Biaxin vs Levaquin
Introduction
For patients suffering from bacterial infections, certain antibiotics can help eradicate the infectious organisms and manage symptoms. Biaxin (clarithromycin) and Levaquin (levofloxacin) are two such drugs that are commonly prescribed for a variety of bacterial infections. They each work by inhibiting different stages in the life cycle of bacteria, but both have bactericidal effects in patients with an infection. Biaxin is classified as a macrolide antibiotic which works by blocking protein synthesis in bacteria, thereby preventing their growth and replication. On the other hand, Levaquin belongs to a class of drugs known as quinolone antibiotics; it serves to inhibit DNA gyrase or topoisomerase IV enzyme, disrupting DNA replication process within the bacterial cell leading to cell death.

What is Biaxin?
Clarithromycin (the generic name for Biaxin) is a macrolide antibiotic that was approved by the FDA in 1991. Biaxin works by inhibiting bacterial protein synthesis, effectively stopping the bacteria from growing and spreading in the body. It is primarily prescribed for treating infections caused by certain types of bacteria such as skin and respiratory system infections.
Levofloxacin (the generic name for Levaquin), on the other hand, belongs to a class of drugs known as quinolone antibiotics which came into existence after the development of first-generation fluoroquinolones. Approved by FDA in 1996, Levofloxacin also fights against bacteria in your body but it does so by inhibiting two topoisomerase enzymes which are required for bacterial DNA replication and repair.
While both medications are effective antibacterials, they differ significantly in their side effect profiles due to different mechanisms of action; Biaxin's impacts largely revolve around gastrointestinal issues like nausea or taste alteration whereas Levaquin may cause more serious effects including tendon rupture or peripheral neuropathy.
What conditions is Biaxin approved to treat?
Biaxin has been approved for the treatment of several types of bacterial infections including:
- Bronchitis and pneumonia caused by certain bacteria
- Strep throat and tonsillitis
- Sinusitis
- Skin infections
Levaquin, on the other hand, is used to treat a variety of bacterial infections, such as:
- Chronic bronchitis exacerbation
- Community-acquired pneumonia
- Nasal sinus infection (acute)
- Complicated skin and skin structure infections.
How does Biaxin help with these illnesses?
Biaxin, also known as clarithromycin, helps manage bacterial infections by inhibiting the production of proteins that bacteria need to divide and reproduce. It accomplishes this by binding to the subunit 50S of the bacterial ribosome, thus inhibiting translocation of peptides. Ribosomes are essential for protein synthesis in all living organisms, so by blocking their function in bacteria, Biaxin can curb bacterial growth.
Levaquin (levofloxacin), on the other hand, is a broad-spectrum antibiotic which works against a wider range of bacteria compared to Biaxin. Levaquin targets an enzyme called DNA gyrase in these cells. This enzyme is necessary for replication and repair of genetic material (DNA). By inhibiting this key enzyme, Levaquin prevents reproduction and ultimately leads to death of susceptible bacteria.
Both agents can be used effectively for different types of bacterial infections; however your healthcare provider will decide which one is more suitable based on your particular situation and type of infection.
What is Levaquin?
Levaquin, the brand name for levofloxacin, is a fluoroquinolone antibiotic that works by inhibiting bacterial DNA gyrase and topoisomerase IV enzymes. This prevents bacteria from replicating their DNA and thus stops them from multiplying. It was first approved by the FDA in 1996. As Levaquin is not a macrolide antibiotic like Biaxin (generic: clarithromycin), it does not work by preventing protein synthesis in bacteria. Its different mechanism of action means that its side-effect profile can also be distinct to that of macrolides such as Biaxin; for instance, it may cause less gastrointestinal upset but has been associated with more serious side effects including tendon damage and nerve problems (common side effects of fluoroquinolones). The powerful antibacterial effect of Levofloxacin can be beneficial for treating severe bacterial infections, particularly those resistant to 'typical' antibiotics such as clarithromycin.
What conditions is Levaquin approved to treat?
Levaquin is an antibiotic that has received FDA approval for the treatment of a variety of bacterial infections, including:
- Chronic bronchitis exacerbation
- Community-acquired pneumonia
- Urinary tract infections (UTIs)
- Acute pyelonephritis (kidney infection)
- Skin and structure infections Moreover, it can also be used as preventive treatment for people who have been exposed to anthrax.
