Ophthalmic antibacterial combinationProduct-specific clinical reference

Updated October 16, 2026 · Sources and review status below

For veterinarians and veterinary staff. Product-label information is distinct from extra-label clinical practice. This is not a complete prescribing formulary or an automated interaction screen. Verify the current label, exact formulation, patient and species-specific clinical reference before use. Independent veterinary/pharmacy review remains pending.

Prescribing overview

Sterile antibiotic eye solution; it contains no corticosteroid.

Key prescribing checks

  • Avoid use with known hypersensitivity to any component; neomycin sensitization is a labeled concern.
  • Prolonged antibiotic use can permit nonsusceptible organisms to grow. Reassess persistence or worsening rather than substituting another abbreviated eye product without an examination.

Uses by species

Approval and evidence apply to the named product, species, route and indication. An extra-label use requires its own prescribing assessment; a human indication is not an animal approval.

Dogs and cats

Extra-label

Susceptible superficial bacterial ocular infection

Human-labeled product; veterinary diagnosis and prescription required.

Pharmacology & pharmacokinetics

Mechanism and clinical role

Contraindications & cautions

Contraindications identify circumstances where the source says a product should not be used. Precautions call for assessment or monitoring. Interactions identify combinations to review. They are distinct categories; this summary does not replace a full interaction check or the current product label.

Human-labeled Bausch + Lomb ophthalmic solution; veterinary use is extra-label.

Contraindications · when not to use

  • Known allergy to any ingredient.

Precautions & monitoring

  • Neomycin sensitization, resistant-organism overgrowth and bottle contamination can complicate treatment; never inject into the eye.

Safety sources checked: . Selected label information; independent veterinary or veterinary-pharmacy review remains pending. A label for dogs, cats, horses or humans does not establish safety for another species.

Adverse effects

Sensitization, local irritation and resistant-organism overgrowth are label concerns.

These are selected source-reported effects, not incidence estimates or an exhaustive list. Spontaneous postmarketing reports do not by themselves establish frequency or causality.

Dosing & administration

Verify the source before prescribing. The regimens below summarize selected veterinary product labels, not every accepted veterinary use. They are not automatic substitutions between brands or formulations. Renal/hepatic disease, concurrent therapy, age, indication and clinical response can require a different plan.

A verified veterinary dose has not been entered for this product. Human-label dosing must not be used as an animal regimen. Consult a current species-specific clinical source and the prescribing veterinarian.

A veterinary dose was not verified; human eye-drop schedules are not animal dosing instructions.

Extra-label prescribing and food-animal residue requirements are separate from labeled regimens. FDA extra-label-use guidance ↗

Drug & supplement interactions

This is a selected interaction reference, not an automated or comprehensive combination checker. Reconcile prescription drugs, nonprescription products, supplements and recent treatment changes.

Identified formulation

Human-labeled Bausch + Lomb ophthalmic solution; veterinary use is extra-label.

  • Allergic cross-reactions with other aminoglycosides are possible.

The cited product is a sterile ophthalmic solution, not a topical skin preparation.

Shared ingredients do not establish interchangeable concentrations, routes, release properties, species labeling or regional availability.
