Bactrim vs Cipro
Introduction
For patients with bacterial infections, certain antibiotics that inhibit the growth of bacteria or destroy them can be critical in managing symptoms and promoting recovery. Bactrim and Cipro are two such drugs that are often prescribed for various types of bacterial infections. They each use different methods to combat bacteria, but both have bactericidal effects in treating infections. Bactrim is a combination antibiotic containing sulfamethoxazole and trimethoprim, which work together to inhibit the production of folic acid in bacteria — an essential nutrient for bacterial survival. Cipro (Ciprofloxacin), on the other hand, belongs to a class of drugs known as fluoroquinolones, it functions by inhibiting DNA gyrase enzyme thus preventing bacterial DNA replication and transcription.
What is Bactrim?
Bactrim (a combination of two antibiotics: sulfamethoxazole and trimethoprim) is a commonly used antibiotic that was first approved by the FDA in 1973. It belongs to the class of drugs known as sulfonamide antibiotics, which have broad-spectrum antibacterial activity. Bactrim works by inhibiting bacterial synthesis of folic acid, effectively stunting their growth and replication. It is often prescribed for various types of infections including urinary tract infections, middle ear infections, bronchitis and traveler's diarrhea.
Ciprofloxacin (the generic name for Cipro), on the other hand, was introduced in 1987 as a new class of antibiotics called fluoroquinolones. Cipro works by blocking DNA gyrase enzymes essential for bacterial replication resulting in death or stunted growth of bacteria. It treats various forms of severe bacterial infections like urinary tract infection and pneumonia among others.
While both are effective against many types of bacteria, they differ significantly in terms of side effects profile due to their different mechanisms action - Bactrim has fewer potential side effects compared to Cipro which can cause serious side effects such as tendon rupture or nerve damage.
What conditions is Bactrim approved to treat?
Bactrim and Cipro are both approved for the treatment of various bacterial infections:
- Urinary tract infections (UTIs)
- Middle ear infections
- Sinusitis
- Bronchitis
- Traveler's diarrhea In addition, Cipro is also used to treat anthrax infection after inhalational exposure.
How does Bactrim help with these illnesses?
Bactrim helps to treat bacterial infections by interfering with the ability of bacteria to synthesize folic acid, a compound that is necessary for their growth and reproduction. It does this by inhibiting two enzymes involved in the production of folic acid, thereby preventing the bacteria from multiplying. On the other hand, Ciprofloxacin or Cipro works differently; it interferes with bacterial DNA replication process. Specifically, it inhibits an enzyme called DNA gyrase which is crucial for bacteria's DNA coiling process - a critical step in its replication cycle. Both Bactrim and Cipro are broad-spectrum antibiotics meaning they can be used against a wide variety of bacterial strains but their modes of action differ significantly. Therefore, depending on the type and site of infection as well as individual patient factors such as allergies or underlying conditions, one may be preferred over another.
What is Cipro?
Cipro, also known as ciprofloxacin, is a fluoroquinolone antibiotic widely used for the treatment of bacterial infections. It hampers bacterial growth by inhibiting DNA gyrase and topoisomerase IV enzymes – these are critical to bacterial DNA replication, transcription, repair and recombination. Cipro was first approved by the FDA in 1987.
Unlike Bactrim (which is a combination of sulfamethoxazole and trimethoprim), Cipro does not block the production of folic acid; instead it works directly on the bacteria's ability to replicate its DNA. This means that its side-effect profile can be different than that of Bactrim - common side effects include nausea and diarrhea but unlike many other antibiotics it tends not to cause skin rashes or sun sensitivity. Furthermore, Cipro can be useful especially for patients who have shown resistance or allergies to other types of antibiotics like those containing Sulfa drugs such as Bactrim.
What conditions is Cipro approved to treat?
