The identified ingredients in this entry are not listed in the reviewed federal schedules. Prescription-only status, product restrictions and state law are separate questions.

STATE STATUS

Select a jurisdiction

Choose the state relevant to prescribing or dispensing. Patient residence alone may not determine every applicable rule.

What each federal schedule means

Highlighted rows match the verified federal or selected state schedule. The schedule describes legal control and abuse potential; it does not rank clinical usefulness or establish a dose.

Federal Schedules I–V: meaning and practice implications
Schedule	Meaning and practice
I	High abuse potential; no currently accepted medical use in U.S. treatment; lacks accepted safety under medical supervision. In practice: Not available for routine veterinary prescribing. Authorized research is a separate pathway.
II	High abuse potential; accepted medical use, sometimes with severe restrictions; abuse can cause severe dependence. In practice: No prescription refills under federal law. Strict prescribing, security and record requirements apply.
III	Less abuse potential than I or II; accepted medical use; abuse can cause moderate or low physical dependence or high psychological dependence. In practice: Federal prescriptions allow up to five authorized refills within six months. State rules may be stricter.
IV	Lower abuse potential than III; accepted medical use; limited dependence risk relative to III. In practice: The same federal five-refill / six-month prescription limit applies. Controlled-drug handling still applies.
V	Lower abuse potential than IV; accepted medical use; limited dependence risk relative to IV. In practice: Still controlled. Check authorized refills and state limits; do not automatically apply the III–IV refill rule.

What this means for the chart

For a controlled medication, confirm the prescriber’s authority for the applicable schedule, the exact formulation and quantity, authorized refills, secure handling, and required inventory / dispensing records. Check the state’s veterinary rules and any prescription monitoring program (PDMP) requirements or exemptions.

A PDMP reporting requirement does not by itself make a drug scheduled. “Not federally scheduled” does not mean over the counter, risk-free, or exempt from state law. States may use additional categories, such as Schedule VI, outside the federal I–V system.

VETERINARY TEAM REFERENCE · MEDICATION

Tobramycin

An aminoglycoside antibiotic. This entry covers the single-ingredient ophthalmic Tobrex product; systemic routes and combination products require separate identification.

Aminoglycoside ophthalmic antibioticProduct-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

Tobrex 0.3% ointment is a human external-eye product. Steroid-containing combinations, injections and inhaled preparations are separate products.

Key prescribing checks

Monitor for local irritation, eyelid swelling or hypersensitivity to topical aminoglycosides.
Assess the bacterial response; prolonged antibiotic exposure can permit resistant or nonsusceptible organisms to grow.
An ocular product is not intended for injection into the eye. Confirm the prescribed route and keep the applicator uncontaminated.

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.

Veterinary patients: not established by reviewed label

Extra-label veterinary use; reviewed ointment is human-labeled

Veterinarian-selected susceptible external ocular bacterial infection

Diagnosis and bacterial response require assessment; not every red eye is bacterial.

Use / indication source ↗

Pharmacology & pharmacokinetics

Mechanism and clinical role

Shows in-vitro activity against susceptible gram-negative and gram-positive ophthalmic bacteria; susceptibility cannot be assumed from appearance.

Absorption, distribution, metabolism and elimination

The reviewed ointment label does not establish species-specific veterinary ocular absorption or systemic disposition.

SAFETY REFERENCE · PRODUCT & SPECIES SPECIFIC

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.

Tobrex

Single-ingredient sterile ophthalmic ointment; Human product

Contraindications · when not to use

Hypersensitivity to any component.

Precautions & monitoring

Aminoglycoside cross-sensitivity and nonsusceptible overgrowth may occur; ointment can slow corneal healing. Not for intraocular injection.

Human labeling; this does not establish veterinary approval or animal-specific eligibility.

Safety sources checked: October 16, 2026. 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

Local irritation, eyelid itching/swelling and conjunctival redness; aminoglycoside hypersensitivity can become generalized. Ointments may slow corneal healing.

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 is not verified; human application amounts and intervals are not animal 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.

A product-specific interaction summary has not been established here. An empty list must not be interpreted as “no interactions.” Review the full source and a species-appropriate clinical reference.

Monitoring

Reassess bacterial response, corneal healing and possible nonsusceptible/fungal overgrowth with prolonged use.

Client counseling

Do not touch the tube tip to the eye or any surface. Never inject into the eye; stop and seek veterinary advice for suspected hypersensitivity.

This section supports the veterinary team's discharge discussion; it does not replace the product’s Client Information Sheet where one is required.

Storage & handling

Store Tobrex ointment at 2–25°C; follow the tube expiration and protect applicator cleanliness.
