential serious side effects for Levaquin?
While Levaquin and Cipro are both fluoroquinolones, they do come with their own potential side effects. For instance:
- Signs of an allergic reaction to Levaquin or Cipro could include difficulty breathing, hives, swelling in your face or throat.
- Some patients may experience a severe skin reaction that includes fever, sore throat, burning eyes, skin pain followed by a red or purple skin rash that spreads and causes blistering and peeling.
- Vision changes such as blurred vision, tunnel vision, eye pain or swelling could occur.
- Cardiovascular symptoms like fast heartbeats, chest flutters accompanied by shortness of breath and sudden dizziness might also be experienced.
- An imbalance of sodium levels in the body can cause headaches confusion slurred speech severe weakness vomiting loss of coordination unsteady feelings Severe nervous system reactions - rigid muscles high fever sweating confusion uneven heartbeats tremors feeling faint If you exhibit any symptoms related to serotonin syndrome: agitation hallucinations fever shivering fast heartbeat muscle rigidity twitching lack of coordination nausea vomiting diarrhea seek immediate medical attention.
Always consult your healthcare provider before starting these medications. If you have any adverse reactions while on either medication discontinue use immediately and seek professional help.
What are the most common side effects for Cipro?
Cipro, as compared to Levaquin, can have several side effects including:
- Nausea, diarrhea, and vomiting
- Headache or dizziness
- Abnormal liver function tests
- Rash or itching
- Sleep problems (insomnia)
- Dry mouth and throat discomfort
- Heart palpitations
- Confusion or agitation in some cases -Stomach pain and loss of appetite are also possible.
Excessive sweating may occur, although rarely. Musculoskeletal problems such as joint/muscle pain could be a rare but serious effect. It is important to note that while these potential effects might seem daunting, most people do not experience the full range of side effects listed here with Cipro.
Are there any potential serious side effects for Cipro?
Ciprofloxacin, commonly known as Cipro, is a widely used antibiotic. However, in rare cases it can lead to severe side effects that require immediate medical attention. These may include:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Symptoms associated with liver problems like stomach pain (upper right part), loss of appetite, dark urine coloration and jaundice (yellowing of the skin or eyes)
- Fast heartbeat or feeling light-headed
- Muscle weakness leading to trouble breathing
- Serious mood changes and unusual thoughts/behavior
- A seizure (convulsions) -Severe headaches with chest pain and severe dizziness
If you experience any of these symptoms while taking Ciprofloxacin, discontinue its use immediately and consult your healthcare provider.
Contraindications for Levaquin and Cipro?
Both Levaquin and Cipro, along with most other antibiotics, may cause side effects in some people. If you notice any severe reactions such as chest pain, severe dizziness or fainting, rapid heartbeat or sudden changes in your mental state like confusion or hallucinations after taking either of these medications, seek immediate medical attention.
Neither Levaquin nor Cipro should be taken if you are using tizanidine (a muscle relaxant) due to the risk of serious side effects. Always tell your physician which medications you are currently on; tizanidine will need a period of approximately 2 weeks to clear from your system before starting treatment with Levaquin or Cipro to prevent dangerous interactions.
Moreover, both drugs should not be used by persons with myasthenia gravis due to an increased risk of muscle weakness. Those who have a history of tendon disorders related to previous use of quinolone antibiotics should also avoid these two drugs. Both can also increase sensitivity towards sunlight so proper sun protection measures must be observed while undergoing therapy.
How much do Levaquin and Cipro cost?
For the brand-name versions of these drugs:
- The price of 10 tablets of Levaquin (500 mg) averages around $150, which works out to about $15/day, depending on your dose.
- The price for 20 tablets of Cipro (500 mg) is approximately $130, working out to roughly $6.50/day.
Thus, if you are in the higher dosage range for Cipro (i.e., 1000 mg/day or more), then brand-name Levaquin might be less expensive on a per-day treatment basis. However, this should not be a primary consideration in determining which drug is right for you as both have different indications and side-effect profiles.
As far as generic versions go:
- Levofloxacin (the generic version of Levaquin) can cost between $1 and $2 per day based on typical dosages.
- Generic ciprofloxacin costs significantly less at about $.30 to $.60 per day for common doses.
Remember that prices may vary depending upon your location, insurance coverage, and where you purchase your medication from.
Popularity of Levaquin and Cipro
Levofloxacin, known by the brand name Levaquin, was prescribed to approximately 6.1 million people in the US in 2020. As a fluoroquinolone antibiotic, levofloxacin is commonly used to treat various bacterial infections including pneumonia and urinary tract infections. It accounts for about 15% of total fluoroquinolone prescriptions in the United States.
Ciprofloxacin (brand name Cipro) on the other hand, had around 20 million prescriptions filled in America during that same year. Also belonging to the class of fluoroquinolones, it represents almost half of all fluoroquinolone prescriptions due to its broad-spectrum activity against both Gram-positive and Gram-negative bacteria. The use of ciprofloxacin has been steady over recent years despite concerns regarding potential adverse side effects associated with this group of antibiotics such as tendon rupture or peripheral neuropathy.
Conclusion
Both Levaquin (levofloxacin) and Cipro (ciprofloxacin) are potent antibiotics belonging to the fluoroquinolone class with a long-standing record of effectively treating various bacterial infections. They work by disrupting DNA replication in bacteria, leading to their death. Both can be used for treating similar conditions such as urinary tract infections, pneumonia, and skin infections but may also have specific indications based on the type of bacteria that they are most effective against.
Levaquin is often considered when a broader spectrum of activity is needed or when other first-line treatments haven't been successful. Cipro, on the other hand, has a narrower spectrum but it's particularly useful for certain types of gastrointestinal and urinary tract infections caused by E.coli.
Both drugs are available in generic form which represents significant cost savings especially for patients who must pay out-of-pocket. An adjustment period isn’t typically required as these antibiotics usually start working shortly after administration begins.
The side effect profiles between these two medications are quite similar; most commonly reported ones include nausea, diarrhea, headache and dizziness. However both carry black box warnings from FDA due to their potential risk to cause tendon damage or rupture especially in older adults; hence usage requires careful consideration by a physician taking into account patient's overall health status and history of prior antibiotic use. For both drugs patients should seek immediate medical help if they develop severe diarrhoea or signs indicative of tendon inflammation like pain/swelling.