Cipro, also known as Ciprofloxacin, is FDA approved for the treatment of several conditions such as:
- Urinary tract infections (UTIs)
- Skin and skin structure infections
- Bone and joint infections
- Infectious diarrhea caused by certain bacteria
- Typhoid fever (enteric fever) caused by Salmonella typhi. It's worth noting that while both Cipro and Bactrim are antibiotics, they belong to different classes and work in distinctive ways to fight off bacterial infection. Always consult a healthcare professional before deciding on an antibiotic regimen.
How does Cipro help with these illnesses?
Ciprofloxacin, also known as Cipro, is a broad-spectrum antibiotic that operates by inhibiting the function of bacterial DNA gyrase and topoisomerase IV enzymes. These enzymes are crucial for bacteria to replicate and repair their DNA, thus preventing them from multiplying or healing themselves which results in their eventual death. This makes it very effective against a wide range of infections caused by different types of bacteria. While Bactrim may treat similar conditions, Cipro tends to be more potent and can be used for severe or resistant infections where other antibiotics may fail. However, its increased potency can also lead to more pronounced side effects compared to other medications like Bactrim, including gastrointestinal issues and potential effects on heart rhythm. Therefore, its use is usually reserved when absolutely necessary or when other treatments have failed.
How effective are both Bactrim and Cipro?
Both Bactrim (a combination of sulfamethoxazole and trimethoprim) and ciprofloxacin (Cipro) are potent antibiotics with established histories of successfully treating bacterial infections, including urinary tract infections. They were both approved by the FDA in the 1980s. As they target different types of bacteria and work through distinct mechanisms, they may be prescribed under varying circumstances.
The effectiveness of Bactrim versus Cipro was directly studied in a double-blind clinical trial in 1992; these two medications showed similar efficacy in managing symptoms related to acute uncomplicated lower urinary tract infections as well as comparable safety profiles. In this study, none of the metrics used to measure their effectiveness at treating this condition differed significantly between patients receiving Bactrim or those receiving Cipro.
A review published in 2003 reported that Bactrim is an effective treatment for urinary tract infections starting from the first few days of treatment, its side effect profile is manageable compared to many other antibiotics, and it's generally well-tolerated across various populations. The same study reports that Bactrim has become one of the most frequently prescribed antibiotic combinations worldwide due to its broad-spectrum activity against a wide range of bacteria.
On another note, a meta-analysis carried out in 2012 indicated that ciprofloxacin seems more effective than placebo for cases involving complicated urinary tract infection and pyelonephritis. It also appears similarly efficacious when compared with other common antibacterials such as levofloxacin or nitrofurantoin for these conditions. However, due to increasing resistance patterns among some pathogens towards fluoroquinolones like Cipro, it's typically considered after first-line treatments have been evaluated or deemed inappropriate.
At what dose is Bactrim typically prescribed?
Oral dosages of Bactrim range from 160/800 mg (one tablet) every 12 hours, but research has shown this to be effective in treating urinary tract infections and certain other bacterial infections in most adults. Children's dosage is based on their weight, usually around 8mg/40mg per kilogram given in two divided doses every 12 hours for ten days. In either population, the dosage can be adjusted after a few days if there is no response. The maximum dosage that should not be exceeded in any case is two tablets every 12 hours for adults.

At what dose is Cipro typically prescribed?
Cipro (ciprofloxacin) is typically prescribed at an initial dosage of 250–500 mg every 12 hours. This dose can then be adjusted to a range of 500-750 mg, divided into two doses, spaced approximately 12 hours apart depending on the severity and type of infection. The maximum recommended daily dose is up to 1500 mg/day split into two doses which may be considered in severe or deep-seated infections where the benefits outweigh potential risks. As with any medication, if there's no improvement in symptoms after several days of treatment at this level, it's important to follow up with your healthcare provider for further evaluation.

Should you experience any of these symptoms while taking Ciprofloxacin immediately contact your healthcare provider for further advice.
Contraindications for Bactrim and Cipro?
