What Is Difluprednate?

Difluprednate (brand name Durezol) is a powerful corticosteroid eye drop used to treat inflammation and pain in the eye. It is FDA-approved for two main uses:

• Post-surgical eye inflammation — reduces swelling and pain after ocular surgery such as cataract removal
• Endogenous anterior uveitis — treats inflammation of the uveal tract inside the eye

It is also sometimes used off-label for posterior uveitis, diabetic macular edema, severe allergic conjunctivitis, and corneal graft rejection prophylaxis. Difluprednate is a synthetic difluorinated derivative of prednisolone, making it one of the most potent topical ophthalmic steroids available.

How does Difluprednate work?

Difluprednate works by inhibiting the release of inflammatory mediators — specifically prostaglandins and leukotrienes — in ocular tissues. By suppressing the immune response in the eye, it effectively reduces swelling, redness, and pain.

As a difluorinated prednisolone derivative, Difluprednate has enhanced penetration through the cornea compared to older ophthalmic steroids. This means it can reach deeper eye structures more effectively, making it particularly useful for treating both surface and deeper ocular inflammation.

The typical dosing regimen is 1 drop in the affected eye 4 times daily for 2 weeks after surgery, tapering to 2 times daily for a week, then gradually discontinuing as directed by your eye doctor.

What doses are available for Difluprednate?

• Ophthalmic emulsion 0.05% — 5 mL bottle (the only commercially available strength)

Difluprednate is available as both brand-name Durezol and as a generic ophthalmic emulsion, though generic supply has been limited due to the ongoing shortage.

How hard is it to find Difluprednate in stock?

Difluprednate has been affected by an active shortage since April 2024. Generic manufacturer Exelan placed its 0.05% ophthalmic emulsion on long-term back order with no estimated release date. This has made the generic version difficult to find at many pharmacies, pushing patients toward brand-name Durezol, which is more widely available but significantly more expensive.

With a findability score of 45 out of 100, you may need to call multiple pharmacies or use Medfinder to locate Difluprednate in stock near you. The brand-name Durezol is generally easier to find, though at a much higher cost.

Who Can Prescribe Difluprednate?

Difluprednate is primarily prescribed by eye care specialists:

• Ophthalmologists — most commonly prescribe Difluprednate, especially after ocular surgeries like cataract removal or for treating uveitis
• Optometrists — may prescribe Difluprednate for inflammatory eye conditions within their scope of practice

Because Difluprednate is a potent ophthalmic steroid that requires monitoring of intraocular pressure, it is almost exclusively managed by eye care professionals. Telehealth prescribing is generally not available for this medication since it requires in-person eye examinations.

Is Difluprednate a controlled substance?

No, Difluprednate is not a controlled substance. It is not classified under any DEA schedule. However, it is a prescription-only medication that requires a valid prescription from a licensed eye care provider. Because it is a potent corticosteroid, your doctor will need to monitor your intraocular pressure during treatment to watch for potential complications like glaucoma.

Common Side Effects of Difluprednate

Like all corticosteroid eye drops, Difluprednate can cause side effects. Most are mild and temporary:

• Eye irritation or discomfort
• Blurred vision
• Photophobia (sensitivity to light)
• Eye pain
• Foreign body sensation (feeling like something is in your eye)
• Headache
• Increased tearing

Serious side effects that require immediate medical attention include:

• Elevated intraocular pressure (IOP) that may lead to glaucoma
• Posterior subcapsular cataracts with prolonged use
• Secondary ocular infections (bacterial, fungal, or viral)
• Delayed wound healing
• Vision changes or vision loss

Your eye doctor will monitor your intraocular pressure during treatment. Report any sudden vision changes, increased eye pain, or signs of infection immediately.

Alternative Medications to Difluprednate

If you're having trouble finding Difluprednate in stock or need a more affordable option, ask your eye doctor about these alternatives:

• Prednisolone Acetate (Pred Forte) — a widely used ophthalmic corticosteroid available as an affordable generic; often used as first-line therapy for post-surgical inflammation and uveitis, though less potent than Difluprednate
• Loteprednol Etabonate (Lotemax) — a softer steroid eye drop with lower risk of elevated intraocular pressure; available as gel, suspension, and ointment for mild to moderate inflammation
• Dexamethasone Ophthalmic (Maxidex) — a potent corticosteroid eye drop with similar strength to Difluprednate; available generically at lower cost
• Fluorometholone (FML) — a milder ophthalmic steroid with lower risk of IOP elevation; best suited for surface eye inflammation rather than deep ocular conditions

Always consult your ophthalmologist before switching medications, as the right choice depends on the severity and type of your eye condition.

Drug Interactions with Difluprednate

Because Difluprednate is a topical ophthalmic medication with minimal systemic absorption, drug interactions are limited primarily to other eye medications:

• Other ophthalmic NSAIDs — using anti-inflammatory eye drops alongside Difluprednate may increase the risk of corneal healing problems
• Other corticosteroid eye drops — combining steroid eye drops raises the risk of elevated intraocular pressure and cataracts
• Anticholinergic eye drops — may further increase intraocular pressure when used together
• Other topical eye medications — wait at least 10 minutes between different eye drops to prevent dilution and ensure proper absorption

There are no known food interactions since Difluprednate is applied directly to the eye. Always tell your eye doctor about all medications you are currently using, including over-the-counter eye drops.

Final Thoughts on Difluprednate

Difluprednate (Durezol) is a highly effective ophthalmic corticosteroid for treating post-surgical eye inflammation and uveitis. However, the ongoing generic shortage since April 2024 has made finding this medication challenging and often more expensive for patients.

If you're struggling to find Difluprednate in stock, Medfinder can help you locate pharmacies that currently have it available. You may also want to ask your ophthalmologist about alternatives like Prednisolone Acetate or Dexamethasone, which are more widely available as generics.

For cost savings, look into generic Difluprednate with a discount card ($45–$120 per bottle), Novartis copay savings cards for brand Durezol, or the Novartis Patient Assistance Foundation for eligible uninsured patients.
