Loteprednol Etabonate is a prescription ophthalmic corticosteroid (steroid eye drop) used to reduce inflammation in the eye. It is sold under several brand names, including Lotemax, Lotemax SM, Alrex, Eysuvis, and Inveltys. The drug was FDA-approved in 1998 and is manufactured primarily by Bausch + Lomb.
Loteprednol Etabonate is used to treat post-operative eye inflammation after cataract surgery and other eye procedures, seasonal allergic conjunctivitis (Alrex 0.2%), dry eye disease (Eysuvis 0.25%), and various other inflammatory conditions of the ocular surface and anterior segment.
It is available in multiple formulations including ophthalmic suspension (0.2%, 0.25%, 0.5%, 1%), ophthalmic gel (0.38%, 0.5%), and ophthalmic ointment (0.5%). Generic versions are available for the 0.2% and 0.5% suspension and 0.5% gel formulations.

Loteprednol Etabonate is a "soft steroid" designed using retrometabolic drug design. It binds to glucocorticoid receptors inside eye cells, and the activated drug-receptor complex moves to the cell nucleus where it upregulates anti-inflammatory gene expression and suppresses pro-inflammatory cytokines, chemokines, and other mediators. This interrupts the inflammatory cascade at multiple points, reducing redness, swelling, and pain.
What makes Loteprednol uniquely safe is its rapid metabolic inactivation. After exerting its anti-inflammatory effect, enzymes in ocular tissue cleave the ester bond in the drug's structure, converting it to inactive metabolites (Δ1-cortienic acid) that have no meaningful biological activity. Plasma concentrations remain below detectable limits (<1 ng/mL) even with multiple daily doses over 42 days.
This mechanism explains Loteprednol's key clinical advantage: it has a significantly lower risk of elevating intraocular pressure (IOP) compared to traditional ophthalmic steroids. Clinical trials showed IOP elevation ≥10 mm Hg in only 2% of Loteprednol patients versus approximately 7% with Prednisolone Acetate 1%.
0.2% — ophthalmic suspension
Alrex — for seasonal allergic conjunctivitis; 1 drop 4x daily

0.38% — ophthalmic gel
Lotemax SM — post-operative; submicron technology; 1 drop 3x daily x 2 weeks
0.5% — ophthalmic suspension
Lotemax — ocular inflammation and post-op; 1-2 drops 4x daily x 2 weeks; generic available
0.5% — ophthalmic gel
Lotemax Gel — post-op inflammation; 1-2 drops 4x daily x 2 weeks; generic available
0.5% — ophthalmic ointment
Lotemax Ointment — post-op; ~1/2 inch ribbon 4x daily x 2 weeks
1% — ophthalmic suspension
Inveltys — post-operative; twice-daily dosing; 1-2 drops BID x 2 weeks
Loteprednol Etabonate is not on the FDA or ASHP drug shortage list in 2026. Supply is stable, and the drug is frequently recommended as an alternative when other ophthalmic steroids like Difluprednate and Fluorometholone face shortages. However, some patients still struggle to find their specific formulation.
The challenges are mainly about formulation variety and specialty stocking. Generic Loteprednol 0.5% suspension and 0.2% suspension are broadly available. Brand-only formulations like Lotemax SM (0.38%), Inveltys (1%), and Eysuvis (0.25%) are specialty products not stocked at every pharmacy. Seasonal demand for Alrex (0.2%) during spring and fall allergy seasons may also strain local inventory.

