Vigamox vs Ciloxan
Introduction
For patients dealing with bacterial eye infections, certain antibiotics that interfere with the growth and multiplication of bacteria can help in treating these conditions. Vigamox (moxifloxacin) and Ciloxan (ciprofloxacin) are two such drugs commonly prescribed for eye infections. They each act by inhibiting different enzymes vital to bacterial DNA replication, but both have bactericidal effects in patients with eye infections. Vigamox is a fourth-generation fluoroquinolone antibiotic which has a broad spectrum activity against a wide range of bacteria including those resistant to older fluoroquinolones. On the other hand, Ciloxan, also belonging to the class of fluoroquinolones but being an earlier generation drug compared to Vigamox, primarily affects gram-negative bacteria like Pseudomonas aeruginosa.
What is Vigamox?
Moxifloxacin (the generic name for Vigamox) was the first drug of its kind in the fluoroquinolone class of antibiotics developed specifically to treat bacterial eye infections, a major advancement from previous classes of ocular antibiotics. Moxifloxacin was first approved by the FDA in 1999. It works by preventing bacteria from reproducing and repairing themselves, effectively reducing their presence within the eye over time. Vigamox is prescribed mainly for treating bacterial conjunctivitis caused by susceptible strains of certain bacteria.
Ciprofloxacin (the generic name for Ciloxan), also a part of the fluoroquinolone class, has been around longer than Moxifloxacin and used more broadly to treat various types of bacterial infections including those affecting eyes like corneal ulcers and conjunctivitis besides ear infections as well.
Both are effective at eradicating harmful bacteria but due to its narrower spectrum, Moxifloxacin tends to have fewer side effects compared with Ciprofloxacin which may affect more types of bacteria leading potentially to disruption in normal body flora.
What conditions is Vigamox approved to treat?
Vigamox is approved for the treatment of different types of bacterial infections:
- Bacterial conjunctivitis, also known as pink eye
- Corneal ulcers caused by susceptible strains of bacteria
- Preoperative prophylaxis in ocular surgery to prevent infection
How does Vigamox help with these illnesses?
Vigamox helps to manage bacterial eye infections by inhibiting the enzymes necessary for bacterial replication. It does this by blocking DNA gyrase and topoisomerase IV, two enzymes that are crucial in the process of bacteria duplicating their genetic material. DNA is a molecule that acts as a blueprint within every cell, playing an important role in cellular function, growth, reproduction, and survival. Bacteria with compromised ability to replicate their DNA cannot continue to multiply and spread infection. Therefore, by inhibiting these enzymes, Vigamox can limit the progress of bacterial eye infections and help patients manage their condition effectively.
On the other hand, Ciloxan also works against bacterial eye infections but via a slightly different mechanism than Vigamox. While it also targets DNA gyrase like Vigamox does; its effect on topoisomerase IV is less significant making it effective for a somewhat narrower spectrum of bacteria compared to Vigamox.
What is Ciloxan?
Ciloxan, a brand name for ciprofloxacin, is a fluoroquinolone antibiotic that interferes with the bacteria's DNA replication process. This action prevents bacterial reproduction and ultimately eradicates the infection. Ciprofloxacin was first approved by the FDA in 1987 and since then has become widely used due to its broad-spectrum antibacterial activity.
Unlike Vigamox (moxifloxacin), which is also an antibiotic but from the same class of drugs, Ciloxan does not primarily target DNA gyrase and topoisomerase IV - two essential enzymes involved in bacterial DNA replication. This difference means that their side-effect profiles are dissimilar; while both can cause local irritation when applied as eye drops, systemic side effects such as nausea or diarrhea are less common with Ciloxan compared to Vigamox.
The functionality on different kinds of bacteria makes it beneficial for treating various types of infections, especially those resistant to other antibiotics. Therefore patients who do not respond well or have allergies to “typical” antibiotics such as penicillins may find relief using medications like Ciloxan.
What conditions is Ciloxan approved to treat?
Ciloxan is a prescription medication that has been approved by the FDA for treatment of:
- Bacterial conjunctivitis (pink eye)
- Corneal ulcers caused by certain bacteria It's important to note that Ciloxan should only be used if prescribed by a healthcare professional, as it targets specific types of bacterial infections.
How does Ciloxan help with these illnesses?