How does Levaquin help with these illnesses?
Levofloxacin, often referred to by its brand name Levaquin, is a broad-spectrum antibiotic that works by inhibiting bacterial DNA replication. It's highly effective against a variety of infections caused by bacteria such as pneumonia and urinary tract infections (UTIs), making it an excellent choice in many cases. While Biaxin primarily targets respiratory system-related bacterial infections, Levofloxacin has the upper hand for its broad range of action across multiple parts of the body including skin, sinuses, kidneys, bladder or prostate. Furthermore, due to its different mechanism of action - disrupting DNA synthesis rather than protein synthesis like macrolides do (Biaxin belongs to this group) - Levaquin may be more potent against certain types of bacteria or preferred when patients are resistant or allergic to other antibiotics.
How effective are both Biaxin and Levaquin?
Both clarithromycin (Biaxin) and levofloxacin (Levaquin) are potent antibiotics with well-established efficacy in treating a range of bacterial infections. They were approved by the FDA within a few years of each other, Biaxin in 1991 and Levaquin in 1996. These two drugs work against different types of bacteria and thus may be prescribed under varying circumstances.
Clarithromycin is part of the macrolide group and has shown effectiveness against a wide array of gram-positive bacteria as well as some gram-negative microorganisms. It's commonly used to treat respiratory tract infections, skin infections, Helicobacter pylori infection, etc.
On the other hand, Levofloxacin belongs to the fluoroquinolone class and works broadly against both gram-positive and negative bacteria including pseudomonas aeruginosa – which is resistant to many antibiotic classes. It's often employed in cases such as complicated urinary tract infections, acute bacterial sinusitis or chronic bronchitis exacerbation.
A study conducted in 2002 compared these two antibiotics for their effects on community-acquired pneumonia; both demonstrated similar efficacy rates but Levofloxacin showed higher eradication rates for Haemophilus influenzae [1].

Furthermore, safety profiles reveal that while both medications can cause common side effects such as nausea or diarrhea - serious events seem less frequent with clarithromycin than levofloxacin which carries warnings about tendon rupture or peripheral neuropathy [2].
In conclusion; whether one drug would be chosen over another depends largely on type & severity of infection along with patient-specific factors like age or existing conditions.

At what dose is Biaxin typically prescribed?
Oral dosages of Biaxin typically range from 250-500 mg every 12 hours, but studies have indicated that a dose of 250 mg twice daily is sufficient for treating many mild to moderate infections in most people. Children are usually given 7.5-15 mg/kg every 12 hours depending on the severity and type of infection. For Levaquin, adults are typically prescribed a dosage ranging from 250-750mg once daily depending on the infection being treated. In either case, dosage can be adjusted after a few days if there is no response or if side effects occur. The maximum dosage should not exceed 1000mg/day for Biaxin and 750mg/day for Levaquin under any circumstances.
At what dose is Levaquin typically prescribed?
Levaquin therapy is typically initiated at a dosage of 250–500 mg/day, taken orally or intravenously once daily. The dose can then be increased up to 750 mg/day if necessary depending on the severity and type of infection. Treatment duration varies from a minimum of 5 days to a maximum of 60 days, based on the bacterial infection being treated. It's crucial to take Levaquin at evenly spaced intervals and complete the full course even if symptoms improve before completion. Inadequate treatment may result in an incomplete cure and foster antibiotic resistance.

If any such symptoms arise during treatment with either drug, immediately consult a healthcare professional.
What are the most common side effects for Levaquin?
Levaquin, a type of antibiotic, can cause side effects that may include:
- Upset stomach or diarrhea
- Headache or dizziness
- Mild skin rash or itching
- Symptoms of a cold such as stuffy nose and sore throat
- Difficulty sleeping (insomnia)
- Vaginal itching or discharge It's important to note that though these are common side effects, not everyone experiences them. In rare cases, Levaquin can also cause serious side effects like tendon rupture or nerve damage. Always consult with your healthcare provider about potential risks before starting any new medication.
Are there any potential serious side effects for Levaquin?