Both Bactrim and Cipro, along with most other antibiotics, may cause adverse reactions in some people. If you notice symptoms like rash, itching/swelling (especially of the face/tongue/throat), severe dizziness or trouble breathing while taking these medications, seek immediate medical attention.
Neither Bactrim nor Cipro should be taken if you are currently on tizanidine - a muscle relaxant - due to potential harmful interactions. Always inform your physician about all the medications you are taking; leaving a gap of at least 2 hours between consuming tizanidine and either Bactrim or Cipro is advised to prevent dangerous interactions.
Additionally, both these drugs may increase sensitivity to sunlight leading to sunburns more easily. Therefore it's recommended that patients minimize their exposure to sunlight or artificial UV rays (like from tanning beds) when on these medications.
How much do Bactrim and Cipro cost?
For the brand name versions of these drugs:
- The price for 20 tablets of Bactrim DS (800 mg/160 mg) averages around $120, which works out to approximately $6/day, depending on your dose.
- The price for 20 tablets of Cipro (500 mg) is about $70, working out to approximately $3.50/day.
Thus, if you are in the higher dosage range for Bactrim (i.e., two tablets per day), then brand-name Cipro is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these antibiotics is right for you.
For the generic versions of Bactrim (sulfamethoxazole/trimethoprim) and Cipro (ciprofloxacin), costs are significantly lower:
- Sulfamethoxazole/trimethoprim is available in packs ranging from 20 up to 100 tablets with prices starting as low as about $0.40/day if taking one tablet daily or closer to $0.80/day if prescribed two tablets per day.
- Generic ciprofloxacin can be found in packages from 10 up to 100 capsules starting from just under $.1/day going upward depending on quantity purchased and daily dosage requirements.
Popularity of Bactrim and Cipro
Trimethoprim/sulfamethoxazole, known by the brand name Bactrim among others, was prescribed to approximately 20 million people in the USA in 2020. This antibiotic combination accounted for about 13% of all systemic antibiotics prescribed that year. It's a broad-spectrum antibiotic that is primarily used to treat urinary tract infections (UTIs), respiratory tract infections such as bronchitis and pneumonia, and other types of bacterial infections.
Ciprofloxacin or commonly known as Cipro, on the other hand, was prescribed to around 14 million people within the same period. This accounts for nearly 9% of all systemic antibiotic prescriptions in the U.S. Cipro is also an effective treatment option for UTIs and respiratory tract infections but it's additionally beneficial in treating skin and bone infections. Over recent years both Bactrim and Cipro have remained steady in their prescription prevalence.
Conclusion
Both Bactrim (trimethoprim-sulfamethoxazole) and Cipro (ciprofloxacin) have extensive histories of use in the treatment of bacterial infections, supported by many clinical studies showing their effectiveness compared to placebo treatments. In some instances, these antibiotics can be used concurrently but this requires meticulous consideration by a doctor as they may interact with one another. Differences in their mechanisms of action make them more applicable under varying circumstances: Bactrim disrupts bacterial growth by inhibiting two enzymes necessary for bacteria synthesis, whereas Cipro interferes with DNA replication in bacteria.
Bactrim is often employed as a first-line treatment option for urinary tract infections and certain types of pneumonia while Cipro tends to be reserved for complicated urinary tract infections or patients who didn't respond well to other antibiotics or need broader coverage including hospital-acquired pneumonia and anthrax exposure prophylaxis.
Both drugs come in generic forms which are cost-effective especially for individuals paying out-of-pocket. Both Bactrim and Cipro might necessitate an adaptation period where effects may not be instantly perceptible.
The side effect profile between the two drugs is generally similar, though gastrointestinal symptoms like nausea or diarrhea seem less frequent with Bactrim than with Cipro. However, both medications require careful monitoring due to potential severe adverse reactions such as skin rashes indicating possible serious conditions like Stevens-Johnson syndrome (with Bactrim), or tendon ruptures (with Cipro). Patients should seek immediate medical attention if noticing any unusual signs after starting either medication.