Ciloxan, similar to Vigamox, is a fluoroquinolone antibiotic eye drop used for the treatment of bacterial infections in the eyes. It works by inhibiting DNA gyrase and topoisomerase IV which are essential enzymes needed by bacteria for replication, transcription, repair and recombination of their genetic material (DNA). This results in death of the bacteria cells and eradication of infection. However, Ciloxan has an added advantage as it covers a broader spectrum of pathogens including pseudomonas aeruginosa which is not effectively covered by Vigamox. While both medications have been shown to be effective against most common ocular pathogens; due to its wider coverage and low resistance profile among microorganisms, Ciloxan may be prescribed when a patient does not respond well to other typical antibiotics or can even be combined with other treatments where necessary.
How effective are both Vigamox and Ciloxan?
Both moxifloxacin (Vigamox) and ciprofloxacin (Ciloxan) are fluoroquinolone antibiotics, approved by the FDA for use in treating bacterial conjunctivitis. Due to their broad-spectrum activity against gram-positive and gram-negative bacteria, these eye drops can be prescribed under different circumstances depending on the suspected pathogen. A double-blind clinical trial in 2008 demonstrated that both Vigamox and Ciloxan had similar efficacy in managing symptoms of bacterial conjunctivitis as well as similar safety profiles.
A 2010 review indicated that starting from the first day of treatment with Vigamox, there was a significant reduction in ocular discomfort along with an improvement in visual acuity. It also showed a favorable side effect profile over many other antibiotic eye drops due to its preservative-free formulation which reduces potential allergic or toxic reactions.
On the other hand, Ciloxan has been widely used since its approval by the FDA back in 1990, making it one of the most commonly prescribed topical antibiotics for ocular infections worldwide. The dose showing optimal efficacy is typically every two hours while awake during the initial two days then every four hours during subsequent five days.
However, newer generation fluoroquinolones like Vigamox tend to be more frequently chosen nowadays because they offer better coverage especially against resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA). Despite this advantage, it should be noted that just like any other antibiotic misuse could potentially lead to increased bacterial resistance.
At what dose is Vigamox typically prescribed?
Topical dosages of Vigamox (moxifloxacin) usually consist of 1 drop in the affected eye(s) 3 times a day for 7 days. However, your doctor may adjust this based on your specific condition and response to treatment. In contrast, Ciloxan (ciprofloxacin) is typically used at a dosage of 1-2 drops into the affected eye every 2 hours for two days, then every four hours for five more days. As with any medication regimen, these dosages can be adjusted by your physician depending on the severity of infection and patient's response to therapy. It's important not to exceed recommended dosages without professional medical advice.

At what dose is Ciloxan typically prescribed?
Ciloxan treatment usually begins with one to two drops in the affected eye every two hours while awake for two days. Then, it can be reduced to one drop in the afflicted eye every four hours for an additional five days. If there is no response observed after a week of therapy, your ophthalmologist may consider testing a higher dosage or switching medications entirely. Like all antibiotic treatments, it's crucial not to discontinue Ciloxan prematurely as this could result in a return of the infection.
What are the most common side effects for Vigamox?
Common side effects of Vigamox include:
- Eye irritation, discomfort or pain
- Dry eyes
- Watery eyes
- Redness in the eye
- Blurred vision
- Puffy eyelids
On the other hand, common side effects of Ciloxan include:
- Burning or stinging sensation in the eye
- Redness and swelling around eyes
- Crusting on your eyelashes or eyelid corners
These are milder side effects that usually go away within a few days as your body adjusts to medication. However, if issues persist for longer than expected, consult with your doctor immediately. Please note this is not an exhaustive list and some people may experience other side effects.
Are there any potential serious side effects for Vigamox?
When comparing Vigamox and Ciloxan, it's important to know that both medications are generally well-tolerated and side effects are not common. However, in rare cases, patients could experience:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue or throat
- Eye discomfort or redness
- Watery eyes
- Vision changes like blurred vision or trouble focusing
In very rare instances a serious eye condition called corneal perforation may occur which can lead to symptoms including severe pain in the eye area and sudden changes in vision. If you experience any signs of this serious condition seek medical attention immediately.
Furthermore, while these drugs rarely affect heart rate directly if you do notice palpitations or unusually fast heartbeat when taking either Vigamox or Ciloxan contact your doctor right away.
Lastly remember that antibiotic medicines can cause diarrhea which may be a sign of a new infection. If you have diarrhea that is watery or bloody call your doctor before using anti-diarrhea medicine.
What are the most common side effects for Ciloxan?
The use of Ciloxan eye drops can lead to the following side effects:
- Irritation, burning or discomfort in the eyes
- Crusting or drainage from the eyes
- Blurred vision
- Eye redness or itching
- Sensitivity to light
- A sensation of something being stuck in your eye
- Mild skin rash around the eyes.
