When it comes to treating bacterial eye infections, choosing the right drop can feel like a maze of brand names, dosages, and side‑effect profiles. This guide cuts through the noise by putting Besivance side by side with the most common alternatives, so you can see what matters for efficacy, safety, cost, and convenience.
What is Besivance?
Besivance is an ophthalmic solution containing 0.5% besifloxacin, a fourth‑generation fluoroquinolone approved by the FDA in 2009 for bacterial conjunctivitis. It is supplied as a single‑dose bottle that patients instill one drop in the affected eye three times daily for seven days.
How Besivance Works
Besifloxacin, the active ingredient, inhibits bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication. This dual‑target action gives it a broad spectrum against Gram‑positive and Gram‑negative organisms, including resistant strains of Staphylococcus aureus and Streptococcus pneumoniae. Its formulation includes a proprietary cyclodextrin carrier that enhances corneal penetration while reducing ocular irritation.
Key Clinical Attributes of Besivance
- Indication: Acute bacterial conjunctivitis (ABCon) in patients 1 year and older.
- Dosage: 1 drop per eye, three times daily for 7 days (no loading dose).
- FDA Status: Prescription‑only, approved 2009.
- Safety profile: Most common adverse events are mild transient burning (≈10%) and blurred vision (≈5%).
- Cost: Branded price averages $120-$150 per bottle; no generic version is currently available in the U.S.
Common Alternative Ophthalmic Antibiotics
Below are the top alternatives physicians consider when Besivance isn’t an option due to cost, insurance coverage, or patient preference.
Moxifloxacin is a fluoroquinolone ophthalmic solution (0.5%) approved for bacterial conjunctivitis and keratitis. It is typically dosed four times daily for five days.
Ciprofloxacin is a second‑generation fluoroquinolone eye drop (0.3%) used for a wide range of bacterial eye infections, dosed every two hours for the first day then four times daily.
Ofloxacin is a third‑generation fluoroquinolone (0.3%) with activity against many resistant strains, often prescribed three times daily for seven days.
Tobramycin is an aminoglycoside eye drop (0.3%) that targets Gram‑negative bacteria; dosing is typically four times daily for five to seven days.
Azithromycin Ophthalmic Solution is a macrolide formulation (1%) that offers once‑daily dosing for bacterial conjunctivitis, favored for its convenience.
Gatifloxacin is a fluoroquinolone (0.3%) used off‑label for eye infections; it provides a twice‑daily regimen but lacks FDA approval for conjunctivitis.

