Isopto Maxitrol (Neomycin Sulfate, Polymyxin B Sulfate, Dexamethasone)

Neomycin interferes with bacterial protein synthesis by binding the 30 S ribosomal subunit, while polymyxin B disrupts the bacterial cell‑membrane, causing rapid cell death. Dexamethasone activates glucocorticoid receptors, altering gene transcription to suppress inflammatory cytokines, reduce vascular leakage and limit leukocyte migration, thereby controlling ocular inflammation.

The dosing regimen for Isopto Maxitrol is determined by the prescribing clinician based on the severity of the infection, patient age and response to therapy. Typical instructions involve instilling one to two drops into the affected eye(s) at intervals specified by the healthcare professional.

Safety data for neomycin, polymyxin B and dexamethasone in pregnancy or lactation are limited. The product should be used only if the potential benefit outweighs any possible risk to the fetus or infant, and the decision should be made in consultation with a qualified healthcare provider.

Compared with single‑agent antibiotic drops, Isopto Maxitrol offers both antibacterial activity (neomycin and polymyxin B) and anti‑inflammatory action (dexamethasone) in one formulation, which can simplify treatment regimens. However, clinicians may prefer separate agents when a steroid is contraindicated or when targeting specific bacterial spectra.

The suspension should be stored at room temperature, away from direct sunlight and moisture. Keep the vial tightly closed when not in use, and discard any remaining product after the labeled period after opening, as recommended by the manufacturer.

Isopto Maxitrol is applied as an eye drop. The patient should wash hands, tilt the head back, pull down the lower eyelid to form a pocket, and place the prescribed number of drops into the conjunctival sac. Contact lenses should be removed before instillation and re‑inserted after a suitable interval.

Serious adverse events can include a rise in intra‑ocular pressure leading to glaucoma, secondary ocular infections such as fungal overgrowth, corneal ulceration, and severe allergic reactions that may threaten vision. Any sudden vision changes or intense eye pain should prompt immediate medical evaluation.

Patients with known hypersensitivity to neomycin, polymyxin B, dexamethasone or any component of the formulation should avoid the product. It is also contraindicated in viral eye infections like herpes simplex keratitis, and should be used with caution in individuals with uncontrolled glaucoma or ocular hypertension.