These symptoms are usually mild and temporary but if they persist or worsen, it is recommended that you consult with a healthcare professional.
Are there any potential serious side effects for Ciloxan?
Ciloxan, an antibiotic eye drop, is generally considered safe. However, in some cases, it may cause adverse reactions which include:
- Allergic reactions such as hives; difficulty breathing or swallowing; swelling of the face, lips, tongue or throat
- Serious skin reaction: fever with sore throat and severe blistering/peeling/red skin rash
- Vision problems including blurred vision and other changes in sight (such as seeing halos around lights)
- Eye pain or discomfort
- The development of a new infection
- Severe burning or itching after using the eye drops
- Unusual redness or swelling of your eyes
If you experience any of these symptoms while using Ciloxan eye drops, discontinue use and seek immediate medical attention.
Contraindications for Vigamox and Ciloxan?
Both Vigamox and Ciloxan, along with most other antibiotic eye drops, may cause some side effects such as irritation, burning or stinging sensation in the eyes. If you notice these symptoms worsening or if you experience severe reactions like swelling of the face or throat, difficulty breathing or signs of a serious allergic reaction, please seek immediate medical attention.
Neither Vigamox nor Ciloxan should be used if you are taking or have been using products that contain silver (such as colloidal silver), due to potential negative interactions. Always inform your physician about all medications and supplements that you are currently taking; silver-containing products will need to be discontinued for a certain period before starting treatment with either Vigamox or Ciloxan.
How much do Vigamox and Ciloxan cost?
For the brand name versions of these drugs:
- The price for a 3 ml eye dropper bottle of Vigamox (0.5%) averages around $180, which works out to roughly $6 per day if you use it four times daily as typically prescribed.
- The cost of a 5ml eye dropper bottle of Ciloxan (0.3%) is about $130, which works out to approximately $8.66/day when used three to four times daily.
Thus, although Vigamox has a higher upfront cost than Ciloxan, if you are in the higher dosage range for Ciloxan (i.e., using it four times a day), then brand-name Vigamox could be less expensive on a per-day treatment basis. Keep in mind that cost should not be your only consideration when determining which drug is right for you.
For the generic versions of these medications (moxifloxacin and ciprofloxacin), costs can vary significantly depending on factors such as location and insurance coverage:
- Moxifloxacin drops are available at prices from around $60 to $100 per 3ml vial.
- Generic ciprofloxacin drops usually run between about $15 and $50 for a similar-sized container.
Again, while moxifloxacin appears more costly outright but may provide better value over time with high-frequency usage due to its potency compared with ciprofloxacin.
Popularity of Vigamox and Ciloxan
Moxifloxacin, known by the brand name Vigamox, is a popular choice among ophthalmologists for treating bacterial eye infections. In 2020, it was estimated that about 1 million prescriptions were written in the US alone. Moxifloxacin accounts for just under 20% of fluoroquinolone ocular antibiotic prescriptions and has seen a steady increase in usage since its approval.
Ciprofloxacin, marketed as Ciloxan among others, is another commonly prescribed medication to combat bacterial eye infections. In the US during 2020, ciprofloxacin accounted for nearly 15% of fluoroquinolone ocular antibiotic prescriptions with nearly 800 thousand people being prescribed this treatment option. The prevalence of ciprofloxacin has remained approximately stable over the last decade.
Conclusion
Both Vigamox (moxifloxacin) and Ciloxan (ciprofloxacin) are well-established in the treatment of bacterial conjunctivitis, commonly known as "pink eye", and their efficacy is supported by numerous clinical studies. They are both antibiotics, but they belong to different subclasses within the fluoroquinolone class. Vigamox operates primarily on topoisomerase IV and DNA gyrase enzymes while Ciloxan works predominantly on DNA gyrase, which leads them to be prescribed under slightly different circumstances.
Vigamox is typically a first-line treatment option due to its broad spectrum coverage, whereas Ciloxan would usually be considered for patients who did not respond well to initial treatments or when specific bacteria sensitive to ciprofloxacin have been identified.
Both drugs come in generic forms representing potential cost savings for those paying out-of-pocket. The onset of action varies between individuals so it may take some time before effects become noticeable.
The side effect profile is similar between these two medications, generally being well-tolerated with minimal systemic absorption. However, local reactions such as irritation or discomfort at the application site can occur with either drug. It's important that patients closely monitor any changes after starting treatment including worsening symptoms or new symptoms appearing - if this happens medical help should be sought immediately.