Loteprednol Etabonate is not a controlled substance and requires no special DEA authorization. Any licensed prescriber with authority to prescribe ophthalmic medications in their state may write for it. This includes physicians, optometrists, nurse practitioners, and physician assistants working within their scope of practice.
Ophthalmologists — most common prescribers; manage post-surgical and complex inflammatory cases
Optometrists (OD) — prescribing authority for therapeutic eye medications in nearly all U.S. states; common for allergic conjunctivitis and routine inflammatory conditions
Primary care physicians (MD, DO) — may prescribe for mild seasonal allergic conjunctivitis
Nurse practitioners and physician assistants — may prescribe within their scope at ophthalmology or primary care practices
Telehealth access is available for some indications. Seasonal allergic conjunctivitis (Alrex 0.2%) can often be evaluated and prescribed via telehealth platforms like Teladoc or MDLive. Post-operative prescriptions and complex inflammatory conditions require in-person examination.
No. Loteprednol Etabonate is not a controlled substance and has no DEA scheduling. It is a standard prescription-only ophthalmic medication that any licensed prescriber — including ophthalmologists, optometrists, primary care physicians, nurse practitioners, and physician assistants — can prescribe without special DEA authorization.
Because it is not scheduled, Loteprednol Etabonate prescriptions have no refill restrictions beyond standard prescription validity periods (typically 1 year). Electronic prescriptions and phone-in prescriptions to the pharmacy are permitted. There are no special prescription pads or tracking requirements associated with this medication.
Common side effects (occurring in 5–15% of patients) include:
Stinging or burning upon instillation (brief, typically 1–2 minutes)
Temporary blurred vision after application (especially with gel and ointment formulations)
Foreign body sensation
Mild eye discomfort or itching
Reflex tearing
Elevated intraocular pressure (IOP) — risk of glaucoma with prolonged use; occurs in ~2% of patients (lower than most ophthalmic steroids)
Posterior subcapsular cataracts — with prolonged use
Secondary ocular infections — steroids can mask or worsen infections including herpes simplex reactivation
Corneal or scleral perforation — rare, in patients with pre-existing tissue thinning

Prednisolone Acetate (Pred Forte)
More potent corticosteroid; widely available generic; less expensive; higher IOP elevation risk (~7% vs ~2% with Loteprednol); first-line post-op steroid at many practices
Dexamethasone Ophthalmic (Maxidex)
High-potency ophthalmic steroid; good for short-course treatment; generic available; higher IOP risk than Loteprednol
Fluorometholone (FML, FML Forte)
Similar low IOP-risk profile to Loteprednol; good for steroid responders; experiencing intermittent supply issues in some markets in 2026
Difluprednate (Durezol)
Most potent ophthalmic steroid; emulsion formulation; once or twice daily dosing; brand-name only; on ASHP shortage list since 2024; significantly more expensive

Other ophthalmic eye drops (concurrent use)
minorNo adverse chemical interactions, but spacing of at least 5 minutes between eye drops is required to prevent dilution and washout of medication.
Benzalkonium chloride + soft contact lenses
minorThe preservative in most Loteprednol formulations can be absorbed by soft contact lenses, potentially staining them or causing eye irritation. Remove contacts before use; wait 15 minutes before reinserting.
Glaucoma medications (latanoprost, timolol, brimonidine, etc.)
moderateLoteprednol Etabonate may partially counteract IOP-lowering effects of glaucoma drops in susceptible patients. Close IOP monitoring is required when combining ophthalmic steroids with glaucoma medications.
Herpes simplex eye disease (contraindication)
majorContraindicated with active herpes simplex epithelial keratitis. Steroid use in active HSV keratitis can dramatically worsen the infection and cause permanent corneal damage.
Active viral, fungal, or mycobacterial eye infections (contraindication)
majorContraindicated with vaccinia, varicella, fungal infections of ocular structures, and mycobacterial eye infections. Steroids suppress local immunity and can allow these infections to worsen dramatically.
Loteprednol Etabonate is one of the most widely used ophthalmic corticosteroids in the United States for good reason: it effectively controls eye inflammation while minimizing the risk of elevated intraocular pressure and systemic side effects that plague older steroid eye drops. Its "soft drug" design represents a genuine advance in ophthalmic pharmacology.
For patients, the most important things to know are: take the full prescribed course, remove contact lenses before use, have your eye pressure monitored if using it for more than 10 days, and never stop it abruptly after surgery without talking to your doctor. Generic formulations are bioequivalent and significantly more affordable — ask your prescriber if generic substitution is appropriate for you.
If you're having trouble finding Loteprednol Etabonate at your pharmacy or need help comparing prices, medfinder can help you locate pharmacies near you that have your exact formulation in stock.