Pros and Cons: When to Choose Besivance
Advantages
- Once‑daily dosing isn’t required, but the three‑times‑daily schedule is easier than the Q2H regimen of ciprofloxacin.
- Excellent activity against fluoroquinolone‑resistant strains, thanks to the cyclodextrin carrier.
- Low incidence of systemic absorption; safe for pediatric patients down to 1year.
Drawbacks
- Higher out‑of‑pocket cost, especially for uninsured patients.
- No generic option yet, limiting formulary inclusion.
- Three‑day dosing may be missed by patients with poor adherence.
Choosing the Right Alternative for Specific Scenarios
- Budget‑conscious patients: Ciprofloxacin or generic moxifloxacin provide comparable efficacy at a fraction of the price.
- Patients with compliance concerns: Azithromycin’s once‑daily schedule can improve adherence, though its spectrum is narrower.
- Suspected Pseudomonas infection: Tobramycin remains the go‑to due to its strong Gram‑‑ coverage.
- Allergy to fluoroquinolones: Switch to an aminoglycoside (tobramycin) or macrolide (azithromycin) to avoid cross‑reactivity.
- Need for rapid bacterial eradication: Besivance’s enhanced penetration may shorten symptom resolution by 1‑2days compared with older fluoroquinolones.
Practical Prescribing Checklist
- Confirm bacterial etiology (purulent discharge, lid swelling, rapid onset).
- Check patient’s insurance formulary for coverage of Besivance versus generics.
- Ask about prior fluoroquinolone exposure - resistance may tip the scale toward Besivance.
- Assess adherence potential: choose once‑daily azithromycin if daily dosing is critical.
- Document any known drug allergies, especially to quinolones or aminoglycosides.
- Schedule a follow‑up in 48‑72hours to ensure clinical improvement.
Frequently Asked Questions
Is Besivance effective against MRSA‑related eye infections?
Yes. In vitro studies show besifloxacin retains activity against many methicillin‑resistant Staphylococcus aureus (MRSA) strains, largely because its cyclodextrin carrier boosts corneal concentration beyond the MIC of resistant isolates.
Can I use Besivance for viral conjunctivitis?
No. Besivance targets bacterial DNA replication and offers no benefit for viral or allergic conjunctivitis. Using it in those cases adds cost without improving outcomes.
How does the cost of Besivance compare to generic moxifloxacin?
A typical Besivance bottle runs $120‑$150, whereas a 7‑day course of generic moxifloxacin costs $20‑$30. The price gap can be a deciding factor for patients without supplemental insurance.
Are there any drug‑interaction concerns with Besivance?
Because Besivance is applied topically and systemic absorption is minimal, interactions are rare. However, concomitant use of other ophthalmic fluoroquinolones should be avoided to reduce the risk of additive toxicity.
What should I do if a patient experiences severe burning after the first drop?
Mild burning is expected, but severe or persistent discomfort warrants discontinuation and a switch to an alternative (e.g., azithromycin). Document the reaction and advise the patient to report any worsening symptoms.

October 17, 2025 AT 15:10Regarding the pharmacodynamics, besifloxacin demonstrates superior corneal penetration due to cyclodextrin inclusion.

October 21, 2025 AT 02:30Listen, if you can swing the price, the three‑daily schedule beats the q2h nightmare of ciprofloxacin – you’ll see clearer eyes sooner.

October 24, 2025 AT 13:50Let’s dissect the data with a bit of rigor: the table plainly shows Besivance sits in the $120‑$150 bracket, a stark contrast to the $20‑$30 range of ciprofloxacin. While the price hike may raise eyebrows, the clinical literature cites a marginally faster symptom resolution, typically by one to two days, owing to the cyclodextrin carrier that boosts ocular bioavailability. Side‑effect rates remain low-burning in roughly ten percent and blurred vision in five-so the safety profile isn’t dramatically worse than the alternatives. However, the lack of a generic version hampers formulary inclusion, making it a tough sell for cash‑strapped patients. In practice, I’d reserve Besivance for cases where resistance to older fluoroquinolones is documented or suspected. For routine uncomplicated conjunctivitis, a generic fluoroquinolone or azithromycin often suffices and spares the pocket.

October 31, 2025 AT 12:30Hey folks, let’s take a step back and look at the bigger picture when we talk about eye drops. 😃 The cost of a medication is never the only factor; adherence, side‑effects, and bacterial resistance patterns matter just as much. Besivance, with its innovative cyclodextrin carrier, does a great job of getting the drug where it needs to be, which can mean a quicker bounce‑back for patients who can afford it. 😌 On the other hand, the generic fluoroquinolones like moxifloxacin or ciprofloxacin have proven track records, are pocket‑friendly, and are widely available, making them a solid first‑line choice for many. 💡 If a patient is dealing with a resistant strain, especially MRSA‑like organisms, the broader spectrum of Besivance can be a lifesaver, literally preventing a potential vision‑threatening infection. 🌟 For those with compliance concerns, the once‑daily azithromycin is a real game‑changer; you drop it in the morning and forget about it. 🗓️ And let’s not forget the importance of patient education – explaining how to apply drops properly can reduce irritation and improve outcomes across the board. 🙏 Lastly, insurance formularies often dictate what’s actually reachable for a patient, so it’s wise to have a conversation with the pharmacy team early on. 😃 In short, there’s no one‑size‑fits‑all; we need a toolbox of options and the wisdom to pick the right tool for each individual case. 🌈
