Prescribing overview
This entry concerns sterile 0.5% ophthalmic ointment, not oral or dermatologic erythromycin. The reviewed label is human.
Key prescribing checks
- The cited label contraindicates use in patients with erythromycin hypersensitivity.
- Local irritation, redness and hypersensitivity may occur.
- Treatment depends on susceptible organisms and the ocular diagnosis; persistent or worsening signs warrant reassessment rather than assuming every red eye is a bacterial infection.
Uses by species

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.
Erythromycin
Reviewed human sterile ophthalmic ointment; human restrictions do not automatically establish veterinary contraindications.
Contraindications · when not to use
- History of erythromycin hypersensitivity.
Precautions & monitoring
- Nonsusceptible-organism/fungal overgrowth may require stopping and reassessing therapy. Avoid contaminating the applicator; local irritation/redness or hypersensitivity may occur. Pregnancy and nursing require professional assessment.
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
Local irritation, redness and hypersensitivity are reported in human labeling.
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
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.
Veterinary dose not verified; human ointment-ribbon directions omitted.
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
Persistent or worsening ocular signs need reassessment; nonsusceptible organisms, including fungi, may overgrow.
Client counseling
Do not touch the applicator tip to the eye, fingers or another surface.
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
Reviewed ointment: 15–25°C; retain sterile applicator hygiene.

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