Vigamox is the brand name for moxifloxacin hydrochloride ophthalmic solution 0.5%, a prescription antibiotic eye drop used to treat bacterial conjunctivitis (pink eye). It is manufactured as a sterile, preservative-free solution and distributed in the United States by Novartis Pharmaceuticals Corporation.
Vigamox belongs to the fourth-generation fluoroquinolone class of antibiotics, offering broad-spectrum coverage against both gram-positive and gram-negative bacteria responsible for eye infections. It is FDA-approved for patients of all ages (1 year and older).
The standard dosing regimen is one drop instilled in the affected eye(s) three times daily for 7 days. Generic versions of moxifloxacin ophthalmic 0.5% are available from multiple FDA-approved manufacturers including Teva, Alembic, and Bausch Health.
We have a 99% success rate finding medications, even during nationwide shortages.

Vigamox (moxifloxacin) kills bacteria through a dual-target mechanism — simultaneously inhibiting two essential bacterial enzymes: topoisomerase II (DNA gyrase) and topoisomerase IV. These enzymes are critical for bacterial DNA replication, transcription, repair, and cell division.
By blocking both enzymes at once, moxifloxacin causes lethal breaks in bacterial DNA strands that cannot be repaired. Bacteria cannot replicate or survive without these enzymes, making moxifloxacin bactericidal (bacteria-killing) rather than merely bacteriostatic (bacteria-slowing).
After topical ophthalmic application, systemic absorption is minimal — mean plasma Cmax is approximately 2.7 ng/mL, about 1,600-fold lower than therapeutic oral doses. The drug acts locally in the infected eye tissue without significant whole-body exposure. Vigamox is self-preserved (contains no benzalkonium chloride), making it gentler on the ocular surface than many preserved ophthalmic antibiotics.
0.5% — ophthalmic solution
1 drop in affected eye(s) 3 times daily for 7 days; available as 3 mL bottle
As of 2026, Vigamox (moxifloxacin ophthalmic 0.5%) is not listed as an active national shortage on the FDA Drug Shortages database or ASHP shortage list. Multiple generic manufacturers supply the market, providing supply resilience. Overall, Vigamox is classified as generally available with a findability score of 80/100.
However, individual pharmacies can run out of stock temporarily due to seasonal surges in bacterial conjunctivitis cases (especially back-to-school season and winter), high ophthalmic surgical volume driving perioperative demand, and regional distributor delays. Patients may find one pharmacy out of stock while another nearby has it readily available.
If you're having trouble filling your Vigamox prescription, medfinder calls pharmacies in your area to check which ones have it in stock and texts you the results — saving you from calling each pharmacy yourself.
Because Vigamox is not a controlled substance, any licensed prescriber can write for it without special DEA registration or monitoring requirements. It can be prescribed via electronic prescription, phone call, or fax to any pharmacy.
Ophthalmologists — most common prescribers; handle both conjunctivitis and perioperative use
Optometrists (ODs) — licensed to prescribe antibiotics for eye infections in all 50 states
Primary care physicians (PCPs) and pediatricians — routinely diagnose and treat bacterial conjunctivitis
Urgent care physicians — commonly see and treat pink eye; no appointment needed
Nurse practitioners (NPs) and physician assistants (PAs) — can prescribe in all 50 states
Vigamox is also available via telehealth. Many telemedicine platforms (Teladoc, MDLive, Amazon Clinic, and others) offer same-day video consultations for conjunctivitis, and providers can e-prescribe Vigamox directly to your pharmacy during the visit.
No. Vigamox (moxifloxacin ophthalmic) is not a controlled substance and has no DEA scheduling. It has no abuse potential or dependency risk. This means Vigamox can be prescribed by any licensed prescriber — including primary care physicians, pediatricians, optometrists, nurse practitioners, and physician assistants — without the special DEA registration requirements that apply to controlled substances.
Prescriptions for Vigamox can be sent electronically, called in, or faxed to any pharmacy, and they can be refilled as directed by the prescriber. There are no quantity limits, early refill restrictions, or special monitoring requirements associated with its controlled substance status, because there is none.
Most patients tolerate Vigamox well. The most frequently reported side effects are ocular (affecting the eye) and typically mild and temporary:
Eye irritation or stinging upon application (brief, resolves within seconds to minutes)
Dry eye (ocular dryness)
Eye redness (ocular hyperemia)
Ocular itching (pruritus)
Temporary blurred vision immediately after instillation
Watery eyes (epiphora)
Serious allergic reaction: hives, difficulty breathing, swelling of face/lips/tongue/throat (anaphylaxis — rare but reported with quinolone antibiotics)
Severe or persistent burning, stinging, or irritation
Eye swelling beyond normal conjunctivitis
No improvement or worsening infection after 72 hours of treatment
New symptoms after initial improvement (possible fungal superinfection with prolonged use)

Ciprofloxacin ophthalmic (Ciloxan)
Second-generation fluoroquinolone eye drop; widely available as affordable generic ($10-$30); available in drops and ointment; broader gram-negative coverage but less gram-positive activity than moxifloxacin
Besifloxacin (Besivance)
Fourth-generation fluoroquinolone developed exclusively for ophthalmic use; excellent coverage including MRSA isolates; 3 times daily dosing; may have lower resistance risk due to ophthalmic-only development
Tobramycin (Tobrex)
Aminoglycoside antibiotic; non-fluoroquinolone option useful for Pseudomonas coverage in contact lens wearers; 4 times daily dosing; generic available
Polytrim (Polymyxin B/Trimethoprim)
Combination non-fluoroquinolone ophthalmic antibiotic; broad-spectrum; very affordable generic; useful when fluoroquinolones are unavailable or contraindicated

Other ophthalmic medications (concurrent eye drops)
minorWait at least 5 minutes between each ophthalmic medication to prevent dilution and ensure full absorption of each drug. Apply eye ointments last, waiting 10 minutes after drops.
Contact lenses
moderateDo not wear contact lenses during treatment. Contacts can trap bacteria and reduce drug effectiveness. Resume lens wear only after the infection has fully resolved and your doctor approves.
Oral moxifloxacin (Avelox)
minorConcurrent oral and ophthalmic moxifloxacin use results in very low combined systemic exposure. Inform your prescriber if taking oral moxifloxacin simultaneously, though clinical interaction significance is minimal.
Other fluoroquinolone antibiotics (allergy cross-reactivity)
majorIf allergic to any fluoroquinolone (ciprofloxacin, levofloxacin, ofloxacin, etc.), Vigamox is contraindicated due to potential cross-reactivity. Inform your provider of all antibiotic allergies before use.
Vigamox (moxifloxacin ophthalmic 0.5%) is a highly effective, well-tolerated antibiotic eye drop for bacterial conjunctivitis. Its fourth-generation fluoroquinolone profile, preservative-free formulation, and convenient three-times-daily dosing make it a preferred choice for ophthalmologists, optometrists, and other prescribers. With multiple generic manufacturers in the market, it is generally accessible and affordable with the right savings tools.
While not under a national shortage, individual pharmacy stock can be inconsistent — especially during peak conjunctivitis season or high surgical volume periods.