Levaquin, although highly effective in treating bacterial infections, can cause rare but serious side effects. These may include:
- Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Severe skin reactions: fever, sore throat, swelling in your face or tongue, burning sensation in eyes and skin pain followed by a red or purple rash that spreads (especially on the face or upper body) causing blistering and peeling
- Nervous system reactions: headaches, hallucinations, tremors and other symptoms indicative of central nervous system issues
- Changes to mood or behavior such as confusion or thoughts about suicide
- Symptoms related to vision problems like blurred vision.
- Heart rhythm changes (QT prolongation), which can be identified by fast/irregular heartbeat along with severe dizziness and fainting If you experience any of these side effects while taking Levaquin it is vital you contact medical assistance immediately.
Contraindications for Biaxin and Levaquin?
Both Biaxin and Levaquin, like many other antibiotics, may cause certain adverse reactions in some individuals. If you experience severe diarrhea, nausea or vomiting, skin rash or itching, sudden dizziness or fainting after taking these medications, please seek immediate medical attention.
Neither Biaxin nor Levaquin should be taken if you are consuming antipsychotics such as pimozide or ziprasidone due to dangerous drug interactions. Always inform your doctor about all the medications you are currently taking; Antipsychotic drugs will require a suitable washout period before initiating therapy with either Biaquan or Levaquin to prevent potentially life-threatening conditions like QT prolongation which can lead to serious irregular heart rhythms.
How much do Biaxin and Levaquin cost?
For the brand name versions of these drugs:
- The cost for 20 tablets of Biaxin (500 mg) averages around $290, which works out to approximately $14.50/day if taking a standard dose.
- The price for 10 tablets of Levaquin (750 mg) is about $130, which means roughly $13/day.
Hence, if you're prescribed the usual dosage range for Biaquin (i.e., 500 mg/day), then branded Levaquin might be less expensive on a per-day treatment basis. However, it's crucial to remember that cost should not be your primary consideration when deciding between these two medications.
As for generic versions - clarithromycin and levofloxacin respectively:
- Clarithromycin (500 mg tablets) can be purchased in packs ranging from 14 to 60 tablets with costs averaging between $1 and $4 per day depending on the quantity bought and your daily dosage.
- Levofloxacin is available in packages of up to several hundred pills with prices starting as low as about $.30 per day (for larger quantities upfront), but generally falls within the range of $.80-$2.00 per day based on typical dosaging protocols.
Popularity of Biaxin and Levaquin
Clarithromycin, commonly known by its brand name Biaxin, was estimated to have been prescribed to about 3.2 million people in the US in 2020. Clarithromycin accounted for approximately 10% of macrolide prescriptions in the US that year. It's a broad-spectrum antibiotic used against numerous bacterial infections and has remained relatively steady in prevalence over recent years.
Levofloxacin, sold under the trade name Levaquin among others, was prescribed to roughly 6 million patients across America during the same time frame. In terms of fluoroquinolone antibiotics, levofloxacin makes up around 18% of total prescriptions within this class and is commonly used for various types of bacterial infections including those related to skin or respiratory tract issues. Over the last decade, there has been a noticeable decrease in levofloxacin prescriptions due primarily to concerns regarding potential side effects associated with long-term use such as tendon rupture and peripheral neuropathy.
Conclusion
Both Biaxin (clarithromycin) and Levaquin (levofloxacin) have long-standing records of use in patients with bacterial infections, backed by numerous clinical studies indicating their effectiveness. They may sometimes be used together to treat certain types of infection, but this is subject to careful consideration by a physician due to potential interactions. The drugs function differently; Biaxin inhibits bacterial protein synthesis which stops the bacteria from growing, while Levaquin works by interfering with bacterial DNA replication and repair.
Biaxin is often chosen as first-line treatment for respiratory tract infections like bronchitis or pneumonia caused by susceptible organisms, whereas Levaquin may be selected when dealing with more serious conditions such as hospital-acquired pneumonia or complicated urinary tract infections.
Both medications are available in generic form representing significant cost savings especially for patients paying out-of-pocket. Both Biaxin and Levaquin may require an adjustment period meaning noticeable effects won't come right away.
In terms of side effects, both antibiotics are generally well-tolerated although they do carry risks including gastrointestinal disturbances and dizziness among others. For both drugs, it's important that patients monitor their reactions closely when starting treatment - any severe discomfort should prompt immediate medical attention.
